To provide a ship navigation support device capable of identifying a level to which attention should be paid in a range where there is the risk of collision.SOLUTION: A safe passing range in which an own ship and the other ship can safely pass is provided with the own ship as a reference, and a display device displays an attention area representing a range, which is calculated based on the safe passing range, in which there is the risk of collision of the own ship and the other ship. A range at a different attention level based on a distance/azimuth with the own ship as a reference is provided in the safe passing range, and a display control unit is provided for bringing a dangerous area calculated based on the range at the different attention level into a display mode of a different color/pattern from the attention area.SELECTED DRAWING: Figure 1
【課題】衝突の危険性がある範囲において、注意が必要なレベルを識別することが可能な船舶航行支援装置を提供する。【解決手段】自船を基準として自船と他船が安全に航過可能な安全航過範囲を設け、前記安全航過範囲に基づいて計算した自船と他船が衝突する危険性がある範囲を表す注意領域を表示装置に表示させ、前記安全航過範囲内に自船を基準とした距離/方位に基づいた注意レベルの異なる範囲を設け、前記注意レベルの異なる範囲に基づいて計算した危険領域を、前記注意領域と異なる色/模様の表示態様とする表示制御部を有する。【選択図】図1
