Thanks Strick,
I am leaning back toward marine plywood pretreated with epoxy, and puting it back together with vinylester resin.
If done poorly, like mine was, with unsealed holes for years, it almost made it 20 years. I don't know what the life of a hull is, but if it makes it to 40 with plywood, I won't complain. At 270 a 4x8 sheet, times 3 sheets, it really is piling up.
