The FCS II Carver Glass Flex Thruster Large fin set from the Essential Series. This fin has an elongated template for executing long arcing turns. The Carver has an extended sweep angle that provides excellent control off the bottom and when carving the face. Particularly good in point-break and reef-break waves. This is the ‘go-to’ fin set for power surfers who push hard against their fins and carve long drawn-out turns on the wave face. FCS recommend the Carver for boards with deep concaves and moderate-to-extreme rocker.
