Cabrinha Union Apex Carbon-14 Mast - 2026

Mike’s Lab has long been synonymous with cutting-edge hydrofoil design, consistently pushing the boundaries of performance and innovation in water sports.

Founded by Mike Zajicek, who crafted his first custom windsurfing board in 1978 and turned his passion into a full-time profession by 1986, the company has evolved into a beacon of excellence in hydrofoil manufacturing.

The hallmark of Mike’s Lab foils lies in their meticulous craftsmanship and functional design.

Each foil is engineered with an unwavering attention to detail, ensuring optimal performance for riders.

One of the most critical parts of a hydrofoil is the connection between mast and fuselage — streamlined enough to reduce drag, yet strong enough to remain rigid with modern wingspan designs.

Licensed from the original Mikeslab system, the Union is the blend of two companies — and the critical junction between rider and the ocean.

DESIGN PROFILE

Superior stiffness with minimal drag.

The UNION APEX mast is an ultra high modulus carbon mast offering superior stiffness with minimal drag. The ultra-thin 14mm profile impressively lowers drag while maintaining maximum stiffness, and excels thanks to exceptional torsional stiffness.

The UNION connection reduces the fuselage cross-sectional area by 15%, creating a more streamlined and efficient outline.

The mast is available in 2 sizes, each tailored for a specific riding style:
– 78cm for prone and downwind purists
– 84cm for all-around freestyle, freeride, and waves

FEATURES

• 14mm ultra high-modulus carbon layup for exceptional stiffness and direct feedback
• Monobloc construction reduces drag and improves energy transfer for better glide and higher top speed
• Unidirectional pre-preg carbon maximizes stiffness while keeping weight down
• Thin, aerodynamic profile cuts drag for easier early lift, longer glide and higher top end
• UNION connection for maximum stiffness and low drag

*Includes cover, 4pcs M8×30mm screws with 4pcs T-nut board mounting hardware, 2pcs M8×45mm, 1pc M8×25mm, T40 Torx torque tool.

TECH SPECS

3 SCREW CONNECTION – Super simple 3 screw connection design lowers assembly time and improves hydro efficiency.

15% REDUCTION – New fuselage outline reduces projected area by 15% vs the previous Fusion system for improved efficiency and performance.

PREPREG HIGH MODULUS CARBON – Premium construction balances stiffness and strength for a more direct ride feel.

CHOOSE YOUR FRONT WING

We offer 3 sizes in the Prestige to choose from:

1. 760 – high performance
2. 905 – all-round versatility
3. 1150 – maximum glide

CHOOSE YOUR STABILIZER

Smaller stabilizers feel more manoeuvrable (less stable). Larger stabilizers feel more stable and locked-in.

1. 160 – loose and playful
2. 180 – versatile all-round performance
3. 200 – maximum stability

CHOOSE YOUR MAST

Cabrinha offers two high modulus carbon masts (78cm and 84cm) to suit different riding styles:

• Carbon Mast – 16mm high modulus carbon
• Apex Carbon Mast – 14mm ultra high modulus carbon

• 78cm – Surf foil / Downwind foil / Wing foil
• 84cm – Wing foil / Tow foil / Kite foil

FAQ – Cabrinha Union Apex Carbon 14 Mast (2026)

Quick answers to help you choose the right mast length and setup.

What is a foil mast?

A foil mast is the vertical structural component that connects the foil to the board, helping maintain stable flight and stiffness through the system.

Why choose a carbon mast?

Carbon masts are lightweight and stiff, reducing flex for more direct control, improved pumping efficiency, and better overall foil response.

Which size should I choose: 78cm or 84cm?

78cm is a great choice for surf and downwind focused riding and shallower water. 84cm offers more clearance and is the more versatile option for wing, tow and kite foiling.

Is this mast compatible with other Union foil parts?

Yes — it’s designed for the Cabrinha Union system and fits Union front wings, stabilizers and fuselages using the Union connection standard.

What is included with this mast?

Includes the mast, cover, mounting hardware and a T40 Torx torque tool. Front wings, stabilizers and boards are sold separately.
