To determine whether or not a marine vessel has abnormality.SOLUTION: A method for determining abnormality includes: estimating a vessel speed and a pitch angle of a hull 11 based on thrust force (thrust) of an outboard engine 12 and an inclination angle of the outboard engine 12; actually measuring the vessel speed and the pitch angle; and determining whether or not a marine vessel 10 has abnormality based on at least one of a comparison result between the estimated vessel speed and the actually measured vessel speed and a comparison result between the estimated pitch angle and the actually measured pitch angle.SELECTED DRAWING: Figure 3

    【課題】船舶の異常の有無を判定する。【解決手段】船外機12の推進力(スラスト)と船外機12の傾斜角度(姿勢)とに基づいて、船速および船体11のピッチ角が推定され、また、船速およびピッチ角が実測される。推定された船速と実測された船速との比較結果と、推定されたピッチ角と実測されたピッチ角との比較結果と、のうち少なくとも一方に基づいて、船舶10の異常の有無が判定される。【選択図】図3
