How to Choose Surfboard Fins

Start by confirming your board’s fin-box system and compatible configuration. FCS and Futures fins are not interchangeable, while many longboards use a traditional center fin box with optional side bites.

Fin Configuration and Board Type

  • Thruster: Balanced control, drive and maneuverability.
  • Quad: Fast and responsive, with added hold through turns.
  • Twin fin: Loose, fast and well suited to many fish and retro shapes.
  • Single fin: Smooth, flowing performance for longboards and traditional shapes.
  • 2+1: A versatile longboard setup using a center fin with smaller side fins.

Fin Size and Construction

Fin size should reflect your weight, board design, wave conditions and preferred feel. Larger fins generally provide more hold and stability, while smaller fins can feel looser and easier to turn. Fin template, flex and construction also affect speed, control and responsiveness.
