On Wednesday Zara Davis set a new mark of 44.19 knots/h in the Luderitz speed strip (to be approved officially). By that the old female Windsurfing World Record (by Karin Jaggi) is history by nearly 3 knots/h more. Winds in the range of 28-35knt/h were enough to set the new record.
Congratulations to Zara from the Sonntag-Fins Team for this outstanding performance!
Zara was going with a series Mistral Speed 42, a 5.5 m² Simmer Sails SCR 2012 and a Sonntag GPS_5 rev2 20 cm speedfin.
Here you can see the set of GPS_5 rev2 speed fins (18, 20, 23cm) Zara received for the 2012 Lüderitz Speed event:
Some words over the GPS_5 rev2:
The GPS_5 rev2 is an optimized GPS_5 fin with a new profile and slightly adjusted outline. We optimized the profile for lowest drag on small AoA and delayed cavitation by a nice flat pressure distribution along the chord. The mould size was increased to allow also the production up to 25cm long GPS_5 rev2 fins. This model meanwhile proofed the performance requirements so that we released the design for series production.

“One of the most
challenging tasks we as windsurfer have is finding the right screw length for a
given board&fin combination.”
Looking cross different fin and board manufacturer you find no standards. So when changing to a new board or fin we recognize very often that we don’t have the right screws in our bags. If the screw is too long the fin can be damaged or if too short the screw can get lost during surfing.
So we thought about a solution and designed our own fin screw (or bold) case with several screw length included. We switched to Allen-key screws (often called “Inbus” or better “Innensechskant” screw in Germany) for easier handling when changing the fin at the beach (many sails are using the same Allen-key dimension for the batten tensioners and often have a small Allen-key as part of the sail).
The screws and washers are made of stainless steel, the case is made of a robust plastic and the inlay of a CNC-milled medium stiff foam that does not suck humidity or water. One side of the case is equipped with a fin bolt chart describing the screw length and position inside the case. Of course one T-handle Allen-key is part of the “Fin-Screw-Case”.
Common to our fins the Fin-Screw-Case can be simply ordered by e-mail.

Sarah Hébert arrived in Saint Francois, Guadeloupe, 12 March 2012.
Sarah had to surf in very difficult conditions with very (too) broad wind direction and difficult swell & chop. Due to anemia, she got after several days, she had to rest more and more and finally had to stop the crossing on the windsurf board to start the recovering process on board of the boat following.
In our opinion it was the absolutely right decision to stop the crossing and not risk health or life.
We wish Sarah all the best,
Alexandra & Joerg
