Artemis efoiler®

The world's first commercially viable, zero emission propulsion solution for high speed maritime transport

Patented technology

Introducing our transformative Artemis eFoiler® electric propulsion system – a revolutionary design developed to help decarbonise our seas, shape the future of maritime, and position Artemis Technologies as the clear market leader in high-speed vessels and propulsion systems.

The Artemis eFoiler® is subject to a number of granted patents and pending patent applications in multiple countries.

Artemis eFoiler® benefits

A game changer for the decarbonisation of high-speed maritime transport applications, the technology provides a range of benefits for both operators and passengers.

Operational

The autonomous flight control system ensures a smooth ride, mitigating the effects of seasickness often associated with wavy conditions. Due to the fully submerged electric drivetrain, the Artemis eFoiler® provides a quiet experience.

The design of the Artemis eFoiler® provides significant range at high-speed, whilst also reducing operational costs through substantial fuel savings and reduced maintenance.

Environmental

Electric propulsion generates zero emissions in operation, removing air, water and noise pollution.

By flying above the waves, Artemis eFoiler® propelled vessels produce minimal wake, allowing for high-speed, close-to-shore operations within busy waterways whilst protecting wildlife, shorelines and anchored vessels.

Commercial

The Artemis eFoiler® works at an unmatched efficiency of more than twice as efficient as traditional diesel engines.

The design of the Artemis eFoiler® provides significant range at high-speed, whilst also reducing operational costs through substantial fuel savings.

Vessels developed with eFoiler® propulsion will operate with up to 90% lower fuel costs compared with traditional ferries, with the capability of carrying up to 150 passengers.

Energy system

includes an Artemis Technologies 800V marinised EV battery, with a hydrogen fuel cell range extender option under development.

Hydrofoils

Retractable high aspect ratio hydrofoils with replaceable leading edges, that lift vessel out of the water.

Steering system

Aft hydrofoil acts as a rudder to steer under propulsion, with thrusters to assist in low speed manoeuvres.

Propulsion

Zero emission propulsion provided by a self-cooled, ultra-high power density, 97% efficient electric drivetrain. Minimal servicing requirements.

Flight control system

Ride height of the vessel is managed by an autonomous flight control system.

Autonomous flight control

The autopilot flight control system is a critical feature of the Artemis eFoiler® system. It is responsible for maintaining safe operation and actively stabilises our vessels in both foiling and displacement modes.

Developed on our full motion platform simulator, the flight control system has been used extensively to develop the performance of autopilot in a variety of conditions.

In foiling mode, it autonomously controls the ride height, roll and pitch of the craft, enabling the pilot to focus on heading and speed during operation.

Comfortable ride

Foiling above the water removes the usual bumpy ride and associated sea sickness. Performance of the Artemis eFoiler® technology and the 100% electric vessel has been validated during sea trials against its gasoline displacement sistership allowing us to record up to 6x fewer vibrations on the body to ensure optimal protection for crew and passengers.

Reduced wake

The minimal wake of the Artemis eFoiler® system ensures vessels can avoid local speed restrictions,. This allows for high-speed operations close to shore, making Artemis eFoiler® vessels an ideal solution for traditionally busy waterways in ports and cities.

The reduced wake produced by our vessels helps protect our shorelines, wildlife and anchored vessels.
