Abstract
An apparatus for judging presence or absence of an abnormality of a marine vessel includes a controller configured or programmed to function as an estimating unit to estimate a marine vessel speed and a pitch angle of a hull of the marine vessel based on a propulsion force of a marine vessel propulsion device and an attitude of the marine vessel propulsion device and a judging unit, and a measuring unit to measure an actual marine vessel speed and an actual pitch angle. The judging unit judges the presence or absence of the abnormality based on at least one of a comparison result between the estimated marine vessel speed estimated by the estimating unit and the actual marine vessel speed measured by the measuring unit or a comparison result between the estimated pitch angle estimated by the estimating unit and the actual pitch angle measured by the measuring unit.
