  • Overview

    UNIQUE TEMPLATE

    Radically different side & centre fin templates create a powerful fin set with ultimate speed & drive.

    • SIDE FIN PROFILE: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.
    • CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers feeling of predictability when releasing through turns.
    • FIN FOILS TEMPLATE: Thicker base with tapered tip optimises flex & regulates the release of energy during rail to rial transitions.

    Thruster

    Bought three sets for my quiver. Love the design and the quality is tops. First ride as a thruster really lit up my old board. A change to these fins made everything faster and better while easier to control. Next I rode a quad which I felt was perfect before but the new H4. (2 large, 2 small) set up was even better than before. I am trying them out in different boards and fin size combos. I think they are a superior design and materials and craftsmanship are second to none. The center fin is uniquely spot on. The hatchet side fins have to be felt to be believed, excellent feel and hold, fast yet smooth control, with a purposeful outline. A real beauty too! My feeling is that these fins work exceptionally well in smaller size surf and they should be even better with more wave size as needed. I think they nailed it on the H4, flexible snappy yet speedy firm response. I am looking forward to summer for sure now!

    North Shore Game Changer

    Put it on my 9'0 custom Kekoa Uemura HP longboard. It does what its designed for

    Pure Speed. Put it to the test in 6 to 8 Hawaiian Scale North Shore Juice and it past with flying colors. Put it on rail and the board cam alive.

    Very happy with this fin technology.

    SO STOKED🤙🏾🤙🏾

    Worked great on my small wave groveler

    Initially used it on my Slater Designs Sci fi 2.0. Felt a bit too twitchy on that board. Made the board feel a bit hard to settle down. However used it on my small wave CIS Pod mod and it worked great in that board. Lots of speed and made the board feel very lively.
