Of course, I stressed about the alignment of the forms, and moved a couple, but I also realized that every kayak I built in this small basement looked crooked while I was building it.
I used only one "cheater" strip, in the bow. I found that the bow & stern curves were not too extreme to deal with, and in a way, were actually helpful-more twisting & clamping, but less beveling of the strips at the bow & stern.
None of the boards I worked with are full length. I have to scarf two strips together to make a full-length strip. I actually find this easier than handling a bunch of 19' strips.
