9 Things In Your Bilge That Tell You The Keel Is Coming Off

9 Things In Your Bilge That Tell You The Keel Is Coming Off Since 1984, World Sailing has recorded 72 keel failures on sailing yachts. Twenty four people died in them. In almost every case the keel bolt that failed looked perfectly sound from inside the boat, because stainless steel corrodes fastest in the one section nobody can inspect: the length buried inside the hull laminate, sitting in an oxygen starved sump. This video breaks down the nine warning signs a failing keel leaves in your bilge, and the free two day test that finds the cause instead of the damage. Tea staining under the washers, weeping at the plate washers, unexplained bilge water, crazing at the keel root, detached floors, dull notes under the hammer, distorted resin caps, rust on mild steel washers, and increasing thread above the nut. We cover the Cheeki Rafiki loss of May 2014, where the hull skin at the keel measured 7.7mm against an ISO 12215-9 minimum of 9.1mm and an ABS 1994 guideline that would have demanded 24mm. We cover the Cynthia Woods keel failure of June 2008, where investigators found four documented groundings and no record of any qualified repair. And we cover why a quarter of every recorded keel failure traces back to grounding damage that nobody assessed. Published keel bolt torque figures, bolt material service lives, and the Don Casey jar test are all included, along with the World Sailing Offshore Special Regulation 3.02 inspection requirement that applies to racing yachts and to nobody else. Yachts & Boats covers the marine industry the way the numbers actually read.
