Boat Bottom Repair in Sacramento

Fiberglass boat bottom / hull repair with Sacramento Boat Repair. Due to the nature of boating activities, fiberglass boat bottoms often have collisions with unseen underwater hazards. Boat bottom or hull fiberglass repair must be strong as the boat bottom does double duty. First, the fiberglass boat bottom must be water tight to enable a boat to float. Second, the fiberglass boat bottom must be both strong and flexible to withstand intense impact and vibration stresses. A boat going across the water at 30mph and hitting waves spaced every two feet will be impacting waves at the rate of 22 wave impacts per second. This creates tremendous stress and vibration so all fiberglass repairs must be done to achieve 100% of the original strength without creating any “hard spots”. The gel coat must be applied properly to keep it from peeling off while the boat is in service due to cavitation or water pressure and friction.
