Results of active stray current passing through keel (in marina) to stainless steel nuts in bilge.
Moderate osmotic blistering of fiberglass hull.
Improper and dangerous forestay chain plate assembly.
Forestay pad eye design did not “spread the load”. High wind load on head sail over stressed this weld (poor weld joint design) tearing the top of the weld and leading to crack propagation down the sides.
7×19 Wire (7 bundles of 19 strands each) is used for flexibility. One broken strand soon leads to another. Time to replace both steering cables. Use Grade 316 Stainless Steel.
Consumer grade copper, acid cored lead solder and saltwater lead to this failure. Flooding was countered by bilge pumps until batteries died. This assembly is easily and safely replaced with marine grade plastic fittings.
Moderately heavy weather and rigging failures required this mast to be cut away while offshore. Annual (or more frequent) rig inspections are essential.
Whether due to a flaw in laminate or leaks at fittings (fastener holes) soon
leads to degraded coring and soft decks.
Survey revealed this cracked high pressure hydraulic fitting. Located opposite the exhaust manifold of high speed pleasure craft. Catastrophic failure of the fitting could result in spraying the hot exhaust manifold with oil resulting in a flash fire at 70 mph.
One of several nuts found cracked during inspection for insurance. Annual (or more frequent) inspections are essential.
3/16″ (4.7mm) thick stainless steel plate installed to back up deck cleat
Improper installation of hose clamps – use proper size clamps (minimum tail) and
rotate clamps so ends are protected. Never turn ends out – as shown.
Sequence Correct ! Small nut first then the heavy nut.
This hose has reached end of life and should be replaced.
Ideally, The Chain Plate Should Be Angled Forward EliminatingThe Need For Transition Plates. Chain Plate Needs. Re-bedding.
