Hanalei A4C 425 Quad Rears Futures Base
The A4C series has undergone extensive testing before being put into production. This testing process resulted in a lot of refinements and improvements to the series easily making them the most versatile fins in our range.
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 to better control the water flow off the trailing edge of the fin. When coupled with the PHAT FOILS it further enhances the water flow on and off the fin.
The smallest fin in this series. Intended for use as the QUAD REARS in a Quad setup.
height: 4.25" [127mm]
