North release the 2018 S_TYPE SL telling us – “The S_TYPE SL has won numerous world-wide magazine tests over the years and received first-class honours in their categories. Therefore Kai Hopf has thrown everything into the mix, resulting in even more
performance without having a negative effect on the handling. The decisive factor is the NO.COMPROMISE.
DESIGN that he translated directly from the WARP F2018 into the S_TYPE SL. The outcome is a deeper profile with reduced loose leech and reduced luff curve which all leads to a superior low end acceleration.
Thanks to reinforcements around the leading edge, the known draft stability and the broad wind range could be retained. The result is a highly sporty and competitive slalom sail that thirsts for speed, yet
is easy to tame.”
