Slater Designs Spaceship I-Bolic 2.0 Surfboard

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.

I-Bolic 2.0 Core Technology

I-Bolic 2.0 is Firewire’s second-generation composite technology — designed to deliver maximum strength-to-weight performance, tuned controlled flex, and long-term durability. Unlike traditional PU boards that rely on a central wood stringer, I-Bolic 2.0 features a patented composite I-Beam stringer system combined with high-density parabolic rails, distributing flex energy throughout the entire structure. The result is a lively, responsive, and incredibly durable surfboard that maintains consistent performance session after session.

The I-Bolic blanks undergo 3 shaping stages:

1. CNC-cut EPS core
2. Deck cut I-Beam and deck installation
3. Rail and bottom cut
4. Final finish shaping

I-Bolic 2.0 Technology Core
At the heart of I-Bolic 2.0 is a 1.5 lb fused-cell EPS core, precision-milled and engineered through a combination of high-density foam and lightweight EPS that internally balances buoyancy with rebound response. Running through the center is the I-Beam stringer, constructed from GR-80 aerospace-grade high-density foam. This core beam is capped with 2.0 lb high-density EPS flanges on both the roof and floor — creating a true I-Beam geometry that controls both torsional flex and longitudinal stiffness.

Flanking the structure, 2.0 lb high-density EPS parabolic rail inserts provide progressive flex control and reinforcement through the turn radius, allowing the board to store and release energy efficiently. The deck skin is made from MPP (Modified Polypropylene) and is bonded to the top deck using a 2.5 oz e-glass, enhancing bond strength and durability while providing a smooth, consistent flex response across the surface. A 2 inch Engineered Carbon Fiber Inset Tape runs along the bottom deck rocker for longitudinal strength and durability.

All components are bonded through a vacuum-laminated sandwich process using Entropy Bio Resin, the same plant-based epoxy system used across all Firewire and Slater Designs boards, ensuring consistent flex integrity, lower VOC emissions, and superior environmental performance.

I-Bolic Technology Materials

• Core Foam: 1.5 lb Fused-cell EPS (lightweight + high-density blend)
• I-Beam Stringer: GR-80 aerospace high-density foam
• I-Beam Caps (Roof & Floor): 2.0 lb high-density EPS flange
• Parabolic Rail Inserts: 2.0 lb high-density EPS
• Deck Skin: MPP (Modified Polypropylene) bonded with 1.8 oz epoxy fiber cloth
• Top Deck Lamination: 1 x 4 oz fiberglass layer
• Bottom Deck Lamination: 2 x 4 oz fiberglass layers + 2" engineered carbon fiber inset tape
• Resin System: Entropy Bio Resin (plant-based epoxy)
• Outer Shell Finish: 2K UV Stability Spray Finish (keeps the board white longer and prevents yellowing)

Freshwater Performance & Buoyancy
EPS foam performs better in freshwater wave pools due to its higher relative gravity profile, which provides superior buoyancy. EPS/epoxy boards deliver approximately 2–3% more net flotation than PU boards of the same volume in freshwater, where reduced water density affects board lift.

Example estimates (freshwater, same volume):

• 30 L board: EPS +2.2% lift advantage (~0.6 kg)
• 35 L board: EPS +2.2% lift advantage (~0.7 kg)

I-Bolic 2.0 Technology Key Tech

• GR-80 Aerospace I-Beam Stringer: Central beam distributes flex and resists torsion.
• 2.0 lb HD EPS I-Beam Flanges: Enhance stiffness along top and bottom planes.
• 2.0 lb HD Parabolic Rails: Maintain rebound energy and flex control through turns.
• MPP Deck Skin + 1.8 oz Epoxy Fiber Layer: Maximizes bond strength and surface durability.
• 1 x 4 oz Top Deck Lamination / 2 x 4 oz Bottom Deck Lamination: Balanced flex and reinforced structure.
• 2" Engineered Carbon Fiber Inset Tape: Runs along the bottom deck rocker for longitudinal strength and durability.
• Entropy Bio Resin System: Used in all Firewire boards for high strength, durability, and sustainability.
• 2K UV Stability Spray Finish: Keeps the board white for longer and protects from UV degradation.

I-Bolic 2.0 Summary
I-Bolic 2.0 delivers a crisp, responsive feel — fast and energetic underfoot with exceptional control and strength. It combines the lightness of EPS with the precision and power of a structural composite, giving surfers that “connected yet alive” feeling unique to Firewire technologies.
