Asymmetric by design, these fins feature different foil on the inside and outside to enhance performance at twin tip speeds.
The outer foil is longer, forcing water to travel farther – this creates lift toward the edge of the board that's in the water, helping the rail dig in and hold more effectively. Unlike flat-sided fins, the inner foil is also shaped, improving grip and control specifically at twin tip riding speeds.
The asymmetric profile also loosens the board’s feel, making it turn more like a surfboard. Directional placement is essential – each fin is marked with a “this side out” print to ensure the correct orientation toward the edge of the board. Includes washers.
