Fiberglass is used to build boats for many reasons. Chief among these are its durability, but also its easy to repair. You can patch boat holes in an afternoon and fiberglass a boat in just a couple of days. This article covers how to fiberglass a boat using epoxy resin. here
Structural reinforcements like stringers and bulkheads can be molded separately and then fiberglassed to the part, or may in some cases be laid up at the same time. While the hull is still open and exposed, items that will be located below deck level like fuel and water tanks or inboard engines can be mounted. This is also when plumbing and wiring may be run. Then the major components are assembled. For most modern powerboats, that means the deck and/or liner is lifted, often with a crane, and lowered into the hull.
Although many modern boatbuilders eschew the use of wood, on high-end custom yachts like this Jarrett Bay, methods like cold molding are often considered superior to more modern techniques.
Core materials are often used to reduce weight and increase stiffness. Some builders core the entire boat; others construct with solid fiberglass from the waterline down and coring above, and still others use some mix of coring and solid glass throughout the boat. here
Over the millenia people have built boats out of all kinds of stuff. Bamboo, leather, paper, concrete. You name it, someone somehwere has tried it. But by far the most popular contemporary boatbuilding material is a strange substance known as fiberglas.
The resin begins as a liquid and becomes solid after a catalyst or hardener is added to it. This is a chemical reaction that cannot be undone. Unlike thermoforming plastics like polythene and PVC that can be melted after they set and recast like metal, thermosetting plastics like polyester, vinylester, and epoxy become permanently solid after setting. Applying heat softens them a bit and greatly weakens them (indeed, they have very low heat resistance compared to most metals), and they may be set on fire, but they cannot melt and become fluid again.
The term fiberglass is itself somewhat misleading, as it describes just one component of what is actually a composite material. The other component is a plastic resin, usually polyester, although vinylester and sometimes epoxy are increasingly used these days. Thus the more accurate term is fiberglass-reinforced plastic (FRP) or glass-reinforced plastic (GRP).
Re: Can You Build a Fiberglass Hull From Scratch more
A buddy of mine who works at a local body shop brought up an interesting topic tonight that no one knew the answer to. Is it feasible for an every day 'Joe' like you and I to make a mold, spray it with a release agent, and mold a fiberglass hull in our own back yard?
If you're in the hotbed of boatbuilding in the SE or NE US there are places you can rent molds to build your own boats. Otherwise one-off boats are usually strip planked or cold molded by stitch & glue ply construction.
Of course I realize there would be a lot of finishing such as sanding and gel coat afterwards, but could it be done?
