I've just begun what is looking like an extensive restoration of a fiberglass 40' Drift-R-Cruise. The boat was through some good owners, but saw its share of reckless patch-job attempts. I've gutted it down to some badly rotted wood flooring and interior plywood structural sheathing. The hull's in good shape, but it'll take a good bit of new truss and glass work at the flooring and superstructure level. Can I assume this is an epoxy glass structure, without polyester? It's quite thin in place and I'll likely put another _layer_ on the outside as well. Any original structural information would be great.
