Today is the last day of strong wind, co-operative tide, and time... the Luderitz Speed Challenge sees the last of the racing today, with the official closing ceremony tomorrow (Friday).
Today is going to be a huge battle, with the top riders Alex Caizergues (FRA), Rob Douglas (USA) and Sebastien Cattelan (FRA) going all out to get (or keep!) the title of the world's fastest sailor.
The 50 knot barrier has been broken, and now these three riders are separated by only 0.05 knots (50.57, 50.54 and 50.52).
There are also several riders snapping at their heels, just off the 50-knot level, including privateers Jerome Bila and Sylvain Hoceini.
