Fins Selector

This fin selector has been developed to help users choosing the right fin length depending on the sail size and type of board they use.

The maximal board width being the value considered to suggest different fin lengths.
These tables were developed for slalom, race and free ride fins and consider the evolution of these different disciplines in the last two years.

The choice of the fin length depends on your sailing style and on your personal preferences. Do you like to sail over or under powered? Is the wind consistent or gusty ? Do you wish to have good upwind performances? All these parameters are influencing the ideal fin size.

Intermediary fin sizes are recommended as multipurpose lengths (Red digits).

The fin length we specify is valid for both freeride and slalom fins. Freeride fins are more easily kept under control and easier to jibe, whereas slalom race fins bring more support and have a greater speed potential.

The maximal width being the value considered to suggest different lengths.

These tables were developed for Slalom, Race and FreeRide fins, and consider the evolution of practices in the last two years.
Technical developments on 2009 floats are quite minimal, and our offer will remain quite logical for years to come.

When you sail, and depending on your sensations... 

You must choose a longer fin when :

  • You have difficulties changing direction while maintaining a good speed
  • You have difficulties starting planing 
  • Your speed immediately decreases in an air pocket 
  • The board  tend to slide leewards 
  • You have a hard time riding on the fin without spinning out 
  • You feel as if the board is sticking to the water  

You must choose a shorter fin when :

  • Your board wants to go  windward and you have a hard time falling off  
  • The board tends too lift out of the water  
  • You have difficulties controlling the board in a balanced way
  • You have difficulties initiating and controlling a jibe as the board keeps to much going straight forward.
