After talking with my brother, measuring the hull to any kind of accuracy will be difficult without the building board being perfectly flat. This is the same board I used last year but this is the other side. The bottom side is not perfectly sanded flat and has remnants of last years build left on it and it looks like the board has warped about 2mm on the front starboard side. The board is 48" long so its not much but not perfect either. Next building board will be a 2x8.
How about this for a building board system.

We build on a rectangular alloy extrusion 100mm x 50mm 1200mm long with 150mm wide ply top bolted onto that, and timber mounts bolted to that. Not only does it stay dead straight, but can be laid partly on its side, sticking up at about 60 degrees from normal to enable easy side planking and sanding, glassing, sanding, filling etc. Works really well, and saves a lot of bending over. Clamps into a vice well for glassing too.

Love the rear deck/hatches look - very reminiscent of old J Boat period decks. Edged hatches look great.

Great idea bbb, thanks for the link. About a year ago I picked up four off-cuts (30" long, a dollar a piece) of that material at a salvage yard. Looked too good to pass up and have been looking for a use for it....Thanks for the idea.....

Probably very similar to what Mr Cool (above) uses.

Cookie, Are you making fun of my total lack of modeling skills? That's discrimination! I mean I should be the one with the disabled sticker.

Do you mean set up my tent in Rufus' poop and stay awake all night listening to your drunken neighbors party? Thanks but no thanks. Howard Johnson for me this time.

The Keel/bulb and rudder are in the house. Thai-safepack makes a nice set for a good price and you can get a keel/mast trunk with it. I tested the ability to drain the mast trunk into the keel trunk and there is such a tight fit there is no free drainage. I weighed the keel/bulb and its 15g overweight so I'll start drilling the bulb from within the slot to remove the extra weight. I may also sand the top of the keel to see if I can get it further inside the keel box.

Last night I coated all the parts with slow cure epoxy. I used acetone and wiped all the parts to remove any oil from the wood and then applied the epoxy. I used a heat gun to warm up the epoxy and kept brushing it for 20 minutes or so. After 45 minutes I wiped most all the epoxy off the parts and left them to cure. This weekend I'll have them glassed as the 2 oz. cloth has arrived.

Group shot


Here are all the sections built to date. The wood is much lighter in color than last years model. I may do the glassing to the small parts tonight

Cut Loose


I got both sections cut free from the building boards this morning. Last night I got the 2nd coat of epoxy on the hull so both have 2 coats on top of the 2 oz glass cloth. I sanded the mating edges down to the top edges of the ribs before I removed the ribs. I then spent about 3 hours scraping and sanding and scraping and well you know the story. So this is the first mock up of the yacht. Next task is to get the transom in place to add some structural rigidity to the back of the hull then wax on wax off the interior more then soak some epoxy into the interior.

A friend builds in balsa glass sandwich and, like you, he's placed bulkheads in that divide his hull into 1/ forward of mast, 2/ centre keel, mast and winch, then 3/ rear servo & rudder with linkages above deck. However, his are sealed as waterproof chambers with breather tubes. Incredibly stiff and dry.

Your hull looking great.
