Re: Opinions on boat
Need to look thru some resto threads, and understand how boats are built. It will help you understand how best to take it apart, and how to put it back together......... More importantly, it will help you understand where & how to inspect during a pending boat purchase inspection.
A fiberglass deck is a POLYESTER RESIN & FIBERGLASS CLOTH covering OVER a plywood deck. The plywood is supported by stringers (long fore - aft running supports) and occasionally bulkheads (shorter, running port-starboard supports, like in front of & behind below deck fuel tanks).
Wooden stringers/bulkheads are usually encased in fiberglass & resin, for increased waterproofing & structural rigidity.
This ^^^ is typical, there are variations that include wood free stringers (Starcraft fiberglass boats of the late 60's were wood free stringers, I think, possibly later [or currently]), other stringers are foam filled, just something for the builders to drape resin & cloth over during production.
Some boats are made as 2 separate 'shells': a lower hull, and an upper liner that includes all of the interior finish surfaces. These liner boats (Boston Whaler among them) often have little to no wood below decks, but the space between the 2 shells is foam filled when the 2 parts are joined.
Your pending Starcraft is made from a hull (lower portion) and a cap (upper portion) and is joined behind the rubrail that runs around the perimeter of your boat.
As Ez said, closed bow runabouts aren't in great demand, and a fiberglass boat will require a substantial investment of time, energy & money. And is not an easy endeavor.
But dig around the resto forum, lots of great threads. Spend as much time as you can afford getting familiar w/ glass boats, the way they are built, taken apart, and where & how to look for problems. If only to use as a bargaining point w/ the seller.
If it's an SC American, they are well thought of hulls, and would make a worthy project.
