PROBLEM TO BE SOLVED: To provide a boat navigation assist system adapted to appropriately produce alerts and alarms consistent with actual navigation circumstances of a small boat in a predetermined water region when a subject boat approaches a dangerous region.SOLUTION: Navigation assist apparatuses 200 are mounted individually on small boats 1, including a subject boat, navigated in a predetermined water region 2; and each detect a sharp turn of the corresponding boat 1 when it occurs, and send position information of the subject boat at that moment as sharp-turn occurrence position information to a server 500 via a base station 300 placed on land 4. The server 500 receives and collects the sharp-turn occurrence position information sent by each boat 1, determines on the basis of the accumulated data a danger level of each of mesh-like coordinate domains into which the predetermined water region 2 is divided, and updates and stores the danger level information. The navigation assist apparatus 200 of each boat 1 downloads the danger level information from the server 500 and displays it on a display; and alerts or alarms an operator concerned when the subject boat approaches a region with a high danger level.SELECTED DRAWING: Figure 4
【課題】所定海域における小型船舶の実際の航行状況に即して、自船が危険な領域に接近した場合に警告や警報を適切に行えるようにした操船アシストシステムを提供する。【解決手段】所定海域2を航行する、自船を含む複数の小型船舶1にそれぞれ操船アシスト装置200を搭載し、各船舶1で急転舵が発生した場合に、それを検知して、その時の自船の位置情報を、急転舵発生位置情報として陸上4の基地局300を介してサーバ500に送信する。サーバ500は、各船舶1から送信される急転舵発生位置情報を受信して収集し、その蓄積データに基づいて所定海域2をメッシュ状に分割した座標領域毎の危険度を判定し、その危険度情報を更新・保持する。それを各船舶1の操船アシスト装置200がサーバ500からダウンロードしてディスプレイに表示し、自船が危険度の高い領域に接近した場合には、操船者に警告や警報して知らせる。【選択図】 図4
