Questions & Answers

Ask a Question
  • Which quantity and degree should I purchase for a standard thruster shortboard

    The degree of cant in the fin box depends on how you want the board to perform.

    Choose 5 degree fin cant for faster, down the line surfing. Choose 9 degree fin cant for more turning ability as the fin pivots quicker at a higher degree.

    You'll need a 0 degree centerfin box too of course for the tri fin set.

    For quad fins choose 9 degree for the front fins and 5 degree or 3 degree for the rear fins depending on your speed vs. turning preference.
