Fiberglass Construction

Glen-L Flats Flyer Built by Jacob Kimbrough, Friendswood, Texas

For example, the bottom edge along the transom of high performance boats or along the inside edge along sponsons of hydroplanes should have a crisp corner for ultimate speed and performance. This illustration shows a good method for […]
