Matt Biolos has created this Keel Quad set for wide tailed alternative boards to give them directional control, while still maintaining maneuverability.
Matt 'Mayhem' Biolos's specialty quad fin set. High area quad keel set adds bite and control to hybrid boards with wide tails, without sacrificing pivoting capabilities.
Open face, down-the-line waves, particularly good in point and reef breaks.
Modern fish and hybrid models with moderate-to-low rocker.
Please Note: this fin is designed to be used exclusively with the FCS II Fin System, and will not fit in the traditional FCS Dual Plug System.
