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.

Boat Bottom Repairs Before
A 26 foot boat ran aground. Bottom collision damage resulted in fracturing and gouging to the fiberglass bottom.
The boat is removed from trailer. The bottom fiberglass is ground feathering back a large surface and a inner surface mold set up. Fiberglass is then applied to develop proper lamination’s for stiffness, strength and flexibility. Sanded and then gelcoat is applied. This is then sanded with multiple grits of sandpaper for smoothness. Then the gel coat is buffed to a high gloss.
This boat grounded on the starboard chine against a rock. Fiberglass repairs are in process. Trailer is masked off and the damaged fiberglass was ground away, and new fiberglass laminate has been applied.
Fiberglass is then sanded smooth. Sanding and blending and area is followed by a color match and gel coat sprayed onto surface. A final color sanding is followed by buffing.
Sea Ray boat hit an underwater obstruction on Folsom Lake. The collision tore a large section of fiberglass off the bottom. This boat hit the underwater bridge on the South Fork in Folsom Lake.
The Sea Ray was removed from trailer. The broken fiberglass removed and the edges ground with a low angle bevel. New layers of fiberglass were added. Gelcoat color matched and applied with sanding and buffing to blend back in with original finish.
