The inspiration for this fin comes from forms you encounter at fish, the fins of a humpback whale also have no smooth leading edge. Protuberances, nipples to the leading edge have scientifically proven benefits. Also at windmills is fully experimented with jagged surfaces along the Wicks.
It has a positive effect on resistance and the possible incidence angles (angle-of-attack) which may have a vin in the water, thus many spinouts.


For me it is for the first time in years that I see a really new concept in a wave fin. Speed fins have big forwards with the arrival of Delta fins a gang. Who knows, this jagged front many advantages for wave fins.
I hope the HB Concept: Wave rapid testing.
