What this video covers

Refining the interior and exterior of a custom catamaran involves extensive fairing, sanding, and structural bonding. To achieve a smooth finish in the master head, the crew applies Alex Seal finish primer to identify surface imperfections, using 180-grit sandpaper and a flexi sander to correct lines and low spots.0:11 They address uneven window cutouts by performing rough cuts before using a router to square the edges, preventing potential fiberglass chipping during final painting.9:49 On the exterior, the team bonds the cabin top sections using a methacrylate agent and reinforces the joints with two layers of 12-ounce double-bias fiberglass and peel ply.16:16 Structural putty creates the necessary coves for the glass transition.13:50 The project requires careful temperature management, as the crew works during unseasonably warm February weather to ensure proper curing of resins and fillers.13:25 Future plans include painting the interior high-gloss white and finishing the exterior cabin top with flat black paint before installing acrylic windows.18:09
