I know this is a 'power' forum, but it also is a 'multihull' one as well. So please excuse this digression: Frenchman Francis Joyon in his trimaran IDEC has just set a new world record for the fastest solo 'downhill' time around the world, besting British Ellen MacArthur's record by an amazing 14 days. Here, Adam Turinas compares Joyon's feat with the that achieved by the much venerated Robin Knox-Johnston when he set the first record of a solo round the world journey in Suhaili <http://www.boatdesign.net/forums/showthread.php?p=182336> There is a fascinating paradox. Sailing is one of the oldest forms of transport but has evolved so much in 40 years that boats can travel long distance 400-500% faster. Is there any other form of transportation that has evolved as much? There were fast cars, jet planes, space rockets, motorbikes in 1968. No doubt they perform better now than they did in 1968, but 5 times better? No way! God I love sailing!
