I just bought a 1972 24 foot Aquasport as my first boat. It needs some small repairs. First, some wood trim needs replacement. Any thoughts on the type of wood to use? It seems to me that marine plywood would be acceptable given the age, etc. of the hull. Second, the hinges on some of the hatches are loose. It appears that the screw holes in the fiberglass have expanded through wear so that they are now nearly twice the diameter of the screws. Any advice would be welcome. Thanks in advance.
