As most of you know by now, Christine is American and I am Canadian so this was a big week as both our countries celebrated their independence within days of each other; Canada day on Thursday July 1st and today being July 4th for the USA. However, Friday July 2nd, was THE most special independence day celebration for us as this was the day we felt we and our new world aboard Möbius achieved our true independence. Why Friday? Well because that was the day that we took Möbius out for her maiden voyage and a whole set of firsts such as our first overnight on anchor. Hard to capture how this felt having been five years in the making but I’ll do my best, try to keep it short and let the photos do most of the talking with that “photo is worth a thousand words” thought in mind. Here goes ………
After waiting SO long for this to all happen the past few days have been a bit of a blur and reminds me of the “hurry up and wait” condition I learned in the Canadian military.
Mid day on Monday Christine went up to the marina office to let them know that we would be ready to launch in the next few days and they told her that the TraveLift was going in for service tomorrow so if we wanted to launch it had to be NOW!
Fortunately I had Mr. Gee all back together again and running the day before which was where I left off in last week’s update posting and the remaining jobs could be done in the water so we were good to Go!
This is actually the third time we have splashed Möbius here at Setur marina so it didn’t take them long to get the slings positioned under Möbius round belly and we had lift off in no time flat.
Down came all the vertical posts holding us up and we were headed for the TraveLift launch pads.
Which are less than 100 meters away so again, mere minutes.
We hover over the water for a few minutes and then down we go till the straps are loose and I can head below to check for any leaks.
All’s well down below, just the way we like it, not a drop of salt water to be found and so we give the thumbs up to the crew with our thanks and the TraveLift is off for its servicing leaving us floating merrily in the water at last.
Flange Alignment v2.0
One of the last jobs of putting Mr. Gee all back together again was to recheck the alignment of the flanges that couple the output of the Nogva CPP gearbox to the prop shaft.
If you have been following the whole Mr. Gee v2.0 rebuild you may recall that I left the Nogva gearbox bolted in place to the engine beds with the two anti-vibration mounts on either side so it *should* not have moved but this alignment is critical to smooth vibration free power transfer from Mr. Gee through to the 1 meter OD 4 bladed CPP propeller and as per the illustration above, the two flanges have to be near perfectly aligned with no more than 0.05 of a millimeter deviation. For reference a strand of average human hair has a diameter between 0.06 and 0.08 mm.
Not a difficult job, fist step is to remove the composite grated flooring and unbolt the sealed AL panel underneath to reveal the space where the prop shaft enters the boat. Then remove all 8 hardened bolts around the flanges, pull the flanges apart by sliding the prop shaft back a few inches and then moving it forward till the two flanges touch.
Then you use feeler gauges to determine the exact size of any gap between the two flanges. In my case the gap was 0.06mm so it only required a tweak with a pry bar on the front of the Gardner to eliminate that and then I could torque the 8 bolts back to a grunt worthy 240 Newton Meters and the propulsion system was good to Go!
It was also time to say bye bye to Mr. Gee’s original crankshaft and pack him all up for a safe trip back to Gardner Marine Diesel in Canterbury England where they will grind all the journals and have it ready to be installed in the next marine 6LXB engine they build.
At about 220kg / 485 Lbs, the wooden crate that GMD had made to send the new crank to me, would work well for the return flights and I added a few 2×2 timbers through screwed into the framing of their crate for good measure and one more component is Good to Go!
SkyBridge Lounge Act v1.0
As we are doing with many aspects of this very new boat, we are using this first year of living aboard to make lots of adjustments as we determine just how we tend to use various spaces and equipment and THEN we will build them in permanently. The most recent example is the layout and furniture for the upper SkyBridge area in front of the Helm Station.
What we decided to do is buy some inexpensive modular outdoor patio furniture which we could rearrange into various different configurations to see what we tended to gravitate to and use most often. Once we know that I can build in a more permanent set of furniture next year.
So Captain Christine has been on the hunt for the past few months at all the home supply stores here in Antalya and her choice arrived on this pallet on Wednesday.
The L-shaped sectional couch and glass topped table are made from aluminium tube covered with plastic rattan like weaving so they are super lightweight and will work well in our salty environment.
Minutes later, the Captain could take the new lounge setup out for a quick test drive and seems to be pleased with her choices.
I soon followed suit and am sitting here now typing up this blog post for you. Not a bad office, and one of several we no have onboard.
Wayne’s Newest Toy!
Christine and I are both running on fumes energy wise and so on Thursday we took the day off to drive about 2hrs north to the big city of Denizli where a brand new air compressor was waiting to be picked up. I had sent a new compressor over from Florida with all our other effects and boat parts a few years ago but it was DOA due to a faulty install and the best option for this critical bit of kit was to go for an upgraded new version which you see here on the Swim Platform Thursday afternoon.
2HP dual motors with dual compressors on each, 60L AL tank and super quiet!
I will soon be mounting this compressor under one of the AL workbenches in the Workshop where I will plumb it into the PVC pipes that run the full length of the Port side of the hull all the way up to the Forepeak with quick connect fittings in each area along the way.
I’ve had compressed air on boats for so long I can’t imagine a boat without and use it daily for powering pneumatic tools such as sanders and impact guns and being able to clear out debris from clogged tubes and just general cleanup. Also super handy for quickly filling things like air mattresses and our inflatable kayak.
Compressed air is also how I clear any clogs in our Sea Chest with a quick blast in the fittings installed in each plexiglass lid.
But perhaps our favorite use is to supply the air for our two Hookah regulators which allow us to stay underwater with just a regulator in our mouth, no tanks, to do maintenance on the hull such as keeping the silicone foul release paint super slick and clean or to explore some of the nearby coral and underwater life around Möbius. We will also have a 12V Hookah setup in the Tender to be able to enjoy underwater wonders further afield.
Maiden Voyage v1.0
Still not quite believing it, we seemed to finally be ready to head out to open ocean waters for the first time and have Mr. Gee take Möbius and us out for our Maiden Voyage! With everything from Mr. Gee to so many other systems being all new or on version 2.0, we spent Friday morning checking everything over multiple times, getting Mr. Gee warmed up, bow thrusters working, steering working, charting and all nav systems working and at 13:20 Friday July 2nd, 2021 we cast off the dock lines and headed out through the breakwater of the Antalya harbour to officially begin our latest adventure.
In a rare attempt at brevity to try to say how pleased we are, I will simply show you a set of shots of the wake we left as we slowly increased the pitch and thus speed through the water as we pointed Möbius’ bow to the horizon.
These shots of the wake behind Möbius at different speeds probably won’t be too exciting for many of you but for us, this is a huge part of the “proof of the pudding” from all the time we invested with Dennis in designing this hull to be eXtremely efficient for maximum speed with minimum power and fuel burn and to be slick, slippery and smooth as she slices through the water.
This is the wake at 7.2 kts off the Swim Platform.
Longer range shot still at 7.2 kts
20 minutes later, dialing in a bit more pitch this is what it looked like at 8.5 kts
Just a bit more speed with a bit more pitch but still keeping well under full load as we break in Mr. Gee very gently, this was our top speed for this first outing of 9.2 kts.
I will publish tables of data like this in the coming weeks but one quick shot for those curious, this is the EGT and Fuel burn rate at 8.5 kts with Mr. Gee spinning at 1500 RPM. For reference, EGT at full continuous load rating for Mr. Gee at 1650 is 400C
After two hours testing out different pitch/speed combinations, some hard turns and circles to familiarize ourselves with steering and handling Captain Christine headed us for this small nearby uninhabited island.
At her cue I dropped “Rocky” our 110Kg / 243 Lb Rocna anchor into the sea for his first bite of bottom sand. As usual for a Rocna he bit right away in about 30 feet of water, Christine backed down to give him a good pull for a few minutes and Möbius settled back with the 13mm / 1/2” chain hanging straight down in these calm waters.
First order of business?
Our first dives off the Swim Platform!
(you can just make out Christine about to enjoy her first dive into these cool clear blue Aegean waters.)
We swam around Möbius for the very fist time under Barney’s close scrutiny from deck.
While this view of the shoreline of the mainland off our Port side isn’t too bad, what was breathtaking for us as we did our first lap around Möbius, was to be looking up to see our visions we developed over all these past years now be a realty looming overhead.
Suffice it to say that our fist night at anchor was pure bliss!
Oh, and for those curious, Mr. Gee performed flawlessly throughout the 5.5 hours we ran him out and back on this Maiden Voyage. Here is a shot of his oil pressure and oil temperature after running at various loads for about 2 hours on the way back to the marina on Saturday doing about 8.5 kts @ 1500 RPM.
As happy as you can imagine we were when we returned to the marina yesterday afternoon after about 3 hours of more testing and maneuvering, we are even MORE excited here on Sunday night as we fly to Istanbul in the morning to meet our daughter Lia, husband Brian and our two granddaughters Brynn and Blair! This is a family get together that has been delayed for over 2 years and we are eXtremely eXcited to see this vision also become reality and I’ll have a bit more about this in next week’s post when we fly back here with all of them next Thursday.
Thanks for joining us through this eXtremely long and winding adventure that it has taken us to get here. Hope you have enjoyed it and we will continue to keep you posted as we switch into cruising mode and can provide more of the real world data and experiences aboard XPM78-01 Möbius that many of you are apparently anxious to receive.
