Hanalei XTC450c Centre Fin Gearbox Base

The XTC range currently consists of wide range of template sizes, the centre fin - shown here, have been the most heavily used and tested in Hawaiian winter swells.

The primary driving force behind the design of these fins is to deliver a template that behaves more like a wing than your typical "dolphin fin" style surfboard fin. The motivation for this design all started from the design of a tail wing for a foil board.

Due to their very upright nature, they turn extremely well without loss of speed through the turns. The tips play a crucial role in the turning process as they allow for transitioning of the fin during a turn. This means as the board is placed further on it's rail the tip of the fin becomes more vertical in the water allow it to create a pivot point. Hard to describe but something that can be easily felt when using the fins.

 When coupled with XTC500 this centre fin works really well, 

For thrusters two combinations can be created with the XTC-413 / XTC450C for a smaller looser setup and the XTC-500 / XTC-450C combo for a lot more drive and hold. Due to the shape of the center fin it has a lot of hold when positioned further forward while still providing great turning ability due to the more upright nature of the body of the fin.

These fins have been ridden in boards ranging from small fishes and kneeboards, through guns to tow boards. They have been successfully surfed in everything from 3' slop to 40' faces. They work!
