Netherlands Slalom Championship 2014 (NK)


At the weekend 18th&19th of October the NK Slalom 2014 was carried out at the Brouwersdam/Zeeland/Netherlands.

Wind was at the first day challenging weak so that just one elimination was possible. Most competitors were on their big slalom gear.


But Sunday the real wind arrived and 3 full eliminations could be done. Outside gusts up to 32knt were measured with challenging lower winds close to the beach.












The level was quite high so that exciting head to head races were offered to the fans on the beach.

Peter Volwater testing GPS_4

In the last two weeks the wind in the Netherlands allowed also testing the smaller equipment for Peter Volwater.

Testing was done with the Starboard iSonic 90, KA-Race 6.3 / 7.1 and our 30cm GPS_4 at the Grevelingenmeer (Herkingen /inside&outside) and also at the Amstelmeer. Good spots for testing conditions in between flat water and solid chop.






At the Amstelmeer Peter did fantastic runs resulting into a new spot record of more than 38knt over 500m in the chop.   Link to www.gps-speedsurfing.com

Only Girls Windsurf Clinic

Sarah Hébert will coach a girls only clinic in the week before Defi-Wind 2014 in Gruissan.

One goal is to get prepared (surfer & equipment) for the conditions that are normally waiting on each surfer at a spot like Gruissan with its strong winds, flat water, sun, salt water and more.

Here you find the key data and more details when following the listed website:


Sonntag-Fins is sponsoring the clinic with our products for the price-giving.

GPS_5 rev3

The GPS_5 is now offered in the 3rd revision.

In 2013 we optimized the profile, outline and thickness distribution for less drag and robustness against stalling/ventilation.

Speeds are excellent and the fin allows easy access to the board's and sail's performance.





We are now able to produce this fin in the range of 180 to 250mm with a standard rake of 30°.

We recommend the usage in speed boards or XS-slalom boards in the range of 40 to 55cm of board-width.
