SL-Weed

The SL-Weed was developed as a true weed fin with progressive rake helping to shed off the weed efficiently. The blade is shifted 3 cm in front of the base so that it’s easier to use the standard setting of the board for upright fins. Bending and twist curve are the same as for a slalom fin, so the rider is able to fly the board on the fin.

The sizes of the SL-Weed are adjusted to sail stable and fast with medium slalom or freerace boards (67cm) up to large slalom or freerace boards (85cm).

The fin has a progressive leading edge curve causing shed-off forces that gets higher as more the weed moves downwards in tip direction. We can adjust the rake as requested, but we found very good performance with 40° rake close to the base. At this (base) rake the fin has around 45° rake in middle and 48° 20mm from the tip related to a 360mm (vertical) length.

We use a profile that is based on the very well approved SL-pro design also showing in this new model excellent performance.

The fin creates sufficient vertical lift by just very low amount of geometric twist. The board’s nose position is in a medium position giving good control and not causing a sticky feeling when sailing on very flat water.

The SL-Weed can be produced in sizes of 30 to 36cm with Tuttle base.
