    34th AC--Design---Mike Drummond

    Excellent interview:

    http://catsailingnews.blogspot.com/2011/02/ac45-by-mike-drummond-oracle-racing.html

    excerpt:

    CSN: The AC45 is the latest expression on cats hulls refinements, that are converging on a similar shape on racing beachcats and now on the bigger AC cats, Wings are providing sail power efficiency, so which is the next step (if any) in multihull design in your opinion?
    ---
    [MD] Multihulls are very efficient in light – moderate winds, but at high speeds they are limited by their long thin hulls. Hydrofoils or planing hulls are directions to try, but at present they have tradeoffs in righting moment or low speed drag.
    I’m sure there will be incremental improvements as a greater number of designers and sailors get into cats, because of general design evolution. Any time a new material arrives that is lighter, there will be a step improvement in performance through hydrofoils or thinner appendages too.

    34th AC- the challengers-France

    This is really cool-from Scuttlebutt Europe:

    Energy Team, Official Challenger for the 34th America's Cup

    Energy Team has officially become Challenger for the 34th America's Cup. Launched and run by Loick and Bruno Peyron, this challenge is backed by the prestigious Yacht Club de France. The construction of the first AC72 multihull will begin at the Multiplast yard in Vannes on the 1st September.

    Within a month of the official announcement last September that the America's Cup was to be raced aboard multihulls, the Peyron brothers announced that they wanted to bring French know-how together to set up a Challenge to attempt to win the prestigious trophy. That is exactly what they have now achieved. Energy Team, the new French challenge set up around Bruno and Loick Peyron, has been officially registered for the 34th America's Cup since 27th January 2011. It has become the sixth Challenger aiming to grab the silver ewer.

    Energy Team has signed an exclusive partnership with Multiplast, the boatyard based in Vannes (Brittany), which is one of the international references in the world of multihull construction (Orange I and II, Groupama 3). The Multiplast yard will be reserved for Energy Team. The construction of the first AC72 catamaran will begin on 1st September with her launch planned for April 2012. Yann Penfornis, managing director of the yard, will be coordinating the AC 72 design and construction teams, under the supervision of Loick Peyron.

    The first AC 45, the little sister to the AC 72, will be delivered to Energy Team in March 2011, so they may begin training in Auckland.

    The core members of the Racing Team are already in place and bring together a wealth of experience in four major areas that are vital for performance. The core members so far appointed include the following:


    Loick Peyron, skipper of the AC45 and AC72: 6 times F60 world champion, 8 times F28 Trophy Champion winner,

    Bruno Peyron: 8 times world ocean records champion, skipper of the G Class, which will be the ambassador for Energy Team,

    Yann Guichard: helmsman with Loick Peyron : Extreme 40 world number 2, Member of the French Olympic team,

    Thierry Fouchier: performance team, the only Frenchman to have won the America's Cup with BMW Oracle Racing aboard which he was the wing sail trimmer.

    Jean-Christophe Mourniac: performance team, member of the French Olympic team, one of the world's top 5 Tornado and F18 racers over the past ten years.

    Yves Loday: coach for young talent. Former member of the French Olympic team, he was Tornado gold medallist in Barcelona in 1992. He will be joining the team to prepare the "Youth America's Cup" that the American Defender is launching.

    Couple of comments from Paul Cayard that are worth contemplation, from Sail World:
    Commenting on the cat’s tacking and acceleration, Cayard said he was impressed by how nimble it was. 'It is certainly no slower than any monohull through the tacks,' he commented.
    For much of the long upwind sessions, the Artemis Racing team dropped the headsail and sailed under the wing alone. 'We found that it was actually faster upwind without the headsail,' Cayard noted, 'and we were probably able to point a bit higher as well.'
