I don't know how many saw the story about the Texas A&M race boat that lost its keel and flipped, trapping one crew member and putting the rest in the water for 26 hours until they were rescued. HISTORY OF KEEL CONCERNS SURROUNDING THE CYNTHIA WOODS The Texas A&M University-Galveston sailboat that capsized last week when its keel fell off had been drydocked for keel repairs in 2007 after running aground. The vessel, christened Cynthia Woods, lost its keel on the night of June 6 not long after the start of a race from Galveston to Veracruz, Mexico. The crew was thrown into the water, and one of them, safety officer Roger Stone, drowned while getting two student sailors to safety. The five survivors floated in the Gulf of Mexico for 26 hours before being rescued by the Coast Guard. Though Texas A&M's investigation into the incident is in its early stages, those familiar with the vessel's design, construction and repair history are offering their opinions on what may have gone wrong. Here are some excerpts: * It could be related to an earlier grounding that required the keel to be pulled off, with bolts that had come loose to be tightened at Galveston Yacht Service. Company owner Herschel Payne said the keel was reattached properly but that he did not particularly care for the bolt arrangement or the interior supporting structure of the 38-foot racing boat. * Peter Ross, the man who built much of the prototype for the Cynthia Woods, said that several years ago he warned the company that produced it about a poor keel design that could result in catastrophic failure. Ross, a custom boat builder living in Rhode Island, said he thought the keel was too big and heavy for its "footprint" and had doubts about the methods used to ensure the rigidity of the structure. * The president of Cape Fear Yacht Works, Kent Mitchell, said the boat should have lasted 20 years with no major problems. Mitchell said he discarded Ross’ concerns as he did not have the engineering expertise to know what he was talking about and was not even referring specifically to the Cynthia Woods. Naval architect Bruce Marek, who was responsible for the final design, stands by the keel that was chosen and the process used to secure it to the hull. -- Houston Chronicle, full story: http://www.chron.com/disp/story.mpl/metropolitan/5837037.html I'll take 40-year-old Cals, thank you.

My Cal 20 is 41 years old and has a bolt-on keel that's still bolted on after all these years. There are certain things we expect from our boats, and one of the most basic is that the essential elements will remain intact if properly maintained. That includes the keel, rudder, rigging, spars. Disposable keels may be OK on little inland lakes where you can swim to shore or get help from a passing water skier, but not in any waters where you're depending on the boat for your safety.
