Phase Five 3D Speed Base Quad Fin Set

3.5"

3D Fins Dimple Technology: Golfballs have dimples because it helps them slice through the air quicker and more efficiently, going further than if they did not have any dimples at all. The dimples on a golf ball reduces airflow drag exponentially. This is the same concept applied to water flowing over surf fins. Dimples = less drag. Water flows without sticking to the fin increasing overall speed and performance.

Wavy Curve Design: The unique curvy design allows the Speed Base Fin to have a wider base which creates more drive and speed, without being so deep inhibiting the board from “breaking loose”. The depth of the Speed Base Fin is relatively shallow when compared to other fins with the same length base. You will notice increased drive and speed while the wavy leading edge surface acts like bigger faster fins, but shallow so it can break free for spins and revert riding.
