J Boats Responds to Farralones Incident

INSPECT YOUR KEELS
A Notice to J/80 and all J/Boat Owners from J Boats
We learned this morning that a 1994 J/80, racing offshore in a rough Double-handed Farralones Race off San Francisco lost its keel about 8 miles from the finish. Thankfully, both crewmembers were safely rescued by the Coast Guard.

In the absence of a specific incident such as a collision, hard grounding or drop from a crane, a failure of this kind is highly unusual without some kind of warning sign. In the only other keel loss incident among 1,150 J/80s worldwide, the composites surveyor judged the boat to have had significant longitudinal crazing visible at the exterior hull fairbody/ keel sump juncture that predated the failure by a substantial period of time.

No sailboat is going to last forever without some updating and repairs, particularly if campaigned hard. We do not know what factors over its 15 year life may have led to the failure on J/80 hull #45. But we strongly urge all J/80 owners, indeed all J/Boat owners, to routinely inspect keel stringers and keel sump areas, both internally and externally with frequency and most importantly prior to entering an offshore race. Owners should specifically look for any longitudinal (fore/aft) cracking that appears on the outside of the hull and/or on the turn of the bilge, as well as any issues with the fiberglass tabbing attaching the stringers to the hull. Any compromise to the stringer tabbing, due to any number of reasons, can severely weaken the overall sump system. If you find cracks, do not assume that it’s OK, without confirmation from an expert surveyor.

For all boat owners, the keel sump and stringers, along with other high stress areas, such as rigging attachments, chainplates, rudder pintles, mast step, mast partners and primary bulkheads should be inspected at least once per year. As this unfortunate incident reminds us, one can not be too vigilant. Pro-active inspection of the key structural elements of the boat are part of keeping oneself, family and crew safe.

Owners should contact their local J representative if they need assistance.
