Every 4 years the R du R is raced from St.Malo, France to Pointe a Pitre in the French West Indies, a trip of 3,500 miles. The big multihulls sail this in 7 and a half days, averaging almost 20 knots! There is a real mix of boats, from 40' upwards. Last time the first and second boats crossed the line only 25 minutes apart. The website is mostly in French but still interesting. http://www.routedurhum-labanquepostale.com/en/s02_course/s02p04_historique_2006.php
