Hva denne videoen dekker
Sven Yrvind modifies a repurposed spar to serve as a yard for the aft mast of his custom high-latitude, shallow-draft sailboat.▶ 0:04 The sail measures 1.85 square meters, roughly half the size of an Optimist dinghy sail.▶ 2:22 Yrvind drills additional holes into the spar to accommodate a two-line configuration, ensuring the lines wrap securely around the yard while leaving a few centimeters of clearance for material stretch.▶ 4:34 He uses sandpaper to smooth rough surfaces on the spar before finalizing the rigging attachment.▶ 2:54 This yard represents the first of three required for the vessel's multi-spar rig.▶ 3:59 Future construction tasks include developing a rain collection system and furling booms for the planned 14,000-mile nonstop voyage through the Southern Ocean to New Zealand. Proper spacing and line tension on the yard prevent slippage and allow for sail adjustment.
