The Vacationer is a plywood planked , flat bottom boat. The plans call for a layer of mat,(don't know weight), and 6 oz. cloth epoxied on. The interior of the hull will be epoxied only, using epoxy and microballoons fo fillets where needed.
In the case I choose a strip planked hull, I'll use a different design. In mind right now is the Port Louis 20 from Selway-Fisher. Since I haven't yet got study plans, I don't know the weight cloth recommended for the Port Louis.
I've read a lot about the unsuitability of polyester resin in boat construction.
I built a Nymph stitch'n glue dinghy years ago using polyester. It was good practice, but epoxy is the way we go on my last real boat. Also my first, by the way
