Wind is definitely picking up at Luderitz. It reached 35 knots with stronger gusts exceeding 40knots plus, and more records are expected to be broken in the upcoming speed sailing sessions.

Martin Toth, from Czech Republic, improved yesterday's national record with 44.63 knots. A splendid performance that only proves how committed Europeans are at the moment.

Franz Grabner broke the Austrian national record by driving its windsurfing sail and board at 47.88 knots. The previous mark - 42.78 knots - had been set in 1993 at 42.78 knots.
