The FCS II Carver PG Thruster Surfboard Fin Set delivers exactly what it promises, a fin for long, drawn-out, powerful carves. Recommended for boards with deep concaves and moderate-to-extreme rocker the FCS II Carver PG Thruster Surfboard Fin Set is ideal for open faced, down-the-line waves, particularly good in point and reef breaks. With an elongated fin for performing long arc turns the FCS II Carver PG Thruster Surfboard Fin Set is designed with a high degree of sweep angle which provides exceptional control off the bottom and when carving on the open face. These fins aren't for the faint hearted they are made for power surfers who like to push hard against their fins and draw out their turns. *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.
