Andrea Vanhoorne joins Sonntag-Fins

We are happy to announce that Andrea Vanhoorne (BEL26) joined the Sonntag-Fins team in 2014.






Andrea already used our fins in 2013 and had great success getting 3rd in the 2013 IFCA Youth Female Slalom Championship and the best lady at the Volvo Cup Sylt 2013 and 25th overall with very strong male competitors. Besides other excellent results in 2013 she also won the Belgium Championship in Slalom.

We and the complete Sonntag-Fins Team wish Andrea a successful competition season in 2014!

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.

SL-R

A new fin designed for Slalom Racing. Tested and used in PWA and national slalom competitions.


Going in rough conditions, doing the best speed possible downwind and performing fast and controllable jibes are the most remarkable characteristics of the new SL-R.

The fin's physical design requires the construction with high-end carbon types like IMS65 and TeXtreme. These materials are the base for long-term performance and soft but durable fins.

The profile was developed for low drag over a wide range of AoA with robust flow and delayed stalling.

The unique outline in combination with the developed carbon lay-up creates a very rugged base2mid section and a more flexible mid2tip section for controlled bending and just a bit twist keeping the control in critical conditions.

We adjusted the profiles, profile depth, outline, thickness distributions and of course the carbon lay-ups for usage in the three typical slalom board sizes S, M and L. This means that a SL-R of 38 cm length out of the S-mold is different in the above mentioned parameter than a 38 cm SL-R out of the M- or L-mold.

We produce in length, rake and stiffness as requested by our customer.

Available in length of 30 to 51cm in Tuttle and DT.

SL-P_r2

A new fin designed for Slalom Racing on L & XL Slalom Boards. Tested and used in PWA and national slalom competitions.


Coming from the very successful SL-P it is not easy to create a fin that is more universal in all characteristics.

Therefore we focused for the second revision on fins for L & XL Slalom Boards where maximum efficiency of the fin is required supporting competition slalom racers to win races. In the low and medium wind range low drag of the fin is very important to not waste the limited power of the sail.



The fin's characteristic is designed in a way that the performance is excellent on all courses creating a stable board balance in both axis. The more flexible mid2tip section combined with very high torsion stiffness is able to generate enough vertical lift helping to reduce the board's (water-) surface drag.

We followed the concept to increase the base2mid area by designing the base section wider and reducing the mid2tip area so that still enough momentum can be generated.

We adjusted the profiles, profile depth, outline, thickness distributions and of course the carbon lay-ups for usage in the two slalom board sizes L and XL. This means that a SL-P_r2 of 51 cm length out of the L-mold is different in the above mentioned parameter than a 51 cm SL-P_r2 out of the XL-mold.



We produce in length, rake and stiffness as requested by our customer.

Available in length of 44 to 58cm in Deep Tuttle (Tuttle on request).
