What this video covers
Sven Yrvind rigs a 6-kilogram SPADE anchor on his small plastic boat, working through the chain attachment, a shackle pin riveted flat with a hammer to prevent it backing out, and the rope setup for both anchoring and lifting the hull.▶ 1:46 He replaces the anchor's original ring with a larger welded ring for a more solid connection, then ties the rode with a round turn — two wraps around the ring — for added security.▶ 2:58 The anchor rope is 10 mm polyester with a breaking strength of about 2.8 tonnes.▶ 4:10 He cuts six 6-metre lengths from the same rope to serve double duty: four as lifting slings for hauling the boat and two as anchor rodes for the small and larger anchors.▶ 3:35 He chooses polyester over Dyneema because the stretch distributes load evenly across four lifting points.▶ 4:25 A separate AIS grounding problem opens the segment: the unit requires a protective earth connection, but the boat has no ground plane, and earlier AIS and VHF installations on the same vessel required none.▶ 0:07 He asks viewers for input on whether the grounding requirement is a genuine safety need or boilerplate liability language.▶ 1:32
