This year’s edition has been tweaked and tuned based on Koster’s feedback. Increased luff curve adds skin tension to hold the profile forward and low to maximise wind range. The control-oriented geometry sets the rake angles to maintain downforce at the mast base whilst setting the clew below shoulder height where it can be most easily managed. Stance is balanced with the upper shaping moved forward to put less pressure on the back leg and reduce fin load.
The HyperSpider membrane consists entirely of high-tech fibres: Technora for the body fibre, and now Dyneema for the X-Ply to increase strength. The pinnacle of windsurf sail materials.
