    Strange, she carries the same sail number as a McConachy 38 by the name of Carbonado.

    I think it's going to cost a bit more than 35k to enter....

    Aberdeen Asset Mangements share price will hopefully rocket as well on the back of this news......

    Olympic swimmers are some of the tallest athletes in the games....their weights aren't representative for a sport where height doesn't provide a speed advantage.

    James, we are indebted to you for a decent technical update of events over night. I would recommend the official Volvo site entice you with some folded wedge and get you signed up!

    Just heard that he's been found. Zbigniew Gutkowski tells us: "After the media action seeking the lost sailor, was found near the Azores! Thank God he is alive and goes towards Brest."

    Thanks Tim. Unfortunately there is a danger that both the VOR and IMOCA 60 classes may go one design, which will mean there is no offshore development class apart from the Multi50 and the Minis... This cannot be good for the sport in the long run.

    Excellent article James, it's great to get detailed factual information about the different breakages without the sensationalism. It will be very interesting to see what they do for the next race. Let's hope they can get more teams on the start line.

    Juan, every body takes thier hat off to you for the job you have done in this and the last 2 Volvos. Dont blow it. By anyones book having to slow down becaues the hull is delaminating when nothing but water has been hit IS a structural issue. Sandersons story on this website quotes the same problems with the ABN boats. It does not take anything away from your team, when the limits are pushed something has to give at some stage.

    In response to: Jury rig to Itajai
    Excellent article, its good to read first hand information after so many PR text saying the same everywhere.

    I had to mentally add a lot of punctuation to unscramble that first paragraph!!

    Who said the Americas Cup had to be in slow boats?

    How does this stack up with Juan K's comment about a tactical pit stop?

    Thanks for your comments. Fatigue is certainly an issue and one I should have mentioned. I first remember John Shuttleworth bringing this up with regard to carbon structures on his trimaran designs back in the early 1980s...

    Fascinating article, no doubt prompting plenty of armchair reaction. Here's another I'm afraid. I've used over expanded Nomex in areas of high curvature in multihull hulls and have had failures, and now think it has no place in offshore hulls due to reduced sheer properties in the expanded plane. I'm not a great fan of nomex in any carbon offshore hull as we found to our cost in early multihull carbon structures. The structural package is just far too brittle and unforgiving. The V70 hulls could be made far more durable by banning honeycombe cores and instigating a minimum core sheer value without detriment to the yachts performance. Perhaps it would add 400kg to the hull weight, but so what? It would be the same for all. We can cope with rudders and rigs failing, but I thought the days of chopping up bunks was history. Its unfair to blame the crews as they have no idea where the design limit resides - nor do the designers as who knows what wave awaits them in the dark?

    Hi, great article! I am an engineering student at University in the UK. Thinking about these breakages, and also other failures, such as the mast of Jeremie Beyou's IMOCA 60, and I was wondering why nobody seems to mention fatigue? Recently I was shown a variety of failed components none of which had failed whilst under an excessive load. A large load, or series of, had been experienced by the component at some point during its operational life causing damage to the component structure which lead to its failure much later when under a far lesser load. Clearly the use of ultra sound and x-rays to try and check the composite structure for cracks aims to identify such internal damage before failure occurs. However, the pattern of events seems similar. The Volvo race has been very tough on the boats, a large percentage of the course has been upwind with repeated rough sections resulting in repeated heavy loading. Is it really a surprise that the boat's structure is tired? Thinking again about Jeremie Beyou's mast, how often does a component fail and in the following write up we hear how much the component has already endured. As Jeremie commented 'This mast had sailed around the world already and was very solid'. Some failures, such as Puma's dismasting in leg 1, are not caused by fatigue, but by other factors, such as an error in construction. However, I would like to know why fatigue has not been mentioned, when the Volvo failures seem to have all the history that you might expect to lead to a fatigue failure.
