2026 Cabrinha Union Carbon Mast

The 2026 Cabrinha Union Carbon Mast is a 16mm high-modulus carbon foil mast built around Cabrinha's new Union connection system. Developed through a collaboration between Cabrinha and Mikeslab, the Union platform represents a new generation of Cabrinha foils, replacing the brand's earlier foil architecture with a connection interface designed to increase stiffness and reduce drag at the mast-to-fuselage junction. The mast uses a monobloc (one-piece) construction with unidirectional pre-preg carbon, pairing a thin aerodynamic profile with high torsional rigidity. It ships with a padded mast cover, all necessary mounting hardware, and a T40 Torx torque tool.

The Union Carbon Mast is offered in two lengths — 78 cm and 84 cm — to suit different riding conditions and preferences. The shorter 78 cm option targets shallow-water spots and tighter, more technical foiling, while the 84 cm length adds clearance and stability for open-water riding and higher-speed sessions.

• Profile thickness: 16 mm
• Carbon type: High-modulus unidirectional pre-preg
• Construction: Monobloc (one-piece)
• Available lengths: 78 cm, 84 cm
• Connection system: Union (Mikeslab-licensed)
• Compatible wing series: Prestige, Fusion
• Included hardware: 4× M8×30 mm bolts, 4× T-nuts, 2× M8×45 mm bolts, 1× M8×25 mm bolt, T40 Torx tool, padded mast cover

This mast is aimed at intermediate-to-advanced foilers who want a stiff, low-drag carbon mast without stepping up to the even thinner (and pricier) Apex 14 mm option. The 16 mm profile delivers firm feedback under load and minimal flex through hard carves, making it well suited to wing foiling, prone surf foiling, and powered downwind runs where direct energy transfer matters. Riders progressing past aluminum or entry-level carbon masts will notice a meaningful jump in glide efficiency and top-end speed.

Because the Union connection is specific to Cabrinha's current foil ecosystem, this mast pairs with the Prestige and Fusion front-wing families plus compatible stabilizers. Riders already invested in Union-platform components can swap mast lengths without changing any other hardware.

Within Cabrinha's 2026 foil range, the Union Carbon Mast sits as the standard high-performance option — one tier below the Union Apex Carbon Mast, which uses a thinner 14 mm ultra-high-modulus layup for additional stiffness and drag reduction at a higher price point. Riders chasing the absolute stiffest setup will gravitate toward the Apex, while the 16 mm Carbon Mast offers a strong performance-to-value balance for most foiling disciplines.

The broader Union system launched as a ground-up redesign of Cabrinha's foil lineup, moving away from the brand's previous connection geometry to the Mikeslab-derived Union interface. Comparable carbon masts from other brands include options in the Axis and Armstrong ranges at similar price points, though cross-brand compatibility does not apply — mast and fuselage connections are proprietary to each system.
