She was a catamaran and IMO she was a more advanced concept than this trimaran. However they built her to too tight a time schedule and the stresses of high speed in rough waters led to hull failure. She had twin masts which of necessity were unstayed so the twisting effect on the hulls at the bases of the masts must have been enormous. When built she was, I believe, the largest single carbon fibre construction ever made. I am sure the designers of this trimaran thought a lot about 'Team Philips' before coming up with a trimaran with a single mast amidships. This allows the mast to be stayed but the stresses on the crossbeams must still be very great. We will see if she stays in one piece, but if they have built her for the America's Cup she is unlikely to be tested in gale force winds in the open ocean that proved the end of 'Team Philips'. |

TP was either way ahead of her time or just a total disaster but in any case would have been a bust in a course racing event. This boat, "Stradivarius", is more of a development of the ORMA 60' class on the scale of the Groupama 3 which I'm sure they have studied. The canting rig, foils and so on. That is why BMW/Oracle hired Franc Cammas to oversee the project and drive the boat. The 10 foot overhangs are notably different from the ORMA boats and the only bit that has obviously been developed to the DOG. Still, if they have a DOG match the defenders just need to build a faster boat for the location that they choose. It's virtually impossible to win a true deed of gift challenge. -- Tom. |
