What this video covers

Johan and Malin verify the hull accuracy of the keel recess by comparing physical templates to digital files.▶ 0:33 The keel recess curve deviates from the original design by two to three millimeters, requiring adjustments to the digital files before sending them to a machine shop for CNC cutting of a 20-millimeter-thick steel keel plate.▶ 3:08 To ensure a precise fit during installation, the plan involves using a release film and epoxy to fill any remaining gaps between the plate and the hull.▶ 3:53 The keel assembly will eventually incorporate 1.5 tons of metal and 5 tons of lead.▶ 4:52 Separately, the crew constructs watertight hatches for the forward cabin using PET foam sandwich panels laminated with 600-gram biaxial fiberglass.▶ 7:22 These hatches feature rubber seals and clamped brackets to provide water resistance for the under-bed storage compartments.▶ 11:58 The project also includes routing cable holes through a watertight bulkhead for the windlass and navigation lanterns, requiring waterproof sealing methods.▶ 16:59
