What this video covers

Sven Yrvind installs a prototype sail-furling and water-collection system on his boat, utilizing two side-by-side masts and a smaller third mast aft.▶ 0:28 The entire assembly weighs nine kilograms.▶ 0:22 The furling mechanism operates via a hand crank located near the hatch, allowing for reefing while the operator remains safely positioned.▶ 8:55 Yrvind measures the mast height at approximately 2.4 meters, with 520 centimeters of clearance between the masts, providing enough space to stand on deck.▶ 6:25 To stabilize the system during reefing, he plans to add topping lifts and small ropes to keep the sail assembly close to the masts.▶ 7:19 He identifies a difficulty in removing the masts, which are currently secured with a tight, wedge-like fit similar to a drill press chuck.▶ 9:40 To facilitate future removal, he intends to glue a lever or tab to the base of the masts.▶ 10:20 The current setup remains provisional, requiring further refinement of the halyards and sheeting arrangements.▶ 1:48
