Cabrinha Union Carbon Foil Mast – High-Modulus Carbon, Low Drag & Performance-Tuned Lengths

Overview

The Cabrinha UNION Carbon Mast is a high-performance foil mast engineered to deliver exceptional stiffness, reduced drag, and precise control across a range of foiling disciplines.

Constructed from high-modulus carbon, the UNION mast is designed to minimize deflection while maintaining a lightweight, streamlined profile. Its redesigned UNION connection reduces the fuselage cross-sectional area by 15%, creating a more efficient transition between the mast and fuselage.

Available in 78 cm and 84 cm lengths, each option is tailored to a different riding style—from prone and downwind foiling to freestyle, freeride, and wave riding.

Key Features

• High-Modulus Carbon Construction – Delivers a high level of stiffness designed for precise rider input and efficient foil control.

• Low-Drag Profile – Streamlined mast and connection geometry are designed to reduce unnecessary drag.

• Reduced-Section UNION Connection – The redesigned connection decreases fuselage cross-sectional area by 15%, according to the manufacturer.

• Reduced Deflection – Engineered to provide improved stiffness compared with previous mast generations under deflection testing.

• Precision Handling – Increased rigidity helps create a direct connection between rider input and foil response.

• Two Performance-Tuned Lengths – Choose the mast length according to discipline and riding style.

• 78 cm Mast – Designed for prone and downwind-focused riding.

• 84 cm Mast – Designed for all-around freestyle, freeride, and wave foiling.

• Streamlined Fuselage Integration – The redesigned connection promotes a cleaner overall hydrodynamic profile.

• Complete Mounting Hardware – Supplied with board mounting hardware and required mast/fuselage connection screws.

78 cm vs. 84 cm

Why the UNION Mast Stands Out

The UNION is designed around the relationship between stiffness and efficiency. A rigid carbon mast helps transmit rider input directly through the foil system, while the streamlined connection is designed to reduce drag at one of the most important junctions in the setup.

The two available lengths also allow riders to select a mast based on the type of foiling they prioritize rather than relying on a single universal configuration.
