The vessel
The EC34 is the platform’s largest standard model — a 34-metre foil-assisted catamaran sized for the longest-range commercial passenger ferry routes, large-capacity offshore crew transfer operations, and high-capacity excursion and tourism services. This is the size class that serves Norwegian fylkeskommune coastal routes, Gulf inter-emirate and inter-island passenger services, and large offshore crew transfer to fixed installations.
At this scale, the foil-assist energy advantage compounds: longer routes mean larger fuel or battery budgets, and a 50% reduction in drag or an over-80% reduction in energy consumption translates to operating-cost differences that dominate the route economics over a typical 14-year vessel service life.

Operator outcomes
Open-water route economics that close. Longer commercial passenger and crew-transfer routes face a structural problem with conventional-hull electrification: the battery weight required for usable range often makes the vessel infeasible or pushes it into a higher class with higher operating cost. The foil-assisted electric EC34 reduces energy consumption by over 80% compared to a conventional diesel comparator — opening routes that aren’t viable on a conventional electric platform.
Up to 50% lower drag in diesel-to-diesel newbuild replacement. For operators running longer routes with refuelling infrastructure but no shore-power, the diesel-configured EC34 still delivers up to 50% lower drag at design speed, with proportional fuel and emissions savings expected. Substantial OPEX reduction without requiring electrification investment.
Fleet-scale platform for renewal programmes. Counties, ferry operators, and offshore agencies running multi-vessel renewal programmes can standardise on a single platform across routes of different lengths by combining the EC34 with smaller EnviroCat models. The shared platform reduces fleet-wide training, maintenance, and spare-parts complexity.

Propulsion (configurable — multiple options supported)
| Mechanical propulsion | Controllable-pitch propellers (Kumera Helseth, Servogear), Volvo Penta IPS Electric pods, or waterjet propulsion |
| Electric drive (electric and hybrid configurations) | Brunvoll Mar-El, ZEM, or other compatible suppliers |
| Total continuous power | [TBC] kW |
| Total peak power | [TBC] kW |
At EC34 scale, propulsion choice has significant route-economics implications. Long-route electric configurations typically favour pod systems or CPPs for efficiency at sustained cruise; high-passenger-density tourism routes may favour waterjet for shallow-water access. See Approach for the analytical-engagement model.

Use cases
Large passenger ferries. Norwegian fylkeskommune coastal routes, Gulf inter-emirate and inter-island passenger services, longer-distance commercial passenger transport. Configuration: high-density passenger seating, comfort-focused cabin layout, accessibility provisions, optional cargo deck.
Offshore crew transfer. Crew movement to fixed installations, longer-route offshore service. Configuration: optimised for crew capacity, baggage and equipment handling, transit comfort, sustained-cruise reliability. The 14–28% retrofit drag advantage (in retrofit cases) and 50–80% newbuild energy advantage translate directly to operating-cost reduction across high-utilisation crew-transfer routes.
Excursion and tourism. Multi-hour scenic and excursion operations with high passenger volume and premium experience expectations. Configuration: panoramic viewing, comfort-focused passenger areas, low-noise foil-assisted electric drivetrain for unobtrusive operation in scenic and protected waters.
