| 摘要 |
A propulsion system for a marine vessel comprising an engine driving a generator for supplying electrical power to a propulsion motor, an operator display, a fuel consumption sensor, a vessel position sensor, a vessel speed sensor, and a controller configured to receive inputs from the fuel consumption, vessel position and vessel speed sensors and calculate the vessel's efficiency through water and efficiency over land, wherein both efficiency values are displayed on the operator display as volume of fuel consumed per distance traveled (over land or through the water).
