Construction BlackstixFaster. Lighter. More responsive.
A V2 inside foil that generates and holds speed through turns, wrapped in a precision carbon and fiberglass matrix with lightweight epoxy resin. The liveliest fin Futures makes — it will make your board feel like a different board.
Ride Number 8.3 · Speed generating
Blackstix spans 7–10; this fin sits at 8.3.
V2 foil
Speed generatingConcave at the base, flattening out toward the tip. Water flows across the fin more cleanly, giving lift through every stage of the turn and an effortless rail-to-rail feel — even when the wave has no push in it.
Carbon and fiberglass matrix
Highly responsivePrecision-shaped carbon and fiberglass over a lightweight core, engineered for a highly responsive flex pattern. That is the snap and liveliness only Blackstix has.
Epoxy resin
Light. Lively.A proprietary epoxy that is lighter, tougher and more responsive than polyester. It also emits 50-75% fewer VOCs, so there is less nasty chemistry involved in making it.
Template Rake Drawn-out, swept back
A long, drawn-out outline that holds all the way through a turn. Rake templates carve rather than snap — drive off the bottom, hold in the pocket, and the most stability of the three shapes. If you surf on rail and like long lines, this is your shape.

Ride Number 8.3 · Speed generating How Futures rates every fin
Feel = Flex + Rake + Foil
Futures rates every construction on a 1–10 scale. Low numbers hold a predictable line and control your speed. High numbers generate speed and snap out of turns. Three physical properties combine to produce it, and they are not weighted equally — flex counts for the most, then rake, then foil.
Solid, engaged, predictable. Built for powerful conditions.
All-around. Drive, hold and looseness in equal measure.
Springy, fluid, responsive. Built to create speed from nothing.
Flex is how much the fin bends under load — soft generates speed, stable controls it. Rake is the sweep of the outline — upright turns tight, laid-back holds long. Foil is the cross-section — a V or V2 foil feels fluid, a flat foil feels engaged.
Sizing Which size am I? Sized to rider weight, not board length
Futures sizes fins to the surfer, not the board. Find your weight, then fine-tune with construction and template once you know your size.

The bands overlap on purpose. If you sit on a boundary, size up for more hold and drive, or down for a looser, easier-to-turn feel.
