Qué cubre este vídeo

Sven Yrvind constructs custom spars for a lug sail rig on his 5.9-meter boat, designed for a 14,000-mile nonstop circumnavigation of the Southern Ocean.▶ 0:14 He reinforces the yards by injecting epoxy into the spar ends to ensure structural integrity.▶ 1:06 To manage rigging attachments, he machines four end fittings on a lathe, drilling 11-millimeter holes for rope attachment points.▶ 3:53 He secures these fittings into the spars using epoxy and protects the lines from resin contamination with shrink tubing.▶ 5:19 During the assembly, he evaluates the placement of water transfer components near the 30-millimeter transom to avoid interference with the 28-centimeter tiller movement.▶ 1:44 The process reflects a transition from traditional materials like hemp and cotton used in the 1960s to modern synthetic fibers and epoxy resins.▶ 6:12
