The Slater Designs Boss Up I-Bolic Surfboard is the bigger brother of the S Boss, Kelly's first-ever mid-length. Designed by Dan Mann in partnership with Kelly Slater and Kevin Schulz, this utility mid-length is the most well-rounded and versatile shape in the Slater Designs range, crafted to cruise across weak wave faces and grind through cavernous overhead tubes.
The Boss Up is the board you would travel with if you could only bring one board with you. Your one board quiver with maximum performance in a purely versatile package. Recommended to ride roughly +13 liters more volume than your standard shortboard, paired with the KS1 5 Fin Template configured as a Quad.

Product Construction
I-Bolic Technology
Speed, control, strength and response. A core engineered with an I-Beam down center for added strength with flex controlled at the rails using high density foam from nose to tail. Most similar to a PU core.
Additional Info
Wave Type
This is the most versatile board in the Slater Designs range, it works in everything from smaller surf to barrels. The crew has been loving it in punchy surf with an open face, a perfect board for carving and linking turns. While many look at this shape for small and gutless surf, it would work well at a big point break like Pavones or Rincon, or even a big day at Sunset.
Board Features
The Boss Up is an elongated evolution of the S Boss, with bigger dimensions and a longer rail line for enhanced drive and versatility across all conditions. This shape is one that doesn't command you dial-in your volume perfectly - any single surfer can ride the Boss Up in a variety of sizes. Around +13 liters of volume more than your standard shortboard is the team's recommendation.
I-Bolic Core Technology
The Firewire patent pending I-Bolic core technology is an engineering feat developed for performance, without the need for external carbon layups or heavy laminations. These models offer the stiffness of Linear Flex Technology (LFT) with the flex and spring-back of their best-selling Helium technology. This is Kelly Slater's favorite technology to ride, offering speed, control, strength and response.
I-Bolic Performance
I-Bolic cores have the stiffness of the Firewire old Linear Flex Technology (LFT) with the flex and spring-back of their best-selling Helium technology. The I-beam ensures firmness underfoot and unparalleled break strength, while the high density foam parabolic rails enable flex and recoil through turns.
I-Bolic Construction
The Firewire I-Bolic technology is a 1.5 lb EPS foam core with a 18mm high density foam stringer in the core, 16mm high density foam parabolic rails to control flex, and a 5mm high density foam springer on the bottom. Paired with their standard fiberglass lamination, on the deck it has a 3mm high density composite deck skin on the deck sandwiched between the double 4 oz E fiberglass cloth layers, and also has double 4 oz E fiberglass capping the bottom.
I-Bolic Lamination Compatibility
I-Bolic cores are paired with standard fiberglass lamination, AWT fiberglass lamination, and Volcanic lamination.
