TWIN FIN
FAST LINES , FREE SLIDES *COMPLETELY NEW BOARD FOR 2025/26*
Experience a board engineered for speed and freedom.
The TwinFin’s unique shape, with a pronounced hip behind the fins, delivers dynamic, agile turns and a loose, skate-like ride that lets you carve high-line rail maneuvers effortlessly. Its innovative channel tail boosts acceleration and aids tail recovery during radical slides, keeping you in control on every wave. Whether you’re tackling small, less-powerful surf or challenging overhead conditions, the TwinFin empowers intermediate surfers to push harder turns while offering advanced riders a high-performance, fluid ride.
> ULTIMATE SPEED & FLOW
Enjoy fast down-the-line speed with reduced drag and a refined channel. The Twin Fin keeps you flowing even through weaker sections, linking maneuvers with ease and maintaining momentum.
> EFFORTLESS TURNS & LOOSER FEEL
A looser, skatey ride makes sharp pivots and tail slides second nature. The hip and moon tail create a natural pivot point, ensuring quick direction changes and smooth transitions.
> VERSATILITY ACROSS WAVE SIZES
Surprisingly adaptable in overhead waves, the Twin Fin provides enough hold to pump off the bottom and boost off the lip. Ideal for intermediate surfers seeking easy speed or pros craving stylish performance.
> CHANNEL TAIL RELEASE - Generates lift and extra speed while broadening the sweet spot for both front- and back-foot surfers, aiding recovery and maneuver setups.
> FINE RAILS TO THE TAIL - Boosts responsiveness and agility. Fuller nose rails help drive down the line, while thinner nose rails cut swing weight for faster rotations.
> DOMED OR FLATTER DECKS - Smaller sizes feature a domed deck for sensitivity and thinner rails, while wider models have a flatter deck for added stability and comfort.
> TWINZ FIN SETUP - Two large fins minimize drag for faster rides, giving both solid hold and easy tail release. Add a nubster fin for extra control and bite in bigger surf.
HOW IT COMPARES -
The Twin is best for smaller, weaker waves, letting intermediate surfers perform more radically with less technique. It stays lively throughout the wave, generating easy speed and quick recoveries. Despite its small-wave focus, it can handle well overhead surf, pumping off the bottom and racing sections. Compared to the Spice and Pro, the Twin is looser and unlocks speed faster. The Pro remains the high-performance choice in bigger, critical conditions, delivering top hold and control. The Spice offers versatility with quad or thruster setups, plus bevel rails for smooth rail-to-rail transitions and added hold. The Twin complements but doesn’t replace either, appealing to those seeking relaxed lines, high-speed arcs, and tail slide turns.
Spice • Most stable & versatile (jack-of-all-trades) • Mid-point control for responsive turns • Adaptable fin setups (quad/thruster) |
TwinFin • Fastest & most fluid down-the-line • Effortless tail release with a twin-fin design • Versatile across small and overhead conditions |
Pro • High-performance precision in hollow, powerful surf • Narrower nose for tighter maneuvers • Vertical approach for sharper snaps |

THE CONSTRUCTION CHOICES;
ACUTE CUSTOM CARBON - low weight, high strength and dynamic flex to create a board that is livelier, more responsive, and has a higher breakage threshold. Over two years and more than 20 prototypes, the construction was refined to produce a perfect balance of lightness, flex and durability through the blend of fibreglass and carbon in a variety of angles and degree orientations.
LIMITED SERIES - We wanted the construction to be offered at a very competitive price point, while maintaining solid performance in the surf, without sacrificing the weight or strength. Twin T-stringers made from glass fibre are positioned on the deck and bottom of the board close to the rail, providing a massive increase in the overall strength against total breakage in surf.
› An additional wide layer of 200g glass wraps the rails for higher strength against paddle impact and further reinforces the overall strength against buckling.
› The deck features reinforced biaxial glass and Australian pine, to resist heel dents and impact from the standing area.
› The nose and tail are wrapped in multiple layers of glass fiber for further strength on these impact zones.

Works well

I ordered easily and the voucher arrived promptly. Also an email from the business was really nice.

Great equipment, decent price and very prompt delivery.

I have used this board on flat water in calm and very windy conditions. I really like this board it handles really well, is a pleasure to paddle and seems quite quick. one of the reasons for choosing this board was it is designed for lighter weight paddlers, it really does fit the bill in that respect. All in all a brilliant board. In addition the service I received from Poole Harbour Watersports was excellent.

Amazing product

Great company very helpful

Really prompt service, great choice of products, excellent.

Absolutely fantastic
