    Looks fantastic Gib.
    Are you making any pre-weigh-in predictions?
    You have to be getting pretty close to launch now ... No?...
    The cabin should be snug and cozy.

    Thanks Skip.

    Tim,

    I predicted 3100 pounds. It came in at just a bit short of that.

    There's still plenty of work to be done.

    When I built the shop I anticipated some heavy lifting and built two of the trusses to accommodate. I hung 2 of 2 ton chain falls from them so I could lift both ends at once with the crane scale at one end first then at the other end. The straps are 3" and good for 20K pounds. I wanted 3" so that they wouldn't dig in.

    Just going to post 2 this time and see if I can get away with only having to do it once.

    It worked.

    Looks great as always Gib! I really like the scrubbed Cetol look. You thinking you'll be able to go check on your "family" next spring?

    Thanks Hugh, and yes, I'm looking forward to it.

    1400 pounds

    Big Dory Build 33 015.jpg

    plus 1600 pounds = 3000 pounds.

    There's still more weight in wood, equipment, supplies and 1500 pounds of lead beneath the floorboards to go for a total of somewhere around 5000 pounds plus me.

    The lower windsheild ceiling.

    Big Dory Build 34 003.jpg

    All of the ceiling is as removable panels so that I can access the inner face of the hull for maintenance, which hopefully will only be occasional spraying of borax solution, and inspection to see if moisture is accumulating between the insulation and the woodwork in which case the insulation will have to be removed or replaced with spray foam.

    I need to round over the edges on those beams. I've wounded myself a number of times on those sharp corners. I'll probably do it with my son's little trim router.

    Hatch covers are on. No fancy dovetails, just a frame topped with 2 layers of 6 mm Aquatek then surrounded again to protect the edges of the ply. I applied 5 coats of Varathane water based exterior satin clear. It's an experiment. If the finish is not as tough as they claim it will be easy to sand off and replace with more Cetol.

    Nice job,but I would have been more relaxed about the lift with a spreader bar in place.The building is clearly strong enough and a spreader would have reduced the crushing force on the hull.After that much high grade work a bit of damage from the lift would be very upsetting.

    Deck beams = spreader bars?

    The sheer on this hull is very stiff due to there being that very heavy sub decking and the entire deck assembly. There was no chance of failure.

    Over the last few years I've ruptured the long arms of both biceps. I had Lyme disease for 21 years before it was cured and it triggered an auto immune reaction to my ligaments and tendons. Being inclined to work hard I have ruptured 3 ligaments and 3 tendons since that started. So long as I take good care of myself and don't push my luck they remain connected, but the loss of 1/2 of each bicep has made it difficult to lift heavy items. The disconnected muscle tries to help but since one end is loose it just cramps. I've gotten used to it but it is annoying and even painful at times.

    So what has this to do with this boat? Well, I'm not really fit to haul an anchor, or to haul a prawn trap from 360 feet, or to lift the 150 pound outboard, so I'm building a davit and have purchased a winch/capstan, not sure which it is, that will mount on the after bulkhead of the cabin.

    It arrived via Fedex a few days ago in a big box. I was surprised at the size and weight, not dismayed, just surprised. It's rated at 250 pounds but just looking at and handling it I think they forgot one of the zeroes.

    Here's the beginnings of the davit.

    Big Dory Build 34 045.jpg

    The arm and the post are finger jointed together with epoxy. It's laid up from leftover material from the decking, which is 2 5/16 wide so I had to lay them up then resaw them into veneers and then lay them up to get the dimensions needed to lay the lot up as finger joints. Looking at it now I don't quite get it, but it made sense at the time, and it looks cool. I'll finish it bright with Cetol.

    I call it Damascus wood.

    This was supposed to be with the hatch photos.

    I got tired of woodworking so spent a surprising amount of time priming with System Three S1 CPES, sanding and applying paint. There will be more paint later.

    I was quite surprised to see that I was in the picture that I had taken. Looking more carefully it became obvious that "I" was actually the post behind the boat seen through the windows.

    This is the Cubic Mini Cub that will be keeping me warm from time to time. It's very well built, I like it. I'm contemplating removing the rail and bolting down a larger cook top of 1/8" steel.

    The company, in Quebec I think, was very nice to deal with and it arrived a month earlier than expected.

    Big Dory Build 35 006.jpg

    Somewhere in all of that work I made up the hand rails, not all that similar but inspired by David G's handrails on that lovely sailboat of his. Once the cabin tops are painted I'll peel off the masking tape and epoxy and screw them in place. I already hung off of one of them with just the 4 screws holding it on and it held well. With epoxy and screws it will be solid city, which is appreciated since I made the side decks too narrow for toe rails.

    More of leftover decking, with tracers of red cedar.

    Wow Gib. When I first started following this thread I thought you were going for a simple workboat-style dory for some coastal cruising. Now I see that you are building a proper little yacht. Careful with all that varnish though. Pretty soon you will be thinking about gold leaf for her name and polishing the bronze fittings to a high gloss. Eventually she will only see the open water for picnicking on nice, sunny, calm days, and the wolf pack will wonder where you went!

    Ya know Gib. You have put all the folks here who have ever posted a build thread to shame. The speed of your build, plus the attention to detail is unacceptable. Just slow the heck down and make a few mistakes now and then.

    Well that's nice you guys.

    Mistakes? Side decks too narrow for toe rails. 9' 3" beam requiring a wide load permit every time I want to move it. There must be more but thankfully my memory forgives me.
