Surfboard fins come in various setups. Some of these configurations include the 1-fin or single fin, the twin fin, the 2+1 fin, and the tri-fin or 3-fin. Each one of these setups offers something unique to your surfing experience.

When a surfboard has 1 fin, it is more adapted for straight shot surfing. Those with 3 fins can be steered more intricately.


A 3-fin surfboard is more stable than a 1-fin surfboard. In surfboards with 1 fin, there are no side fins. The single fin in the center is not balanced out by other fins.

The main differences between 1 fin and 3 fins on a surfboard lie in maneuverability, stability, speed, and versatility.

The 3-fin setup is more maneuverable, stable, and versatile. The 1-fin configuration, offers relatively more speed and slow, smooth turns.
