A New Class of Watercraft

See The Difference

Legacy eFoils rely on passive balance, forcing the rider to absorb pitch instability and rough chop in real-world riding conditions. XFOIL introduces active control technology, a fundamental shift in watercraft engineering that predicts water variance for an effortlessly smooth, superior ride.

Safety Architecture

Designed for Confidence on the Water.

Apex is built with layered protection systems for waterproofing, rider safety, motor protection, and recovery support.

Double-Layer Waterproofing

Layered waterproof protection helps defend critical internal systems from water exposure during marine use.

Clear Inspection Window

A clear inspection window gives riders a fast visual check point for added confidence before and after riding.

Board Angle Detection Shutdown

The system can detect abnormal board angle conditions and shut down to help reduce unsafe operation.

Instant Shutdown

Designed to cut power immediately when shutdown conditions are triggered.

Anti-Runaway System

Helps prevent the board from continuing uncontrolled if the rider separates from the board.

Auto Power-Off on Fall

Automatically cuts power when a fall or separation event is detected.

Self-Rescue Mode

Provides added support for controlled recovery situations if a remote malfunction occurs.

Anti-Propeller Cavitation Recovery

Helps the propulsion system recover more smoothly if cavitation interrupts thrust delivery.

Propeller Guard Included

The propeller guard is included as standard for added rider confidence during setup, learning, and riding.

Overheat Protection

Built-in protection helps manage thermal conditions and protect the propulsion electronics.

Overcurrent Protection

Electronic safeguards help protect the system from excessive current conditions.

WHAT RIDERS SAY

Paul McDonnell

Oahu, Hawaii • Verified Rider

Smooth, intuitive, and powerful. I recorded the fastest lap of the day against more expensive boards. The xFoil dominated the entire field.

Joshua Adam

Sydney, Australia • Kickstarter Community

After meticulously vetting every competitive platform on the market, the technical specifications of the XFoil matched or exceeded the highest-tier options available—all while offering an unmatched value proposition that saved me thousands.

James Dvorak

Maui, Hawaii • EFoil Community Leader

Your equipment worked flawlessly — awesome foils! The build quality at this price point is genuinely hard to believe. Feels like a board costing three times as much.
