The general rule is to place your center fin 5 3/4″ from the tail of your board.
The position of the center fin can vary from surfer to surfer. We have included a basic guide within the description of each particular model. This is not etched in stone. Please feel free to experiment. A few general rules are:
- The leading edge of the the center fin usually ends up about even with the trailing edge (at the base) of the of side fins. This is generally a good starting point as well. Depending on what you are feeling, move the center fin up or down the box in 1/8″ increments.
- If you are having trouble finishing out turns and cutbacks, or are not getting up and down the face quickly enough, you should move your fin up approximately 1/8” to 1/4”.
- If you are digging rails, or catching rails in the front 18” to 24” during cutbacks, you should move your fin back approximately 1/8” to 1/4”.
Please understand that these are basic guidelines, and are relative to where you stand on your board, and if you are standing in the right spot according to your style and the type of board you are riding.
