Re: HULL SUPPORTS
Mine flexed while I worked on it. When I layed in my new stringers, I started with the farthest from center stringers first. I layed in each side, and let cure overnight. As I worked my way in (I had to lay in six stringers), the hull flexed less because it was gaining rigidity. You don't have to worry about it flexing while you are in it, just make sure the stringers are the right shape, and don't glass them all in at the same time. You could have some stringers curing with a weird hull shape beig caused by your body weight. There really isn't a way to prevent flexing unless you got a factory mold to lay the hull in, otherwise you could spend way too much time shoring up the underside of the hull. Just make sure you keep an eye on the hull bottom shape while you are working on it, to prevent any hooking, warping, twisting, and bowing. Good luck....
