LEWMAR WINDLASS FAILED - HOW and WHY?!

What this video covers
The Lewmar V5 2000-watt windlass on SV Cordelia, a Venus 46 ketch, failed after 13 years of service while anchored off Soper's Hole, Tortola, in the British Virgin Islands.▶ 2:15 The motor spun but the gypsy and drum did not turn.▶ 1:57 Steve spent four days extracting the gearbox — a stainless-steel-to-aluminium bond had seized the assembly — before discovering the worm-drive gear teeth had completely stripped.▶ 5:24 A failed internal seal had allowed water, mud, and chain silt inside the gearbox, where it acted as grinding paste and destroyed the gears over time; a rusted-away circlip confirmed prolonged water ingress.▶ 10:16 The keyway Steve had hoped to replace with spare keystock was irrelevant — nothing remained to repair or bodge.▶ 10:41 Lewmar UK provided little help sourcing parts; a replacement motor-gearbox assembly was eventually located through a company called Cactus Navigation and ordered duty-free into St. Martin.▶ 11:35 With the windlass dead, Steve manually winched 40 metres of chain and a 40-kg Rocna anchor aboard using a mast-mounted Anderson winch, with Annette and Gus managing lines and the boat drifting into the fairway during the operation.▶ 14:37 The practical lesson: even a well-maintained windlass can suffer catastrophic internal gear wear if its seals fail and chain mud enters the gearbox undetected.
