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 and CO2 emissions in high speed compared to conventional hulls. Additional benefits are increased comfort, great seakeeping capabilities and reduced wave production.

Scalable platform architecture

SES-X’ technology platform consists of the air cushion system, driveline, and ride control system. The platform is robust and scalable for boats from 6 meters to 30 meters. The platform architecture is optimized for electric boating, and the advanced ride control system ensures best-in-class energy efficiency

Superior energy efficiency


For conventional vessels, the water resistance and fuel consumption increase substantially with speed.

Therefore, zero emissions vessels typically have only been available for slow-speed vessels. SES-X opens up for emission free and high speed vessels with game-changing energy efficiency. The air cushion reduces water friction by reducing the wet surface area of the hull, which enables high speed and zero emission

Compatible with standard propulsion systems

The energy efficient technology allows smaller, lighter and cheaper propulsion systems. The SES-X solution integrates elegantly with conventional off-the-shelf propulsion systems, such as Volvo Penta IPS or waterjet. Our system is compatible with full-electric, hybrid, diesel and future proof for hydrogen. Contact us for more details on driveline energy system.

Examples of different propulsion systems

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

Ride control system

Numerous onboard sensors collect operational data from the vessels, and SES-X utilize machine learning to continuously improve control algorithms in the ride control system. Over-the-air software upgrades 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 operational data

International patented technology

The 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. Our hull technology is patented internationally and we have several patents pending.
