[PSUBS-MAILIST] Newcomer With Question

[Fremitz13@aol.com]

I am a newcomer to this mailing list and would like to ask you all about a 
type of plywood I should use. For my first (Ever) project I am building a 
Delta Wing sub. If you arent farmilliar with it, it is a one manned craft 
that is semi-dry. I has a simple plywood hull and requires exterior grade 
plywood. All the wood boats that I know of are made with marine grade 
plywood, which I think would be the safer way to go, not risking it falling 
apart from it being saturated with water. I just want some oppinions on this.
