To provide a marine navigation support device capable of obtaining a marine navigation obstruction zone considering a margin.SOLUTION: A marine navigation support device for seeking a marine navigation obstruction zone from a relationship between the own ship and the other ship, comprises: a margin acquisition unit which acquires a margin indicating a degree of margin; and a calculation unit that obtains a marginal position which is a distance determined according to a marginal margin from at least one of bow and stern positions of the other ship in a target occupied space set based on a position of the other ship, obtains a collision course based on a position determined according to a motion vector of the other ship with the margin position as a reference, and calculates a marine navigation obstruction zone based on the determined collision course.SELECTED DRAWING: Figure 1
【課題】余裕を考慮した航行妨害ゾーンを求めることができる航行支援装置を提供する。【解決手段】自船と相手船との関係から航行妨害ゾーンを求める航行支援装置であって、余裕の度合いを示す余裕度を取得する余裕度取得部と、相手船の位置を基準として設定される目標占有空間における当該相手船の船首または船尾のうち少なくともいずれかの位置から前記余裕度に応じて定まる距離だけ離れた位置である余裕位置を求め、前記余裕位置を基準として前記相手船の運動ベクトルに応じて決定される位置に基づいて、衝突針路を求め、求められた衝突針路に基づいて航行妨害ゾーンを算出する演算部と、を有する。【選択図】図1
