Thanks to Christine and some tech support people at our web host provider, we now have all those technical problems worked out and I am able to post updates again. Yaaayyyyy!!!
My apologies for any annoyances you may have experienced with the test post and notification Email that went up here on the site instead of posting as a hidden draft only. I appreciate your patience and happy to be able to post this quick update on what’s been going on aboard the Good Ship Möbius the past two weeks.
Best thing that happened for me last week was that my Captain returned!
As you may recall, back on the 1st of the month, Christine flew over to Miami for some much needed Gramma time with our Grandson Liam, some visits with her family and friends and to look after a few medical appointments.
She had lots of fun outings with Liam, seen here goofing it up with a selfie of him and his Dad, Christine’s son, Tim. And timing was perfect for Liam’s first day in First Grade. Yayyyy Liam!
Meanwhile, over on the opposite coast near Los Angeles, our two Granddaughters Brynn (left) and Blair were also starting their first days of the new school year as well so school year 2022 is off and running!
Christine landed back here in Kalymnos on this ferry from Kos to Kalymnos on Monday (19th) evening after a two day marathon of travel. Being on this tiny Greek island adds several legs to the journey with three flights to get from Miami to Dulles to Athens to the neighboring island of Kos and then the ferry from Kos to Kalymnos. Oh, and did I mention that she was schlepping over 55 Kilos/120 Lbs of new bits and bobs for the boat and ourselves?! However, very happy to report that all went amazingly smoothly, checked bags went all the way from Miami to Kos without any intervention or loss, but it still requires lots of energy and time with not much sleep in between. She has slept VERY well the first two nights without any real sense of jet lag and we are both very happy to be back together and home.
One of the many bits of kit for the boat Christine lugged back with her, and one of the heaviest, was this Super Hole Hawg as Milwaukee calls their monster HD right angle 18V drill. Weighs in at 8 Kg/17.6 Lbs, has two reversable speeds and over 1000 FtLbs of torque. It is quite the beast and I was able to get a very good deal buying it through Home Depot with three of these super sized High Output 6Amp 18V lithium batteries which enables long continuous use between charges.
This is part of our style of doing prototypes of systems on Möbius that allow us to try out different ways of doing things and allow us to find out what is the Goldilocks just right way for us. In this case we are trying out this way of converting several of our manual winches to electric. I ordered this SS adaptor that fits into all our winches. Almost all winches no matter the brand, use this same star pattern for their manual winch handles so this adaptor enables us to try out this powered winch handle on any winch we have so we can see which ones would make sense to convert to full built in electric systems. As an added benefit, this power winch handle will also give us an emergency back up for any failure of our already 24V powered electric winches such as this hefty Lewmar 65 on the Aft Deck. Two of the currently manual winches we are most interested in trying this out on are these horizontally mounted winches on the Tender Davit which we use to raise/lower the Tender in the Davit Arch. Up to now we have been using the manual winch handles for this job which works well but we like to bring the Tender onboard every evening so this makes it much more convenient and faster. I will let you know how it all works out once we have tried it out a few times.
Much lighter and put to immediate use unfortunately, were six of these classic Victor rat traps which I was able to get delivered to Christine hours before she flew out of Florida. A few days earlier I discovered that I had a new and uninvited guest aboard and these traps are the best way I know of to get them to leave. Ruby and Barney donated a piece of their kibble for bait which I upgraded with a bit of peanut butter and had had several set out a few hours after we were back onboard Monday night. A few hours later we heard the distinctive and loud SNAP! of the trap under the sink and I escorted dead Rat #1 off the boat. Turned out he had two other buddies which were shown the same exit the next night and the traps have all remained undisturbed ever since. Whew!
Super Synthetics on Sale
For most of the lines we have onboard we use synthetic braided line such as Amsteel or Dyneema as they have SO many advantages such as higher strength that same size SS wire rope, very light weight, easy to handle and they float. As you might know or guess they are also quite expensive, especially when you buy them from Marine suppliers. But a tip I can share with you is that the same synthetic line is also now being used extensively in applications such as power winches for off road vehicles, emergency response teams and the like and buying these lines through those outlets is a fraction of the inflated marine cost.
So these two 30 meter/100ft lengths of 13mm/ 1/2” Dyneema also found their way into Christine’s checked luggage. These two are made for electric winches on the fronts of 4×4 and Overland vehicles so they come with a SS thimble on one end and a crimped on fitting for the end that bolts to the winch drum but it is easy to cut these off so I can tie my own eyes, loops or whatever ends I need. These two are going to be used for some of the rigging on our Paravanes which I now have everything I need and we can start testing out when we get underway again.
One of the other heavier items Christine brought back with her was this new stator coil for one of our 24V @ 250Ah Electrodyne alternators. Due to a manufacturing error, there was a short in the external rectifier and as you can see every third one of the copper coils was burned out. There are two of these coils in each alternator which produce the high AC current which then runs through the thick cables out of the Engine Room over to the external rectifier where it is converted into 24V DC current. Electrodyne quickly sent a new replacement coil several months ago and this was our first chance to get it brought over to Möbius. Fairly straightforward process to remove the old coil by first removing the aluminium Rotor that holds the permanent magnets for the alternator at this end. The holes in this Rotor provide good air flow to keep the alternator cool. These Electrodyne units actually have two individual alternators, one at each end of the Red housing but only the one on this end needed replacing. Once the old Stator windings are removed the trickiest part is fishing these three large gauge solid copper wires through the hole in the body of the alternator but just takes some time and holding your tongue just the right way.
Then I could bolt the new Stator windings onto the body. Rotor is bolted back on next and then all the wires inside the junction box up top can be attached to their respective studs.
This upper alternator is driven by a cogged belt system I installed, driven by the crankshaft and also powering the bronze sea water pump you see on the far Left. Further down, the second alternator is driven directly by the PTO shaft from the front Left of the engine.
Each of our Electrodyne alternators can provide up to 6kW of power and so with the pair mounted on Mr. Gee we effectively have a 12kW generator whenever he is running. Each external rectifier is connected to a WakeSpeed 500 Smart Regulator which automatically look after balancing the two alternators and keeping the 1800 Ah House Bank fully charged.
Speaking of Mr. Gee, I am eXtremely pleased to let you know that I am flying up to the Gardner works on Tuesday to be there when the new engine is put through its paces on the dynamometer for the initial breaking in and to create a full data sheet and graphs of torque, horsepower, fuel consumption, etc. I will be sure to take lots of photos while I’m there and be able to share those with you in next week’s update.
The new engine is due to start its return voyage back to us here in Kalymnos next Friday and hopefully will take “only” 3 weeks or so to get here. Given that the shipping up to Gardner took over six weeks, that will actually be quite fast! Everything is relative right? Once the new Mr. Gee arrives here I will be able to provide you with more details of the installation and most excitingly the results of the initial sea trials so do stay tuned for that.
Thanks for all your patience with the change of pace the past few months and please do keep your questions and comments coming in the Join the Discussion box below.
Quite a momentous week for us as we finished all the critical remaining boat jobs and on Saturday, July 1st we checked out of Turkey. Seemed like an appropriate date being Canada Day and a day that at times we were not sure would ever arrive. Our whole experience the past year or so has difficult to capture in words as it felt like some surrealistic blended version of the song Hotel California (you can check in but you can never leave) and the movie Groundhog Day where time got stuck and every day was Ground Hog Day all over again.
However our dear friend Sherry came up with the perfect description when she sent us a link to this fabulous cartoon by Scott Johnston over on the Mathematics Facebook group that summarized it perfectly. As most of you would likely recall a Möbius strip is this truly fascinating shape created when you take a strip of paper, twist it 180 degrees and glue it together into a loop. As you may recall from high school math class a Möbius strip is a one sided surface with no boundaries. If for example you try to draw a line down the middle of the strip you will find that the line keeps going till it rejoins your start point. If it’s been awhile since you played with a Möbius strip do yourself and others around you a favor and create your own out of paper and have some fun with it or just watch this short video for one of the classic things to do with a Möbius strip.
Möbius strips showed up on the “first date” Christine and I had but I’ll leave that story for another time and just say that this shape has captured our relationship from the very beginning. So much so that I designed our matching wedding rings by playing around with some ideas based on a Möbius strip. With the help of my friend Ted, turned one of my designs into a 3D model, 3D printed the model in jeweler’s wax and then used this wax model to create a porcelain mold into which the White Gold could be poured. Capture a split raw cognac diamond inside the twisted top and Voila! Sherry knows this story well and so she just had to send us that fun cartoon as soon as she saw it and you can see why this so perfectly captures our life of late and from the very beginning. Thanks Sherry!
One of the bigger jobs we checked off this past week was the completion of our new Davit Arch and the launching of our Tender Möbli.
I’ve gone over the rigging in past posts but you can see how we lift Möbli up inside this Davit Arch and then let the Arch rotate off the Port side where we lower Möbli into the water. Time was short but I took him for a quick test run out of the harbour and back and little Möbli performed perfectly and then we loaded him back onboard Möbius.
Christine took some video of this maiden voyage but I’m not able to get it to upload for some reason so I’ll bring you more in future updates.
You may recall in last week’s update that I starting building the paravanes or “birds” or “fish” as they are commonly referred to, which we will use to reduce stabilise Möbius in rolly sea conditions on passage. The ones I’m building are based on the design you see here commonly used by Canadian commercial fishing boats that I’m familiar with from my many years in the Vancouver/Victoria area. These paravanes hang from the end of the long aluminium tube A-frames you may recall me rigging up a few weeks ago and they glide through the water about 6m/20ft below the surface. As the boat rolls the paravane on that side dives down and then resists when the boat tries to pull it up as the roll goes the other way. Very KISS and all mechanical so much lower maintenance and less likely to break down. Last week I got the plywood cut to shape, all the edges rounded over and two coats of white epoxy paint on them. This past week I got the aluminium plate cut and welded for the T-brackets that go through the plywood and create the lifting point for the dyneema line that each paravane is suspended by. The two plates underneath will form the tail fins to help keep the paravane tracking parallel to the boat. Drilled all the holes for the line attachment on top and the four holes for the through bolts to fasten these brackets to the plywood, and rounded over all the edges to help reduce drag and be safer to handle. Used my circular saw and some files to cut the slot into the plywood for the vertical 10mm plate to slide through. Routed out some V grooves for the welds to fit into and keep the AL plate flat against the plywood when bolted together. Used some marine adhesive to seal the T-brackets to the plywood and keep everything watertight. Unfortunately I only had Black Sikaflex on hand but I will be giving the paravanes at least one more coat of White epoxy so they will end up being all white, not that it matters to their operation. I didn’t have time to complete the last step to complete these which is to cut the vertical Tail Fin plates and bolt them to the vertical T bracket and the plywood. Once that is all done they should be easy to rig onto the ends of the Paravane A-frame poles and ready for their first test run. We are now underway so I’ll be doing my best to get them finished along the way and will be able to report back to you as to how they work.
Are We There Yet?
Christine has been watching weather for the past week and a great window was forecast to open up on Saturday morning so Friday afternoon she worked with the officials at Finike Marina and got all the paperwork filled out, stamped and signed and just like that we were finally officially checked out of Turkey and cleared to leave Saturday morning!
Could this really be true??!?
We awoke to ideal conditions on Saturday morning, no wind and flat seas and we just had one more job to look after before leaving. Up to now we have been running on the initial 2000 liters of diesel fuel we put into Möbius’ tanks just prior to launching over a year ago. Not the greatest timing to be buying fuel but we “only” paid US$1.61 per litre which is much less than anywhere in Europe so that helped a to reduce the sting of the current fuel prices a wee bit. Our six fuel tanks hold a total of 14,000 Litres/3,700 USG but we will wait till we get to Algiers where diesel is now 19 cents/litre to fill up completely so we just took on 4000 Litres/1057 USG which will be more than enough till we get to Algiers.
Look out Greece, Here we come!
And with that, we motored out of Finike marina for the LAST time, for sure we hope, and started making our way up the Turkish coast, again for the last time we hope. We are headed for Rhodes where we will officially check into Greece and then make our way over to Athens in time to meet up with our two Granddaughters and their parents. They will be with us for two weeks as we explore the Greek islands with them. As former sailors we are still working on making the transition to voyaging under power and the dramatic change in what makes for “ideal weather”. Somewhat the opposite of ideal sailing weather, we now seek out NO wind and flat seas and that’s pretty much what we had for our all day trip from Finike to Göcek. Not at all difficult to get used to mind you and our two crew members seem to agree, just very different from what we’ve been used to while sailing around the world the past few decades. Christine wanted to go back to the idyllic little bay at the top end of Göcek that she had found for us last month when we were up here which made for a longer day as we didn’t get the anchor down till about 20:30 but still in lots of light and we had our tracks from the last time. However the late afternoon sun comes pouring into the SkyBridge and so the Captain adapted with this very fashionable headdress made out of one of our Turkish towels and all was well. And all well worth it when you’re rewarded with a great sunset like this as we made our way to the anchorage. We will probably weigh anchor early in the morning to get some favorable motoring conditions to make the 50nm passage over to Rhodes and get checked into Greece there and start making our way West across the Aegean Sea to Athens. I’ll be able to update you on that passage in next week’s update when we are in Athens with our four new family crewmembers onboard so do stay tuned for that.
Thanks for taking the time to join us here again this week and we hope you’ll be back again for next week’s update. Don’t forget to leave your comments and questions in the “Join the Discussion” box below.
Also sending out lots our very best wishes to all our fellow Canadian and American friends and family as you celebrate your July 1st and 4th independence days in style. Christine has a bottle of bubbly in the fridge for us to celebrate our departure from Turkey and arrival in Greece tomorrow so we’ll toast you all then.
Another very busy week here in Finike as we work our way through the last boat jobs that need to be completed before we can set sail (yes, we still refer to it as “sailing”) and finally put Turkey in our wake. In what feels a bit like some marine version of Groundhog Day (the movie), we thought we had left Finike for the last time about a month ago but life intervened with some new twists, quite literally. Christine “twisted” her knee and needed to go back to Antalya to get that operated on and when we first launched the Tender the overhead beam portion of the Davit Arch “twisted” and needed to be replaced. So we find ourselves back here in what was our home base for almost the past year to look after these and several other key items on our To Do lists. All working out very well as we know and like this area and have a good network of people we can call on to help find things we need which really speeds up the process and allows us to get these jobs done much faster than if we were in a new town.
Weather here continues to be outstanding and much “cooler” than past summers. Hottest we’ve been up to in the past few weeks is about 33-34C / 91-94F and nights have been down in the low 20’s / 70’s so makes for very pleasant evenings and sleeping and not too sweltering in the daytime though it does get toasty when you’re in the direct sun which I was for much of this past week and have the “farmers tan” to show for it. But we go for a swim in the ocean on the other side of the rock seawall behind us and that is a great way to cool down and good exercise for Christine’s knee which continues to improve and get stronger and stronger.
A good variety of jobs on the go this week including building DIY Paravanes, assembling and installing he new Davit Arch v2.0 and getting all its rigging in place. So let’s dive right in…………
Last week you may recall that I completed the rigging for the aluminium A-frames that fold out from each side of Möbius and have lines going down from their ends to a paravane of “fish” that glides about 6m/20’ below the water level. The rendering here is from when I was doing the calculations for line lengths so you are seeing multiple positions of the paravanes whereas there is only one on each side in reality. Paravanes are know as a “passive” system to help stabilize the motion, side to side rolling in particular, of the boat in large seas and in rolly anchorages. The other option is to use active stabilizers such as fins or gyroscopes which work very well and at more of a flip of a switch, but they require a lot of power, a lot of $$ and are relatively complex systems known to be quite prone to failures or at least a lot of maintenance and so we’ve chosen to go with all mechanical and very simple paravanes which are commonly used by commercial fishing boats. Our intent is to use this paravane system for the next year or so and if we decide we want to change to active stabilizers in the future, the hull already has all the internal framing and watertight coffer dams which will make the installation of active stabilizers relatively quick and easy.
FWIW, if we were to do go with active stabilization today we would probably chose to go with the Magnus Effect type of stabilizers as these can be folded inline with the hull when not in use. This greatly reduces the danger of hitting something with the fins that permanently protrude out much further and can add some risk when in areas with lots of coral, rocks or ice. And who knows what new systems might be developed by the time we might be looking into active stabilization? This is an example of the most commonly available paravanes from Kolstrand company and used by many commercial fishing vessels. Galvanized steel and work very well but very heavy and a lot of drag. However, some fellow Canadian boaters have been having very good success with these DIY paravanes built using plywood for the horizontal wings and a metal T-bracket to attach to the line above and a lead weight on the front, so I’m going with this design. Relatively low cost and easy to build and these will let me do a lot of experimenting in the next year of use to try different sizes of wing surface area, front weight, attachment line positions, etc. The ideal is to get the maximum roll resistance with the minimum drag. Over on the always helpful Trawler Forum, a trawler owner “Cold Smoked” had provided some photos of this type of paravane he was building and …. ended up looking like this. This is an example off this same style on the trawler mv Hobo all rigged up and ready to be tossed overboard. Here is a shot when this paravane is at work and helps to show you how the A-frame on this boat works. With the Paravane A-frames all rigged, this week I started building the paravanes or “fish” themselves. To my surprise, finding good plywood suddenly seems to be very difficult but on our trip to Antalya last week we were finally able to find a lumber shop that had some pieces on the side they were willing to cut for me. I worked out my best estimate of the various dimensions and scale for what I think will be close to the Goldilocks size of paravanes for Möbius and got to work cutting the plywood. My ever handy 18V Milwaukee router made it easy to put this bullnose profile on all the edges to help reduce the drag when these are flying through the water. Two coats of white epoxy to make the plywood waterproof and easy to see when deployed. I’ll add a third and perhaps fourth coat tomorrow and can then start attaching the hardware. Ideally I would like to have used a round lead fishing weight cut in half but could not find any here in Turkey so I’m going to use these large disc zinc anodes that I found in a marine shop when we were in Marmaris a few weeks ago. This one weighs about 7kg/15lbs and I will through bolt two of these to the bottom of the nose of the plywood.
Didn’t seem worth it to fire up Fusion 360 for such a simple bracket and fin so I just made this quick and dirty hand sketch as I worked out the dimensions and proportions for the T-bracket and the Tail Vane. I’m still tracking down someone in Antalya who has the AL plate I need and hope to have these here next week so I can finish building the fish for Möbius and start testing the whole paravane system out. Stay tuned as that happens. As I do with so many other systems, my intent is to use these first fish as prototypes and spend the first year or so experimenting with them to find that sweet spot of best roll resistance with least drag and all the tricks to deploying and retrieving them. This design allows me to easily change the size and shape of the plywood wings as well as trying different amounts of front weights with the different zinc anodes I now have onboard. And I can try different attachment points of the line to the fish to get the down angle just right and I try out different positions at different boat speeds in different sea conditions. Should be fun and educational so stay tuned for more as I finish building and start using these paravanes in future blog posts.
Mr. Gee 3.0 First Oil Change
Mr. Gee has now been thrumming away very happily for almost 50 hours now so this week I did his first oil change to make sure I could get rid of any particles that had gotten flushed out after the last rebuild. He holds about 28 liters and I use a 24V transfer pump to make it very quick and easy to pull out all the old oil and then pump in all the new. Mr. Gee has the optional hand pump for removing the oil so the oil pan is all plumbed for this and I just push on a vinyl hose and use the transfer pump instead.
Gardner recommends oil changes at about 400 hours so should not need to do this again until next year but I carry an extra 50 liters of 15W40 oil and several new oil and fuel filters so I can change these at any time.
Captain Christine’s Tech World
While I was busy with all the mechanical work this week, Christine continued her non stop game of Whack-a-Mole as she gets our complex set of electronic systems for navigation and monitoring all working and playing nice with each other. Not something that lends itself to much in the way of photos but trust me she works harder than I do! As just one example of hundreds, this is the screen she uses in Maretron N2K View to create the oil pressure gauge with all its settings, color coding, warning light, etc. It is a super system for monitoring everything on board but you pay the price in both cost and time.
Davit Arch Beam v2.0
When we first launched the Tender several weeks ago the overhead beam of the three piece Davit Arch failed and so we needed to have a new one designed and built. Fortunately Dennis, our awemazing Naval Architect at Artnautica in New Zealand, was kindly able to squeeze in my request to design this new version and have it fully tested by a structural engineer. As we had done with the design of Möbius, we were able to collaborate on the design via Email to exchange models and test results. Dennis was able to use some structural engineering plugins with Rhino3D that showed the various loads in all locations and guide us through the new design. Then Dennis sent it to his engineer colleague Peter who did the full set of structural testing and gave it his OK. All of this was then sent to Naval who also managed to squeeze building this new arch into their very busy schedule and had it build in less than a week. Next challenge was how to get this beam out of the Free Zone and trucked the 120km to where Möbius is in Finike. As usual the solution involved hiring a customs broker, paying lots of fees and completing lots of forms but eventually the bonded truck showed up at Finike Marina on Monday. Precious cargo inside. And we soon had it out of the truck and onto the concrete behind Möbius. The original two vertical legs of the Davit Arch were fine so it should have been a simple matter of bolting the three pieces together. However nothing with boats is ever easy and the new beam was 40mm too short. Grrrrrrr So I designed some adaptor plates to get the vertical legs in the right position and Naval kindly sent up a small crew with a welder and we were able to build and weld in the adaptor plates on Wednesday. With the new beam now fully bolted in place the next challenge was to get the new Arch lifted aboard Möbius, aligned with the hefty brackets welded to the deck and the 50mm OD SS hinge pins pushed in place. Fortunately crane trucks like this are ubiquitous in this area so Christine was able to quickly arrange for this one to show up.
Sure makes it easy to move heavy items from one spot to the next. The fit is very close so it took some time to get everything lined up so the hinge pins would slide into place as you have to get the bored pin holes lined up within about 1mm or the pins won’t slide in. But with some help by our local marina handyman Faik, we finally got everything lined up and the SS pins pressed in place. And version two of the Davit Arch was now in place and ready to be rigged. The rigging I had built for the first Arch had worked out fine but Dennis and I changed the Pivot Control Line blocks to be over on the far Port side (left in this photo) so that the angle the lines going to the beam were at the largest angle to reduce compression of the beam a bit. The lines you can see on the right going up the vertical leg is a 6:1 set of triple blocks which lead to the hand winch on each vertical leg. These lines lift the Tender Up/Down inside the arch to get the Tender up high enough to clear the deck chocks and the rub rail as it goes over the side. The Pivot Control Line goes through this 3:1 set of blocks and then …. ……. over to the big Lewmar 65 electric winch in the centerline of the Aft Deck. Davit Arch all rigged and ready for first test launch this coming week and I’ll bring you all of that and more in next week’s Möbius.World update.
And that’s a wrap for yet another week and almost another month! Thanks SO much for taking the time to join us and follow along on our adventures. Hope you will tune in again next week for the latest update and please continue to add your most appreciated comments and questions by typing them into the “Join the Discussion” box below.
Reminiscent of the line from one of the Godfather movies I believe “Just when I thought I was out; they pull me back in” Möbius is now back in Finike. Multiple factors driving our decision including that Christine needed to go back to Antalya for one or more consultations with her surgeon who did the arthroscopic operation to fix her torn meniscus and we needed to get the new beam for the Davit Arch brought to Möbius from Naval Yachts in Antalya. As you may recall, Setur Marina here in Finike was our “home port” since last July so we are very familiar with the area and know where to go to get things, who to talk with in our network here to get things done and a good safe spot to have Möbius tied up for a few more weeks while Christine continues her recovery and I get boat jobs done.
Marmaris to Finike
I spent most of the day on Monday going to different marine stores in Marmaris to pick up some of the lines and hardware I need for rigging up our Paravane stabilization system and doing some grocery shopping to stock up for the next week. Christine had found a lovely little anchorage on the charts that was just about 10 nm (nautical miles) from the marina in Marmaris so we untied from the dock and headed over there on Monday afternoon leaving Marmaris in our wake as per the photo. Though I must point out “What wake?” as I am just so pleased with how clean Möbius slices through the water. Thanks Dennis for the great hull design! We tucked inside a small bay with this small island just outside and enjoyed the sundown with some wine up in the SkyBridge with views like this. We had a bit of a rude awakening when a ferry went past the entrance at about 3am which rolled us so bad we almost flew out of bed. After picking up some of the items that had ended up on the floor we decided that we were wide awake and had a long run ahead of us so might as well just weigh anchor and head for Finike. We were rewarded with what was apparently a special “Rose Moon” and very flat seas as you can see so made the decision pretty easy. It was ideal motor boat conditions with glassy flat seas and no wind.
This is a shot of our wake or lack thereof at about 8.3 knots And this is the bow wave.
It was about 110nm down to Finike and these conditions continued the entire way. It was the longest continuous voyage we’ve yet taken aboard Möbius and gave us a good chance to test out running the boat for longer and longer runs as we get everything broken in and learn more and more about running this very unique and new to us boat.
I’ve discovered that our fuel flow meters have not been connected correctly so all my previous fuel burn numbers I’ve published are out by at least 40% so for this run I measured the actual volume of fuel removed from the Day Tank and used this to calculate the true fuel consumption. 109nm total distance traveled and we burned 169 liters so an average of 0.64 nm/L or 2.4 USG/nm which is right on my original estimates and MUCH better than the numbers I had been getting from the fuel flow meters. Just like the oil pressure gauge problems that vexed me in the past, I have once again been tripped up by assuming that the gauges were correct. Silly me!
The Turquoise Coast of Turkey was on full display for the whole day and this photo is typical of what the rugged rocky and forested coastline looks like.
Total trip time anchor to dock was about 13.5 hours so our average speed was 8.1 knots. We will continue to play with the various combinations of Mr. Gee’s RPM and the CPP pitch settings to bring the speed up more and more and find the Goldilocks “sweet spot” for speed, fuel economy and ideal loads.
Progress Update on Christine and XPM Hulls #2 & 3
We rented a car for Tuesday morning and drove down to the hospital in Antalya for Christine’s checkup and to get the stitches removed. Typical of our experiences with Turkish medical treatment at least at this hospital, it took less than 20 minutes from the time Christine walked in with no appointment to when she was back out front of the hospital stitches removed and an A+ report card from her surgeon. She is still not getting off the boat too much yet but the swelling is way down as is the pain and she is able to walk more and more around the boat so a full recovery is looking more and more likely. Doc said she could go swimming as of today (Sunday) so we will probably go for our first swim of the year when I get this blog posted. While we were in Antalya, we asked Naval Yachts if we could stop by the Free Zone to see how the two new XPM builds are going and this is what XPM78-02 “Vanguard” is looking like. And this is what XPM85-01 is looking like while still upside down getting all the hull plates welded on. She is due to flip right side up next month which is always a very big milestone in a build and we could not be more excited for her owners Andrew and Lili. A view of Vanguard from the rear Port quarter. Those with detailed eyes will perhaps notice that the owners have decided to paint the hull so you can see the first coat of primer has been applied to the hull sides. One of the major differences between our XPM78-01 and this second version is that it will be a twin engine/prop boat. These are the partially completed skegs that house the prop shafts. No change here on the Swim Platform with the doghouse for entering into the Engine Room and the same stairs on boat sides leading up to the Aft Deck. With twin JD engines the Engine Room will be much more traditional with a full beam layout but this comes at the expense of the Workshop we have in Möbius with the smaller central ER for Mr. Gee. The Basement has also been eliminated on Vanguard so the ER will also have most of the systems equipment located within as well. Up above on the Aft Deck the cantilevered roof is much longer and more substantial than on Möbius which will provide more shelter underneath and space for solar panels above. These are the drawings and renderings for one of the two guest cabins, this one located at the very front near the forepeak. Construction of the furniture for this cabin has begun and this will be the cabin for the Owners’ young son. Shower and toilet in the cabin’s Head. Probably the biggest single difference between Möbius and Vanguard is that they have replaced the Basement underneath the floor of the Salon with this spacious Master Cabin. To get the additional 1.2m of headroom needed, the tank tops have been lowered and the whole Salon has been raised. Provides a significant increase in the sleeping area but comes at the expense of storage so all part of the compromises of designing and building a boat that best matches her owners. The additional height is easy to see when you notice how the bottom of the Salon windows now sit about 40cm above the deck where they are almost flush on Möbius. Another very visible difference with the addition of these tall bulwarks that run down the entire length of both sides of the deck. Will make for a much safer feeling that many prefer when traversing these side decks. Seen from the Aft Deck of Vanguard, the stern of XPM85-01 shows how it too will be a twin engine boat and the two prop tunnels are easy to see now. A worm’s eye view underneath the XPM85 shows how the upside down framing is supported by the steel structure attached to the concrete floor of the shipyard. Still a long way to go and a LOT of welding but they are off to a good start as you can see looking up into what will be the Engine Room of the XPM85. Looking aft from the bow, the plates for the sides of the hull are being held in alignment by all these sacrificial AL bars. The plates are pushed/pulled into alignment and then these bars are tack welded to hold the plates in position for the MIG welders to sew together all the seams. Same “crash bulkhead” bow design and central anchor snubber nose cone. As exciting as it was to see all the progress on these next two XPM hulls, what really got our hearts racing was finding this completed new beam for the Davit Arch on Möbius! We are ever so appreciative of Naval Yachts getting this replacement beam fabricated in record time. All thanks to Dennis’ even speedier redesign and testing of this new beam so our thanks to all. I’ve arranged for a bonded truck to bring it from the Free Zone to Finike this coming week and with any luck I’ll be able to show you the new and improved Davit Arch installed and working on Möbius in next week’s update.
We have decided to go with passive rather than active stabilization, at least for the foreseeable future and will use a pair of A-frame booms that can be lowered to about 45 degrees off each side of the Aft Deck. The aluminium booms have been installed for some time now so this week I was finally able to do the rigging to raise/lower the booms. As with most of the other rigging on Möbius I am using synthetic rope most commonly known as Dyneema or Amsteel. As incredible as it sounds this new age line is stronger than multi stand stainless steel wire and is SO much easier to rig and replace. It is easily cut with this “hot knife” and I just wrap the location of the cut with grey PVC tape and then slice through the line with the red hot blade. This leaves a very nicely fused end on the line so it does not unravel and is easy to handle. This is the setup that will raise and lower the booms from vertical when stowed to about 45 degrees when deployed. Very simple setup with the end of the line attached to the bracket on the left which is about half way up the 6.2m/20ft long boom pole and then over through the black turning block and down to the winch below.
Deploying the paravane booms is a simple matter of slipping the line on the winch to lower the boom until ……
…….. the fixed length support line at the end of the boom goes tight. Looking up from deck level where it is easy to reach and turn the winch handle. Easy to see from this view from the dock. One side all done. Both sides done and this is what it looks like with both paravane booms fully extended. I grabbed this shot from some posts on the Trawler Forum boat “Hobo” to show what it will look like with the paravanes or “fish” as they are often called deployed when underway. Each paravane/fish is suspended by a 9m length of Dyneema from the ends of each boom such that they “fly” through the water about 6m/20ft below the surface and about 5m off the sides of the hull. As the boat tries to roll, one vane resists being pulled up while the other one “dives” down and sets up to resist as the roll goes over to the other side. A bit like the tight rope walker’s pole works. Paravanes also have the benefit of working at anchor as well so no more being tossed out of bed in a rolly anchorage! Some of my fellow Canadian boaters have come up with this design for a DIY paravane and I’ll be using this to build the first pair for Möbius. Plywood is surprisingly difficult to find here so Christine and I spent a few hours when we were in Antalya searching and finally finding a shop in the industrial zone that had some left over 20mm / 3/4” marine plywood left over and kindly agreed to cut the two pieces I need to build our paravanes. When finished our paravanes will look very similar to these also off mv Hobo.
White epoxy painted plywood with aluminium plate for the fin and line attachment. We will use Dyneema rather than SS chain as shown here.
That’s the story for the week of June 13-19 here in Finike and hope your week was similarly productive. Thanks for taking the time to join us here and please do add any and all comments or questions in the “Join the Discussion” box below. Hope to have you here with us again next week.
A day late in getting out this weekly update and I will keep it short but it has been both a very busy and successful week as we get closer and closer to our “throw off the dock lines” day. Lots and lots of jobs on the “Must be done before departure” list have been getting checked off and if all goes well today we hope to leave tomorrow!
Christine has been busy with electronics and computer related jobs onboard getting all six of our monitors working properly with the Upper and Lower Helm computers, getting internet connectivity sorted out for when we are underway and going up the coast of Turkey towards Marmaris and just playing that always fun version of Whack-a-Mole as each new “Mole” pops up. I’ve been busy getting the Tender and the Davit system ready to launch and yesterday we both worked on bringing 500kg/1100lbs of lead pellets aboard that are now safely ensconced inside the watertight coffer dams on either side which are there for the potential future addition of active stabilizers. But I’m getting ahead of myself so let’s jump in with a quick Show & Tell of what all we’ve been working on this past week.
Our workload has been reduced a bit with the addition of a new member of Möbius’ Crew, this little turtle who is one of many we regularly see around Möbius and inside the Finike marina. Turns out he just LOVES eating the green grassy growth that is already starting to appear along our black boot stripe and is a real pain to scrub off. As you may recall we hauled out a few weeks ago and gave our InterSleek “Foul Release” silicone based bottom paint a close inspection and found it to be just fabulous with almost no growth at all after almost a full year in the water with very little movement. However the black boot stripe above the bottom paint and waterline is a different story and this area which is kept constantly wet as the water moves up and down the hull a bit and is getting lots of sunshine all day long is the perfect garden for the “green slime” and grass like plants that grow here. No big deal for the boat really, just annoying and so we were delighted to find that we now had this new crewmember who likes nothing more than to munch away on the grass. Thanks buddy, we can use all the help we can get. Not sure about getting his visa for leaving Finike and Turkey but we’ll see.
As I mentioned earlier I got a good workout yesterday carrying 500 kg of these tiny lead pellets which we had purchased last year and have been sitting in a Bulk Bag on the dock behind Möbius. Christine worked on the dock to transfer about 40kg/88lbs of pellets into thick plastic bags that were then double bagged inside some heavy duty bulk bags which I then carried onto Möbius and down into the Basement under the SuperSalon. I had previously unbolted and removed the watertight cover plates over the two coffer dams on either side about midship on the hull which we had built just in case we decide in the future to add active stabilizers, most likely Magnus Effect type to help reduce roll more than our paravanes do. For now though, these watertight compartments made the ideal spot to put these lead pellets and improve the comfort of the ride by slowing down our otherwise “snappy” roll resistance. Working with Dennis our NA, we set up one of the design criteria for the hull to have a roll period that would have slightly less than the theoretically ideal roll period which is the time a ship takes from upright position to going to a particular angle on port side and then going to a angle on starboard side and then again returning back to upright position (zero list position) during natural rolling. We did this way so that we could dial in the Goldilocks roll period after the boat was built and fully loaded up to our actual weight/displacement. A shorter or faster roll rate provides more safety of returning the boat to upright but this faster or “snappier” motion can induce some nausea for some people and make crossings in rolly conditions less comfortable for the crew. Slowing down the roll is relatively easy to do by adding some weight/ballast that is further outboard and higher up than the centerline ballast, whereas speeding it up is very difficult once the boat is built. Hence we purposely went for a slightly faster roll period in the hull design knowing that we can then add some lead in the best locations once we have the boat in the water and in her natural trim and weight. So we will now operate Möbius with this additional 500kg of lead in the coffer dams which puts it well outboard of center and a bit higher up at just below the waterline, and se how this slightly slower roll rate feels and works for us. If we want to make further adjustments either way we can either remove or add more lead.
Being in small pellet form makes it easy to fill any size and shape spot we want and we are keeping them in these double bags for now so we can change if needed. Once we think we have the ballast and roll period at the just right, just for us Goldilocks point, then I will remove remove the bags of lead pellets, coat the aluminium with epoxy resin and then pour the lead pellets back into these spaces. Then I will pour some thickened epoxy over the top surface to fully encase the lead with the hull and keep it fully sealed to prevent any water from mixing with it which could set up some dissimilar metal corrosion.
As you might imagine this was a job that we were both very happy to check off the list and while we were certainly pooped at the end of the day we had big smiles on our faces and treated ourself to a “date night” of sorts and went out for dinner at the little café here in the marina.
Finishing the Tender Console
The other much larger job that got checked off the ToDo list this week was getting our tender we’ve named Möbli launched off the Aft Deck and into the water for the first time.
I spent the first few days of last week finishing up the last of the wiring that connects the Yanmar 4JH4 HTE 110HP engine to the Castoldi 224DD jet drive and the control panel and gauges for both in the center console. This Yanmar/Castoldi combination is a purposely matched pair and the two companies created a very complete kit package that provided all the custom wiring harnesses to plug into both the engine and the jet drive and connect these into the supplied instrument panel that is now mounted in the console. Most of these connections were done with very high quality quick connect watertight fittings but there were a few wires that I needed to look after to connect to the 12V AGM battery. A bit time consuming but not too difficult and this is how it looks so far. I’m very happy with how this has turned out so far and will work on getting the Standard Horizon VHF and Vesper AIS wired up after we launch and test Möbli out.
One more detail was to install the fuel filler cap in the cover of the 80 liter fuel tank up in the bow. I had previously installed the rubber fuel lines that run under the floor and back to the Yanmar so now I just needed to remove the cover plate, drill the hole for the filler cap and bolt that back down. Put in 15 liters of diesel for now and she should now be ready to start up for the first time.
First though, we need to get Möbli into the water so there is sea water supply for the engine’s heat exchangers for engine oil and fresh water coolant and for the wet exhaust system.
Most of you will have seen in some previous updates a few weeks ago that I had all the rigging for raising and lowering the Tender inside the Davit Arch as well as rotating the Arch itself to launch the Tender over the Port side. A pair of triple blocks provide a 6:1 mechanical advantage for the Tender Lifting lines that go to the winch you see here on the vertical leg of the Davit Arch. Inside the Tender at each corner there is a welded in attachment point where the Lift Line snaps into. Then there is a separate set of rigging that controls the pivoting of the Arch itself so that it moves the Tender sideways off the deck clear of the rub rails and then the Lift Lines are let out to lower the Tender down into the water. This Pivot Control Line of PCL leads through 3 blocks and then over to the bit Lewmar 65 electric winch which allows you to rotate the Arch out and back in. With that all hooked up it was launch time and little Möbli was soon testing out the waters beside Möbius. She sits pretty much right on the waterline predicted in the 3D model which was good to confirm and put the exhaust pipe a bit more than 150mm above the water. I could then hop in and start it up and was delighted when the Yanmar fired up at the first touch of the start button. Must have been taking lessons from Mr. Gee!
So an eXtremely big milestone for us and puts us in position to head out to sea in the next few days. Of course these are boats and so there are always those pesky little Moles that pop up and need to be whacked down. Two popped up with the Tender; there is a small pinhole leak where the Castoldi bolts up to the bottom of the hull and then the larger issue is some problems with the Davit Arch setup that will take more time to “whack” down. The leak is very minor and slow but to be safe I didn’t want to take it out for a test run but I was able to run the engine for about 20 minutes and test out the steering and bucket controls on the jet drive while Möbli was tied up to Möbius and get the oil and coolant up to operating temperature. All of that checked out perfectly; ran well, oil pressure and temperature were right one, steering and bucket control which is how a jet drive directs the thrust of the jet to move the boat forward, reverse and sideways. So VERY pleased with how the Tender turned out and can’t wait for that first test drive which will hopefully be in a few weeks.
For now though, the Tender is back in the chocks on the Aft Deck and all lashed down and covered ready for us to head out to sea.
Christine is working on a video collage of building and launching the Tender so watch for that to go live here in the next few days.
We still have a few small jobs to get done but right now it is looking good that we will be able to finally throw off those dock lines some time tomorrow and leave Finike in our wake as we start working our way up the Turquoise coast towards Marmaris. As usual we are on The No Plan Plan so we will take our time and enjoy stopping wherever calls our name as we motor up this beautiful coastline. We think we will use Marmaris as our jumping off point to check out of Turkey and head over the explore some of the Greek islands in June. Then we have our two granddaughters, with their pesky parents who seem to insist on coming along (just kidding Lia & Brian!) flying in to spend most of the month of July with us so that’s the ultimate prize that is driving us forward from here and a BIG part of what we have build Möbius for so we can’t wait for their return to join us aboard and make more memories together as we explore Greece and perhaps Italy.
As always, thanks for taking time to join us here and please keep those comments and questions coming by typing them into the “Join the Discussion” box below and with luck I’ll be sending the next update from some beautiful anchorage between here and Marmaris.
First and foremost my best and biggest wishes to all the Moms out there! Every day should be Mother’s Day in my opinion so I hope this is just an extra special day for all of you extra special people.
The past week has been filled with a litany of little jobs for the most part and nothing too visual to show you so I’ll keep this short so as not to take up much time on Mother’s Day or better yet, don’t bother reading till later this week.
Christine and I are inching closer and closer to the day when we finally throw off the dock lines here at Setur Marina in Finike and begin our adventures making our way up the Turkish coast a bit and then start making our way West across the Med this summer. If all goes well we hope to take off in about two weeks as we whittle the To List down more each day. Thanks to the help of the great people at Electrodyne and WakeSpeed I think we have found the causes of the one alternator and regulator that are not working properly and have the new parts being put together to be shipped out next week. With us about to become “moving targets” with no fixed address I will need to figure out how and where best to get these parts delivered to us but after so many years out sailing the world this is a very common problem for us and we always manage to find a way to get boat parts and boat united.
One of the big things I need to get done before we take off is getting our Tender “Mobli” finished and running and also be able to test out launching and retrieving him with our Davit Arch system. So in addition to working on some of the remaining To Do items such as tracking down some new gremlins in our Shore Power setup, I have been trying to stay focused on getting Mobli finished. Last week you saw me finish installing the wet exhaust system and I’m waiting the arrival of two more hose clamps to finish that completely and that leaves just the electrical wiring to be fully completed. So as per the title, wiring was the focus this week. Christine has been my trusted parts finder and delivery person tracking down the parts and supplies I need to complete the work on the Tender. She has taking taking full advantage of her fabulous new eBike to pick up parts available here in our little town of Finike or take the 2 hour bus ride down to the big city of Antalya to bring back parts from there. One of those items was a 12 volt AGM battery and battery box which I now have solidly mounted on this shelf I created using some leftover composite grid that we used for the flooring in the ER, Workshop and Forepeak.
I had several of these large Red Battery Switches from Blue Sea left over from building Möbius and so I installed two of these. that This under seat area is easy to access, fully protected, easy to lock up and keeps the weight well centered so this seemed like the best location for the battery. I installed the second battery switch in the Engine Bay on the opposite side of the AL bulkhead under the seat. This isn’t really necessary but provides a very secure anti-theft device when turned off and the Engine Bed lid is locked. We would not likely need to use it very often so it will just be left on most of the time but will be good to have if we ever need to leave the Tender ashore for long periods of times or we are unsure of the security ashore. The primary 12V positive 1/0 size Red cable goes from this switch under the Yanmar engine and connects directly to …. … this stud on the starter solenoid. A bit tight to get to but it is now on and well tightened. The other smaller Red AWG 8 gauge cable comes off the same switch and goes back to the jet drive along with the other wiring for the jet drive and the two Black hydraulic hoses for steering the jet drive. The steering is also hydraulic but is manually powered by turning the steering wheel. The hydraulic pump that raises and lowers the jet drive’s bucket is electric so that Red cable goes to this 50 Amp breaker which feeds power to the pump behind it. There is also the same size Black negative cable that runs from the engine ground to the bronze stud you can see in the center of this shot. Some nylon zip ties help keep all the wiring and hydraulic hoses in place and well protected and with that the wiring inside the Engine Bay is now pretty much complete. Just need to add engine oil, coolant and hydraulic fluid and this should be ready to fire up as soon as we launch the Tender and have it in the water needed for the wet exhaust and heat exchangers. Next week I will move back to the console to finish connecting the Castoldi jet drive wire harness to the Yanmar harness. That leaves me with these 8 wires that connect to the ignition and starter switches and the bucket position gauge which I hope to get done next week. Depending on if I get the remaining parts in time and finish all the wiring, we may be able to launch Mobli over the side next week and fire him up so be sure to tune in again next week to see all that. Thanks as always for joining us again this week and be sure to leave your questions and comments in the “Join the Discussion” box below. They are all VERY much appreciated!
Now, let’s all get back to reminding all the Moms in our lives how awemazing they are!
