Hi Steve,
My Linda and I have admired your evolving burly long legged design philosophy for years. We sail out of Marion, MA on Buzzards Bay with trips up and down the New England Coast.
This year our good friend John Herzog has just acquired “Cloud Nine”, a lovely vintage Allied Seabreeze 35′ yawl, which he will be keeping this year on our helix auger mooring in Marion. The Bay is very open to the SW, and notorious for Hurricane surge. NOAA says this will be a very lively summer as you know.
I have suggested before launching John consider fitting a massive cable attachment point in the stem just above the waterline with added heavy blocking in the chain locker to accept a shackled 1/2″ steel cable or chain storm pennant. Length to the mooring top chain would be set to allow appropriate stretch of the two cafe protected 1″ nylon mooring pennants while applying most of the load to the eye at the waterline. John’s mizzen should help to somewhat reduce tacking on the mooring caused by the lovely sheer of the Seabreeze rail.
I have seen people attaching a steel storm cable to a single eyebolt in the stem, and feel that this may be vulnerable to side loading expected in storm surge.
Do you have any thoughts about such a rig? Have you ever seen a commercial fastener that would be a suitable stem shackle attachment point for a storm cable to secure a 13,400 lb designed displacement vessel, or do we need to have something custom made?
Thanks much and safe cruising,
Bill Bowers,
SV “Iteration”
Hi Bill:
The logic of your idea is sound and reduces angle and load by lowering the attachment point. I would be wary of an eye bolt. A properly engineered tang would be best. I don’t know a stock fitting t o suggest.
