The Slater Designs Boss Up surfboard is Kelly Slater’s first high-performance midlength, designed in collaboration with Dan Mann and Kevin Schulz. Regarded as the most versatile board in the Slater Designs range, it combines maneuverability, speed, and control to perform from small waves to powerful barrels.
This model is the bigger brother of the S Boss, with a longer shape and larger dimensions that deliver more drive and versatility in all conditions. It’s the perfect one-board quiver, ideal for travel and tackling any wave with maximum performance.
It is recommended to ride it with +13 liters of volume compared to your regular shortboard, set up with the KS1 5-fin template in quad to unlock its full potential.
✔ Wave type: extremely versatile, working in everything from small, soft waves to powerful point breaks like Pavones or Rincon, and even on big days at Sunset.
✔ Key features: longer rail line, added float, easy to connect turns, and adaptable to different sizes without needing precise volume tuning.
The Firewire Boss Up is your ultimate all-around board, designed for surfers seeking versatility and top-level performance in a single design.
Epoxy Ibolic Volcanic Construction:
The I-Beam Core construction system provides optimized flex control at the rails using high-density foam, a true engineering innovation designed for maximum performance.
It also incorporates basalt lamination technology, a sustainable alternative to carbon, more environmentally friendly, delivering superior durability and enhanced response in every wave.
A unique breakthrough that combines strength, sustainability, and high performance in next-generation surfboard design.
