Pic taken off the Vestas Sailrocket website
A friend forwarded this website to me http://www.sailrocket.com/index.htm They are one of the contenders to break the speed record using the wind under sail power. A few weeks ago the record was broken in Namibia, by kitesurfer Robert Douglas, with a speed of 49.85 knots. It's quite an interesting site giving all the info about the team etc. and some good pics too.
