Abstract
A transom for a boat is made of a metal grid structure filled with a hardened slurry of glass microspheres mixed with a polyester resin, the grid being covered on opposite sides by layers of fiberglass. The transom avoids the problem of rotting which is prevalent in wooden transoms when they are drilled with bolt holes for receiving outboard motors or other similar equipment.
