A technique I have used on several boats is to make a simple form of each
rib out of old plywood laying around. Cut your rib material about 1/8"
thick and as wide as you wish. Steam two pieces and clamp on each form.
When dry glue the two pieces into a laminate. They will retain the shape
exactly and you can finish as desired. The thinner strips are much easier
to shape and they have amazing strength and flexibility.
