DYNAFIBER FREEWAVE FIN PB

The Dynafiber Freewave Vinylester Fin is a versatile hybrid fin designed for sailors who want a "do-it-all" setup. It sits perfectly between a pure wave fin (which is very curved) and a freeride fin (which is straighter and faster), making it the ideal choice for bump-and-jump conditions and high-wind blasting.

For the 2025/2026 seasons, this fin is often chosen as the primary single-fin upgrade for modern "Freewave" or "Freemove" boards.

1. The "Freewave" Geometry

The shape is specifically engineered to handle two different worlds:

• Wave Side: The tip has more curve than a freeride fin, which allows the board to turn more easily on a wave face or during a carving jibe.

• Freeride Side: The base is wide and the profile is relatively thick, providing the "lift" and "drive" needed to get the board planing early and to cruise through lulls without losing speed.

• Acceleration: The leading edge is designed for quick acceleration, helping you get up to speed fast enough to hit a ramp for a jump.

2. Vinylester Construction

As with the other Dynafiber fins in this range, Vinylester is used to provide a specific balance of feel and cost:

• Super Rigid yet Flexible: It is stiff enough to hold a high-speed line without the "wobble" of plastic, but it has enough "active flex" in the tip to prevent spin-outs in choppy water.

• High Impact Resistance: Freewave sailing often involves shallow water or rocky entries. Vinylester is incredibly tough and easy to repair with a simple file if you get a "ding."

• Cost Advantage: It offers roughly 90% of the performance of a G10 fin for a significantly lower price (typically around €85–€97).

4. Which Box to Choose?

• Power Box (PB): Usually found on larger Freewave boards (95L–115L) and "Freemove" boards. It uses a single bolt from the top.

• US Box: Often found on smaller, wave-oriented boards. This allows you to move the fin forward (for better turning) or backward (for more speed/stability).
