A ship monitoring system has a first data generator that generates first ship data indicative of a position and a velocity of a first ship. The second data generator generates second ship data indicative of a position and a velocity of a second ship. The processing circuitry specifies a risk range where a ship area occupied by the first ship or a watch area set around the first ship overlaps with a ship area occupied by the second ship or a watch area set around the second ship, among an estimated course of the second ship, based on a position of the first ship and a position of the second ship at each timing, that are estimated from the first ship data and the second ship data, when assuming that the first ship changes a course to an arbitrary direction and crosses the estimated course of the second ship.
