America's Cup racers have to be as light as possible for performance. Looks like this one was just a bit TOO light. Richard |

Carbon fiber structures are very strong for their weight but are not
noted for graceful failure modes. cavelamb himself wrote: Americas Cub 1995 Australia One http://www.sailingscuttlebutt.com/media/08/0310/ |

On the average, it's only 10% or so stronger than S-fiberglass. Its big advantage over other composites is its stiffness, not its strength. -- Ed Huntress |

After they pulled it out of Jamaica Bay they hauled the wreckage to a lot behind my office in Harrison, NJ and just left it there after the inspection. Eventually it was taken out to somewhere. -- Ed Huntress |

Watch formula one auto racing- when there's a shunt , there's CF shards
thrown all over hell and gone. Why they don't require a kevlar wrap to contain the crap is beyond me though I suspect that the shedding of parts is their way of shedding energy at the same time. BTW the f-1 season starts this week. Despite the past several seasons being about as exciting as watching kudzu grow, I'm still watching...sigh. Pat |

Hamilton is the best thing to happen to F1 since Senna. He deserved the championship, but the FIA penalty would n't let it happen anyway. New this year - Nelson Piquet's kid joins Rosberg's boy. |
