Everything about this fin, explainedOverview About this fin What it is, who it suits, and it on film
Jack Robinson's new signature thruster fin in the Rake template category is scaled down to grom size. Developed to suit Jack's style of surfing above and below the lip, he has been putting it through the paces at some of the best waves in the world with incredible success. The centre fin is smaller than the side fins for increased maneuverability.
The Honeycomb construction features a balanced flex pattern that provides a perfect blend of lively and stable performance in all wave types.

Construction HoneycombAll-around performance
A lightweight hexagonal core drops the weight without giving up flex. Stiffer than Blackstix, more flexible than fiberglass, and sat right in the middle of the scale. The standard upgrade fin, and the one that covers the widest range of conditions.
Ride Number 5.5 · Balanced
Honeycomb spans 4–7; this fin sits at 5.5.
Honeycomb core
The core mattersThe hexagonal core mat cuts the resin content, so the fin gets lighter while staying stiff where it counts. That is what gives Honeycomb its medium flex — mushy beach break or pumping reef point, it works.
Balanced performance
Balanced constructionMedium flex puts Honeycomb square in the balanced band. Drive down the line, hold through turns, or boost airs — it does all three without specialising in any one of them.
Legacy is built on this
Shape, not materialEvery Legacy Series fin is Honeycomb, so you feel what changing the shape alone does. Rake, Neutral and Pivot — same material, three genuinely different feels.
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 5.5 · Balanced 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.
