Hanalei A4C 450 Twin Small Size 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 450 size is intended to be used as a small side fin in a thruster setup, combined with the A4C-500CK center fin. Ideal size for a grom thruster setup or where smaller side fins are preferred.
