Stress by thermal expansion or when bulkheads and liners were installed can cause minor flexing.
How thick is gelcoat on a boat?
Many marine craft and some aircraft are manufactured using composite materials with an outer layer of gelcoat, typically 0.5 mm to 0.8 mm (0.02 in to 0.03 in) thick. Gelcoats are designed to be durable, providing resistance to ultraviolet degradation and hydrolysis.
