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.
