The present disclosure provides a ship monitoring system capable of easily grasping whether a ship passes through the front or the rear of another ship. The ship monitoring system includes a first estimator, a second estimator, and a passage determinator. The first estimator estimates an estimated position of a first ship after a first period of time in each direction, based on first ship data indicative of a position and a velocity of the first ship, by using a first formula, when assuming that the first ship travels after the first ship changed the course at the current position into an arbitrary direction. The second estimator estimates an estimated course of a second ship and an estimated position of the second ship after a second period of time, that is included in the estimated course of the second ship, based on second ship data indicative of a position and a velocity of the second ship, by using a second formula. The passage determinator determines that, among the estimated course of the second ship, a side closer to the current position of the second ship than a matched point at which the estimated position of the first ship matches with the estimated position of the second ship, when the first period of time is equal to the second period of time, is a range where the first ship passes through either one of the front and the rear of the second ship, and a side far away from the current position of the second ship than the matched point is a range where the first ship passes through the other of the front and the rear of the second ship.
