Thanks Jimsky! I will alternate on the lower hull. The upper half has a lot of extra support on the frames, if you remember I added the spacer boards in between every frame. That’s not moving!

As far as the clamping, I rarely do on the hull. I used nails on some of the more extreme bends at the bow. Then after I removed them, put some glue in them and sanded while the glue was wet to fill with saw dust.

Instead of using clamps on the hull, I soak the boards in hot water for about 10 minutes, then towel dry. Then I add wood glue on the edge, and then put CA on the frames. The CA cures almost instantly with the damp boards, similar to using accelerator. Only in the extreme bends do I need a nail to hold. But if I pre bend good enough, then I can usually get away without using anything. On the lateral bends, I nail a small piece of plank above the area that needs to be pushed down. That way I don’t nail into the board. I hate I had to use nails at all. But I’m adding the treenails later above the water line. So the few I had to use, will most likely not be visible. Below the water line will be painted white.
