What this video covers
Construction of a 50-foot custom sailboat focuses on the installation of the chain locker and forward bulkheads.4:27 To ensure a self-draining system, the chain locker floor is elevated approximately 20 centimeters above the waterline and tilted aft to direct water toward side-hull drainage holes.21:40 The structure utilizes 40-millimeter PET foam core sandwich panels for stiffness and weight reduction.8:37 Bulkheads are tabbed into the hull using a wide footprint of triangular PET foam and thickened epoxy to prevent hard spots.15:05 The design incorporates a large deck storage compartment for sails and gear, accessible via a ladder, with the chain locker positioned to allow for a 100-meter chain drop.20:17 Future plans include installing a jet-style bow thruster in the forward section to avoid the limitations of a traditional tunnel thruster in the shallow forefoot.24:35 The build relies on 3D modeling to ensure prefabricated panels fit the hull accurately.26:36
