Please opionions on best COMPOSITES for stringers

[gofastsandman]

George wasn`t at the shop. When recoring my coffin cover he asked me what I was using . I said marine ply and MAS epoxy.
He said he only uses epoxy below the water line in places that you don`t need flex. He said boats were designed to flex, not shear... He also said if laid properly wood and poly can and have lasted since the `60s . Glass doesn`t like to make extreme bends when laying up. The more you can fill w/ smaller pieces to build up the bend and lessen the transition angle the better. Also makes a stronger bond.
This was obviously a different job than stringers. I`ll bring more next time.

One other note , and this almost sent me in for an evaluation. Be POSITIVE that the marine plywood is not made with oil based glue. The poly will delam over time.

Still making mistakes and learning. My ply was made in Oregon and not oil based. Phenol Formaldehyde.

Sea Cast has extreme compression strength, not so sure of the tensile rating!
