SES-X hull is the next generation Surface Effect Ship (SES) solution, introducing an air cushion between the water and the vessel. Our technology significantly reduces energy consumption in high speed compared to conventional hulls. Additional benefits are increased comfort, great seakeeping capabilities and reduced wave production.

Scalable platform architecture

The SES-X technology platform consists of the air cushion system, driveline, and batteries. All components are integrated and regulated by our ride control system. The platform architecture is robust and scalable for boats from 6 meters to 30 meters. It is optimized for electric boating, and the advanced ride control system ensures best-in-class energy efficiency.

Superior energy efficiency


For conventional vessels the energy consumption increase significantly with speed

Therefore zero emission has been challenging for high-speed vessels. SES-X’ introduces game-changing energy efficient technology. The air cushion reduces water friction by reducing the wet surface area of the hull. This enables electric high-speed boats without compromise.

Compatible with standard propulsion systems

The energy efficient technology allows smaller, lighter and cheaper propulsion systems. SES-X’ solution integrates elegantly with commercial off-the-shelf propulsion systems. Our system is compatible with full-electric, hybrid, diesel and future proof for hydrogen.

Examples of different propulsion systems

SES-X’ advanced ride control system ensures that vessels have best-in-class energy efficiency and seakeeping abilities.

Ride control system

Numerous onboard sensors collect operational data from the vessels. We use machine learning to continuously improve control algorithms in the ride control system. Through over-the-air software upgrades, we can improve the vessel’s performance over time. The onboard dashboard provides instant information about the vessel, and through the online dashboard you can access real time and historical data.

International patented technology

Our unique hull solution is a combination of a catamaran and monohull, gaining the stability and deck space of a catamaran and the hull volume of a monohull. The air cushion provides the seakeeping and efficiency of a hovercraft. The technology is patented internationally and we have several patents pending.
