Weed Speed 50º

Black Project



The WEEDspeed (50 degrees) windsurfing slalom and speed fin deals with the problem of thick weed and shallow water while racing or speed sailing. Following on from the success of the original WeedSpeed (now renamed WeedSpeed40) the new WeedSpeed50 is the latest addition to our windsurfing weed fin range taking shallow and weed filled water sailing to new places. Interesting things happen when you increase the angle of the leading edge and Tom has been innovative in his foiling and outline to develop a weed fin with extreme rake yet one that feels like a normal upright fin. To keep the center of effort correctly balanced the foil has been moved forward on the base to allow for increased rake. The WeedSpeed50 features our proprietary Equivalent Sizing System (ESS) which makes it easy for riders to select the correct size. The smaller sizes have been optimized for speed sailing in shallow water while the bigger sizes have been tuned for slalom sailing.

The first thing that you will notice about the WeedSpeed50 is that it sails just like an upright windsurf fin, our aim is to have a seamless transition between the fins in your quiver, and fins should be forgettable so that you can concentrate on finding the fastest path through the often confused waters. Longevity is extremely important to us and hence all of our weed fins feature a robust tip outline to safeguard against accidental damage in shallow water.
