The vessel
The EC22 is the mid-size member of the EnviroCat platform — a 22-metre foil-assisted catamaran sized for regional passenger ferry routes, ambulance and search and rescue services, and tourism operations. The platform serves duty cycles that the EC16.5 is too small for, but where the EC34’s scale isn’t required: typical fjord and coastal passenger routes, regional emergency response, and tourism operators carrying 50–150 passengers per departure.
The same foil-assist hull architecture and propulsion-options matrix that anchors the platform across all sizes is configured here for passenger comfort, medical-equipment integration, or tourism-deck layouts depending on operator requirement.

Operator outcomes
Up to 50% lower drag, over 80% lower energy. EC22 newbuilds replacing a conventional diesel catamaran of comparable size deliver up to 50% lower drag at design speed (diesel-to-diesel case) and, in foil-assisted electric configuration, over 80% lower energy consumption compared to a conventional diesel catamaran. For passenger ferry and tourism operators facing rising fuel costs, CO₂ pricing, or zero-emission tender requirements, the platform changes the operating-cost calculus.
A platform that fits regional Norwegian and Gulf routes. The 22-metre size class sits in the middle of the route-length distribution for both Norwegian coastal passenger ferry routes and Gulf passenger and crew transfer services. Battery sizing, propulsion configuration, and use-case fitout are tuned per route through the analytical engagement before commitment.
Comfort and stability in mixed sea states. The foil-assist hull reduces wave-impact at cruise compared to a conventional planing catamaran of equivalent size — a passenger-experience benefit that matters for tourism, ambulance, and high-frequency commuter routes alike.

Use cases
Passenger ferries. Regional Norwegian fjord and coastal routes, Gulf passenger services, similar mid-route operations. Configuration: optimised passenger seating, comfort-focused cabin, low-noise electric operation where applicable.
Ambulance. Coastal and inshore medical transport — patient comfort during transit, stability for medical procedures, equipment integration. Configuration: medical-equipment fitout, stretcher access, dedicated medical-crew workspace.
Search and rescue. Coastal SAR with higher passenger / survivor capacity than the EC18 workboat-class. Configuration: rapid-response deck layout, MOB equipment, recovered-person cabin.
Tourism. Excursion and sightseeing operations with passenger comfort, viewing decks, and sustainability story for operator branding. Configuration: outdoor seating, panoramic viewing, low-noise foil-assisted electric drivetrain.
