Foils are modular, and the right spares and accessories keep yours running, let you tune its ride, and extend its life. This collection brings together kitesurfing foil spares and accessories, including front wings, stabilisers, fuselages, masts, mastbases, screw and hardware sets, and protective bags. Whether you need a replacement part, a tuning option, or the hardware to keep everything tight, it is here.

We stock spares across leading foil systems, including North, Cabrinha, and CORE, so you can find parts that match your setup. Foil hardware takes a hard life in salt water, so having the right spares to hand means a small issue never cuts a session short.

Not sure which part you need? The guide below explains the main foil components and how they affect the ride. Browse the range below, and see our kitesurfing foils range for complete setups.

How a Foil Comes Apart

A hydrofoil is built from several parts that bolt together: the mast that connects to the board, the fuselage that joins the wings, the front wing that provides most of the lift, and the rear stabiliser that controls pitch and balance. Because these parts are separate, you can replace a damaged piece, upgrade one component, or swap wings to change the ride, all without buying a whole new foil.

Front Wings: Lift and Speed

The front wing has the biggest effect on how a foil rides. A larger front wing generates more lift at lower speed, which helps you get up and foiling in lighter wind and makes learning easier. A smaller front wing is faster and more manoeuvrable but needs more speed to stay up, suiting experienced riders in stronger wind. Many riders keep more than one front wing to cover different conditions.

Stabilisers and Fuselages

The rear stabiliser fine-tunes the ride, affecting pitch stability and how the foil turns. A larger stabiliser feels planted and forgiving, while a smaller one is looser and more playful. The fuselage length changes how quickly the foil pitches: a longer fuselage is more stable, a shorter one more agile. Swapping these parts is a simple way to tune a foil to your preference as your riding develops.

Masts and Mastbases

The mast sets how high you ride above the water and how the foil connects to the board. Taller masts give more clearance for carving and choppy water, while shorter masts are easier when learning. The mastbase or baseplate is the connection point to the board, and keeping it and its bolts in good order is essential for safety. A damaged mast or worn base should be replaced promptly.

Screws, Bolts, and Hardware

Foil hardware is small but critical. Titanium and stainless bolts, track nuts, and spring nuts hold the whole assembly together under big loads, and salt water is hard on them. Having the correct screw packs and spares, such as North's titanium spring nuts or foil screw sets, means you can keep everything torqued correctly and replace any bolt that corrodes or rounds off. Never ride a foil with worn or missing hardware.

Matching Spares to Your System

Foil parts are generally designed to work within a brand's system, so compatibility matters. North, Cabrinha, and CORE each use their own connections and fittings, and parts are not always interchangeable between brands. When choosing a spare, match it to your foil's system and model. If you are unsure, our team can help you identify the right part so it fits and performs as intended.

Bags and Protection

Foil wings and masts have fine edges and surfaces that are easily chipped, which affects performance as well as looks. A padded foil bag or quiver bag protects the parts in transit and storage, and covers keep individual wings safe. Protecting the foil properly is one of the easiest ways to keep it performing and to preserve its value.

When to Replace a Part

Replace a foil part when it is damaged, worn, or no longer safe. Cracks or deep chips in a wing, a bent mast, corroded or rounded bolts, and a worn baseplate are all reasons to fit a new part. Catching these early protects the rest of the foil and keeps you safe on the water. Tuning upgrades, like a different front wing, are a matter of choice rather than necessity.

Caring for Foil Parts

• Rinse the whole foil in fresh water after every salt-water session
• Dry and lightly grease bolts to slow corrosion
• Check and torque hardware regularly to the correct settings
• Protect wings and masts in padded covers or a bag
• Store somewhere dry, out of direct sunlight and heat

Good care keeps hardware working and foil surfaces in top condition.

How Much Do Foil Spares Cost?

Prices vary widely with the part. Screws, nuts, and small hardware are inexpensive and worth keeping in stock, while front wings, masts, and fuselages are larger investments that reflect their construction and materials. Spares and tuning parts are usually far cheaper than a whole new foil, which is the beauty of a modular system: you repair or upgrade only what you need.

Frequently Asked Questions About Kitesurfing Foil Spares and Accessories

Are foil parts interchangeable between brands?

Generally no. North, Cabrinha, and CORE use their own connections and fittings, so match spares to your foil's system and model rather than mixing brands.

What does the front wing change?

It has the biggest effect on the ride. Larger front wings lift earlier for light wind and learning, smaller wings are faster and more manoeuvrable for stronger wind.

Why do I need special bolts?

Foil hardware carries big loads and sits in salt water. Titanium and stainless bolts resist corrosion, and keeping spares means you can replace any that corrode or round off.

How do I tune my foil's feel?

Swapping the front wing, stabiliser, or fuselage changes lift, stability, and turning. It is a simple way to adjust the ride as your technique develops.

When should I replace a foil part?

Replace any cracked or deeply chipped wing, bent mast, corroded bolt, or worn baseplate. Catching damage early protects the rest of the foil and keeps you safe.

How do I protect my foil in transit?

Use a padded foil bag or individual wing covers, rinse and dry the parts first, and store everything dry and out of direct sunlight.
