What this video covers
Sven Yrvind constructs a boom and reefing system for a shallow-draft, high-latitude sailboat intended for a 14,000-mile non-stop voyage.▶ 0:05 The build process involves securing sail pad eyes to an extrusion using epoxy and long screws to ensure structural integrity.▶ 0:50 Yrvind injects epoxy into the mounting points to saturate the area before inserting the fasteners.▶ 0:50 He utilizes a white mock-up to determine the spacing for the sail attachment points, which are set at 175 cm intervals.▶ 2:49 To complete the assembly, he cuts three bearing pieces and secures them with through-bolts, allowing the bearing shells to be installed directly onto the extrusion.▶ 4:04 The design incorporates these components to manage the loads on the boom during the planned transit through the Southern Ocean, passing south of Africa and Australia toward New Zealand.▶ 0:29
