The Mashup is a collaboration between Rob Machado and Dan Mann. Firewire describes it as a melding of each of their most popular designs — combining DNA from the Seaside (Machado's twin-fin small-wave board) and the Spitfire (Dan Mann's everyday hybrid). The result is a board that goes fast in weak waves but also drives vertically when the surf has push.

Firewire's product page includes customer reviews. One reviewer (185 cm & 96 kg) reports surfing the 5'6" Mashup in a rapid wave pool and describes it as an absolute standout. The shape is designed to immediately make you feel like you've got speed and buoyancy to burn.

Helium Core Technology uses a stringerless EPS core with flex controlled at the rails via Paulownia and Balsa wood — the same construction used across Firewire's performance range.

Pros & cons

DNA from the Seaside and Spitfire — fast in weak waves, drives vertically in good waves
5-fin Futures box lets you run twin, thruster, or quad depending on conditions
Helium construction (stringerless EPS with Paulownia/Balsa rail flex) is light and lively
Hybrid nose keeps plenty of paddle volume despite the short length

Not designed for solid overhead surf
Fin choice dramatically changes the ride — expect to experiment
At $890 MSRP, priced above equivalent PU-blank hybrids

How it surfs

Because Surfex does not personally test boards, the notes here summarise what Firewire and retailers describe about the shape rather than a first-person ride report. Firewire positions the Mashup as a hybrid that bridges the gap between small-wave twin-fin speed and vertical performance.

MSRP on the Firewire US site is $890. The board is stocked at independent retailers including Cleanline Surf and Revo Surf — see the retailer comparison below for live listings.
