MASHUP
The Firewire Mashup is a collaboration between Rob Machado and Dan Mann ā a board built by merging the best elements of two of their most celebrated designs, the Seaside and the Spitfire. The result is a hybrid shortboard that generates effortless speed in weak surf while holding up to real turns in better waves.
WHO
The Mashup is for surfers who want one board that works when the waves don't ā and still delivers when they do.
- The intermediate surfer who's outgrown their fish but doesn't always have the power to push a standard shortboard
- The experienced surfer looking for a dedicated small-wave board that can still handle a good day
- The shortboarder who wants to stay loose and keep surfing without switching boards between sessions
- The surfer who rides the Seaside and wants more performance range out of a similar shape
- The everyday surfer who needs something versatile enough to grab without checking the forecast
This board rewards surfers who prioritize feel and flow over raw performance in critical conditions.
WHEN
The Mashup is built for the everyday ā inconsistent, weaker surf where most shortboards go flat. Its generous volume distribution and hybrid outline generate speed early and carry it through soft sections that would stall a higher-performance shape. When conditions pick up to head-high and punchy, the step rails, swallow tail, and double concave bottom give it enough drive and control to hold its line and turn with intention. It's not a step-up, but it handles far more than its groveler label suggests. Hawaii's average day ā the kind of surf that comes around more than the good stuff ā is exactly where the Mashup earns its place.
WHAT
The Mashup borrows its nose from the Spitfire and its tail from the Seaside, then builds a hybrid rail line that lets those two halves work together. The wide point sits slightly forward of center, giving the board excellent paddle power up front. Step rails in the back third of the board pack in extra volume where you need it without making the outline feel bloated. The double concave runs throughout the bottom and becomes more pronounced from the center to the tail ā generating speed early and translating it into responsiveness off the back foot. The swallow tail keeps the back end loose and maneuverable, letting the board pivot and redirect without needing big wave power to do it.
In Helium, the Mashup is light and lively ā the parabolic wood rail system creates a loaded, spring-back flex that helps the board come alive in soft, slower surf. In Volcanic, that same core gets basalt fiber lamination, adding stiffness and impact resistance for surfers who prioritize durability without sacrificing too much of that Helium responsiveness.
DIMENSIONS

CONSTRUCTION OPTIONS
Helium: Firewire's lightest EPS core construction ā stringerless foam with parabolic Paulownia and Balsa wood rails running the full length of the board, combined with a proprietary composite deck skin. Built for maximum speed generation and lively flex response in everyday surf.
Volcanic: Helium core with basalt fiber lamination in place of standard fiberglass. Basalt is a natural, volcanic rock-derived material with carbon-like strength
FIN CONFIGURATIONS
5-Fin. Rides as thruster, quad, or twin. Fins not included.

FREQUENTLY ASKED QUESTIONS
What size Firewire Mashup should I order?
Sizing the Mashup depends on your weight, your current board setup, how you surf, and what conditions you're riding it in. The Mashup tends to be ridden slightly longer than a Seaside and slightly shorter than a Dominator 2 ā if you're coming off a performance shortboard, adding a few liters of volume over your normal board is a solid starting point. Contact us directly and we'll help you dial it in:
- Email: sales@hawaiiansouthshore.com
- Text: (808) 597-9055
When you reach out, include your current board dimensions and volume, which construction you're considering, the type of breaks you surf most (beach break, reef break, point break), how often you surf, and your location ā location affects shipping options and helps us give you accurate delivery information.
Can the Mashup be ridden as a thruster, quad, or twin?
Yes ā the Mashup has a 5-fin box setup, so you can configure it any way you like depending on conditions and preference. Most riders default to quad for smaller, weaker surf where you want maximum down-the-line speed, and switch to thruster when the surf picks up and you want more hold and pivot off the tail. Twin is also a popular setup for a looser, skatier feel. Fins are not included with the board ā you'll need to pick up a set separately.
What's the difference between the Firewire Mashup and the Seaside?
The Seaside is a pure quad-only groveler ā wide, flat, and built around generating speed in the weakest surf. The Mashup takes that small-wave ease and adds more performance range. It runs a hybrid outline that's narrower through the tail than the Seaside, blending in the Spitfire's nose and a 5-fin box setup that lets you ride it as a thruster, quad, or twin depending on conditions. The Mashup paddles similarly to the Seaside but turns more aggressively and holds up better when the surf has real push. If you want maximum glide in the tiniest conditions, the Seaside. If you want something that works on the small days but doesn't get left behind when the surf improves, the Mashup.
