Basic Hull Construction. Increasingly, we find a new term being introduced to define what we once called a plain fiberglass hull, "composites." Composite merely means the combination of two or more materials to make a whole. Fiberglass, a combination of plastic resin and glass fibers, is a composite.
Hereof, what is a composite boat?
Modern Composites Used In The Marine Industry Composite materials are broadly defined as those in which a binder is reinforced with a strengthening material. In modern terms, the binder is usually a resin, and the reinforcing material consists of glass strands (fiberglass), carbon fibers or aramid fibers.
Likewise, people ask, what are boat hulls made of?
The hull of a wooden boat usually consists of planking fastened to frames and a keel. Keel and frames are traditionally made of hardwoods such as oak while planking can be oak but is more often softwood such as pine, larch or cedar.
Cut fiberglass sheets to fit over the weak areas in the fiberglass and any other area that you want to reinforce. Apply resin to the surface with a paint brush. Press the fiberglass sheets into the resin. Apply a second layer of resin over the fiberglass sheets.
