  • Overview

    • Upright keel template designed for traditional fish shapes.
    • Lower sweep (rake) than most conventional, wider-based keels which allows it to pivot in a tight radius.
    • High area and depth not only deliver a feeling of control when pushed harder on the open face but help to maintain tremendous speed through roundhouse cutbacks.
    • Black and clear in Performance Glass.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Recommended for all board types including fish, funboard and twin fin boards.

  • Performance Glass

    Performance Glass (PG) fins are machine-cut from layers of solid fibreglass. These fins are stiff and are widely used by-level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.

    Happy medium

    I’ve used them in my 7’6 MR midlength. Happy medium of drive and pivot for a keel! I really like them!

    Mondern Keel Fin

    Great fin - pivots well. Turned a Lost Hydra 41L boards meant to be a quad into a twinny Keel and this allows it to snap lips with pretty amazing release for a groveler. Little tough on backside snaps and/or backside in general, but alas, the plight of a twinny. Overall - great fin with great drive and excellent pivot for such a large drivey keel fin. I recommend if you are looking to loosen up a groveler.

    Great performance keep fins.

    Love these fins. Plenty of drive and hold but tall enough to allow you to do tighter arcs too.

    The air core are a great material that seem to take a bit of weight out of the board and add a bit of buoyancy which helps in really small surf.

    Excellent product. Lots of drive, with enough control to do some performance surfing. Great mid way point between a traditional keel and modern upright twin.
