    Loose Amas

    Actually the tri was ADRENALIN AGAIN. It was proceeded by a Kiwi 35 which must have not been exciting enough. Come to think of it the Kiwi was a replacement for a highly modified Stilleto 27!

    2019 Worrell 1000 Reunion Race

    Getting too far behind the fleet after our dismasting in the 87 Worrell was the reason we got tossed from the lineup. Didn't make it to the checkpoint before the start in the morning by about 45 minutes and Mike Worrell hated to say "Thanks for the effort boys but we can't be responsible for looking boats that fall more than 24 hrs behind." Next breathe he asked if I wanted to join the Race Committee!

    2019 Worrell 1000 Reunion Race

    I'd consider a Weta. After my ill-fated attempt in 87, I was convinced that a 20' tri would be the ticket. I even drew up something along the lines of the Gougeon SLINGSHOT with a cross beam/hiking rack with a couple of small amas that would slide to windward. WETA would do well as a singlehand class. Plenty of them around.

    Hard vs soft dinghy

    Olaf Most of the work done in the shop was plain old Gougeon Slow resin. Being in the tropics we sometimes used the Gougeon Tropical but that was on large layups on the big cats that they built so I imagine it was just Slow with some Cabosil and milled fibers to give some body. The plywood bottom would have been well coated with plain clear slow resin first at least a couple of times and then sanded smooth. The important detail was to bevel the top edge of the ply so as to not have a hard edge that would wear against the hypalon of the tube. Another novel idea I got from my old boss in New Orleans Bill Seemann was using two part foam to permanently inflate and seal such tubes. In his younger days he had heard from oil platform divers how much effort was spent disassembling the extensive manifolds that join the maze of offshore wells to the production platforms. If you look from the surface at the various drill and production platforms out in the shallow waters of Louisiana what you don't see is all those pipes and valves and meters that link it all together and and it grows like a root system. They used to leave much of it in place after and area became non-productive but the cost to the net fishing and shrimping industry led to legislation to remove the old stuff. At first they just used explosives and blew the hell out of everything but all those pipes and manifolds had become home to dense concentrations of all sorts of sealife so further legislation led to laboriously disassembling in sections and raising those sections with big inflatable salvage bags and bladders. Of course any sailor knows how threaded fasteners tend to stay together after any time in the sea so even when they got the sections to the surface it mean't using cutting torches to further break the crap down for transport back to the steel recycling plants. Eventually the lift bags evolved into long sausages that permitted towing back to shore without breaking them up out on the Gulf to put on barges. Seemed like a good idea but chafe on the the bags and the strops made that an iffy proposition unless the weather was really calm. If you blow your bladder and lose the manifold you are right back where you started. Bill came up with the idea of blowing two part foam into the bladders which let them survive for a lot longer in more challenging conditions. I didn't get all the details of just how he managed to do that but I imagine that they used compressed air to get the load and bladders to the surface and did the mixing and injection of the foam into the still inflated bladders. I asked how one was able to get the foam distributed evenly in the long bladders without a whole series of valves in the bladder and he said that they would run the foam mix injection hose all the way to the far end of the bladder while still pumping air into it to hold the shape an then let the foam flow while slowly withdrawing it from the bladder. The foaming action would start at the far end and gradually progress to the valve which was left open to allow the excess to escape. He said there were some pretty spectacular blowouts in the beginning but eventually they got it all figured out and I think he made some pretty good money. I asked what they did with the foamed bladders after the tow to shore and he said that they held up so well that they just loaded them back on the supply boats huge cargo back deck and then when back at a raising site would use air inflated bladders to accomplish the life and then swap out the rigid foamed bladders for the ensuing tow. Big savings there. When the guys who came out to inspect the emergency life rafts in cannisters on the platforms themselves saw this, they approached Bill about blowing foam into those rafts when their 'use by' date had come. They got Coast Guard approval for that use and then the CG started extending the life span of some of their big RIB's. Bill let a friend and I blow an old small RIB in the shop and it was a good way to put an end to chasing leaks like BJ wanting to run his inflatable through the Krispy Kreme icing machine! The rigs you see are just the tip of a steel iceberg! Bags on a barge

    Iron Lithum chemistry is slightly less efficient but much safer against runaway discharge. Betts and his gang built an electric car several years ago when the boat building got slow so the have 'been there and have the T-Shirt'. Plenty of depth in that keel on top of the lead slugs and they should be safe down there. BMS circuits can isolate individual batteries if anything goes amiss. Lithium iron phosphate battery Specific energy 90–110 Wh/kg (320–400 J/g or kJ/kg) Energy density 220 Wh/L (790 kJ/L) Specific power around 200 W/kg[1] Energy/consumer-price 3.0–24 Wh/US$[2] Time durability > 10 years Cycle durability 2,000 cycles Nominal cell voltage 3.2 V The lithium iron phosphate (LiFePO 4) battery, also called LFP battery (with "LFP" standing for "lithium ferrophosphate"), is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO 4 as a cathode material, and a graphitic carbon electrode with a metallic current collector grid as the anode. The specific capacity of LiFePO 4 is higher than that of the related lithium cobalt oxide (LiCoO 2) chemistry, but its energy density is slightly lower due to its low operating voltage. The main problem of LiFePO 4 is its low electrical conductivity. Therefore, all the LiFePO 4 cathodes under consideration are actually LiFePO 4/C.[3] Because of low-cost, low-toxicity, well-defined performance, long-term stability, etc. LiFePO 4 is finding a number of roles in vehicle use and backup power.

    Hard vs soft dinghy

    There was a cruiser/liveaboard guy who took a job at Gold Coast in St Croix to replenish his cruising fund. He had an old inflatable transom dinghy that the 3 piece floorboards had just about given up. He got a few GC weekly checks in his pocket and order a new rollup floorboard inflatable dinghy with the newfangled slatted floor. The old beater laid around at the GC dinghy dock for a while until he decided that the flat bottomed slatted floor wasn't really any better other than quicker to deflate and stow. He was a surfer and the long haul out to the excellent breaks just outside Salt River were a long slow ride in the rollup dink. He and some of the other epoxy wizards came up with the idea to cut the leaky bottom skin of the old beater out but left a 4" perimeter as a bonding flange to the hull tubes. The old inflatable keel was scrapped. They took some 1/4 marine ply and cut a tapered gore down the middle to make a V shape at the bow that flattened out to the no deadrise at the transom. They then scribed it to match the tubes and placed it in the boat deflated and used the Hypalon flanges to bond all around to the tubes. A stout wooden cleat to fasten the new hard bottom to the wooden transom and some biax tape down the new keel inside out and it was better than new. Threw a 6HP on it and tossed it in the water and it was a real flyer! It was a fraction of a comparable FG RIB and they added a couple of running strakes and got even better planing and top end speed and it became the dink of choice for the morning patrol and after work surf runs. Even with two guys and boards it was up to the task and the deeper (than RIB) deadrise in the bow handled the chop and seas much better. The little dink that could became christened the "SURF SACK" and of course others followed. Wish I had photos.

    What do the chucks of cheese on the inside of the hull do? Snacks for the crew? That is an unusual incentive to progress with the work. Looks like Tillamook Sharp White Cheddar to me.

    A good buddy of mine brought that Procyon boats weird rig down once upon a time. The remains ended up behind the Windsurfing shack on St Thomas. First big carbon mast I had seen.
