An instrument designed to estimate fuel consumption efficiency for watercraft, it typically takes into account variables such as fuel used, distance traveled, and engine operating time. As an example, an operator could input the number of gallons consumed during a trip, along with the nautical miles covered, to determine the fuel efficiency in miles per gallon.
The ability to accurately assess fuel efficiency offers several advantages. Economically, it allows operators to budget for fuel costs and identify opportunities to reduce spending. Environmentally, understanding fuel consumption promotes responsible boating practices and aids in minimizing the environmental impact of engine emissions. Historically, rudimentary methods of tracking fuel use were employed; however, modern electronic or digital tools provide far more precise measurements and calculations.
