Was reading latitude 38 and came across yet another keel failure this time on a J-80.

Here's an excerpt: Latitude 38 Story (LINK)

Latitude 38 said:
Wilhite says he'd been planning to do BAMA's Doublehanded Farallones Race since January. Since he doesn't own a boat on the Bay, he asked his old friend Peter Truce of San Rafael if he could borrow his 1994 J/80 Heat Wave. Truce readily agreed and Wilhite began preparing for the race. "This is a tough race," he said of the nearly 60-mile course around the Farallones and back, "and I never took it lightly." Indeed, he was meticulous in his preparation of Heat Wave and himself, putting together safety gear, working on the boat and recruiting an excellent crewmember.


Wilhite met Dave Servais, 24, while racing on Puget Sound. After Servais moved to San Diego to pursue his goal of being a professional sailor — he's a professional rigger and has taught at J/World — the two kept in touch. When it came time to choose crew for the race, Wilhite immediately contacted Servais, who immediately said yes. "We've only known each other a couple of years," he notes, "but we have really great communication and sail well together."


As noted in the lead story, for most racers, the DHF was a total bust. But a handful held on, including Wilhite and Servais. "I'd spent too much time and money on this race just to bail out," Wilhite said. So the pair stuck it out with a group of five or six other boats until the wind filled in. On the way back from the rocks, Wilhite reports wind in the low-20s with gusts to 30. A little higher than forecast but not dangerous.


"By a little after 8 p.m., we were beam reaching under jib and a reefed main," Wilhite recalls. He noted the waves were 12-14 feet with a fairly long period between, a fact the Coast Guard confirmed, though they put the wind speed closer to 40 knots. "Dave (Servais) was setting us up on a wave, reaching across it, when we heard a whuump," said Wilhite. "The helm turned to slush, the boat slowed and the wave we were shooting broke over us. Then we heard a cracking sound like a tree falling over — that was the sound of the keel ripping off."
The boat immediately turned turtle, submerging the pair, who were tethered to the boat and wearing PFDs. Wilhite had a short tether while Servais was attached with a long tether. Once the boat settled and they popped up, Wilhite realized his tether was keeping him too close to the water so he pulled out the knife he had stowed in his pocket and cut himself free. "It was weird not to be attached to the boat," he said. "Dave was holding onto the rudder and there was nothing else to grab, so I held onto the lifelines underwater. My hands are really cramped and cut up today."


It was then that they noticed why they had flipped — nothing at all was left of the keel. "It ripped off at the root," Wilhite said. "The only thing sticking out of the bottom of the boat was the bilge pump." He says he has no idea why the keel fell off — "It's not something you're prepared for" — saying there was no evidence they'd hit anything. Some wonder if it's possible they hit a large sea mammal that was moving in the same direction, but the question quickly becomes irrelevant when you're holding on for your life in the North Pacific.

Great to hear how it turned out. It sounds like these guys did most everything right. The most important being not panicking and conserving energy. When you see shore it is very tempting to swim but sometimes you are better off scrunching up to convserve heat.

My harness has a shackle with a pull cord that I strung large wooden beads onto so I can find it by feel and release it if needed.

I don't normally wear my handheld vhf when sailing at night but I will now. All our lifejackets have strobes though.

I have never understood the engineering that was applied to the attachment of a fin keel. It is a long and very heavy lever with a very narrow point of attachment.

Tim—

You should add whistles to the PFDs too. Yelling doesn't carry as far or as well as a good whistle. :)

I was amazed at the number of boats in the Vendee Globe that reported damage to keels and rudders after what they believed to be from hitting sea mammals.

Of course in this case it may never be know if they don't recover the boat.

i saw a picture of the first J80 and will post it later BUT it had a TOTAL failure of the sump and ripped off glass the lenth of the keel and about 2' to port and starboard

It just left a huge area of balsa core

Actual info

This was posted by David Servais one of the two guys on board Heat Wave. it was originally posted over on Sailing Anarchy and I have quoted it here. Scary!!

Yes we're both very glad we are ok. It was a very scary experience and I don't wish it on anyone. I was amazed when my buddy (Dave Wilhite) dove under the overturned boat to recover our VHF radio from a sheet bag. That's what saved our lives for sure.
I think I spent about an hour trying to stand on top of the boat leaning against the rudder talking to the coast guard on the VHF and holding a flashlight over my head.
To answer some of your questions -
The keel did fall off. We were going really fast down a very large wave with a reefed main and the jib. All of a sudden I had no helm and the boat turned 90 degrees (very weird thing to have happen when you are going fast and actually a little low - i didn't feel i was in danger of wiping out at that angle and speed at all, we had been doing it for hours). The boat turned 90 very quickly and the wave we were riding broke over us and rolled the boat. At the beginning of the roll we heard what sounded like a tree cracking and falling down. That would have been the keel falling clean off. We were left in the water, teathered to the jack lines under the boat. We ended up cutting our teathers so we didn't get dragged under.
About an hour later and lots of talking on the radio, 2 coast guard boats, a pilot boat and a helicopter all found us at the same time. They tossed us a line and I got my buddy off the boat as he was much colder than me due to the fact that he had been in the water the whole time while I was standing on the boat (though I think i got washed off the boat about 50 times). Then another coast guard boat told me to swim to them so I did.
Neither of us have any serious injuries, just lots of bruises and pretty sore bodies.
The coast guard did a great job of finding us and getting us to safety, lots of thanks go out to them.

Apparently this is the second J-80 keel loss that has been reported..

Seaweed Too

We were surfing off some large swells on a totally black night a few years ago on my Hunter 40.5 during a race (which was spooky enough) and we then hit a big wad of seaweed that stopped us cold with enough G's to bring the bow down and toss my watch off the cockpit seat.

There's an article in today's SF Chronicle (SFGATE.net) on this. But my question about the other keel failure - also to a boat with a similar structure - still stands: True, there may be some incorrect repairs or some fault going uncorrected, but it still seems to me that the actual design - long, narrow keel with small surface area at the point of attachment - makes this type of boat more subject to this catastrophic failure. It still seems to me that underneath it all is design failure.

From what i read about glass losing strenth over time in general and about stress
induced fiberglass fatigue.

It would seem that the J80s may just be wearing out as it does have a good size bulb that has to be flexing the sump

Ross right, you beat ya!

Bolted on keels, sooner later they all fall down.

Try to imagine building a second floor balcony on a house and just bolting it to the reinforced walls with no braces under it.

I would say that is to the extreme Ross. I bet most any production sailboat with a fixed keel could be layed on it's side and host a nice little deck party including BBQ grill and cooler!

If that house and deck were made of FRP, it would be a different story.

If that little deck party started boogying, in step, the wider the point of attachment, the longer it would last.
Those narrow fin keels just represent such long levers that building with steel to such loads and flexing forces would call for large safety factors.

J Boats response to the J/80 keel loss

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. We have few details at this time, so can only make recommendations on the little we do know.

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. Additionally, the keel floors tabbing had delaminated from the interior hull laminate prior to the incident. In other words, a routine inspection or survey by the owner or a service yard could have led to the repairs needed to have prevented such a failure.

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 keel 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.

Excellent response from a reputable builder. Hopefully the execs at Tartan read that.

Just like race cars and motorcycles, a boat that is raced and used hard needs much more attention than those that cruise the bays and lakes. And just like the race cars and motorcycles, a boat like a J boat, which is built primarily as a race vehichle, is built closer to the edge of failure, than a boat not designed to be raced. Going fast has a high price, and part of that price is stringent maintenance. Many years ago, when I was doing the motorcycle short track scene, the entire bike was stripped to the bare frame, on no more than a monthly basis. Usuallly more often than that. Engines were gone through every week. Every part thoroughly checked. If you want to avoid failures of a racing machine, thats what you have to do.
