Check out Anders Bringdal touching 50-knots on the Namibian speedstrip at the 2011 Luderitz Speed Challenge.
3 November 2011: The wind lived up to the incredible forecast blew super strong on Monday (up to 55 knots), this created too much chop towards the end of the course though, so it was difficult to record fast speeds.
Tuesday was better despite there being less wind as the water state was flatter. So a lot of lessons were learnt and action is being taken to correct this. More news to follow soon at www.luderitz-speed.com
