The reality for many of the local venues is seaweed. In such circumstances it’s essential to have a fin that sheds weed, yet still lets you unleash the potential of the flat water and wind available.
CONVENTIONAL WEED FIN DESIGNS
With straight leading edge weed fins, the rake has to be set for the span-wise flow to pull seaweed along the leading edge to the tip. This causes the lifting surface in the tip to be located a long way behind the centre of rotation of the board (trim axis). This is not really a problem deep off the wind with short speed fins, but as you go larger the problem becomes worse. In the end, the straight leading edge is a big compromise in balance. Upwind or across the wind, where the centre of pressure of the fin is too far back for optimal balance with the rig, is where you notice this the most.
TYPES OF SEAWEED
There are many types of seaweed, and the ability of a fin to successfully shed these different types of weed very much depends on the fin design, as well as local variables. Some weed is heavier and more abrasive, and requires a greater angle for successful shedding.
WEEDSPEED VS SUPERWEED
Besides our regular WeedSpeed fins, we have added the SuperWeed to our range for special use in those areas where extreme “sticky” weed growth occurs and our regular Weed fin does not quite cut it anymore … The SuperWeed’s rake is set up at a more extreme angle than the WeedSpeed to shed weed. It does have a straighter leading edge due to the need to keep the centre of pressure as far forward as possible, whilst maintaining an increased minimum rake angle at the head.
