Designed in collaboration with the legendary Kelly Slater, this board promises an thrilling ride that’ll leave you grinning from ear to ear.
GREAT WHITE
The Firewire Great White Twin is a performance twin fin designed by Kelly Slater and Bali-based shaper Mike Woo, built around the outline of a great white shark. It paddles like a hybrid, rails like a shortboard, and generates speed where most boards stop working.
WHO
The Great White Twin is for surfers who want a twin fin that performs at their level — not a fun board they have to surf down to.
- The shortboard surfer who wants more paddle and wave count without giving up critical surfing
- The intermediate surfer ready to move past basic fish and into something that responds to committed surfing
- The experienced surfer looking for a small-wave weapon that can still be pushed in overhead conditions
- The Kelly Slater or Slater Designs follower looking for the most complete performance twin in the lineup
- The surfer who needs one board that works when the surf is weak but doesn't fall apart when it gets good
This board earns its spot in your quiver by making average days genuinely fun and good days exceptional.
WHEN
The Great White Twin is designed for the full range of everyday surf — from weak, mushy conditions where most shortboards struggle to generate momentum, up through solid overhead surf where it holds and drives with confidence. Its hidden center volume catches waves early without sacrificing rail feel, and the elevated tail rocker gives it control in hollow, more powerful conditions. Whether you're surfing punchy reef on the south shore or inconsistent beach break, this board finds speed where it looks like there isn't any and stays composed when the power increases.
WHAT
The Great White Twin's outline was traced directly from photos of a great white shark — both the top and bottom views — which gave it a wide nose, a defined hip near the twin fin placement, and a narrower, more pulled-in tail than most fish. That hip acts as a pivot point and keeps the rear end responsive without letting the tail wash out. Volume is concentrated through the center of the board, which makes it paddle and catch like a much larger board, while the fine rails maintain contact through the turn and give it the immediate pocket response of a shortboard. The elevated tail rocker pushes it further into high-performance territory, particularly on the backhand.
Built in Ibolic + Volcanic construction, the Great White Twin delivers a particularly firm and drivey feel underfoot. The I-beam EPS core provides uncompromising break strength and three points of flex control along the length of the board, while the basalt fiber Volcanic lamination adds responsiveness and deck durability that outperforms standard fiberglass. The result is a board with real hold and precision — it doesn't flex around under your feet in powerful surf, and it responds immediately when you commit to a turn. This is a construction that suits surfing with intention.
