For an 85 liter board:

  • 14.5 & 10cm for best sideshore wave performance
  • 15.5 & 9cm for best all around performance
  • 16.5 & 8cm for more onshore/backside/bump & jump performance
  • choose the onshore option if you also plan on sailing sometimes as a twin
  • please specify fin box type in the comments of your order (US, Slot Box, Mini Tuttle)
  • Some configurations will be special ordered and take 1-2 weeks for delivery

Please note, other configurations can be ordered/substituted

  • X-Twin-S and X-Quad-S swept fins for weedy conditions
  • Twin instead of X-Twin in the main fins for more power/grip
