Use the following information to narrow your search and help determine which quad set or rear fins will ultimately work for you and your board.
STEP 1: REAR FIN POSITION
Checking your rear fin position allows you to pick the correct quad set or rear fin that will suit your board.
STEP 2: REAR FIN SIZE
The size of the rear fin will have a major influence on the pivot and hold characteristic of your board.
STEP 3: REAR FIN FOILS
Choose a foil that best suits your rear fin position and the desired performance you want to achieve.
Flat: Mimics the performance of a regular side fin, offering fast transitions between turns, quick release and added hold on rail. (Ideal for boards with a wider tail; performance shortboards; and boards with rear fins positioned close to the rail)
70/30 or 80/20: Combines the performance of a centre and side fin, offering increased speed, smooth rail-to-rail transitions and a consistent feel in a variety of conditions. (Ideal for all board types and rear fin placements)
50/50: Mimics the performance of a regular centre fin offering increased pivot with the added advantage of stability and control. (Ideal for all board types and rear fins positioned closer to the stringer)
