Racing or wave boards ?
Big differences there
Raceboards only of course (as this is a raceboard/kite forum)
I know generally what the differences are between the setups and control/performance - but curious what is used in competitions around the world nowadays - in what conditions ?
Although - I suspect that 3 is used even where 4 would work - simply because "knowing your gear" is the most essential, and 3 has many control advantages.
Not too sure we will ever see a "one deep fin" raceboard that works best ?
As a kitesurf board is extremely different from windsurf, because there is no mast foot pressure and control/leverage this way - so the more forward fins are actually to give this control and "no-bouncing", and to stop too extreme fin torque
I dont know - we might get there, but not sure we will end up with a one fin raceboard.
Time will tell
