Abstract
A process is provided by which the operator of a marine vessel can invoke the operation of a computer program that investigates various alternatives that can improve the range of the marine vessel. The distance between the current location of the marine vessel and a desired waypoint is determined and compared to a range of the marine vessel which is determined as a function of available fuel, vessel speed, fuel usage rate, and engine speed. The computer program investigates the results that would be achieved, theoretically, from a change in engine speed. Both increases and decreases in engine speed are reviewed and additional theoretical ranges are calculated as a function of those new engine speeds. The operator of the marine vessel is informed when an advantageous change in engine speed is determined.
