Abstract
Systems and methods for indicating a navigable area that is reachable by a watercraft with a current amount of energy is provided. The system comprises a display, a processor and a memory, including a computer code configured to, when executed by the processor, cause the system to receive position data indicating a current geographic location of a watercraft; receive tidal data for the current geographic location of the watercraft; determine, based on energy remaining data, an estimated available travel distance for operating a motor of the watercraft before the watercraft runs out of energy; and generate an overlay for a chart. The overlay comprises a boundary area corresponding to the estimated available travel distance and the effect of the tide on the watercraft. The computer code further presents the overlay on the chart to visually indicate travel options from the current geographic location.
