Fossil-Fuel Engine Comparison

On fossil-fuel powered boats, running in the 65–80% power range is usually recommended to optimise fuel efficiency and engine life. This economical cruising speed strikes an ideal balance between fuel consumption and speed.

🔋

The New Stream Advantage

Thanks to the high thrust they deliver at low kW levels, New Stream electric propulsion systems reduce the throttle that fossil-fuel engines use in their 65–80% economical cruising range down to just 40–65%. This both saves energy and yields a more efficient cruise. As a result, longer voyages are possible without needing large-volume (high-kWh) battery packs.
