NOTE: These fins are used.  They show no signs of use, but they have been in the water.


Where AU Fins all started! Fast down the line and reliable through turns. Knee-high to a foot overhead, decent to epic waves, this template has you covered! Enjoy quick speed from the takeoff with spring-loaded transitions up into the lip and through the wave face. Good for power surfing, essential for enhanced barrel riding.



The Original template in 24K & Black Gold constructions have been with the AU Fins family since the very beginning. This template is where it all started, born and raised from the meticulous testing and analysis of 23 prototypes over the course of 2 years. The original series was rigorously put to the test by the inventor of AU Fins in conditions ranging from waist high Huntington Beach to triple overhead G-land and everything in between. Each prototype was thoroughly ridden with the exact same board, examined and improved based upon how the board performed. Our main objective before releasing this new technology into the surfing world was to create a product and a brand that surfers would organically and excitedly tell their friends about! If you feel like the AU Original Series is for you don’t hesitate, better surfing awaits!

Ideal Conditions

This template performs best in conditions ranging from waist high to a couple of feet overhead.

  • Small Surf: You will immediately notice a burst of speed from the take-off with generous amounts of board agility on the open face.
  • Medium Surf: You will notice an even greater feeling of projection in and out of turns compared to what the board felt like before AU Fins. The maneuverability is largely enhanced and feels reliable and consistent.
  • Large Surf: You will notice the board loosen up quite a bit without sacrificing speed or control. This template is a great all-around fin that really excels in 3’-8’ decent to epic waves.

Skill Level

  • Advanced: You will notice the “slingshot” effect off the bottom up into the lip and through carving maneuvers.
  • Intermediate: You will notice easily powering down the line with projection and stability while wrapping through turns.
  • Novice: You will notice a more lively feel to the board with extra energy to give in the critical sections of the wave all while feeling stable and controlled.
