Artemis Technologies is trying to turn “fast ferry” into “clean, quiet and flying ferry,” using its eFoiler electric hydrofoil platform to lift vessels out of the water, cut drag, remove emissions in operation and trim operating costs for high speed routes and offshore work. From its Belfast base, the company is rolling out passenger ferries and workboats that can carry up to 150 people at 30 plus knots while targeting fuel cost reductions in the 80 to 90 percent range versus conventional diesel craft.

Operators and owners benefit by:
Using Artemis eFoiler vessels to replace diesel high speed craft with electric foiling ferries and workboats that cut OPEX, emissions and wake.
- Removing emissions on high speed routes: Artemis positions its ferries and workboats as zero emissions in operation, aimed at decarbonising fast commuter and offshore segments that are usually hard to abate.
- Cutting fuel cost exposure: The combination of electric propulsion and hydrofoils delivers very high propulsive efficiency, with Artemis materials pointing to fuel cost reductions on the order of 80 to 90 percent compared with conventional fast ferries once capex is in the water.
- Improving passenger comfort and experience: Foiling above the waves removes much of the bumpy ride and slamming associated with displacement hulls, which can reduce seasickness and support higher average speeds without sacrificing comfort.
- Unlocking constrained waterways: Minimal wake from the foiling hull allows operations closer to shore and within sensitive waterways at speed, which can shorten journey times on urban routes where wake restrictions currently slow conventional craft.
- Lowering routine maintenance load: A fully electric drivetrain with fewer moving parts and no combustion machinery reduces scheduled maintenance compared with fast diesel ferries, and ultra fast charging concepts are designed so vessels can return to service quickly between rotations.
- Aligning with future regulation and funding: Artemis sits at the intersection of clean tech and public transport, benefiting from innovation grants and zero emission corridor initiatives, which can help operators frame projects for green finance and public tenders.
- Serving multiple mission profiles: The same eFoiler platform underpins passenger ferries, crew transfer vessels and workboats, so operators can look at a family of vessels that share technology rather than one off projects on each route.
- Anchoring projects in a proven ecosystem: Artemis leads the Belfast Maritime Consortium and has already moved EF 24 passenger builds and EF 12 workboats into sea trials and early orders, which gives buyers more confidence that this is not a paper concept.
- Getting closer to the source: Operators can explore technical details, vessel variants and deployment concepts directly with the Artemis team. Visit artemistechnologies.co.uk .
Notes: This summary is based on Artemis materials and external coverage. Real savings depend on route length, port layout, charging strategy, electricity pricing and how fast you need to run to protect schedules.

Fast ferry switch sketch – diesel to eFoiler
A simple way to estimate annual cost and CO₂ shifts if a conventional high speed ferry route moves to an Artemis style electric foiling vessel.
Route and fuel profile
Typical fast ferry fuel burn at the speed you actually run.
Artemis talks about large energy savings thanks to foiling and electric drive – adjust to your own view.
Tank to wake factor for fuel oil often sits a little above three tonnes of CO₂ per tonne of fuel.

Artemis operates in a very specific corner of the market – fast routes where conventional diesel ferries burn hard to keep journey times down. The grid above gives operators a quick way to test whether those routes are big enough, busy enough and fuel hungry enough for an eFoiler style switch to matter, before they dig into the detailed engineering, port layout and funding work that a real project will demand.
