Engineering Built on Real-World Experience
Before developing an electric platform, we spent years around different forms of water sports—from WingFoil and EFoil to electric surfboards and other board sports. Different locations, different riders, and different conditions revealed the same challenge.
The experience should not be limited by wind, waves, or rider skill.
Wind & Foiling
WingFoil, Efoil and kiteboarding in real-world conditions.
Leisure & Exploration
Electric foiling in recreational and exploration environments.
Electric Foiling
Long-term testing of electric propulsion in everyday water conditions.
Electric Water Sports
Exploring how electric propulsion changes water-sports applications.
Engineering for Electric Foiling
The difficult part of electric foiling is not simply making power. It is making the system survive, perform, and remain serviceable on the water.
Waterproofing & Corrosion
Designed for continuous exposure to salt water.
- Sealing
- Connectors
- Enclosure
- Corrosion resistance
- Pressure & leak testing
Battery Lifecycle
Designed around battery lifecycle, not just battery capacity.
- BMS integration
- SOH monitoring
- Cycle monitoring
- Cell protection
- Thermal management
Propulsion Stability
Stable propulsion across different riding conditions.
- Motor tuning
- ESC algorithm
- Power management
- Control dynamics
- Thermal behaviour
Modular Serviceability
Replace what fails—not the entire system.
- Shared battery and ESC architecture
- Reduces inventory complexity and service costs.
- Replace individual modules—not the entire system.
WHO WE ARE?
An engineering company focused on electric hydrofoil propulsion systems.
We develop modular propulsion, battery, and control systems for electric hydrofoil applications, with a focus on reliability, serviceability, and integration.
WHAT WE DO?
- Modular electric propulsion systems
- Integrated battery systems & lifecycle management
- Waterproof electrical architecture
- Mechanical & electrical integration
- Prototype development & system validation
WHY ALTUSFOIL?
We make electrification easier for water-sports manufacturers.
Instead of building an electric propulsion team from scratch, manufacturers can integrate a proven propulsion platform into their own board and foil designs.
