What if on the race course there are patches of weeds that could cost you the race?
Has someone addressed that annoying problem?
Not sure I understand what you mean ?
Every decent racekiter here has at least one set of "weed" fins - in order to compete when it gets problematic with the straight ones.
Raked 30 or 45 degree backwards at the LE
But they will NEVER be high performance, because of the sweep.
Although, made stiff and thin and with carbon of course, in order to be competitive
They will win the race though, if the conditions are gnarly regarding sea weed
And for freeriders the good weed fins are a must IMO, I ride more with these than without
The big problem is availability - really hard to find, as there are so many different box types - and also different sizes and profiles etc, so a nightmare for the brands to make, and with really little sale
