In total there are 4 sheets of marine ply for the sides. I don't have the precise sheet size but they had to be around 8 x 4 to be able to get planks around 7 ' long. It's a std size isn't it. Then there is the hull base which must be another 2 sheets. Thing is, I didn't cut out the blank sheets and I rather think that whilst 8' long, they were only a couple of feet wide because they would not have fitted on the bench. There are three profiles to be cut out as the boat is built of three layers. Hmm, this isn't making much sense is it.
OK there's the base board. 2 sheets cut in triangles with the bases together to make a huge diamond. Then the sides in three layers are all made from 4 identical pieces in each layer cut in a stack. The shapes were drawn onto the top sheets of wood hence it being vital that the cuts were vertical so that all three shapes resulted in 4 identical planks per set. As you can see the flat planks are cut in a curve so that when bent they form a curved hull. Just like a flat map of the world if you like, ends up round when you fold it.
Once it's boat shaped and you've packed it here and there, you paint the joints with resin and lay fibreglass tape on the seams then paint them in with more resin. The nose and stern though aren't taped. You can't get in there. That's where we used thick resin and hardener gobbed in. Very tricky. Personally I think expanding foam would have been a great idea.
Once that was set, the entire inside of the canoe was painted with a thin mix of resin and hardener to waterproof it. I think that to get a really perfect example, 4 days isn't enough. Prep is the key and because we had to reach particular stages at particular times some of the things that would make it better had to be rushed a little. I slapped resin all over the place thinking we'd be sanding it back, but we didn't. So the inside of mine looks very drippy. Tickling the planks right at the start to get them to meet without packing is important I think. Or you spend too much time sorting out the odd bits. Get it right and there's no tweaking to be done.
