(CNN) For more than eight years, the world sailing speed record has remained unbroken.
In November 2012, Australian Paul Larsen reached 65.45 knots (or 121 kilometers per hour/75 mph) in his Vesta Sailrocket 2 in South Atlantic waters off the coast of Namibia.
However, two rival teams, one in France and one in Switzerland, are now striving relentlessly towards the same goal: to create the fastest sailboat ever built.
One is headed by the former world title holder, and there are two brothers involved but on opposing teams.
Paul Larsen is a sailing speed freak. His Vestas Sailrocket 2 boat broke the world speed sailing record for a mile in 2012: 78.26 mph! What s he up to now?
