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.
We have spent this past week in the relatively small but very marine based town of Marmaris. For orientation, here is Marmaris relative to the others nearby islands and coastline around us. You’ll recall this map from previous posts and we started out in Antalya where Möbius was built and have been slowly making our way West and North along the Turquoise Coast. We spent the winter in Finike and left there to begin our cruising season back on May 17th. As you have read in the previous weekly updates since then we have stopped in Kekova, Kaş, Fethiye, Göcek and now Marmaris. We have spent the past week here in Netsel Marina in Marmaris and the arrow shows where Möbius is docked. The city of Marmaris itself isn’t that large but as you can see the marina is literally part of the city. Netsel is one of the 10 Setur Marinas along the Turquoise Coast that we have access to as part of our annual contract with Setur Marinas. If you click to enlarge you can all the red Setur Marina pins. Antalya is the most Eastern Setur Marina and then the other 9 marinas are spread out as the coastline moves West and North to Istanbul.
Christine’s Knee Update
This is a very large and very full marina and not usually our cup of tea but as I mentioned last week, Christine had torn her meniscus in her left knee and getting that fixed became our #1 priority and Marmaris was the best place to put in to. After several appointments with doctors in several other ports we stopped at along the way we decided that the best course of action was to go back to the same hospital in Antalya that we both had outstanding experience with while living there. Sunday morning Christine made the 6+ hour ride on a very luxurious bus that she said was more like an airline than a bus and on Monday morning she met with the surgeon who specializes in arthroscopic knee surgery at 9:30. After going over all the specifics of Christine’s history with this knee, their consensus was that arthroscopic surgery was the best choice. The surgeon asked “When would you like to have the surgery done?” and when she said as soon as possible he said “OK, how about tomorrow?”. Fifteen minutes later Christine was in a hospital bed being prepped for surgery on Tuesday. As amazing as this might sound to many of you, this is our experience with hospitals and medical care in Turkey and makes it easy to understand why Antalya in particular is such a popular destination for medical tourism.
Good news is that the surgery went very well and both the surgeon and Christine were very pleased so I rented a car on Wednesday morning, packed the pups and was in Antalya by noon to pick Christine up and bring her back to Möbius. She has been confined to the boat since then which has been challenging for her but as per the title of this week’s update, one of the ways in which “The Pressure is ON” is that she has been able to put more and more pressure on the knee as she hobbles around Möbius a bit better each day. While not something any of us would want this has been one of those good reminders of just how important our health and mobility is and as Christine soon remarked “I had no idea we had so many steps on this boat!”.
The surgeon wants to see Christine again in about two weeks so we are now thinking that it may be best to motor our way back East and get closer to Antalya for her follow up and to make sure that she has her knee well looked after. Stay tuned for updates on where we decide to go next.
Oil Pressure is ON too!
You may recall from the great oil pressure hunt with Mr. Gee, I had installed two oil pressure gauges after discovering that the original one had been falsely reading 20 PSI too low and causing me a LOT of angst until I discovered this. Mr. Gee now has over 40 hours of run time and has been purring along with a steady 35 PSI of oil pressure just as a healthy Gardner 6LXB should and so one of my jobs this week was to create the more permanent setup for monitoring Mr. Gee’s oil pressure. Here is the cleaned up and likely permanent setup on the four port bronze oil pressure manifold on the side of the oil filter. Moving down from the liquid dampened oil pressure gauge on top, the other three ports are:
1. black pipe that takes pressurized oil over to the valve rockers on each head,
2. Silver fitting that takes oil pressure through a flexible hose over to an electric oil pressure sensor mounted on the opposite side of the black oil filter housing
3. Low Oil pressure warning switch which will also provide power to the engine hour meter anytime Mr. Gee is running The silver canister is the electric oil pressure sensor which sends its analog data over to ……… …… this Actisense EMU-1 engine monitor which converts all the analog engine data such as oil pressure, oil & coolant temperature, CPP oil temp & pressure, into digital signals and sends these onto our N2K network that is used to communicate ALL the boat’s data to the boat computers and onto any of the six monitors we have on the Upper and Lower Helm stations as well as broadcasting this wirelessly to our phones, tablets and any other monitors we chose. This is an example of the kind of dashboards that Christine is building using our Maretron N2K View software which allows us to create virtual gauges, switches, warning lights, alarms, etc. We are slowly learning our way around this eXtremely powerful and diverse tool but we have a long ways to go and there really is no end to the different screens, gauge types, switches, alarms, lights, logs, graphs and other info we can display using this Maretron N2K View software. There is also a free Maretron N2K View mobile app which we have on our phones so we can also see all this data on these screens as well. Not something we use a lot as the larger screens provide a much more comprehensive collection of data on their larger real estate at each Helm but the phones are super handy when you are somewhere else on the boat and just want to check how things are working. I also tend to use this while I’m working on some system somewhere else on the boat and can use my phone to show me what’s going on as I adjust things in the Engine Room or down in the Basement where most of the Victron electronics are located. eXtremely handy and powerful and will only get more so as we learn to use these tools better over time and create all the Goldilocks displays that each of us prefer. Now that we had Mr. Gee’s oil pressure on the N2K network via the EMU-1, we were able to create the virtual oil pressure gauge you see here and with a bit of tweaking we were able to configure this so that the pressure shown on this gauge matched the PSI shown on the liquid filled gauge on Mr. Gee. Having all this data able to be displayed on any screen on the boat is a huge benefit while we are underway keeping us fully informed as to how everything on the boat is functioning. We have a LOT of work to do to build out all the various screens we want for different contexts but this is a good start for now.
Configuring the Auto Pilots
While I was in configuration mode I decided to also finish configuring our two Furuno 711C Auto Pilots. The 711C display head you see on the bottom Left of the Main Helm provides all the data and controls for our Auto Pilots and there is a duplicate setup at the Upper Helm on the SkyBridge. To the right of the 711C AP is the Furuno Jog Lever which is the second way we can steer the boat by simply moving that Black knob whichever way we want the rudder to move. The rotary switch to the Right of the Jog Lever is used to select which of the two helm stations is active. The two silver levers on the far Right are how we control the throttle and the pitch.
Took a few hours but all of these are now working properly and next trip we will do the final tweaks to the Auto Pilot while we are underway and can dial in the actual zero rudder position. These Furuno AP’s have the very great feature of “auto learning” and so as we use the boat more the AP system is learning the specifics of how Möbius handles, turns, rolls, etc. and uses this to dial in all the settings better and better over time.
Of course this being a boat, there were plenty of other little gremlins and “moles” to whack back down like the house water pump that I just spent the past 5 hours replacing today, but that’s how our start to yet another new month played out and I hope that yours was equally productive.
How can it be another month already and almost half way through 2022?!? However, with our recent reminder as to how precious time is we continue to be grateful for every day that speeds by and can only hope to have many more to come and enjoy each one as it passes.
Hope you will join us again for next week’s update and till then please be sure to add your comments in the “Join the Discussion” box below.
I’m not sure how it happened but another week and almost another month has somehow zipped by and it feels like Spring is finally in the air as the weather begins to warm here in Southern Turkey. Still a bit of a chill at nights but they are trending upwards and the forecast is calling for that to continue.
With Mr. Gee now back on his feet we are now ramping up our efforts to make Möbius fully ship shape and ready to head out to sea as the weather improves. It is now mostly all the little things that need to be done but they do take time and at the end of many days when I look around I don’t seem to see much visual progress but I does feel good to be checking items off of the To do list.
So let’s jump right in and get you updated on all that happened this week that I could photograph. Oh, and stick around for the Bonus video at the end!
Since getting Mr. Gee back up and running I’ve been spending a lot of my time doing all the “little” things on him such as getting all the various sensors wired up that measure things like oil pressure, engine oil, gearbox oil and coolant temperature.
If you look closely at this labelled photo (click any photo to enlarge) of the pressure and temperature senders on Mr. Gee you will notice that in addition to the analog gauges there is a second electric sensor that measures these same things. Here for example, is the Sika temperature gauge for the engine oil and on the left of it is the electric temperature sender which sends the oil temperature over to our Maretron boat monitoring system.
Over on the left side of the oil filter you can see the same combination of two analog oil pressure gauges and then a third electric sender at the very bottom. Over on the right front of Mr. Gee on the coolant manifold we find the analog temperature gauge and its electric cousin on the right.
It was finicky work running all the wires for these electric sensors and finding the best route to as I like to keep them well hidden and safe from chaffing so took the better part of a day to get these installed. Then I needed to chase a multi strand cable to get all output from these sensors over to the front Port/Left side of the Workshop where these Maretron black boxes and the Actisense EMU-1 are located. The EMU-1 is needed to convert the signals from the electric sensors and put this data on our NMEA2000 or N2K network which runs throughout the boat and carries all the boat data. This N2K network carries all the data to and from each sensor on the boat and allows us to display all this data on any of our many monitors onboard, our phones, laptops and tablets. This is the wiring diagram for the analog side of things with the wires from each sender going into the EMU-1. Which now looks like this. I will finish this job tomorrow by wiring the EMU-1 for the 24 volt power it needs. When we next have Mr. Gee running we can then check that the pressure and temperature data is showing up on the N2K network and Christine can build the screens to display all this info. We have done this dual analog/digital combination for most of the things we monitor on Möbius such as tank levels, water pressure, DHW temperature and many more. It is time consuming and costly but being able to monitor and log all this data is critical to being able to run Möbius safely and efficiently and to get early warning signals of equipment or systems as soon as they start to malfunction or fail. A big part of this is to be able to see this information from any screen anywhere on, as well as off, the boat so we find this to be well worth the effort and cost.
Having the backup analog gauges provides redundancy should any of the digital senders fail and also enables us confirm that the N2K data is accurate. As the recent mysterious missing oil pressure adventure proved, this double checking can prove to be eXtremely important!
My ER is Back!
Another one of those little and time consuming jobs was putting the grated flooring back in the Engine Room. We have used this composite grating in many other spaces such as the Workshop and Forepeak and it has worked out eXtremely well. Strong, solid, oblivious to any liquids and very non skid. Each grid has a frame surrounding it that is fabricated using aluminium L-bar which are then bolted to vertical L-bar supports welded to the frames. In the ER this grid flooring wraps all around Mr. Gee and is a huge safety factor when we ae underway and in rough seas as you always have a solid slip free floor under your feet. Not difficult work, just finicky to get the jig saw puzzle of all the individual frames fit back into their spaces and then bolted to their support bars.
At least in this case the results of all my time were very easy to see and it does feel particularly great to have the Engine Room back again since I first removed it back in June of last year.
Mr. Gee Video Tour Bonus
As promised, here is the bonus video so many of you have been requesting for so long. I don’t have the time to do any editing so this is going to be a very “uncut” and amateurish video I’m afraid but for all you Mr. .Gee fan boys and girls out there, hopefully this will hold you over until I can do a better version.
And for those who may have missed it, here is the video that was in last week’s update of the first starting of Mr. Gee version 3.0 after fixing the recalcitrant O-rings and finding the faulty oil pressure gauge that finally solved the mystery of the disappearing oil pressure.
Hope you enjoy these “rough and ready” videos from your trusty reporter and please type your questions and comments to let me know in the “Join the Discussion” box below.
