Are we finally ready to throw off the dock lines?!?! XPM78-01 Möbius Update 9-14 May, 2022

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.

IMG_0878Our 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.

Loading Lead

IMG_20210428_105421As 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.

PXL_20220511_103729569I 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. 
PXL_20220507_154630029Most 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. 
PXL_20220402_153959365A bit time consuming but not too difficult and this is how it looks so far.
PXL_20220403_124342482I’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.

Fueling up

PXL_20220513_113748356One 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. 


Möbli Launches!

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.

PXL_20220422_114808734Most 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.
PXL_20220421_141850258A 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.
PXL_20220421_141858103.MPInside the Tender at each corner there is a welded in attachment point where the Lift Line snaps into.
PXL_20220422_120336369Then 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.
PXL_20220422_114802065This 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.
PXL_20220513_141706186With that all hooked up it was launch time and little Möbli was soon testing out the waters beside Möbius.
PXL_20220513_141713223.MPShe 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.

Tender Wiring XPM78-01 Möbius Update 2-7 May, 2022

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.

PXL_20210508_142134749 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.
PXL_20220430_141100157Last 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.
PXL_20220507_154630029Christine 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.
PXL_20220507_154622505.MPthat 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. 
PXL_20220507_152943165I 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.
PXL_20220507_152949264.MPThe primary 12V positive 1/0 size Red cable goes from this switch under the Yanmar engine and connects directly to ….
PXL_20220503_153811831… this stud on the starter solenoid.  A bit tight to get to but it is now on and well tightened.
PXL_20220507_152938918The 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.
PXL_20220507_152922879The 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.
PXL_20220507_152934488Some 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.
PXL_20220402_154030638Next week I will move back to the console to finish connecting the Castoldi jet drive wire harness to the Yanmar harness.
PXL_20220507_111327451That 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.
PXL_20210505_073322984.MPDepending 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!

An eXhausting Week XPM78-01 Möbius Update 25-30 April, 2022

Another week and another month fly by in a flash it seems but we are making good progress and cutting the dock lines from here in beautiful sunny Finike Marina is getting closer with each passing day.  This week also felt like summer is definately on its way with day time temp yesterday getting up to a new high of 29C/84F so we tropical birds are loving this change.

Nothing too visually exciting for this week’s Show & Tell update unfortunately but I’ll do my best to get you caught up on what all we did get done this past week of April 25-30, 2022.

Decks are Done!

One of the larger jobs that we are very thankful to have finished is that the team from Naval finished redoing all the TreadMaster on all our decks. 

IMG_0667Despite being very high quality, the West Systems epoxy that was used to affix all the sheets of TreadMaster to the AL decks had not adhered to the AL very well so it has become both an eyesore and a tripping danger.  
PXL_20220425_081917085They carefully removed each panel of TM, sanded the AL down, applied Bostik Primer and then Bostik adhesive and glued them all back down with rollers.

Apologies for not having any photos of the completed decks but you get the idea.

Charging Issues

PXL_20210105_141245947When my friend John was here two weeks ago we finished setting up and configuring the two WakeSpeed 500 regulators which control the two Electrodyne 250 Amp @ 24V alternators.

This upper Electrodyne is powered off of Mr. Gee’s crankshaft with a toothed “timing” belt.

The six large red cables carry the AC current from each alternator over to the Electrodyne Rectifiers which are mounted outside of the ER.
Cogged Belt Pulley Fusion screenshotDifficult to photograph this drive system I designed so this rendering of my CAD models will show it much better.  Crankshaft pulley is at the bottom, sea water pump on the left and Electrodyne in the upper right.  Works out eXtremely well as there is zero chance of any slippage of these toothed belts and I put in a spring loaded idler pulley (not shown in this render) which keeps the tension just right all the time.
Electrodyne #2 jack shaft labelledAlso difficult to photograph now all the floors are in the Engine Room, the lower Electrodyne is powered directly off of the PTO or Power Take Off that is on the lower left side of Mr. Gee.  An eXtremely robust and almost maintenance free setup as well.
PXL_20210830_112735339This older photo when Mr. Gee was up in the air shows how this PTO drive works.
IMG_20200515_190541I went with these massively large and strong Electrodyne alternators in large part because they use an external Rectifier which is what you see here. 
IMG_20201007_130735The diodes in the rectifier are where the majority of the  heat comes from in an alternator and heat is the enemy of electrical efficiency so keeping them out of the alternator and out of the ER really helps to increase the lifespan and efficiency of the whole charging system.
PXL_20210830_112422607Each Rectifier is then connected to one of the WakeSpeed 500 Smart Regulators and each WS500 is interconnected with the white Ethernet cable you see here. 

Connecting these two WS500’s is a big part of what makes them deservedly called “smart” because they then automatically figure out how to perfectly balance the charging from each alternator which can otherwise be quite difficult and prone to errors.
IMG_20200515_131855However, the biggest reason these WS500’s are the first truly ‘Smart’ regulators is because they use both Voltage AND Amperage do monitor the batteries and adjust the alternators to produce the just right amount of charging. 
IMG_20200515_190603With everything all wired up we started up Mr. Gee and after the initial ramp up time we were soon seeing about 220 Amps going into the 1800 Ah House Battery which was a joy to see.


Electrodyne x2 paintedHaving two of these Electrodyne 250Ah alternators give us the potential for up to 12kW of electrical charging so in a way we actually do have a “generator” onboard.
Unfortunately we soon noticed that some of the 24V circuit breakers were tripping when these alternators were running and I’ve spent the past few weeks trying to figure out what was causing that.  Thanks to exemplary help from both Dale at Electrodyne and Neil at WakeSpeed, both of whom have been fabulous to work with from the very beginning, I was eventually able to track down the problem to an incorrectly installed aluminium bar that was used to fasten the two halves of the Electrodyne Rectifiers.  One end of this AL flat bar was touching one of the AL L-brackets that hold the studs and diode in the Rectifier.  Once found the fix was pretty quick and easy. 

However somewhere along the way one of the WS500’s stopped working so I am now working with Neil to sort that out.  In the meantime we have up to 250Ah charging capacity from the one working Electrodyne/WS500 combo and with all the solar power we have coming out of our 14 solar panels, we have no need for any of it most of the time.

Exhausting work on Tender Mobli

Most of my time this week was spent finishing off the installation of the Yanmar 4JH4 HTE 110HP engine and Castoldi 224DD jet drive in our Tender that we have named “Mobli”.

Similar to Mr. Gee and most marine engines, the Yanmar uses a wet exhaust where sea water is injected into the exhaust gas after it exits the turbocharger.  This water dramatically drops the temperature of the exhaust gasses so you can use rubber and fiberglass exhaust hoses to carry the gases and water out of the boat.
You can see the primary components I’m using to build the exhaust system in the photo below;
PXL_20220430_092530094water injection elbow on the Yanmar on the far Left with the Black rubber exhaust hose with the yellow stripe to carry the exhaust gas and water down to the cylindrical water muffler in the upper left.
PXL_20220430_130201688I will use the two white RFP 90 degree elbows to carry the water/gas up and out of the boat through the 76mm/3” AL pipe on the right.
PXL_20220430_141107025Like this.
PXL_20220430_141100157I am waiting for more of the SS hose clamps to arrive but this is what the finished setup will look like.  Will need to fabricate and install a bracket to hold the muffler in place as well and that will complete the exhaust system.

Hard to see (click to expand any photo) but I was also able to install the black rubber hose that you see running parallel to the left of the exhaust hose and muffler.  This carries the cooling sea water from the housing of the Castoldi Jet drive up to the intake on the sea water pump on the left side of the Yanmar.


PXL_20220430_141118761Last major job to complete the installation of the Yanmar/Castoldi propulsion system is the mounting of the battery and its cables to both the jet drive and the engine and I hope to get that done this coming week.
That’s how I spent my last week of April 2022 and hope yours was equally productive. 

Thanks for taking the time to follow along, always encouraging to know you are all out there and along for the ride with Christine and me.  Thanks in advance for typing any and all comments and questions in the “Join the Discussion” box below and hope you will join us again next week as we get May off to a good start.
