E-bikes and Flying Fish

Sheesh!  Half way through the month of August already!

Time for a brief update on what’s been happening with us and Möbius over the first two weeks of August.

Weather here continues to surprise us with how ideally cool it is.  This past week has seen the daily temperatures drop a few more degrees from their previous norms of about 32C / 90F down to about 28C / 82F as I sit typing this at about 3pm on Sunday.  Evenings and mornings are even cooler and with the constant Meltemi winds blowing through the boat sleeping is very comfy and mornings are starting to feel downright chilly!  Not sure why this area is experiencing such relatively cool summer when the rest of Europe, the UK and many other parts of the world are seeing record high temperatures but we’ll just enjoy and be grateful that we’ve got such ideal conditions.

Here is what else we’ve been up to the past two weeks.

Update from Kalymnos Greece

IMG_1239_thumbChristine and I have settled into a nice rhythm here onboard Möbius and in this lovely south end of Kalymnos Island that I showed you around in the last post.

Kalymnos sat view_thumbThis satellite view of the island of Kalymnos (click to enlarge any photo) will help you see how arid and mountainous it is.  Möbius is the south harbour at the Red pin.  To give you a sense of scale, the coast road allows you to circumnavigate the whole island in just 68 km/42 miles.  So not too big which suits us just fine. 

Christine Update

IMG_1204Christine continues to be very dedicated to getting her knee back to full working order and goes for a swim each day where the surprisingly brisk ocean water is the perfect medium for her physio exercises.  Progress is slower than she’d like but improving.  This is but one of may swimming spots she gets to chose from every day.
IMG_1258And almost all of them have a beachside taverna so she gets to enjoy a Freddo Cappuccino and water in the shade when she finishes her exercises.  Thanks to her E-bike that she got before we left Turkey she is able to get to pretty much any of the swim spots on this end of the island in less than 10 minutes and with no strain on her knee, so all good.
IMG_1251The town itself is small but lively with daily arrivals of Turkish Gullets and other sail boats as well as lots of ferries that bring people to and from the surrounding islands or as far away as Athens.  Makes for good people watching including this very salty dog of a Captain.
IMG_1253As with most small towns though there are some less savory characters like this one who manage to sneak in when no one is watching.
IMG_1212In addition to swimming, Christine loves to use her E-bike which she calls her “Freedom machine” to explore further afield and she has been super impressed by how well the “pedal assist” of her trusty E-bike allows her to climb even the steep hills that are the norm everywhere on the island once you leave the waters edge.
IMG_1230Her explorations down random little roads and alleys continue to produce finds like this old church.
IMG_1229Which can often reveal surprise treasures such as this interior of the building above if you go up the stairs and push the door open.
When not out swimming or exploring, Christine is hard at work in her office every day here aboard Möbius as she starts doing the heavy mental lifting of creating a whole new set of characters and timelines for the newest book she is writing.  Stay tuned for more on that as it develops.

Wayne’s World

Meanwhile I am kept very busy with the combination of remaining boat jobs on the list and fixing the inevitable gremlins that pop up.  Our Kabola diesel boiler suddenly stopped earlier this week after working flawlessly every day for the past year and a half so trying to sort that out.  For now I’ve just turned on the 220V element in the Calorifier (hot water tank) for daily dishes and showers.

One of the unfinished boat jobs this week has been finishing building the paravanes so we can test them out when we next head out to sea. 
paravanes1As you may recall from previous posts, Paravanes are passive stabilizers which work by “flying” about 6m / 20’ below the water.  These help keep the boat level by resisting forces trying to roll the boat from side to side.  As the boat rolls, one of the paravanes or “fish” or “birds” as they are sometimes called, resists being pulled upward while the other paravane dives down and sets up for its turn to resist being pulled up as the roll forces go to the other side.

PXL_20220618_144026919The paravanes themselves, are suspended from Dyneema lines (super strong synthetic rope) that hang off of long booms extending out from each side of the boat at about 45 degrees.
LarryM fish in water with retreival lineHere is a paravane in action from another boat.

If you’d like more details on our Paravane setup check out THIS blog post and THIS one from back in June when I was rigging the booms and starting to build the paravanes.

PXL_20220809_114817402   Before we left Finike in Turkey I had finished shaping and painting the 20mm / 3/4” plywood “wings” for the two paravanes and bolting in the T-bracket where the line goes up to the boom. 
PXL_20220809_114751558Now I needed to cut these two aluminium plates to act as vertical fins that will help keep the paravane tracking parallel to the hull.
PXL_20220809_114751558Pretty straightforward to cut with my jig saw and shape with my angle grinder.
PXL_20220809_114815059Now just need to drill holes for the bolts that will attach the vertical fins to the T-bracket and the paravane wings.
PXL_20220809_124532184.MPLike this.  The holes along the top of the T-bracket are where the line going up to the boom attaches and provide adjustments for the angle the paravane will slice through the water at different speeds and conditions.
PXL_20220809_134200156Final step was to bolt on these two zinc weights that weigh about 15kg / 33lbs and create the nose of the paravane.  This forward weight ensures that the fish will dive down quick and smooth when not being pulled upward.  When the boat rolls the other way, the line pulls up which straightens out the fish and immediately start resisting the roll.  Rinse and repeat!
PXL_20220809_142948848_thumbHere is the finished pair of paravanes all ready for testing, though I will probably put on another coat of epoxy paint for good measure.

Next week I’ll finish the rigging and get the lines attached from the ends of the booms to each paravane.


IMG_1070Not too bad a spot to be in and we are eXtremely grateful for just how fortunate we are to be here.

I’ll be back with more as our time races by here in Kalymnos and hope you enjoy these briefer updates.  Let me know by sending your comments and opinions in the “Join the Discussion” box below and I’ll be back with more as soon as I have it.

Möbius; so much more than a name. Update June 27-July 3, 2022 XPM78-01 Möbius

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.

Mobius are we there yet cartoonHowever 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.
 
Mobius ring sketches (2)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.
Ring Compare shotsWith the help of my friend Ted, turned one of my designs into a 3D model,
Ring_example_0013D 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.

Mobius are we there yet cartoonSherry 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!

Möbli Launches!
.trashed-1659079411-PXL_20220629_071902358

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. 

IMG_1010I’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.


Paravanes/Birds/Fish

Canadian plywood   lead paravane WoodFish from Balder VIII on Trawler ForumYou 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.
PXL_20220618_133852317.MPThese 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.
PXL_20220626_115201694Last week I got the plywood cut to shape, all the edges rounded over and two coats of white epoxy paint on them.
PXL_20220701_074113950This 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.
PXL_20220701_091011432.MPDrilled 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.
PXL_20220701_114446009Used my circular saw and some files to cut the slot into the plywood for the vertical 10mm plate to slide through.
PXL_20220701_114508462Routed out some V grooves for the welds to fit into and keep the AL plate flat against the plywood when bolted together.
PXL_20220703_120730433Used 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.
PXL_20220703_120821245I 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??!?


PXL_20220702_061521384We awoke to ideal conditions on Saturday morning, no wind and flat seas and we just had one more job to look after before leaving.
PXL_20220702_070434755.MPUp 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!

ATurquoise Coastnd 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.
IMG_1032As 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. 
IMG_1036Not 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.
IMG_1038Christine 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.
IMG_1040And 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.

Holy Flying Fish Batman! XPM78-01 Möbius Update 20-26 June, 2022

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…………

Paravanes

Paravane rigging System v2Last 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. 
Paravane working flow illustrationParavanes 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. 

Magnus Effect stabilizer illustrationFWIW, 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?
Kolstrand paravanesThis 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.
Canadian plywood   lead paravane WoodFish from Balder VIII on Trawler ForumHowever, 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.
Plywood paravanes being built by Cold Smoked on TFOver on the always helpful Trawler Forum, a trawler owner “Cold Smoked” had provided some photos of this type of paravane he was building and

LarryM fish in water with retreival lineHere 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. 
PXL_20220619_123240022To 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.
PXL_20220623_080435142.MPI 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.
PXL_20220623_100209801My 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.
PXL_20220626_115201694Two 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.
PXL_20220626_115242034Ideally 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. 

Paravane bracket sketchDidn’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

PXL_20220620_083618615.MPMr. 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

IMG_0987While 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

Davit Arch v2 beam Pocket rod detailWhen 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.
Davit v3 loads from Dennis 26 May 2022Dennis 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.
Davit Beam v2All 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.
PXL_20220621_072505088.MPAs 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.
PXL_20220621_073108033.MPPrecious cargo inside.
PXL_20220621_074046241And we soon had it out of the truck and onto the concrete behind Möbius. 
PXL_20220621_142359199.MPThe 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
PXL_20220623_111925916So 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.
IMG_0992With 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.


IMG_0997Sure makes it easy to move heavy items from one spot to the next.
IMG_1001The 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.
PXL_20220626_144222934But with some help by our local marina handyman Faik, we finally got everything lined up and the SS pins pressed in place.
IMG_1003And version two of the Davit Arch was now in place and ready to be rigged.
PXL_20220626_083547840The 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.
PXL_20220626_083554027.MPThe Pivot Control Line goes through this 3:1 set of blocks and then ….
PXL_20220626_083625349……. over to the big Lewmar 65 electric winch in the centerline of the Aft Deck.
PXL_20220626_083631073.MPDavit 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.

Thanks!

Just When We Thought We Were Out; …… Möbius Update 13-19, 2022a

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

PXL_20220613_140841216.MPI 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!
PXL_20220613_162930803.MPWe 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.
PXL_20220614_010131475.NIGHTWe 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.
PXL_20220614_040449546It 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
PXL_20220614_041557378And 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!


PXL_20220614_084653028The 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.
PXL_20220615_122703063While 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.
PXL_20220615_122810000And 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.
PXL_20220615_122816018A 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.
PXL_20220615_123345893One 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.
PXL_20220615_123439385.MPNo 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.
PXL_20220615_123452450With 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.
PXL_20220615_123825454Up 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.
PXL_20220615_123916736.MPThese are the drawings and renderings for one of the two guest cabins, this one located at the very front near the forepeak.
PXL_20220615_124054850Construction of the furniture for this cabin has begun and this will be the cabin for the Owners’ young son.
PXL_20220615_124102153Shower and toilet in the cabin’s Head.
PXL_20220615_124227048Probably 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.
PXL_20220615_124929172.MPThe 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.
PXL_20220615_124937198Another 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.
PXL_20220615_125017670Seen 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.
PXL_20220615_125045587A 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.
PXL_20220615_125055189Still 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.
PXL_20220615_125333603Looking 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.
PXL_20220615_125345569Same “crash bulkhead” bow design and central anchor snubber nose cone.
PXL_20220615_125148319As 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.

Paravane Progress

Paravane rigging System v2We 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.
PXL_20220618_133023316As 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.
PXL_20220618_124329823.MPThis 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 ……


PXL_20220618_133653299…….. the fixed length support line at the end of the boom goes tight.
PXL_20220618_144447113Looking up from deck level where it is easy to reach and turn the winch handle.
PXL_20220618_133904146Easy to see from this view from the dock.  One side all done.
PXL_20220618_144003986Both sides done and this is what it looks like with both paravane booms fully extended. 
LarryM fish in water with retreival lineI 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!
Canadian plywood   lead paravane WoodFish from Balder VIII on Trawler ForumSome 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. 
PXL_20220619_123240022Plywood 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.
Plywood paravane exampleWhen 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.
