old thread but for anyone searching have attached a good pic of inside a 1982 solid glass nacra 5.2 hull
most of the pic is the forward bulkhead, scrubed clean to check for cracks to the left is the side of the hull, you can see 2 stringers, with your fingers try to see if they move at all. movement is BAD the 2 screws at the top are main beam hold down screws the rectangular angled section at the top is actually the 1/4 curve that supports the alloy tramp beam at the very top is the inside of the inspection port, you can see the rivets holding it on to the top of the deck the worn white cloth edge is my shirtsleeve and above that is my hairy wrist ;-)
