What Effects does galvanic corrosion have on fiberglass boat hulls?

Galvanic corrosion primarily affects metal components on fiberglass boat hulls rather than the fiberglass itself, as fiberglass is non-conductive. However, if metal parts such as through-hull fittings or hardware are not properly protected, they can corrode, leading to structural weaknesses and potential leaks. This corrosion can also lead to increased maintenance costs and safety hazards if not addressed promptly. Ultimately, while fiberglass hulls are resistant to corrosion, the metal components can significantly impact the boat's integrity if galvanic corrosion occurs.
