Emission-free and low-maintenance, built with industrial components that last for years.

The range · custom

The series as
a starting point.

The full GM series in one overview, all on a safe 48 V. Above 75 kW we leave the standard series behind and design the system to spec, up to 1 MW.

Custom

From retrofit to
complete engineering.

Every custom project is different. These are the paths we help with most often.

Special hulls

Work boats, ferries and tugboats with their own requirements and integration with onboard equipment such as hydraulics.

Retrofit

New life for the old sailing fleet and classic ships, emission-free and with regeneration while sailing.

Fleets

Multiple boats with one standardized drivetrain, easy to maintain and expand.

Complete engineering

From a new boat concept to delivery. We think along from the first sketch to the ready-to-sail boat.
