Alinghi 5

The Alinghi 5, the catamaran, with the Team Alinghi in the 33rd America 's Cup against the United States was defeated 17.

The catamaran was built by Alinghi Villeneuve and Décision Corsier in an assembly hall in Villeneuve VD. Naval architect Rolf Vrolijk and were the design team Alinghi. At times, Nigel Irens, Benoît Cabaret and Alain Gautier were hired as a consultant. Design coordinator was the Australian Grant Simmer.

The boat was brought for the first time on July 8, 2009 at Lake Geneva with a Mil -Mi -26 helicopters to water. With the same helicopter Catamaran on 7 August 2009 was promoted over the Great St Bernard Pass to Genoa.

The boat is extremely light for its size - a yacht of 10 meters in length should weigh 700 kg at equal ratios and would have 120 square feet of sail area - and optimized for high speeds with light winds and a maximum of 50 -foot waves. Even at about 8 knots of wind the windward hull out of the water. On the Cross more than 30 nodes can be reached more than 20 knots, to room rates. Although the America's Cup regattas only to wind force 4 and 15 kn (28 km / h) wind speed to be sailed, the apparent wind on deck reaches quite 40 kn (74 km / h) or more, which then corresponds to Beaufort 8-9 ( with ungerefften sailing).

Even with technical data, provided the source is estimated by most journalists as team Alinghi, as well as the counterparty BMW Oracle Racing 90, the exact values ​​for competitive reasons and to avoid protests and litigation holds secret. Besides the two lengths of the water line ( 90 or 110 feet, 27.45 or 33.55 m), the subject of official surveying or a dispute had already been decided, is not confirmed technical information. How volatile is the information situation, demonstrated by the fact that rumors about the manufacturing process or location of parts of the sail of Alinghi 5 has already led to a protest and a lawsuit. Would a team - directly or in hindsight - published data, this would have to be given the competition situation anyway critically.
