Gelcoat or gel coat is a material used to provide a high-quality finish on the visible surface of a fibre-reinforced composite. The most common gelcoats are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins which are applied to moulds in the liquid state.
The gelcoat (a smooth, hard polyester resin coating) is applied to the mould surface and is given time to cure before re-applying. Usually two coats of gelcoat are used. The barrier coat is applied to avoid fibre print and a rough surface through the gel coat. The barrier coat is cured in an oven and left to cool to room temperature.
Boats were often given Mediterranean-sounding names, and the boat classes within the model were often indicated by a model type then model name, with a hyphen in between. For example, in the 14-foot (4.3 m) range there was a model called the Lido, which came in three configurations: the Sport-Lido, Club-Lido, and Lido (standard).

The boat building industry provides for the design, manufacturing, repair and modification of human-powered watercrafts, sailboats, motorboats, airboats and submersibles, and caters for various demands from recreational (e.g. launches, dinghies and yachts), commercial (e.g. tour boats, ferry boats and lighters), residential , to professional (e ...
Fiberglass composite boats have been made since the early 1940s, [20] and many sailing vessels made after 1950 were built using the fiberglass lay-up process. As of 2022, boats continue to be made with fiberglass, though more advanced techniques such as vacuum bag moulding are used in the construction process.
