The Firewire Spaceship Ibolic Surfboard 5'11 28.7L is Kelly Slater's personal favorite shape for quality surf — a refined, performance-oriented outline engineered by Mike Woo (@woosurfboards) that thrives in tubes, on rail, and in any wave with a clean, round face.

Wave Type: This is Kelly's go-to when the waves are good — reef passes, point breaks, hollow beachies, and performance sessions at breaks like Lowers. Recommended in 2–6' surf, from average to epic conditions. Not a small-wave board — the Spaceship rewards commitment and clean, powerful waves.

Board Features: Decades of R&D from Mike Woo are built into this outline — a rounded pintail for rail hold and arc control, a single concave under the front foot that runs into a double concave between the feet for drive and speed, and performance rails designed to hold in round wave faces. The shape has the DNA of a Bali tube-shooter, refined for the full spectrum of good waves.

I-Bolic 2.0 Core: I-beam core construction with high-density foam rail flex and a fully engineered carbon strip inlay on the bottom deck — increased strength, speed, and response over the original I-Bolic, with an updated look.

Sizing: 5'11" x 28.7L is a performance volume — suited to surfers approximately 145–165 lbs (66–75kg) who surf with commitment in quality conditions. Best paired with Kelly's KSR or KS1 fin templates.

Care: Rinse with fresh water after each session. Store out of direct sunlight and heat.
