2023 Cabrinha :03 Fusion Alloy Foil Mast MKII

The 2023 Cabrinha :03 Fusion Alloy Foil Mast MKII is an aluminum hydrofoil mast built for the Cabrinha Fusion modular foil platform. Cabrinha designed this second-generation (MKII) mast using extruded, anodized 6061-T6 aircraft-grade aluminum, producing a rigid and hydrodynamic profile across all four available lengths. The mast uses a precision tapered fuse-to-mast connection and features helicoil inserts at all screw points to resist saltwater corrosion — a common weak spot on alloy hardware. It fits any standard 9 cm foil box and connects to the Fusion fuselage via a three-screw interface, with a choice of fixed top plate or Cabrinha's FQR (Foil Quick Release) configuration.

• Material: Extruded, anodized 6061-T6 aircraft-grade aluminum
• Chord: 146.6 mm (all sizes)
• Thickness: 16.2 mm (all sizes)
• Available lengths: 40 cm, 65 cm, 75 cm, 85 cm
• Top plate options: Fixed or FQR (Foil Quick Release)
• Connection: 3-screw system
• Foil box compatibility: 9 cm industry standard
• Corrosion protection: Helicoil inserts at connection points

This mast suits a wide range of riders within the Cabrinha Fusion ecosystem, from beginners building their first complete setup to intermediate foilers looking for a durable, lower-cost alternative to carbon. The 40 cm length is aimed at riders learning to foil or those who want a short mast for shallow-water sessions, while the 65–85 cm lengths cover the typical range for open-water wing foiling and kite foiling. Because aluminum is heavier and slightly less stiff than carbon at the same length, this mast leans toward durability and value rather than outright race performance.

Riders who prioritize low maintenance and resistance to dings will appreciate the 6061-T6 construction and helicoil hardware. The FQR top-plate option also appeals to anyone who frequently swaps boards, since it allows tool-free mast changes on the water or beach.

Within Cabrinha's Fusion MKII foil range, the Alloy Mast sits as the entry-level and mid-range mast option. The step up is the Fusion Carbon Hollow Mast, available in 74 cm, 84 cm, and 94 cm lengths, which offers lighter weight and increased stiffness at a significantly higher price. The alloy mast pairs with any Fusion MKII fuselage and is compatible with both the X-Series (mid-aspect) and H-Series (high-aspect) front wings and stabilizers, making it a practical starting point for riders who plan to upgrade components over time.

Compared to alloy masts from brands like Slingshot or North, the Fusion Alloy MKII is competitively positioned on price and shares the same general material grade. Its distinguishing details are the helicoil corrosion protection, the tapered fuse connection, and the FQR quick-release option — features that tie it tightly into Cabrinha's modular parts ecosystem.
