What this video covers
Building a 50-foot custom sailboat requires extensive hull preparation, specifically sanding the strip-planked cedar to remove flat spots and excess epoxy before fiberglass application.14:17 To optimize the hull’s structural integrity, the builder raises the floor of the keel pocket by bonding boards with fast-drying glue and creating a radius with thickened epoxy, allowing for a thinner fiberglass layup on the exterior.5:01 This approach shifts the bulk of the laminate thickness to the interior, preserving the hull’s design shape and reducing the need for extensive exterior fairing.2:57
The project involves significant material removal across the 100-square-meter hull, necessitating a variety of power tools.8:06 The builder utilizes a high-torque polishing machine for rapid material removal, a Mirka random orbital sander with an 8mm throw for efficiency, and a Bosch sander with a forced-rotation turbo mode for versatility.7:50 A DeWalt drywall "giraffe" sander provides effective dust extraction and coverage on flat sections.11:38 The current phase focuses on surface preparation rather than final fairing, which will require long-board sanding after lamination.13:42
