Speed Fins

Hurricane speed fins are actually based on the weed shapes, but with a regular rake of 30 degrees, of course other rakes are feasible.
Almost all sizes making sense for high speed sailing are possible. 
For personal speed record attempts, an asymmetrical speed fin is available as well. This Asy Fin is also available in a 45 degree version (up to a length, deepness of 27cm).
