Not as much to post about the past two weeks as I have been out of commission after hurting my back badly when I tripped and fell last week and aggravated the four cracked discs I have had from a nasty motorcycle accident over 25 years ago. But the spasms are lessening each day since and just a matter of time before I’m back to just the usual back ache which is my normal state. No complaints from me though as we continue to enjoy taking our time to weave our way generally north through some of the hundreds of postcard like Bahamian islands.
When I left off in the last post we were in Red Cut Cay and after a few days there we continued up and anchored at Black Point then on to Allen’s Cay and then a very neat fully enclosed very tiny little bay on Royal Island as seen here on our chart plotter. This will give you a better perspective on how small the entrance was and if you click on the photo I have circled in RED the two short pieces of white PVC pipe that marked each side. Captain Christine guided us through as she put the entrance in our wake and …… …… I soon had the anchor down into the sandy bottom 2.5m/8ft below and we were soon enjoying our very own little anchorage with wine up in the SkyBridge. THIS is why we worked on the design so hard with Dennis to have the least draft possible; 1.3m/4.4 ft After Royal Island we made our way over to Lynyard Cay where we anchored for four days and had a chance to meet up with some sailing friends Mark & Shawnae who were anchored nearby on their latest boat s/v Big Sky Blue Waters (they hail from Montana). Difficult to show on maps as most of these spots are too small to show up but you can get a rough idea of our route and anchorages along the way. We are now anchored up near the north end of Great Abaco Island just off of Coopers Town. There is a storm front coming through this weekend with winds out of the West and South rather than the usual Easterlies so we’ll wait out here for that to pass and then make our way West as we get ready to jump off and cross over to West Palm Beach area in Florida in the next week or so.
That catches you up on our most recent travels and anchorages and now I thought that something a bit different might be of interest to many of you. Read on to see what you think and let me know your thoughts with comments in the “join the discussion” box at the end please.
Year in Review: Top Features We Like Most and Least on Möbius
Hard to believe but we started writing this Mobius.World blog back in March 2018 so we’ve just passed the five year mark for that and the primary motivation for creating and writing the 262 posts since then has been the hope that sharing our experiences here provides a good way for us to “pay it forward” for all the other people who went before us and shared their experiences from which we learned SO much. In keeping with that hope, as the calendar turns over to May (how did THAT happen so fast??) we have been actively cruising Möbius for one year now. Also on the hard to believe list is that our log book shows that we have just ticked over 7300 nautical miles (8400 miles/13,520 Kilometers) and most of that in just the last six months since leaving Turkey at the end of October. Last year we were in and out of a number of marinas so we have been through our share of Med mooring, docking, fueling up and the like. This year we’ve been on anchor every night for the past four months in quite a variety of conditions, bottoms and weather. We’ve done everything from short day trips, lots of overnight passages and some longer ones such as our trans Atlantic crossing of 14 days. With these cumulative experiences I thought now would be a good time to reflect on what we have learned over the past year about what is working out best for us as well as what has not worked so well and we would change or do differently to make Möbius even better. I will write this up as two blog posts grouping what’s worked best into one and then a second with what changes we would make to follow. In my experience I have found that first hand experience from others has proven to be the best and most useful for making my decisions and so I hope these twin posts will do likewise for some of you.
A few caveats before I go any further:
All of the points I’ll be covering are simply what has worked so well or not for us and our use cases with no suggestion that these would be best for other owners, boats and use cases.
There is no implied order or ranking of these items, simply a list.
Any mention of specific products is done for clarity only, these are not endorsements and we have no sponsors or affiliations with any of the products mentioned.
In the years of posts here on this blog, I have provided lots of detailed coverage, too much perhaps, of each of these items during the build so in this posting I will just be listing the reasons why each item is on the list. If you are interested in more details you can refer to these previous posts and I’ll provide links to some of these.
OK, with that out of the way, let’s jump right into our top favorite features on Möbius.
Anchor system
Starting up at the Bow, our whole anchoring system has proven to be eXtremely strong, reliable and easy to use and has perhaps contributes more than any other system to our SWAN factor that enable us to Sleep Well At Night in every anchorage in all conditions. The “SideWinder” mounting of the anchor off the Port side of the Bow which Dennis and I designed, has proven to be a great setup eliminating the anchor and roller assembly from sticking out over 1m at docks and keeps it very securely pressed against the hull in pounding seas with nary a sound or any movement. The primary components of our Anchoring System are
110Kg/242lb Rocna anchor
100m/330ft of Galvanized DS40 13mm chain
Maxwell windlass VWC4000 w/Maxwell controls at both helms and wired remote in forepeak
Lewmar Deluxe Heavy Duty Chain Stopper 13mm chain
Lewmar EVO 55 Self-Tailing Winch for kedging The chain all stows inside of a round aluminium chain bin inside the forepeak which has worked out eXtremely well as there is no “castling” of the chain as it is stowed. and any anchor mud and muck that gets in there is easily flushed out through the drain in the bottom that exits out the side of the hull just above the waterline.
Once the anchor is set we attach a 25mm/1″ nylon snubber line using a loop of Dyneema with a slip knot that goes through one link on the chain. This takes seconds to attach or remove and the snubber from the chain and absorbs of any shock loads on the anchor chain and eliminates any chain noise into the boat. Letting the chain out until the snubber is taking all the tension the line comes up through the large round “nose cone” in the very front of the Bow and ties to the Samson post. Leading the snubber line through the center of the Bow reduces side to side swinging at anchor and the hyperbolic curve machined on the inside of the sold AL snubber cone prevents chaffing of the line which still shows no sign of chaffing after over 150 nights at anchor so far. The large degree of forward slope of the anchor deck also worked out great making it easy to hose down with all the debris draining out the nose cone back into the sea. All together this is a super dependable and easy to deploy/retrieve anchor system that sets first time every time and resets immediately on severe wind shifts. Depends on water depth of course but typically we have about 30m/100ft of 13mm anchor chain out which adds an additional 120kg/265lbs to the 110kg/242lbs of anchor on the bottom so we SWAN very well every night and is definitely one of our favorite systems!
Foul Release silicone bottom paint
Our last minute decision to go with silicone based “Foul Release” bottom paint instead of CopperCoat has turned out to be one of THE best decisions we made. This Foul Release type of bottom paint never ceases to amaze me with how it prevents almost anything from growing on it and what might be there after months of sitting still comes off completely with a simple wipe with a sponge or cloth to bring it back to like new. We used the International version called InterSleek 1100SR but several other manufacturers such as Hempel “Silic One” are also available. This paint has been in the water for over two years now and it still cleans up completely with just a sponge or cloth if we’ve been sitting at anchor for a long time and currently shows no sign of wear or age. It is supposed to be good for 5-7+ years and so far looks like it will achieve that easily which would be a HUGE benefit in terms of efficient hull speeds and no costly annual haul outs. I can’t say for sure but I think that having such clean and slippery silicone hull surface contributes to our overall hull efficiency, speed and great fuel burn rates. What’s not to like??!!
Open and Accessible system installation
All of the system components, wiring and plumbing were given dedicated locations with completely open access. This reduced the time for initial installation during the build but more importantly continues to put a smile on my face every time I need to do any work or maintenance on any of the systems as everything is easy to access and mounted at a just right height for working on. Here in the Basement for example you can see how all the components such as all the 14 MPPT controllers on the Left and the three 240V Victron Multiplus inverter/chargers on the Right, are all mounted such that when I’m kneeling or sitting in front of them they are at the just right height right in front of you to see and work on. Same story back in the Workshop area where all the major components on the Right such as the DC Distribution box, Kabola diesel boiler, watermaker and AirCon chiller system are mounted on top of the shelves to put them at just right height as well. At the far end, the front of the Day Tank has been used to mount all the fuel filters, Alfa Laval centrifuge and fuel transfer valve manifolds are out in the open and at perfect height when standing in front of them. Underneath that shelf the electrical wiring, external rectifiers and water distribution manifolds are also open and easy to access.
All of the plumbing is similarly open and easy to access such as this manifold with valves for all the cold water consumers in the Master Cabin.
One of our four primary principles for the design and build of Möbius was Low Maintenance and having all the components, wiring and plumbing open and so easily and comfortably accessed has been a big factor in achieving this goal throughout the whole boat.
Propulsion Perfection:
As we did for all the major components, we took a “systems” approach to the propulsion system from front of the engine to the prop. coupled to a Nogva Controllable Pitch Propeller (CPP) is also way up at the top of our list of favorite features on Möbius.
Our choice of a Gardner 6LXB engine aka Mr. Gee, coupled to a Nogva Controllable Pitch Propeller (CPP) via a Nogva HC-168 2.95:1 reduction gearbox is also way up at the top of our list of favorite features on Möbius.
The combination of the slow revving engine and lack of any transmission shifting created a seamless and smooth propulsion system. This was our first experience with CPP and it did take some time to learn how to run a boat where you first set the throttle at the RPM you want and then don’t touch it and just use the Pitch lever to increase pitch through an infinite range from zero/neutral to maximum pitch for the load and speed you want. With no shifting involved to go from forward to reverse it is eerily quiet and smooth when docking and when underway we essentially run the boat based on the EGT or Exhaust Gas Temperature meter to get the just right pitch for any speed we want.
We cruise between 8.5-9 knots and after 7300 nautical miles our overall propulsion efficiency has us averaging about 1.85 L/NM @ 8.5kts which we are eXtremely pleased with.
The dedicated “propulsion room” is another of my most favorite design decisions as it similarly provides open and easy access to Mr. Gee and all his components, ….. as well as the Nogva gearbox, coupling and Tides Marine dripless prop shaft seal. I am able to stand, sit or kneel on the grated composite flooring on all sides and with a full meter of width all around and each grate can be easily lifted out of the way to provide access underneath if needed. Having a dedicated engine room with nothing but the engine inside keeps everything inside easy to see and work on, easy to keep well ventilated and all the other components typically found in engine rooms such as fuel filters, batteries and system components are kept OUT of this environments heat and vibration. More examples of how well the open and accessible systems design is one of our favorite features.
Layout (cabin locations, balance living vs functional, up/down)
The overall interior layout also makes it way to the top of our favorite aspects of live aboard Möbius. For us it has the Goldilocks balance between amount of living space vs functional systems space and our decision to have a very large forepeak up front and then an even larger engine room/workshop space in the rear has resulted in a great layout as well as keeping these spaces completely separate with their own dedicated access so you never need to go through a living space area to get to something in the forepeak or engine room or workshop. The vertical layout has also worked out eXtremely well for us with each cabin a few steps below the SuperSalon and the SkyBridge up above. One of the most useful features of our layout is having an enormous “Basement” area below the floor of the SuperSalon. We designed this to be 1.2m/ 4ft high such that you can easily move around by bending over and not hit your head on anything and then sit or kneel to access any of the equipment mounted on intermediate floor to ceiling walls or access any of the many storage bins and shelves in the Basement. The stairs leading down into the SuperSalon from the Aft Deck on the Left and then around to the stairs down into the Ships Office and Guest cabin on the Right provide excellent access between all these areas. Very difficult to photograph but hopefully this pano shot of the SuperSalon will help convey why we like this layout with the 360 degrees of glass so much.
SkyBridge
We knew we wanted a Flybridge overtop of the main Salon or House so this was part of the design from the beginning but I don’t think either of us appreciated just how much we would enjoy this feature and how much time we would spend up here both when at anchor and underway. Part of what makes this space work so well is our decision to put the Upper Helm at the Aft end of the SkyBridge. As we’ve done in several areas of the boat we have created an initial prototype for the seating in this SkyBridge Lounge area by using patio furniture which we rearrange from time to time to figure out what will work best longer term. So far this L shaped layout has worked out best. There are great sight lines when sitting in the Helm chair just outside this photo on the far Left and yet still takes full advantage of the height for sight lines through the 360 degrees of windows that surround this entire space. The Bow and the side rub rails are all fully visible from the Helm chair. The roof overtop of the outdoor galley down on the Aft Deck does prevent a direct view of the transom but otherwise the sight lines Aft are great and we have a camera that displays a birds eye view of the transom on the Helm displays if needed when backing into a dock.
The Helm down in the SuperSalon duplicates the Upper SkyBridge Helm. But unless the weather is very cold or wet we much prefer to run the boat from the SkyBridge with its added height and even better visibility.
At anchor it also makes a great office space and a comfy bed for naps and off watch time as well. So the SkyBridge definitely makes it onto our top favorites list.
Hot Water & Heated Floors
Another example of the advantages of taking a Systems approach is our Domestic Hot Water system or DHW and probably fair to say that the heart of our DHW system that puts his solidly on our top favorites is our decision to install a Kabola diesel fired boiler. Located with all the other system components in the Workshop it is out of the way yet easily accessible. The 75L Kabola boiler is our primary source of DHW as it circulates through one of three heat exchanger circuits in our Calorifier that stores all our hot water as can be seen in this cutaway demo. The second heat exchanger circuit routes hot water from our Gardner engine and so whenever we are running the boat this provides all our hot water instead of the Kabola boiler. The third heat source is a 240V electrical heating element which we can use if the water based heat exchangers should ever fail.
However the one feature of our DHW that truly steals the show in cold weather is mostly invisible and that our Heated Floors. Underneath the vinyl flooring in all the living spaces there are circuits of plastic PEX tubing that circulates hot water and provides a creature comfort in colder climates that is difficult to adequately describe in words. A detailed description of the whole heated floor system can be found HERE in this previous blog post.
As you can read in that more detailed blog post, this is quite a simple system really but does take a bit to get your head around how it works as this is all part of the overall domestic hot water system so that all the water flowing through the floor PEX is coming from the Calorifier in the Basement circulating the same water as distributed to all the sinks and showers on the boat. No valves to adjust or turn on/off it all works by virtue of how this “Open Direct” plumbing design dictates.
Overtop of the PEX tubing and rigid foam, these industrial vinyl floor planks provide a fantastic floor in all weather conditions and are specifically made to work well with heated floors. Critical for our use on a boat, these vinyl floor planks have a simulated wood grain texture molded in which has proven to be completely skid proof even with wet feet and any spills clean up easily. After two years of rigorous use these floors show zero signs of wear or marks which helps keep them on our top favorites list.
There are three independent zones for the two cabins and the SuperSalon and each is controlled by one of these easy to set thermostats which maintain whatever temperature you want.
The manifolds and pumps are mounted down in the Basement up against the Aft bulkhead and yet another example of how easy this whole system is to access.
Battery & Solar Based Electrical System
Yet another systems approach on our top favorites list is our overall Electrical system. It is “battery based” in that all four voltages; 12V + 24V DC and 120V + 240V AC comes from our 1800Ah @ 24V House Battery bank. AC is created via the 5 Victron MultiPlus inverter/chargers and the DC is provided via three DC distribution boxes; Central Main in the Basement plus one in the Forepeak and one in the Workshop for the high amperage circuits there. Solar is our primary source for recharging the house batteries most of the time but when we are underway the two massive 250A x 24V Electrodyne alternators with WakeSpeed 500 regulators provide up to 9KW of power and we also have the option of connecting to shore power whenever we are in a marina. There are eight 320W solar panels that form the roof of our SkyBridge as seen in the photo above and then three more mounted on top of the cantilevered roof over the Outside Galley on the Aft Deck as seen here. And then three more mounted in a hinged frame in front of the SkyBridge. These 14 solar panels add up to just over 4kW of potential power and most days our battery monitors show an actual input of between 1kW during the winter months and up to over 2.5kWh of power during summer hours. Each solar panel has its own MPPT controller which are mounted in the Basement and feed into individual circuit breakers for further control as seen here. Having a dedicated MPPT for each panel reduces the impact of any shading on any panel and helps with the overall performance of our solar system. This screen shot from our Victron VRM display shows a summary for our solar output vs electrical consumption so far in 2023. And this summary of the past 2 days, April 28+29 2023 lets you see how it varies throughout a 24 hour day. We have not been in a marina or connected to shore power in the past four months and the combination of solar and alternator power is keeping our batteries 100% charged every day and so easily makes it onto our favorites list!
Handholds Everywhere for Everyone
Safety was another of the four design principles we had and one example that has proven to be a big favorite is the way we were able to ensure that there were super solid hand holds for EVERY person onboard from children to adults.
On the exterior the handholds are all 30mm diameter thick walled AL pipe such as these on the aft end of the house roof near the Aft Deck. These pipe handholds also make for eXcellent strong points for fastening things with Dyneme and other lines. Perhaps one of the most important spots for handholds is along the side decks when you are moving between the Fore and Aft Deck areas. On the left you can see the continuous length of AL pipe that runs along the entire edge of the house roof and then the three rows of Dyneema landlines that Christine rigged between each of the sturdy vertical AL stanchion pipes. The top lifeline is 1 meter above the deck so hits most adults about waist height which ensures that even if you were to be thrown against these you would be stopped and not flipped over top. Up at the Bow there is a very solid set of AL pipe railings that wrap all the way around and make this area extremely safe and fun spot to be for dolphin watching or just dangling your feet overboard and taking in the scenery at anchor or underway. At the far end of the Aft Deck there are solid AL pipe railings for the corner of the deck before the stairs going down to the Swim Step and then a solid AL pipe railing on the other side of the steps. In the Engine Room, Mr. Gee has a full set of AL pipe railings wrapped around him to ensure you can’t be tipped over onto him in rough seas and these have worked out very well to also provide good support as you are leaned over working on various parts. On the interior of the boat one of our favorite esthetic features of the gorgeous Rosewood cabinetry is the design we came up with to incorporate built in hand holds to the design that are located on all the cabinets in all the cabins and SuperSalon. This example is on the corner of the Galley cabinet across from where the fridges are located. These solid Rosewood edges wrap around the whole boat to form what we call our “Blue Horizon Line” and their key feature is that they have a deep groove that is at about waist height where your fingers naturally slip in to provide an eXtremely secure hand hold. We have had our grandchildren onboard several times now and these have worked out as designed to be at Goldilocks height and size for their fingers too.
Interior Materials:
Possibly saving the best for last, something that brings us joy every day is the choice of interior materials we made.
The Rosewood we chose for all the cabinetry really steals the show and this shot of the Galley cabinets will give you some idea. We were very fortunate that Naval Yachts happened to have their very best cabinetmakers throughout the entire build and they were a joy to work together with to produce details such as how all the grain is bookmatched such that it literally flows from one piece to the next. This was made possible because after months of searching we were able to purchase an entire flitch of Brazilian Rosewood that had been flat cut from the same log. As each slice comes off they stack these in order and therefore the grain of each slice follows the next. The other key was finding a matching stack of solid Rosewood that would be used to build the frames and every edge of every panel. NO veneer edging allowed! Unlike more typical construction, all plywood edges had these T shaped pieces of solid Rosewood glued in place and then the veneer was applied AFTER so that it overlapped the solid wood edging. What this does is ensure that there are no glue joints exposed and they become invisible as they gradually transition from veneer to solid. When these panels would be used for a corner of a cabinet, a thick piece of solid Rosewood was glued glued on and then this solid edge was rounded over in a shaper to create a large radius corner The Rosewood was more than 11X the cost of any other hardwood so to help stretch the prized solid pieces it was sometimes possible to glue on a piece of cheaper hardwood like this and then round the Rosewood for the corner. For the very large radius corners, strips of solid Rosewood were edge glued up and then radiused like this. Or like this. When combined with the Turquoise Turkish marble and the inset Blue Horizon line strips, the end result was well worth the extra time and expense to build. We carried the same combination of materials throughout both cabins, Salon and Galley and I hope these few photos help you see why this puts a smile on our faces every day. There is a LOT more that we like about our dear Möbius and she has definitely lived up to being “Project Goldilocks” by being just right, just for us but the above items hit upon most of our top favorite features and I hope this review was worthwhile. Of course there is always the other end of the spectrum and so in the next blog post I will follow up by reviewing things that have not worked out as well or are things we want to change so do stay tuned for that.
It was a busy week for both Christine and me but nothing too blogworthy so this week’s Möbius update will be short for a change.
I just returned to Möbius last night after spending most of the week in England. This was my first trip for 2022 and a nice change of pace for me. It has proven to take a LOT of time, energy and $$ to get parts shipped from England to us here in Turkey so I decided it was best to go pick up the new parts I needed for Mr. Gee in person from Gardner Marine Diesel and bring them back with me. To be honest, I will take just about any reason to make a trip to GMD and see Michael, James and David there so it was an easy decision. To make it even more compelling, Pegasus Airlines has very cheap flights twice a week between Antalya and London so my entire trip would cost less than the customs duties to ship the parts to me and would take at least a month, sometimes two to get here. The icing on the cake for me was the chance to get in a visit with a very good friend Robin and his wonderful wife Jayne. Robin and I first met when we were both fairly new to Autodesk back in about 1990 and have continue to grow our friendship over all those years. My thanks to Robin and Jayne for opening their home and hearts in welcoming me to stay with them and we had a delightful three days hanging out and catching up.
My outbound flight was very early in the morning so we decided to rent a car and spend the night in a fun little hotel not far from the airport and enjoyed a nice “date night” out at a great little family restaurant right across from the hotel. Christine was then able to do some shopping for groceries and other items that are much more available at the larger stores and malls in Antalya and then drive back to our small town of Finike so it all worked out very well..
XPM78-02 Vanguard
We also took advantage of being back in Antalya to stop by the Free Zone and Naval Yachts to see the progress on the several new builds they have underway. XPM78-02 mv Vanguard is now looking very much like a boat now that the superstructure for the Pilot House is in place. The other build is for the larger XPM85-01 which is in the early stages of the ‘hotworks’ and after a long wait due to supply chain and other issues, all the aluminium plates and parts have been delivered. These boats are built upside down in this first stage until all the hull plating is welded in place and then the hull is flipped right way up. The upside down deck plates are first put together in the steel framework bolted to the floor and then frames and bulkheads are tacked in place. Meanwhile, over on Vanguard, Uğur and Nihat, who did most of the AL work on Möbius are now busy welding the hundreds of Al pieces in place. You can see some of the cut and rolled plates for the keels setting on the floor to the Left. XPM78-02 is based on the same design as Möbius but will have twin JD engines as you can see from the dual prop tunnels in these two photos. The aft deck will be slightly larger and the Owners have decided to build some of the furniture into the boat such as this L-shaped dining area. Large window behind it, WT door into the SuperSalon in the middle and stairs up to the SkyBridge on the Right.
Here is the view from inside the SuperSalon looking back out onto the Aft Deck.
Going up those stairs the SkyBridge is starting to take shape and more built in furniture with an other L-shaped settee at the Aft end. Peering down from the very Aft end of the FlyBridge and roof overtop of the Aft Deck you can see the same arrangement as on Möbius with the doghouse for walking into the Engine Room on the Left and matching winding stairs on both sides. Looking up and aft lets you see another view of the upside down XPM85. Back down to Deck level on Vanguard, you can see another owner driven change with the addition of these bulwarks running most of the length of the side decks.
Bulwarks run all the way up to and around the Anchor Deck and bow. Up at the Bow the “sidewinder” anchor setup is the same as we designed for Möbius along with the Samson Post in the center and nose cone in the very front. This setup has proven to work out eXtremely well on Möbius so has been replicated here on hull #2. You can see how Dennis has nicely designed the Bow and anchoring arrangements to now include the wrap around bulwarks.
XPM78-01 Möbius
Lest we should forget the Mighty Möbius, I will leave you with THIS LINK to a series of photos that Captain Christine put together while I was off in Gardner Land in the UK this past week. Christine went through some of our archives of thousands of photos over the past 6 months or so and put the ones she liked into this album. So if you’ve been Jonesing to see less of the Engine Room and all the detailed technical shots that I post and more of the interior and exterior of Möbius, click the link above and enjoy your tour through this collection. Thanks for taking time to join us here again this week and hope you’ll be back again next Sunday for the latest weekly update on what’s been going on in Möbius.World.
Special thanks to all of you who have been contributing your questions and comments in the “Join the Discussion” box below and please keep them coming!
We don’t use SCEM as filters per se, we use them to keep us on track, keep our priorities straight, by reminding us of what our fundamental values are for this boat. When doing our due diligence and research on some potential piece of equipment It is all too easy to get attracted or distracted by things like cool features or just the sheer number of choices and so as we go through our decision making we are constantly circling back through SCEM to make sure these fundamental requirements are being met.
This week in this Part 2 of our decision making process, I will do my best to summarize the more specific criteria we use to ultimately make our final decisions upon. I will cover this as a series of the following questions that we ask and answer to our satisfaction at least, as we evaluate each bit of kit and then use these to make our call.
What problem is this item attempting to solve?
Is the problem/item a want or a need?
Consequences of adding this item? Domino effect?
Does it pass the Goldilocks test?
New vs Tried & True?
What problem is this item attempting to solve?
Might sound like a silly question at first but it is surprising how often answering this question provides the most help in in our evaluation of a design decision or of a given piece of equipment. Let me use our decision of what battery type to use for our House Battery Bank to illustrate but one example of how valuable this question was.
To put this question into context, keep in mind that Möbius is a completely Battery Based Boat, meaning that ALL of our onboard electrical power comes from our House Battery Bank and therefore this is one of THE most critical systems on the boat and one that in some cases our lives can depend upon. For an XPM or any true eXpedition boat that is going to be able to carry us safely and comfortably to locations across the full spectrum of eXtremes of climate and remoteness, we need to be as self sufficient as possible and so our onboard electrical power rates right up there alongside diesel fuel and fresh (potable) water as a critical requirement. An XPM type boat is designed to spend the majority of its time at anchor or at sea, in our case often for months at a time, so in all our design and equipment decisions, we assume that we will have no shore based resources such as shore power, stores, shipping, airports, etc..
Finally, for a bit more context, let me add that we have also chosen to not have an independent generator onboard so ALL of our four voltages, 12 & 24 Volt DC and 120 & 230 Volt AC, come from our House Battery Bank. Most of the time we keep our batteries charged via our 4.48kW array of 14 320W Solar Panels and when underway we have 12-14kW available from the two eXtremely robust 250A @ 28V Electrodyne alternators which Mr. Gee keeps spinning. One of the very first decisions we needed to make to chose our batteries was what type or chemistry of batteries would be the Goldilocks just right, just for us House Batteries? I’m not going to go over this in any detail here but these are the five battery types we had to chose from:
FLA; Flooded Lead Acid
AGM: Absorbed Glass Matt
GEL:
Carbon Foam
Lithium
Many of you and others we talked to, thought for sure that the choice was obvious; go with Lithium and we did consider them, and all the other types, very thoroughly. But it was that question of “What problem is this trying to solve” that made it clear that Lithium was not the best choice for us and that’s the story I’d like to elaborate on here a bit.
Our battery decision making started at the very beginning of our design process, around 2016, and in some ways we designed and built the boat around the House Batteries. For the first few years, we thought we would go with GEL based OPzV batteries such as this one.
These OPxV type batteries are eXtremely robust and often referred to as “traction batteries” as they are used in things like all electric forklifts in warehouses so they had good cycle life and good resistance to sulfation and other features that wold make them a good choice for Möbius.
During this time we were reading more and more about Lithium batteries and we were seeing more and more people who were choosing to go with them so we also spent a good bit of time researching the various types and makes of Lithium, primarily LiFePO4 or Lithium Iron. This relatively new type of battery was said to have a lot of amazing features with the top ones being longer lasting (more cycle life), ability to accept much higher charging rates thus take less time to charge, but perhaps the biggest feature was their much higher energy density. This means that you get much more usable Watts from the same amount of space and weight compared to what you would get from other battery types. Said another way, you could get the same amount of energy out of a much smaller size and lighter battery bank.
As the months and years went by, these claims were validated more and more and we saw the steady increase of Lithium Iron being the batteries of choice for more and more boats so it seemed like the choice was clear right? However when we applied our criteria and use case and asked the “What problem is Lithium trying to solve?” question, we realized that we didn’t have the same “problems” as most of these other boats such as size and weight of our House Batteries.
My earlier comment that we had designed the boat around our House Battery Bank is not that far off as we had designed the hull to take maximum advantage of the characteristics of our original consideration of OPzV batteries which were very large and very heavy. Each OPzV 2/4V cell measured 215mm/8.5” Wide x 277mm/10.9” Deep x 855mm/33.6” High and weighed 110kg/242lbs each, and we needed 24 of these! As we often do, we turned this “bug” into a feature and built four large battery compartments into the framing of the bottom of the hull such that each compartment straddled the 25mm thick x 350mm high keel bar running down the centerline of the hull. By positioning these battery compartments on the very bottom and center of the hull, we effectively turned the lead in our batteries into a proxy for some of the lead ballast we needed. This is a photo from last year of one of our four battery compartments.
The point here if you are following along with me is that for the use case and design of an XPM, the “problem” that Lithium batteries would solve with their high energy density for a given weight and size just wasn’t a problem we had; we had the room and we wanted the weight. So the search for our Goldilocks batteries continued.
For awhile we continued to think that OPzV Gel batteries were the best fit for us, however, just as we had been following the developments of Lithium batteries we had also been tracking the growing use of Carbon Foam type batteries from FireFly. They ticked all the boxes on our list of criteria, most notably these were proving to be eXtremely robust and several attempts by test labs trying to purposely destroy these batteries failed and they proved to be almost indestructible which is a huge factor for us and our use case. These Carbon Foam batteries are also able to work and charge in much lower temperatures such as those we expect to have when we are in polar regions of the world and they are one of the only battery types that don’t suffer from sulfation. and are happy, even recommended, to stay at Partial State of Charge for long periods of time which would normally be the death of most other batteries.
Near the end I found real world installations of these batteries, some of which had been in place for more than ten years and so just before placing this large order of batterie we changed and ordered 24 of these 4V L15+ size Micro Carbon Foam batteries which now make up our 43.2kW House Bank (1800Ah @ 24V) made by FireFly and they have been working flawlessly for the past six months.
Let me be clear that I am NOT saying that Lithium batteries are not a great choice for many boats, nor am I saying that Carbon Foam batteries are “the best”, I am just hoping to explain how and why we made our decision to go with Carbon Foam and why they are the Goldilocks just right, just for us choice. All thanks in part to the question we regularly ask near the beginning of our decision making process; What problem is this trying to solve?
Is the problem/item a want or a need?
We often put each item we are trying to decide on into either the Need to Have or Wish/Want to Have category. Pretty self explanatory I think, Need to Have are items that we feel are mandatory must haves in order for us to feel confident in going to sea and living full time aboard Möbius. Examples for us include things like;
our high output watermaker,
Furuno Radar and other navigation equipment,
eXtremely high amounts of acoustic & audio insulation,
comfortable Helm Chairs,
that little FLIR One thermal camera I used to find the overheated wiring a few weeks ago,
great HVAC systems
Global communication capability (right now via our Iridium GO)
and items like this.
The Want/Wish to Have category can be subdivided into groups such as;
buy as soon as the budget allows
later when it is ready for real world use (ours)
nice to have, perhaps a gift to ourselves or each other
Current examples on our Wish/Want list includes things like:
second Furuno Radar with NXT technology,
forward facing sonar when it is has been in more mainstream use and is robust enough for our use case
active stabilization, most likely Magnus Effect type
kite sail with autopilot to add to our propulsion and reduce fuel usage
Portland Pudgy, Christine’s long time wish for a small, light sailing dingy
affordable high speed internet such as that being promised by 5G and satellite based systems being developed.
We also have a third category worth mentioning which is the Don’t Want Onboard category which is sometimes the best choice. Items on this list would include things like;
anything that requires propane (too much of a pain to fill around the world)
anything that requires gasoline (too short a shelf life these days)
Generator
Guns/weapons
Consequences of adding this item?
As a good friend and fellow world sailor likes to say “Everything needs” and so we spend time trying to imagine what the needs and other consequences will be if we add this bit of kit to Möbius. Our primary prioritization of Maintenance, lack thereof, would factor into this for example and hence decisions such as;
no paint/wood/SS on the exterior,
being single fuel boat with no propane or gasoline,
no generator
but it could also be other consequences of adding this item to our boat. An XPM is complex by virtue of needing to be so self contained and as we often say Möbius is like a floating village in that we have to look after making all our own water, all our own energy, dealing with all our own waste and so on, but we do strive to apply the KISS or Keep It Simple & Safe philosophy to all our decisions by finding the simplest solution possible. Examples of this would include:
manual roll attenuation with our fully mechanical/manual Paravane A-Frames
manual Tender Davit system vs hydraulic
Gardner engine (no turbo, no electrics, low revs, etc.)
Domino Effect?
The Domino Effect is perhaps a branch of the consideration of the Consequences of any decision as I just outlined above and is when the result of a decision has follow on effects to other systems on that boat. This can work both ways; sometimes these dominos are positive ones and in other cases they are negative or undesirable consequences. For example, installing the eXtreme amount of EPDM and acoustic insulation throughout the boat has a domino effect;
stabilizes the interior temperatures and makes them more temperate in both very hot and very cold climates
this reduces the energy required to cool/heat the boat
this allows us to install smaller capacity and less expensive HVAC systems such as Air Conditioning and heating
this lowers the demand on our House Batteries and HVAC systems so they run with less loads and last longer
An example of when the Domino Effect can work the opposite direction might be the option we considered of installing fin type active stabilizers. These work extremely well to reduce the roll in many conditions when on passages but they would also introduce a Domino Effect of consequences that took them out of the running for us, such as;
their protrusion from the side of the hull reduces the safety factor when in areas with uncharted rocks, coral heads and the inevitable groundings on these.
not suitable when ice is present in polar waters
unlikely but possible if a fin is hit hard enough to create an underwater breach of the hull
are extremely complex and often top the lists of most maintenance problems we read from other global passage makers.
most require a significant hydraulic system to operate which adds yet another whole system onboard to maintain and repair.
I might add that having gone through this Domino Effect as we considered active fin stabilization, it also helped us see that we could find a different type of active stabilization if we should ever want that, and one that eliminates most of the dominos I listed above. This would be stabilizers that use the Magnus Effect which is offered by several different manufacturers now.
Does it pass the Goldilocks test?
We essentially answer this question by virtue of having gone through all the questions and priorities I’ve already listed. Because we have highly personalized our overarching principles of SCEM and articulated much more detailed specifics of our use case, our decision making helps us ensure that we are making choices and decisions that are by definition, Goldilocks, just right, just for us.
However, this is such an important factor for us that we do keep coming back to to this “Goldilocks Test” to make sure we are avoiding the tendency to “go with the flow” of following what others are doing or “the way its always been done” and are staying true to ourselves and our preferences. I will site a more “meta” example here which is our decision in the design phase to “upsize” the length of the boat from the 18-20m / 60-65 ft that we initially imagined and then at the same time “downsize” the interior to have just 2 cabins and 2 heads.
Our decision to extend the length to 24m/78ft was driven two factors; simple physics that hull speed is a factor of Length on the Waterline and our discovery that contrary to popular opinion there is not very many restrictions on boats that are over 20 meters whereas there are some very significant changes to the rules governing ships that are over 24 meters. With our prioritization of efficiency, we pushed the length to just under 24 meters. With our infrequent use of marinas the increased docking fees do not affect us very much. Furthermore, with more and more catamarans being purchased, many marinas are changing their dock rates to be calculated based on overall area of each boat, LOA x Beam and so our slender 5m Beam reduces our overall area and we are often cheaper or about the same as much shorter but wider boats.
Our decisions to “downsize” the interior and thus reduce maintenance and costs was based on the fact that 99% of the time Christine and I are the only two people living onboard so we wanted to make the interior fit us and our needs. Our Master Cabin is very spacious and luxurious for us. Our Guest Cabin works very well when we do have guests onboard but most of the time it is a very purposefully designed Office for Christine Kling, the Captain’s nom de plume when she is working on her next book and running her growing book business. Our SuperSalon is indeed living up to that name the more we live in it. And my very full size Workshop and Engine Room is that of my dreams.
There are many other examples of how the Goldilocks Test has driven our decisions such as;
Manual Paravane system and Tender Davit that is KISS and as former sailors handling lines, winches and clutches is second hand.
Though we designed and built the cabinets, electrical and plumbing for them, we chose not to install either a Dryer or a Dishwasher as we are just not fans of either one and prefer washing and drying by hand.
I could give countless more examples of how we have applied the Goldilocks Test to almost every decision we have made during the design and the building process but I think you get the idea. We have now been living aboard Möbius since she first launched in February and we are finding that our continuous use of this Goldilocks Test has worked eXtremely well for us in designing and building Möbius and we can and do recommend it highly for almost all decisions and choices you make.
New vs Tried & True?
Christine and I are self described nerds and geeks so we have a great fondness for technology that is on that well named “bleeding edge” and we have a full compliment of devices to show for it. However, when it comes to equipment for Möbius, and especially all of it that is on that Must Have list, it must be remembered all those decisions must be made within the context that Möbius is an XPM type boat that is designed and built to live up to that acronym for eXtreme eXploration Passage Maker. So when it comes to deciding on equipment, materials, construction and design of these items, they must, all be Tried & True. To us this means equipment that has been in regular use on boats, ideally with similar use cases as ours, for several years and has stood that test of time.
Some examples of this for us include:
we delayed our decision to go with FireFly Carbon Foam batteries until after we had been able to find enough examples of these batteries being installed in other people’s boats in large numbers for many years.
We chose to go with all Furuno for navigation because it is so widely used by commercial boats in fishing fleets, government agencies and the like and hence this equipment is designed and built for continuous 24/7 use in some eXtremely harsh conditions. They also have an excellent reputation for their continued support of even their oldest equipment.
Our decision to go with a Gardner 6LXB engine that is still one of the most efficient diesel engines ever produced and is still in use in thousands of commercial boats worldwide. It is also perhaps one of the best examples of the KISS approach to design and engineering which adds to how well it passes the Tried & True test.
individual MPPT controllers for each of our 14 solar panels as this has been well proven to be the most efficient combination for both overall efficiency, least affected by shading and highest redundancy.
Let me end with a final example of the value of taking this Tried & True test for mission critical ships and equipment from no less than the US Navy! A recent article caught my eye a few weeks ago where even the us Navy has learned the folly of installing untested equipment on their ships. This link to the article USS Gerald R. Ford Problems: The Navy Admits Its Big Mistake (popularmechanics.com) provides a brief but telling story. as outlined in that article the Chief of Naval Operations, Mike Gilday, says the U.S. Navy built the aircraft carrier USS Ford with too many new technologies. such that now, the Ford is several years behind in its life cycle because of problems with many of those new technologies.
The last of the Ford’s four advanced weapon elevators, the most glaring example of the ship’s tech gone wrong, should enter service later this year.
When the Navy first built the Ford, it incorporated nearly two dozen new technologies, some of which are still giving the service headaches 4 years after the ship entered the fleet. Those delays meant the Navy only commissioned the Ford in 2017, despite laying it down in 2009. Even then, problems lingered, especially with the electromagnetic aircraft launch system (EMALS) and the advanced weapon elevators (AWEs).
The ship’s first full deployment, originally scheduled for 2018, is now set for 2022.
I think this unfortunate real world example does help to make the point that for XPM types of boats with use cases to match, all the “mission critical” equipment onboard MUST have passed the Tried & True test.
Bubble Bubble, Toil & Trouble!
Leaving you with the latest bit of kit that Captain Christine just approved and installed onboard, a fully manual sparkling water maker! Especially in these hot summer months, Christine particularly enjoys her cold sparkling water and I do too but we don’t like having to buy it in cases of plastic bottles. We have our watermaker for similar reasons for our regular drinking water. Initial tests have elicited the same smile you see here so this item has now passed the all important Captain’s Test and has been welcomed aboard. Thanks so much for making it this far if you have and I do hope that this slightly different format and content is of interest and value to most of you. Let me know either way with your comments in the “Join the Discussion” box below and I’ll be back with more for you same time next week.
Another eXtremely busy week for Christine and I as we continue to work our way through all the rigors of getting Möbius ship shape and ready to head out to sea.
I’m sure some of you must be wondering why such a seemingly simple step is taking so long? But many of you who have ever moved into a brand new home or new RV or new boat, especially custom built ones, will be able to relate to the seemingly endless list of jobs big and small that need to be looked after before your new “home” feels like it is yours and that you have worked through all the “little” things that don’t work right and all the improvements or installation of additional things be that putting in the new lawn in your newly built home.
I’ve read that many others who have gone through this process say that to get to the point where you can simply enjoy your new home and not be constantly working on it, takes about a year. From what experience I have had so far with both boats and homes that sounds about right to me. Hence Christine and I remind each other that this is a marathon not a sprint AND we enjoy* the whole process of making Möbius our full time super comfy home.
* Well most of the time anyway!
While we are seemingly busy non-stop, there isn’t much to see during this process that suits a Show & Tell so this will be a relatively short blog update (lucky you!) but let’s jump right on and catch you up on what’s been happening aboard the Good Ship Möbius this past week of May 24-30, 2021.
Wonderful Days in the Neighborhood
We continue to have stellar “Spring” weather here in Antalya though it is really more like an early arrival of summer.
Daily highs are typically in the low 30’s C / 90-95F and usually with a nice breeze to make it all very pleasant. Almost always clear blue skies, complete with the exclamation point of jet trails. This is our immediate neighborhood here at Antalya Setur Marina.
Things have changed a bit here as our big Blue powerboat neighbor to the right in this photo finished all their jobs, launched and headed out for sea on Wednesday.
So we now have a lovely large empty space next to us and our views of the Med and the Coast Guard station are much improved when we are out having our nightly sundowner wine on the Foredeck each evening.
And we continue to enjoy our life here propped up “on the hard” though we would of course much prefer to be floating on the water and hope to be doing so by end of June at the latest.
As you will soon see, Mr. Gee is not the only one “moving up in the world” as we have had some significant new neighbors move in next door in the form of these three little guys from the Turkish Navy. As you may have noticed in some of the aerial and satellite photos I’ve put in some recent posts, the area behind the big beautiful breakwater here on the far Western end of the Antalya coastline, contains four very different harbours within and I’ve marked up this satellite photo to help visualize.
Infant Mortality
Not the most pleasant terminology but this is an all too apt description of what commonly happens during the initial few months after moving into a new home/boat/RV etc. which is when brand new equipment fails to work. We have had our share of these already and likely more to follow in the coming months.
This is one of the latest “infants” to be DOA, our fabulous new Bosch washing machine. After going for many years without any washing machine Christine had been really looking forward to testing out this fancy (to us) new washing machine that she had so thoroughly researched and chosen. Alas, it made it part way through the first wash cycle and stopped working. As the saying goes “the lights were on but no one was home” as the big LCD panel lit up with all the controls, but none of them or the selection dial responded to her input.
Of course everything is under warrantee and Bosh is a very popular brand here in Turkey but it still took them three different calls and over three weeks to end up replacing all 3 internal circuit boards! Even though this was MUCH sooner than expected, we know that it is always when not if equipment and appliances will need to be serviced so we have designed the boat with accessibility as a key component and so it was a relatively quick task to help these two Bosch servicemen to remove the washing machine from its cabinet, set it on the floor and allow them to open it all up and replace those 3 circuit boards.
Good news is that IT WORKED! and Christine has already put it to the test with multiple different loads of laundry and is just beaming at the “upgrade” in her onboard chores.
Electrical System Update
Many of you have been asking about how some of the various systems are performing in their early days as we start to gather more real world data and while still early, here is a preliminary update for you on how our overall electrical system has been working.
This is a very high level graphic I’ve put together to show the overall Electrical System on Möbius. Given our use case of being in very remote locations and on anchor over 95% of the time, we are a fully “battery based boat” which in short means that we have no generator or other source of external electrical power input and so ALL our electrical power comes from our 1800Ah @ 24V 43.2kW House Battery Bank as you can see in the illustration above.
To be clear, we DO have the option of connecting to Shore Power with plug ins for these at both the Bow and Stern, however we are so rarely have access to Shore Power we consider this just an emergency backup if we were to need to go to a marina to work on components within the battery based system.
Even when we DO have ready access to Shore Power, such as we do now up on the hard here in Setur Marina, we chose to still NOT connect to the Marina’s Shore Power grid. This is partly because electricity here at this marina is very pricey, but more so because we simply don’t need it and also want to be more fully testing out our overall electrical system in its normal state of running entirely off the House Battery Bank and charging those with “just” our large 4.5kW solar array consisting of fourteen 320 Watt panels, each with their own Victron 100/20 MPPT controller.
This is a screenshot of the Victron Connect app on my phone a few minutes ago (10:30 am Sunday 30 May, 2021) and as you can see the solar panels are having no problem at all bring the House Bank back up to 100% SoC (State of Charge) after running everything on the boat while the sun was down.
Because we are in “test mode” for the first few months we have been maxing out all systems and in the case of our electrical system this means running EVERY electrical device onboard as fully as possible. For example, after we had fully tested the Kabola KB45 diesel boiler for about a week we shut it down and turned on the 230V 1500W electrical heating element in the Calorifier (water heater tank) which is a very big consumer. Other electrical equipment on all four voltages (12V + 24V DC and 120V + 230V AC) we are using daily and as frequently as possible to build up the data set for maximum use includes such electrical consumers as:
Bosh 4 burner induction “hob” cooktop with extraction fan running throughout
Bosch Smart Oven that combines convection/grill/microwave
Kenyon 230V BBQ grill
250L/hr watermaker run about ever 4-6 days
two 130L 24V refrigerators
two 70L 24V freezers
230V electric kettle & 230V espresso machine
Bosh washing machine (now that it is working)
At least 4 computers and at least four large monitors which are rarely turned off
50” TV for nightly “dinner and a movie” onboard streaming content from YouTube, Netflix, Apple TV, etc..
a long list of internet based equipment such as routers, bridges, cellular & WiFi extenders, etc..
VacuFlush toilets w/ Bidets
an eXtremely extensive Maretron monitoring and control system and an equally extensive NMEA 2000/N2K network
the usual compliment you would expect from two nautical nerds of 3 smartphones, 4 smart home (Amazon/Google/Apple) devices all of which need to be regularly charged or plugged in.
and the usual assortment of regular living items such as lights, music, TV, sound systems, fans, etc.
With so many other systems needing our attention, the only two significant systems we have not yet tested and run extensively are the 3 zone in-floor heating system and the AC/heating system via the Webasto V50 Chiller and the four Webasto Air Handlers (5400 BTU overall) in the three cabins. We will get to those as soon as we can and all the more so as the daily temperatures start to rise up for summer into the mid 30 to 40C range typical of Antalya summers.
For the more technically minded, here is a bit larger history view of what’s been happening since we launched back on 20 Feb. 2021.
We have had a LOT of different scenarios onboard since launch and during the commissioning of all the electrical components so we have twice run the batteries down below 20% SoC and also had no battery connections several times and hence some of the very eXtreme numbers you see here. In total we have used 21,808 Amp hours with an average 24hr discharge of 417Ah and yet only required 5 total charge cycles.
During the past 3+ months since launching, we have had 230V shore power connected for about 3-4 days to test out the chargers in our 5 Victron MultiPlus Inverter/Chargers but otherwise our only source of “external” power is from the 14 solar panels. We are therefore eXtremely happy with these preliminary results and I will publish more and more such real world data as we collect it and once we are underway and back to our more typical use cases.
Mr. Gee Gets High!
Interestingly, the one bit of kit that seems to get the most attention from so many of you is our beloved Gardner 6LXB engine, which as most of you know by now, we affectionately refer to as Mr. Gee.
Unfortunately and uncharacteristically of any Gardner, Mr. Gee has a problem. He suddenly lost oil pressure on the first sea trial last month, falling from his usual 38 PSI down to about 20 PSI which is definately NOT a good thing! While I have a pretty good idea of the source of this problem, I won’t know for sure until I can do an eXtensive tear down that involves removing the huge cast AL oil pan so I can inspect the crankshaft, oil pump and bottom end bearings.
All a very straightforward BUT to get at these bottom end components I have to lift Mr. Gee about 1 meter up out of his normal home resting solidly on his 25mm thick engine beds and that is taking some time. I also need to remove both of the heads so I can check out the pistons and valves and this will also put Mr. Gee on a serious weight reduction program making the job of raising him up one meter a bit easier. As I remove these various bits and bobs I put them out on one of my workbenches in the Workshop right outside of the ER, which now has the appropriate dual meaning of Engine Room and Emergency Room! Running through the dismantling process quickly for you, off come the valve rockers, pushrods and cylinder head bolts. Off comes one of the cast iron cylinder heads which weigh in at a svelte 65kg/145lb. (ask me how I know?!) This is what Mr. Gee looks like when he goes “topless”!
All looks good so far as I confirm that there has not been any contact between the valves and the piston tops. Whew! Workbench continues to fill up even though I’ve already moved all the intake and exhaust manifolds elsewhere. Down to a mere shadow of his former self, Mr. Gee is all ready to move UP in life. Or at least 1 meter up inside the ER.
I carry a 2 ton hydraulic hoist as quite reasonably I would argue EVERY serious XPM or eXpedition/eXploration boat should and in particular mine is a modular hoist which then also gives me these eXtremely strong cross members to span the overhead ER hatch (previously removed) frame and provide the overhead “sky hooks” aka attachment points for the two chain hoists that I also carry. (of course!) I’m a big fan of synthetic rope, Dyneema or AmSteel in particular as it is much stronger than the SS wire of the same size and MUCH easier to handle. In addition to using Dyneema for all our Lifelines, Davit and Paravane rigging, etc. I also us this for lifting and hoisting eXtreme loads and have used this throughout the entire rebuilding of Mr. Gee. (he likes that the Dyneema is very gentle on his “skin”)
In this situation I am using multiple loops of Dyneema to hang the chain hoist in the foreground as well as wraps around the front and rear ends of Mr. Gee where the hoist hooks will attach to him. My plan is to leave the Nogva CPP gearbox in place and then take the weight of Mr. Gee every so slightly so I can then slide him forward with his feet still resting on the AL Engine Beds. To do so I’ve removed all the bolts fastening the four engine mounts to the beds and then positioned the two chain hoists forward of where they would be vertically centered so that as I lift him up, Mr. Gee will be pulled forward and come away from the Nogva case.
At least that’s my theory and I’m sticking to it! Worked just as planned and if you look closely you can see that Mr. Gee’s silver AL flywheel housing has slid about 50mm/2” forward and now separated from the Burgundy Nogva gearbox. Now it was a simple matter of alternating between lifting with the front and the rear chain hoists to until I had Mr. Gee up about 1 meter above the engine beds and with plenty of space for me to get underneath and remove the oil pan, crankshaft and piston/connecting rod assemblies. With Mr. Gee now floating right where I need him, I built a super solid cross member using more of the rectangular steel components from my hydraulic hoist and then built up a support platform out of solid wood blocks so I could lower him down for stability and safety while I did the first part of the disassembly which involves removing the two halves of the flywheel housing, rear motor mounts, and the massive flywheel itself.
And YES! I have also put four more sets of Dyneema loops, one at each of Mr. Gee’s corners, to add a backup safety system in the unlikely event that any of the main supports should break or fail. Here is the view as of today looking down from on deck through the ER hatch opening. Blue lighting is due to the large blue plastic tarp I have setup on deck in the unlikely event we should get any rain and to keep the marina dust out.
Sadly, I must leave many of you with your questions, and mine too, still unanswered as to just what has caused that drop in oil pressure and just what I’m going to need to get Mr. Gee back to thrumming away endlessly and effortlessly in his comfy ER home.
You can rest assured that NO ONE is more anxious to get to the bottom of this than I am and I’m pretty confident that I will be able to share all of that with you in next week progress update Show & Tell.
Sorry to keep you hanging like this and thanks very much for continuing to join us in this latest leg of Project Goldilocks as we get XPM78-01 Möbius ready to head out to sea.
I would also be most appreciative if you could help me feel a bit less like I’m talking in an empty room by adding your questions, comments and suggestions in the “Join the Discussion” box below. I don’t always manage to answer your questions as quickly as I would like but I will continue to do my very best and please do know that I definately read and benefit from every one.
I double checked the calendar and it is indeed just the beginning of May but it sure feels like summer here in Antalya today. We’ve been having fabulous weather all year actually with an eXtremely mild Winter season that saw very little rain and very mild temperatures. But Spring has been off the charts in terns of great temperatures, low humidity and no rain. Today, Sunday May 9th, is a real scorcher and as I sit and type this aboard Möbius at 14:00 the temperature is a toasty 34C / 93F with a little bit of wind and crystal clear skies. No complaints from any of the crew aboard the good ship Möbius, that’s for sure.
While the lack of visual progress to show you continues as we work our way through the final jobs remaining to fully configure and test all the many systems onboard XPM78-01 Möbius, the amount of work required to play this real world version of Whack-A-Mole is relentless and non stop. That combination conspired to prevent me from putting together an update for you last week and I thank all of you who wrote to ask if all was well and thank all of you for your patience. In this Progress Update I’m going to combine the past 2 weeks into this one, so please grab a comfy chair and beverage and join me for a Show & Tell of what’s been happening from April 26th through May 5th, 2021.
All Hands on Deck!
In addition to all the configuration and testing, there is also a long list of those “little jobs” that add up to be quite a large amount of work all together and we knocked off more of these the past 2 weeks as well and here are a few examples.
Here we find Captain Christine, ably abetted by our two four legged crewmembers, Barney (Left) and Ruby, finished whipping the Dyneema lifelines she had previously spliced in place and which are working out eXtremely well. The Rosewood Dinette table came back from being refinished and is once again mounted to the vertically adjustable pedestal with the XY sliders that allow us to move the table 200mm / 8” fore/aft and side to side which enables us to always have the table in its Goldilocks position for any situation. There had been some small depressions on the top surface of the table which while minor, were also very visible and took away from the otherwise superb finish on all the woodwork so the Finishing crew quickly refinished it and as you can see it is now flawless. There are a LOT of valves, circuit breakers, hoses, electrical connections, etc. that number in the hundreds and so labeling everything is a must and makes it easy to know what’s what and how to operate all these systems. These 3 fuel manifolds provide a good example. You may recall a few weeks ago that the two cleats on the Swim Step were upgraded from AL pipe to solid and the heat from welding those in required that the TreadMaster be removed and now it has been replaced. The light Grey TreadMaster is also proving to be as good or better than we had hoped. The top priority is to provide a great non-skid surface in any conditions and the tight sharp diamond pattern of the TreadMaster eXcels in this department and locks even bare wet feet in place everywhere. Second priority is to provide a more bare feet friendly surface especially when in hot sunny climates so that you don’t have to do your “walking over red hot coals” fire dance when you are on deck. While not comparable to the tropics, today’s high temperatures and intense direct overhead sunlight gives us a reasonable test and we are happy with the results.
For a baseline, as of a few minutes ago, 14:30 Sunday May 9th, here is the temperature on the fully shaded Aft Deck area which my trusty IR temperature gun clocked at 32.4C / 90F. And out on the Stbd side decks that have been getting the most direct sun right now, the TreadMaster is at about 50.5C / 122.9F. Definately not cold, but I can stand in place on these decks without too much discomfort and when walking it is quite comfortable. As in life, everything is relative right and compared to our previous boats, with painted on non-skid on both fiberglass and steel decks, this is a HUGE improvement, so we’re happy with these results.
Love Thy Dock Neighbor!
You’ve seen in previous postings that we have some very interesting and varied dock neighbors here in the Antalya Free Zone with over 30 different boat builders producing a wild and wide range of boat sizes and purposes. Most of these boats are in a similar situation as we are, brand new being launched for the first time so that all the in-the-water testing and finishing can be done. Then once finished, they are off to their new home bases scattered around the world so boats are leaving and new ones arriving on almost a daily basis. Here are some recent examples of our recent neighbors:
On our Port side we have this 34m/112ft steel “Phi Phantom”. This is a support boat for a much larger superyacht so this is all function with huge flat decks and even larger bays below with that monster articulated crane to get all the “toys” off/on this boat and the superyacht. They also carry all the fuel, supplies, parts and maintenance crew. These kinds of support boats are often called “over the horizon tenders” as that’s where they are to stay out of sight of the high paying passengers on the superyacht or a “phantom boat” such as this one that is to stay similarly ghost like or invisible to the superyacht it supports. On our Starboard side we have this Bering 77 I showed you a bit in my last posting.
At 77 feet long overall, she is 1 ft shorter than Möbius but otherwise MUCH larger at more than twice our weight, much taller, much wider and quite a bit slower than Möbius (8 kts vs 11) but still a Goldilocks boat for the right owner and use case. Down the dock a few more meters is this little fella who showed up last week and is the basis of my “Love thy neighbor” heading for this section.
Why you ask? Look a little closer at some of her deck hardware ……….. Like here for example. Or zoom in a bit closer to read that red safety lock….. The more you look, the more interesting it gets. For example, when those hatches in front of the two rocket launchers are opened up it reveals a relatively typical set of instruments, controls and a small bench seat for the operator. Most of the time though and during testing, these hatches remain tightly closed and fully waterproof. So how do they operate the boat now and where is the Captain sitting? Inside here! Turns out this is a fully autonomous vessel or unmanned drone and the real “Captain” is actually sitting ……. …… here!
“ULAQ” is the first indigenous armed unmanned surface vessel (AUSV) developed in Turkey. It is being offered by Ares Shipyard and Meteksan Defence Systems to the Turkish Navy and you can read all about this fascinating research project HERE and HERE if you’d like to know more details. Suffice it to say that we treat all our dock mates with great respect and kindness!
Get the Lead Out no IN!
This was one of the more interesting things happening with our Bering 77 dock mates this past week.
Can you guess what they are up to and what’s in all those wood crates up on the dock? Is this a Turkish version of a Swill Alps horn? Nope, just an ingenious way of putting the lead ballast into the stern compartments of the Bering 77. Here is what is inside all those crates, 1000 Kg of 5mm diameter lead balls like this. One scoop at a time the little lead balls are poured into this funnel, run down the long black PVC pipe into the holds in the aft end and are then capped off with an aluminium plate that is bolted down overtop.
Brilliant!
Meet Mogli!
However, hands down, THE most exciting and interesting thing that happened on the docks this past week happened to us and Möbius.
Hmmmm, what do you think that crane truck is doing behind us?
And what is Captain Christine busy with and what are those weird shaped teak blocks on the Aft Deck? Aha! That’s our Tender flying through the air! and about to be lowered onto those Teak chocks on the Aft Deck. Like this……… ……. and this. And she fits like the proverbial glove and just as I had laid out in the 3D models; with the front Stbd fender just able to rub up against the vertical support bar coming up out of the Port Vent box…….. ……… and the Aft Port corner of the fender right up against the doghouse over the stairs from the Swim Platform into the Workshop. And there she is! Our Tender finally setting in her new home and Möbius is now fully equipped. Sinan, our upholstery master made this tight fitting cover out of some waterproof Sunbrella fabric we had brought over from the US.
This shot provides a good perspective of how nicely everything fits and works together on the Aft Deck with the Tender onboard. Plenty of room in the Outside Galley and the entire Stbd side to walk back and forth the whole length of the boat. Here’s what it all looks like viewed looking forward. Next up is fitting all the rigging to raise/lower the Davit Arch and the Tender within it but that should be a relatively straightforward job that can wait for now.
Oh, and we’ve settled on a name for Möbius’ new “baby” and she will be called “Mobli”. A lot of different parts to the story behind this including a reference to Mowgli in Kipling’s Jungle Book as well as being our sense that Mogli is the diminutive version of Möbius.
Welcome to our family Mogli! We can’t wait to start playing with you in the water and showing you the awemazing aquatic world that surrounds us. Hope you enjoyed this combined 2 weeks worth of Show & Tell from all of us here on Team Möbius. We’ll be back with more next week as we inch closer and closer to leaving the Free Zone and returning to our lives sailing the world.
If you want to get from Point A to Point B and each step you take is exactly 1/2 the distance between you and Point B, how many steps will it take you to get there?
Answer?
An infinite number of steps and you will never get all the way there!
However, the most important thing is that forward progress was made again this week, including two very exciting even though it too ended up being one of those half way steps. But half steps are still steps forward so we’ll take every one we can. The commissioning phase continued this week as we power up and test all our many systems and start shaking all the gremlins, both large and small, out into the open so we can deal with them. As you might imagine this often feels like we are playing the marine version of Whack-A-Mole as we get rid of one gremlin and two more pop up. The major systems we are currently bringing up to speed include the Kabola diesel boiler, the Furuno navigation system, Maretron monitoring system, Domestic Hot Water DHW system and the CPP pitch control system, to name but a few. None of this testing and problem solving creates very visual or entertaining content so again this week you get a reprieve from my typically much longer blog post so do enjoy this calm before the next storm of activity begins and let’s jump right into the week that was April 5-9, 2021.
First Guest Cabin Guest!
The biggest and best First this week by far, was the arrival of our dearest friends who flew half way around the world to spend two weeks with us as the Captain of Team Whack-A-Mole. Now THAT is a friend!
Some of you will recognize this “guest” who is really much more family as we have been friends and fellow sailors for a very long time and Christine and I have the great honour of being the godparents to all four of the children in this awemazing family.
Can you guess who this masked man is? Correct! John very generously left the rest of his family and flew all the way from Courtney British Columbia to be with us and as you can see from Captain Christine’s huge grin, we are both eXtremely eXcited to have our very first long term guest be such a very dear friend. Christine is particularly happy to have John join her in playing Whack-a-Mole with all the electronics systems such as navigation, Radar, AIS, Maretron and more. John is easily one of THE brightest people I have ever met and when it comes to resolving problems with computer networks and software he is an absolute genius so his plethora of skills has been put to VERY good use this past week.
This photo alone represents many hours of work and generated a LOT of grins onboard when John and Christine were able to get the TimeZero navigation software and the FLIR night vision camera up on both screens at the Main and Upper Helms.
As you can see it is daytime when this shot was taken but it is still fascinating to see how much the FLIR camera augments the reality that you are seeing up at the top looking out the front window at the Main Helm.
Here is a bit closer view for those interested and click to enlarge any photo to see more.
We will be maximizing John’s talents until he has to fly out at the end of this week on the 15th. Thanks SO much my friend, we literally could not have built this boat without you!
Rockin’ the Dock!
Christine and I have been sleeping aboard Möbius every night since she launched as a safety precaution just in case anything should go wrong with this newborn boat. And of course we have our two dock mates, these two Police boats which are about to head off to their new home in Oman, to help keep us safe as well. As you can see, Möbius and her two bow buddies are very close friends. We also have constant entertainment with the various “little” ships like this one that come and go on the other side of the harbour as they get loaded up with goods of all description and move on within two days or so. More ships all around us and each one quite unique and very fun to watch and learn.
Since launch we have been gradually moving out of our apartment here in Antalya and onto our new home aboard Möbius and we are now having all our meals onboard and now with John being our first Guest to sleep in the Guest Cabin. He gives the Guest Cabin two thumbs up and it has been a true treat for Christine and I to be answering all his questions and sharing our eXcitement of our new “baby” with him. As you can see in this and several of the other photos, the huge renovation of the Antalya Free Zone harbour continues all around us. And I do mean ALL around us!
Möbius can just be seen on the very far Right in this shot with the last of the major concrete pours about to go in for the huge superyacht haul out facility they are putting in here. And the Firsts that happened this week were not just onboard Möbius! We’ve been watching them build this tiny little 560 Tonne TraveLift for the past 2 months and this was her maiden voyage earlier today. We are now tied up this massive concrete dock that did not exist two weeks ago! Never a dull moment all day every day here as both construction and ship loading go on 24/7.
New eXtremely Solid Cleats!
You may recall that we had a very unusual wind situation when we were tied up next door at Setur Marina just after we launched which produced some very large swells coming directly into the harbour and marina causing all of us on the outer wall to surge back and forth for most of the day. All of the boats beside us suffered multiple snapped lines and ripped out cleats so we were fortunate enough to just have this one ripped off our our Swim Platform. Gives you an idea of the forces we were dealing with. The beauty of aluminium is that even these kinds of breakages are not very difficult to repair and we decided to “upgrade” our cleats from pipe to solid aluminium so we should be able to withstand such situations in the future. Uğur and Nihat machined the new solid AL parts and got to work inserting them into the existing pipes welded into the hull and then welded the new solid posts in place.
et voilà!
The new and improved cleats are done!
First Half Step Sea Trial
I gave you the best First we had this week right at the beginning with John’s arrival and saved the biggest First for the finale this week which is that we had our first Sea Trial on Tuesday!
Or first half at least. This was my first chance to bring Mr. Gee up to speed and load as we dialed in more and more pitch on the Nogva CPP prop.
We opened up the big hatch overtop of the Engine Room as the paint on Mr. Gee’s exhaust manifold burned in and produced some smoke.
Mr. Gee gave an eXcellent performance and soon had us slicing through the water at just under 10 knots barely breaking a sweat at about 1000 RPM and seemingly not much load.
However, a little bit later we had a sudden loss of oil pressure as it fell from its normal 40 PSI down to 20 so I shut him off to investigate. I wasn’t able to find any leaks or other evidence of the problem so we started back up and idled back to the dock. Hence my reference to this being a half step first sea trial.
I am now busy figuring out what caused the loss in oil pressure and will have more on that for your next week. We were super eXcited to have John be able to join us for our first Sea Trial and he was quite taken with the views and situational awareness that the 360 degrees of glass provides from the lower Main Helm in the SuperSalon. He shot this little video segment to show you .
The initial portion of the Sea Trial went eXtremely well as we brought Möbius up to just under 10 knots by slowly increasing the pitch on the Nogva CPP prop and Mr. Gee was still loafing along at about 1000 RPM. Here is a very rough video shot from the Aft Deck when we were doing about 9.6 knots. My apologies for not having time to edit this into a better quality video but hope you will enjoy coming along for the ride none the less.
** For those wondering, there is a lot of noise during this test run as we have the big overhead Engine Room hatch open as well as the ER door into the Workshop and the WT door into the interior all open.
For those of you who might care, we were also eXtremely happy with the wake we were generating at 9.6 knots and really look forward to the next sea trial when we can bring Möbius up to full speed and find out just what that speed is and what the wake is like at WOT or Wide Open Throttle. Stay tuned for that in the coming weeks.
As you can tell, Christine and I are both eXtremely eXcited to reach this new milestone of our first Sea Trial even if it was cut short for now.
Hope you enjoyed this short but sweet Progress Update and please come join us again next week. And please add any and all comments and questions in the “Join the Discussion” box below.
