Futures Mayhem 3.0 Tri Fins - Medium
“The Mayhem 3.0 is an all new template. With the trends in modern HP shortboards going towards more curve under the rear foot for critical pocket surfing, we felt the need for the fins to evolve with the board rockers. We wanted to add a bit more base, with more rake and a narrower tapered tip than our long-standing thruster template.
The idea with the base and rake is more resistance and bite when deep into turns and to maintain drive through tight radius turns. The reduced tip area, with a tapered flex, adds release and freedom for quick transitions in and out of turns, when needed. We’ve been taking these fins to the wave pools for controlled, repeatable testing, and also worked with our crew of diverse sized, elite surfers for feedback and input.”

Construction Honeycomb w/ CarbonHoneycomb, reinforced with carbon
A honeycomb core with carbon through the base. You get the balanced, all-round flex of Honeycomb with extra stiffness low down where the drive comes from, so it holds a harder turn without going stiff all over.
Ride Number 5.4 · Balanced
Honeycomb w/ Carbon spans 4–8; this fin sits at 5.4.
Carbon base
Drive where it countsCarbon through the base keeps the bottom of the fin stiff and engaged, so your weight goes into the turn instead of washing out through flex.
Honeycomb body
Balanced flexThe hexagonal core above the base keeps the weight down and the flex lively. That is what stops a stiff base feeling dead underfoot.
Where it sits
Between Honeycomb and TechflexMore drive and hold than standard Honeycomb, without the full speed-control stiffness of fiberglass. Futures builds the Mayhem, Pyzel and Rasta templates this way.
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 5.4 · 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.
