Abstract
The navigation device mounted on a ship is provided with processing circuitry. The processing circuitry receives a start position and a destination position associated with the ship, calculates a reversal route from the destination position towards the start position, evaluates a possibility of generation of the reversal route from the destination position to the start position, and determines that the destination position is within a non-navigable area when there is no possibility of the generation of the reversal route.
