Well, I had my doubts about "thousandth of an inch" accuracy but wanted to check anyway, because there's a lot I have to learn about this process.

Yeah, I guess I found that out with my warped plastic hull! At first, I thought it must be my imagination...time and many paddles convinced me my eyes were seeing correctly.

You should see it when the sun is shining strongly from one direction, which is usually the case in this climate. The bow bends to the shady side. Degree of bend varies, but seems to be related to air temperature. It will curve to left or right depending which is the shady side, but even when "neutral" (in the shade/in the shed) it has a slight curve to the left.

Fortunately, wood and glass seem to be more rigid than plastic. So as long as I build it straight, I can kiss the banana syndrome goodbye.
