S BOSS
The Firewire S Boss is a high-performance shortboard born from a collaboration between Kelly Slater and shaper Dan Mann — designed to surf faster, turn tighter, and work across more conditions than any conventional shortboard. With volume hidden into a compact, parallel-rail outline, it delivers genuine performance without demanding the conditions to match.
WHO
The S Boss is for surfers who want real performance without having to wait for perfect waves to get it.
- The advancing intermediate ready to step into a shortboard that actually rewards commitment and keeps up with them as they improve
- The experienced shortboarder who wants one board that covers everything from beach breaks to punchy reef — without sacrificing drive or response
- The performance surfer looking for a shape that generates speed on its own terms instead of relying on steep rocker and narrow rails to do the work
- The surfer who's been riding the same high-performance shortboard for years and wants something that feels familiar but opens up new possibilities on every wave
This is a board that grows with you, and adapts to the lineup instead of demanding the lineup adapt to it.
WHEN
The S Boss was built for the waves that show up most — chest-high and above, across a range of conditions. When punchy beach breaks are firing, it locks into turns quickly and releases cleanly off the top. At a more defined reef or point break, the parallel rails hold a line and carry speed through longer sections without getting stiff or mechanical. It's at its best when the surf has some energy behind it, but the hidden volume and relaxed rocker mean it doesn't shut down when conditions are average. Hawaii's range of reefs, beach breaks, and variable swell direction makes it a natural fit in the islands.
WHAT
The S Boss starts with a bullet nose — a chopped blunt front end that eliminates swing weight and allows the parallel-rail outline to run all the way to the tail. Kelly Slater's concept was to feel the board turn from the rails rather than the rocker, and that's exactly what this design delivers. A low-to-moderate rocker carries speed down the line without sacrificing control, while a unique V contour under the chest transitions into a double barrel concave through the back half and exits out the round tail with speed and directional hold. S-deck foot wells on the deck plant your feet exactly where they need to be. The result is a tight turning radius, fast rail transitions, and surprising control for a board built to fit in small pockets.
In Ibolic construction, the S Boss is firm underfoot and responsive without feeling stiff — the I-beam core and parabolic rail system flex through turns and rebound quickly. The Ibolic+Volcanic option adds basalt fiber lamination over the same core: Firewire's most durable build, with a responsive, lively feel that holds up to hard use. Both constructions feel noticeably livelier than traditional polyurethane without sacrificing the connected, familiar feel that performance surfers want underfoot.
DIMENSIONS

CONSTRUCTION OPTIONS
Ibolic: I-beam high-density EPS core with parabolic rail system — stiff and responsive underfoot, with a controlled flex pattern that recoils quickly through turns.
Ibolic + Volcanic: Same Ibolic I-beam core with basalt fiber lamination — Firewire's most durable construction and their sustainable alternative to carbon, with elevated responsiveness.
FIN CONFIGURATIONS
5-Fin. Rides as thruster or quad. Fins not included.

FREQUENTLY ASKED QUESTIONS
How do I size the Firewire S Boss?
The S Boss is designed to be ridden shorter than your regular shortboard and sized on the higher end of your volume range — the hidden volume in the outline does more work than it looks. Dan Mann recommends going a few inches shorter than your current board and erring toward more foam rather than less. The right size depends on your weight, your usual board volume, the break you surf most, and how often you're in the water. Contact us and we'll help you find the right fit:
- Email: sales@hawaiiansouthshore.com
- Text: (808) 597-9055
When you reach out, include your current board dimensions and volume, what construction you're considering, the type of break you surf most (beach break, reef break, or point break), how often you surf, and your location — location helps us give you accurate shipping information.
What's the difference between the S Boss and the FRK Plus?
Both are Kelly Slater and Dan Mann performance shortboards, but they surf differently. The FRK Plus has a narrower, more pulled-in outline and is built for surfers who want maximum performance in critical, powerful waves — it demands more from the conditions and the surfer. The S Boss has a fuller outline, more volume distribution, and a more forgiving fin cluster, making it the more versatile of the two. If you want a board that performs at a high level across a wider range of everyday surf — not just when conditions are firing — the S Boss is the right call.
Can intermediate surfers ride the S Boss?
Yes. While the S Boss was developed with high-performance surfing in mind, the relaxed rocker, full outline, and accessible volume make it a board advancing intermediate surfers can genuinely grow into. It rewards commitment and improves with the surfer. The key is getting the sizing right — riding it with enough volume to paddle well and stay comfortable while building confidence in the shape.
