Phase 5 3D Speed Base Carbon Wakesurf Fins (Twin or Quad)

In stock

Same great design as the original 3D Speed Base Fin, constructed in full Carbon Fiber for even more performance!

We are very excited to release our first ever wake specific surf style fins.  After hundreds of hours designing and testing, we introduce to you the Phase Five Speed Base Fin.  

Working together with the mastermind Courtney Potter of 3D Fins, the Speed Base Fin was born. There are two main features here that no other fin on this planet will have.

1.  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 reduce 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.

2.  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.

Fin Size: 3.5"


Fits Phase 5 "Surf Style" boards along with any other board with FCS fin boxes. Does not fit on Phase 5 skim style boards.
