There should be a difference between big boards and smaller boards. Upright fins. 15° . Rake 30° fins. and Weedfins with 45°. 125-140liters with 7m˛-8,5m˛ 36-38cm Slalom or Freeride fin. Rake 30° 32cm is 39cm long - Weedfin 45° 32cm is 45cm long. 105liters-125liters Slalom 30cm-33cmRake or Freeride fin. Rake30° 28cm is 35cm long 7-8,5m˛ Weedfins 45° 28cm is 39cm long 80liters -105liters 27-33cm Slalom or Freeride fin. 6,5-7,5m˛ Rake 30° 25cm is 28cm long Weedfin 45° 24cm is 34cm long. There I work doubleasymm.fins can I use the fins 2-3cm shorter. Carbon or G10? Carbon shorter than G10. So you can see,many points. At first: No spin out and fast.

As a guide the relationship between Sail and fin size is Times 5 add 3 !!!! So for a 7 metre sail;;;; x 5 gives 35cm Adding 3 gives 38cm 7 metre sail (starting point) fin 38cm.. Works pretty much all disciplines !!! AS A GUIDE !!!! Faster you go ; smaller the fin needed.. If you are going like stink on 7 metre on nice flat water you would get away with much smaller fin than marginal powered 7 metre >> If you experience control probs;board trying to lift windward rail try smaller fin. If your mates are going upwind better than you ;try a bigger fin !!! Experiment til you feel comfortable. |

Can someone please explain to me the relationship b/w sail size, wind speed, and fin size? I'm trying to learn about fins and their function (aside from the obvious lateral movement of the board) like tail lift and drag. I know there's a lot of information as far as this goes, i'm just looking for the basics. thank you so much for your help! Eric |
