A4C Series

The A4C Series is a fin design that Fits into the templates we consider High-Performance For Next-Level Surfing.  We identify our High Performance Fin Range with the colour MANGO

The A4C series has undergone extensive testing before being put into production. This testing process resulted in many refinements and improvements to the series, easily making them the most versatile of the Performance fin series.

This series also has a wide range of sizes. These sizes cover a broad spectrum of fin combos, from twinzers to thrusters.

The A4C is a combination of our original A3 and XPD2 designs. We combined the best of "both worlds" to make the A4 Series  

The shape of this series features a strong cutaway at the base and a reverse curve in the upper portion of the tip, adding more tip area. The trailing edge of the fin is shaped like an "S" in profile of fin. Coupled with the PHAT FOILS, it further enhances the water flow around the fin.

There is much more going on this fin than your typical dolphin "performance" fin, once you try them you will be blown away.

Two of the biggest fins in this series, The A4C-500 and A4C-550 have been modified to use the new BLENDED-WING profile for a more significant performance boost. This type of foiling bends the fin's profile just over halfway up. It allows the tip to be thinned out, improving flex and enhancing the inside foils. This helps maintain speed through turns and add looseness without losing holding power! 

The A4C-500CK KAHI centre fin has also enhanced the versatility of this series. These center fins are a game-changer in a thruster setup, allowing it to feel and behave much more like a quad. 

All the HIGH PERFORMANCE templates in this category are CNC-machined from solid fiberglass and come in a MANGO colour only, except for the BLACK center fins. These include A4c, F8 and the XT2 series of Fin ranges 

The supported fin bases are GEARBOX, DUAL TAB and FUTURES.
