Pair with the all-new Endorfins KSR Tri-Quad Fin Set and KSR Tri Fin Set for the best experience, Kelly prefers riding size Large in bigger waves and size Medium in smaller waves.

Product Construction
Proflex Technology
Their latest innovation in technology bringing together what Firewire's known for with sandwich construction and flex controlled through an engineered build. Featuring a Technorra carbon cage, 6oz carbon, basalt carbon tape, and their proprietary deck skin for unparalleled durability.
Additional Info
The board ridden by the 11x World Champion during his memorable Kirra sessions in March 2024, meet the Slater Designs Spaceship Surfboard by Mike Woo and Kelly Slater. A high performance model for good waves, the Spaceship represents decades of R&D by Mike Woo (@woosurfboards). Having previously shaped the Great White Twin for Kelly inspired by the outline of a Great White Shark, Mike and Kelly set out to craft a more conventional outline designed for hold in tubes, turns on rail, and hold in round wave faces from Canggu to Coolangatta.
Unveiled in March 2024 during Kelly's historic sessions at Kirra, this is Kelly's favorite shape for good waves, especially reef passes, point breaks, and perfect beach breaks.
Wave Type
This is Kelly Slater's favorite shape for good waves - a more conventional outline with incredible hold in round wave faces. The shape comes to life in tubes over reef passes, turns on rail at point breaks, with lots of hold in perfect beach breaks, but also works as a performance shortboard at waves like Lowers.
Board Features
This shape has the DNA of a Bali-tube-shooter, the Spaceship represents decades of R&D by Mike Woo. Featuring a rounded pintail with a single concave in the front half of the board that runs into a double concave between your feet, performance rails, and rocker to fit into the curve of good waves.


Proflex Build Technology

Introducing Proflex Technology is their latest, most high-performance construction made with carbon, developed in partnership with the 11x World Champion, Kelly Slater. This build was engineered directly to Kelly's preference in carbon performance, not too stiff and closer to "broken-in right-out-of-the-box" when you get it. The Spaceship by Kelly Slater and Mike Woo is just the beginning, stay tuned for more shapes built in Proflex Technology.
Proflex Performance
Meet Firewire's latest, most high-performance construction made with carbon, Proflex Technology. Offering superior strength and performance, reduced weight, and controlled flex, this sandwich construction is built for critical, high-performance surfing.
Proflex Core Compatibility
Proflex Technology is neither a core construction nor a lamination construction specifically, it's a combination of the both: a truly unique build.
