A fiberglass boat mold is typically made by creating a positive model of the boat, often from wood or foam, which is then coated with a release agent. Next, layers of fiberglass cloth are applied to the model, saturated with resin to form a hard shell. Once cured, the mold is carefully removed from the model, and additional finishing touches may be applied to ensure a smooth surface for future boat production. This process allows for the precise replication of the boat's shape and design in fiberglass.
