Ce que couvre cette vidéo
Anchor swivels frequently introduce structural failure risks by creating leverage points that are susceptible to side-loading, particularly when attached directly to an anchor shank.▶ 2:44 While marketed to prevent chain twist and assist with anchor self-righting, these devices often fail to rotate until multiple chain twists have already accumulated.▶ 1:56 Most chain twisting results from rapid windlass retrieval rather than vessel movement at anchor, and can be mitigated by slowing the retrieval process.▶ 2:13 Stainless steel swivels are prone to brittle, sudden failure without warning, whereas galvanized components typically show visible signs of degradation.▶ 3:16 If a swivel is necessary for specific conditions like constant current reversals or poor bow roller geometry, sailors should oversize the hardware, avoid unrated mystery metals, and mount the swivel away from the anchor shank to minimize leverage.▶ 5:37 Regular disassembly and inspection are required to detect crevice corrosion and pin deformation.▶ 4:28 Simplicity in ground tackle design remains the most reliable approach for most cruising sailors.▶ 6:03
