    Hmmmm...what don't you like? We are going in a totally different direction than the stock 55 with our longeron but I'm curious what your objection is. We are doing a well for the furler to get the solent tack right down to the "deck". It'll also be similar to the Lorima style longeron with a big triangular cross section. If you've seen the MC2-60 or Fujin you know what I'm talking about. See below.

    We will have AOA adjustment on the T foil, so the idea is to reduce lift before moving the board. The Warn brake is rated to the full pull load, so we should be able to rely on that brake to full lift.

    We tried to make hydraulics work. The difficulty was the 2.3m stroke and 9 tons pull, 2 tons push. At 1:1 it was a 5+m ram, so the buckling load was significant. At 1:2 our ram length got shorter, but 18 tons of load got tricky and we were still left with a 2.5m ram (which was hard to hide inside the boat). 3:1 and 4:1 got crazy with loads. Magic Trim etc couldn't get us there. One feature I really liked was to use the board's lift as recycled energy, ie like a canting mast. You could drive one board down with the lift from the other side. That way you could avoid HUGE power packs and the needed ampacity. In the end, though, there was a simplicity to a big electric winch that was hard to ignore. $2000 from Amazon Prime is nice, too. I'm not convinced that this is the winning solution, this may be an area we revisit, but for now we have a plan.

    As the owner's buddy said, for the price difference between the Warn and the Harken, you can just buy a wheelbarrow full of the Warns and still have money left over. We will be mounting the Warns below deck, upside down and inboard, so they should be safe and out of harm's way.

    Fair point. I've put washboards on 2 of the 55's already. We haven't committed to them yet on this project yet, though. One reason is we should be sitting about 8" higher aft. Another reason we don't have washboards is we don't have engine rooms in back like the other boats. We still have the central, inside helm, so if things get sporty you can retreat to the wheel. But we may add washboards yet.

    We've got a fridge full of beer in the tent. Beer thirty is 4pm. Stop by!

    I've seen the ANTAL line drivers used for board up/down aboard the HH66's I was involved with. They're great, but in our application they're too low load (1500kg?). We'd need to go 6:1, and it'd have to be 6:1 up AND down The Harken are even smaller (300kg?). Dirk and the guys came up with a very clever way to use the Warn for up and down.

    We will have 3 fridge drawers, one freezer drawer, icemaker, drinks fridge, watermaker, plenty of fuel, electric induction cooktop and Bosch combo microwave/convection oven, ceramic toilets, holding tanks, and the usual seating on the 55's. It's only the custom hatches that we eliminated. We replaced them with flush Lewmar hatches. The cabin hatches and portlights will be as normal. We are planning to use electrotint window film in the hull topside windows, though. Cheaper and lighter and more effective than blinds. The boat is pretty damned stiff. I'm not worried. From leveling her up we found that when one corner lifted 2 other corners lifted.

    That's a good one. Actually, our current thinking is to use a WARN winch. One of the clever innovations to come out of NC is the use of a Warn Winch for the dinghy davit (1000lb). We used to put little Lewmar winches on the back deck. The 60's put on Lewmar Captive Reel winches. Heavy and $$$ but they worked. My guess is the boys in NC said, "screw that, I can pick up a dingy with a $500 winch from Autozone". They've been totally reliable so far. Warn make units that use dyneema and are rated to 16,000 lbs https://www.amazon.com/Warn-97740-16-5ti-s-Winch-Synthetic/dp/B01N3M2JN0. At 2:1 we should be ok. The whole system is laid out so you can bypass the Warn if (when) it shits the bed and take it to a winch. We spec'd a custom Harken captive reel winch but it cost about a year's salary (each) so we rethought our solution. We looked into hydraulic, but that was going to be tough.

    Long story short, they laid up the dry stack (carbon/foam/carbon) for 5514 in the tooling, but couldn't infuse because the resin that they had left was expired and they couldn't afford more. So they left the drystack in the tooling for weeks/months, uncovered. Then, apparently, some disgruntled employee took his rage out on the drystack and ripped it all down. They put it back up in place the best they could. Then, apparently PJ was getting really short on cash, so he instructed the workers to infuse the hull with expired resin, presumably to trigger a progress payment. I've heard this story from enough people that I accept it as true. To put it another way, we felt that this information was "true" enough that I wouldn't sell it when I worked at Gunboat. To clarify, the hull in question is 5514. There is no 5511, 5512, or 5513. I guess the buyers of 11 and 12 knew it'd be cheaper to walk away from their deposit than to move ahead, so those projects never began. Presumably, you skip hull 13 because it's 13. 5514 was the last boat infused. Last I saw it was still in the tooling.

    FWIW, there are 2 more unfinished hulls in NC. One is trash, but the other is in a great state of completion for completing. The tooling is also still down there.

    The aft bulkhead is in plane with the transom. There is a bunch of uni (pink and blue) and some biax (green). It is pretty cool how open the boat is, especially without the cabin back bulkhead. I can tell you from leveling the boat that it is a stiff platform. We'd jack one corner and 3 corners would lift. The T's are demountable, Zonker. Hopefully the rest of the board would survive. We started with the idea we'd rake the whole board fore-aft to change AOA of the T. It was a bit tricky, so now we plan to have the T AOA adjustable via a pivot pin/push rod. 9 tons of lift is a sizable chunk of load. Keeping the loads aligned took some thinking (on Dirk's part. I just nod knowingly in an attempt to make it seem like I understand what he's saying).

    Very nice couple. There were a lot of great folks who got burned. They had a funny line when I saw them at the Newport Boatshow a few years ago. They said, "we thought we were going to get a Gunboat. Instead, we got a Done-boat" (i.e. a boat that's already floating). They got a nice monohull.
  14. Soma, Am interested in the rebuild but also wanted to give you a forum to expand. Hope it's helpful for you and your venture. Michael

    Here you can see the rebuilt aft steps as well as the cockpit coaming. We left a downturning surface, sorta like a TP52/mini Maxi aft deck. You can also see how much wider the aft deck is (almost 2' overall). The removable panel is for steering system access. The tiller will come out of the trapezoid shaped panel on the top step. We also ditched the entire inboard sugar scoop. It was heavy and will help boarding from the dinghy.
