What this video covers

Sven Yrvind installs two side-by-side masts in his workshop for a small, shallow-draft boat intended for a 14,000-mile nonstop Southern Ocean passage.▶ 0:18 The mast design utilizes conical fittings that create a high-tension, secure lock when seated.▶ 0:52 To prevent the masts from jamming permanently into the conical base, Yrvind measures and cuts the masts to a length of 230 centimeters and adds a physical stop to limit their depth.▶ 2:09 He secures these stops using a constrictor knot coated in epoxy.▶ 7:58 The masts stand 172 centimeters high at the top and 95 centimeters at the bottom, with a 170-centimeter distance between the tops.▶ 7:09 Yrvind routes electrical cables through the masts to support navigation lights and an AIS unit.▶ 9:37 He manages the installation alone in a confined space, using tension lines to adjust the alignment of the masts within the hull.▶ 5:12
