What this video covers
Sven Yrvind is constructing a small, shallow-draft boat designed for a 14,000-mile nonstop voyage through the Southern Ocean.▶ 0:16 To ensure a sufficient water supply during the transit, he is building rain-collection boxes integrated with the vessel's booms.▶ 0:29 He laminated the edges of these boxes to increase structural integrity, using nine-millimeter material where six millimeters would have sufficed.▶ 1:47 The project also involves installing hoff bearings, which will be secured using threaded rods because standard screws lack the necessary length.▶ 3:17 During maintenance on an onboard compressor, Yrvind failed to drain the unit regularly, causing it to clog and spray debris when forced open with pliers.▶ 2:26 He subsequently cleaned the compressor and prepared the assembly for the next phase of construction.▶ 3:01 The over-engineered lamination provides significant strength for the water collection system.
