What this video covers

Construction of a 42-foot MaxCruise catamaran continues at Kentmore Marina on Kent Island, where the builders install bulkhead six on both the port and starboard sides.2:22 To prevent the bulkheads from locking into the hull before permanent bonding, the crew places plastic bottles at the base during the dry-fit process, allowing for easier removal and trimming.8:09 Reinforcement of the bulkhead involves applying unidirectional fiberglass to the outer hull side and a combination of 090 and 12-ounce biaxial cloth above the aft bunk openings.0:05 For the final bonding, the crew uses cleats and clamped bars to maintain a plumb vertical line.17:43 They apply fillets with a 20mm radius using a custom-cut squeegee and secure the fiberglass with 12-ounce double-bias cloth in six-inch strips, overlapping the layers to ensure structural integrity.17:18 Separately, the crew applies a barrier coat to the bottom of a 31-foot Pacemaker powerboat using Total Boat products.12:19 Dry-fitting large structural components with temporary spacers prevents the panels from jamming in the hull during the alignment phase.8:17
