What this video covers

Johan and Malin are building a 52-foot sailboat and installing a curved transom to extend the hull by two feet.Watch To achieve the required curve, Johan constructs a mold from PET foam rather than using the deck as a guide, which would have required building complex temporary supports.2:21 He laminates the transom panel using three layers of biaxial fiberglass on each side, topped with a twill weave on the exterior to prevent telegraphing through the final paint.5:46 The panel is vacuum-bagged over the mold and weighted down with lead keel weights to ensure it holds its shape.6:40 After curing, the transom is trimmed and fitted to the stern.9:36 Johan then laminates the exterior of the stern in sections, applying five layers of fiberglass, including a twill weave, over thickened epoxy.15:13 He completes the exterior lamination in two sessions, totaling approximately 12.5 hours of work, before planning the interior tabbing.17:49
