Man fits foam panel to sailboat hull extension
What this video covers
Johan and Malin extend their custom-built sailboat hull from 50 to 52 feet to create a larger swimming platform at the stern.▶ 11:57 The process involves cutting the existing hull at the original design line and constructing a new transom extension using PT foam sandwich panels.▶ 12:08 To shape the foam to the hull's compound curves, Johan makes 80 kerf cuts in the material.▶ 22:29 The team builds a temporary mold using narrow wood planks glued to the hull perimeter to support the foam during the initial interior fiberglass lamination.▶ 19:57 Before beginning the structural extension, they verify the hull's rigidity by taking measurements to ensure the structure does not shift after removing the final temporary frame.▶ 15:01 Inside the boat, the crew completes the guest cabin ceiling using 25mm PT foam panels and plans a recessed drawer for the nav station to maximize storage without obstructing cabin space.▶ 0:30 They finish the week by painting the bilges with two-component polyurethane paint.▶ 18:38
