I have been waiting for the vertical fins tendency to be "the standard" but it seems angled fins is still the option for some racers/brands.
Can anyone help me understanding why?
My bet on straight fins is:
1) Either you have several boards or you will want to change fin size/design. With angled fins, any change in fin size will break the ballance upwind and, even more, downwind. Does this make sense?
2) Riding with angled board might be a advantage upwind, and in that case it makes sense to use angled fins. But doesn't angled fins create instability when riding fast downwind?
Can anyone with kitesurf racing experience help?
I have little experience kitesurf racing, my race addiction comes from several years of windsurf formula racing.
My personall opinion is that the more angle you have the better it is for light wind (6- 12 knots max)
The stronger the wind the straighter fins you need-so you have more controll & speed at high winds .
But NOT totally straight ones.
I dont believe there is ONE solution. You have to choose wizely - depending on the conditions (also water condition-wave chop or flat).
Personally i am 72 kilos -1.78 and i like to use 22-25 cm angled front and 15cm back untill 15 knots - for sure.
The point is if you have the physicall condition to support angled-big fins with your legs !!!
Its... pain to race 3 or 4 races in a day with big fins so maybe a bit smaller ones is better to take the most out of them cause you will race a bit more comfortable.
My personall view...
