To reduce an error to occur in a track control system even when an edited waterway is generated to be a new tracking waterway.SOLUTION: A waterway editing device includes: a position determination section for determining whether a position of an own vessel exists in a veering zone in a tracking waterway; and a way point generation section. The way point generation section performs: obtaining a new course where a center line along a course direction of the veering zone has contact with the new course at a contact point before the own vessel when determining the new course difference from a present course toward a second way point in a case where the own vessel exists in the veering zone and also it is determined that an editing waterway is generated; obtaining an intersection point of a new waterway straight line along the new course with a first zone straight line along the course direction in a first direct advance zone; generating a new first way point being the new first way point based on the position of the intersection point; and generating a new second way point at a position separated from the contact point when viewed from the own vessel on the new waterway straight line.SELECTED DRAWING: Figure 1

    【課題】編集航路を生成して新たな追従航路とする場合であっても、トラックコントロールシステムに生じるエラーを低減する【解決手段】追従航路のうち、自船の位置が変針区間にあるか否かを判定する位置判定部と、前記変針区間に前記自船があり、前記編集航路を生成すると判定された場合に、現在の第2ウェイポイントに向かう針路とは異なる新針路を決定するにあたり、前記変針区間の針路方向に沿った中心線と前記新針路とが前記自船よりも前方である接点において接する新針路を求め、かつ、前記新針路に沿った新航路直線と、前記第1直進区間の針路方向に沿った第1区間直線との交点を求め、当該交点の位置に基づいて新たな第1ウェイポイントである新第1ウェイポイントを生成し、前記新航路直線のうち前記自船からみて前記接点よりも離れた位置に新第2ウェイポイントを生成するウェイポイント生成部と、を有する。【選択図】図1
