What this video covers
The crew of a sailboat undergoes extensive hull repairs in a boatyard, focusing on structural integrity around the rudder skeg and through-hull fittings. After discovering that the hull is cored below the waterline in certain areas, the host grinds away damaged fiberglass to expose and replace rotten core material.1:34 To remove stubborn through-hull fittings sealed with 5200, the host uses a heat gun to soften the adhesive before extraction.6:03 The repair plan involves replacing the original cored sections with solid glass, utilizing seven layers of 1708 biaxial cloth and thickened epoxy to ensure a structural bond.22:17 Additionally, the crew removes an aft water tank to accommodate a new water maker installation, a process complicated by the tank's original construction and adhesive mounting.10:20 The host also strips failing Interprotect and bottom paint from the hull and rudder, grinding out numerous cracks along the waterline to prevent future delamination.21:19 The project concludes with the application of new glass and epoxy filler to restore the hull to a solid, watertight state.30:09
