Slide background


Each Triple7 fin is cast from aircraft grade aluminum, chosen for its low weight yet superior strength. The form is hand-finished and polished, then coated with chromium to protect against corrosion. This process ensures that each fin has a perfectly solid foil that never changes.


Finautic was inspired by the detailed engineering and precise construction seen in aviation. As a premium manufacturer of SUP fins, Finautic designed the Triple7 line to be the fastest and highest quality solution for racing, cruising, and downwind paddle boarding.


A cleanly shaped foil, like an aircraft wing or racing boat rudder, translates to turbulence-free directional tracking for racing and touring, while also maintaining maneuverability. The rake sheds weeds and allows for a high surface area without deep draft.
