The present disclosure provides a ship monitoring system capable of visualizing a risk of a collision or an approach in a width direction perpendicular to a heading of another ship. The ship monitoring system includes a first data generator, a second data generator, and processing circuitry. The first data generator 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 risk value indicative of a risk of a collision between the first ship and the second ship is above a threshold 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. The processing circuitry further display a polygonal OZT (Obstacle Zone by Target) having vertexes at least comprised of a rear end and a front end of the risk range, and a representative point of the first ship located at a position corresponding to the rear end of the risk range.
