Matt corrects a structural error in the bow of his catamaran by installing a new, reinforced bulkhead.▶ 2:31 He originally positioned the primary bulkhead four inches too far forward, necessitating a redesign to ensure proper forebeam alignment and structural integrity.▶ 0:55 Because the original bulkhead was already glassed into the hull, he left a three-inch ring of the existing structure in place and built a new, thicker PVC foam-core bulkhead inside it.▶ 2:20 This modification creates multiple watertight compartments in the bow, which increases buoyancy and raises the position of emergency hatches to prevent leaks.▶ 3:32 The installation required splitting the new bulkhead in half to fit it through the hatch opening before glassing the pieces together.▶ 6:39 Separately, the project includes fairing the cabin top using Alex Seal Finish Primer, Total Boat Total Fair, and a combination of 6-inch orbital sanders and hand-blocking techniques to achieve a smooth finish.▶ 11:24
