PROBLEM TO BE SOLVED: To provide a tailwind sailing direction display device which can display an optimal sailing direction according to wind direction and wind velocity, and a program.SOLUTION: A tailwind sailing direction display device 1 is equipped with: a wind direction acquisition part 11 for acquiring a wind direction indicated by an azimuth direction as an angle of a base line, which extends in a cross direction, with respect to a magnetic meridian; a wind velocity reception part 12 for receiving a wing velocity; a storage part 40 for storing a sailing angle table which stores a sailing angle formed between an optimal sailing direction when wind is blown along the base line and the base line every wind velocity; a sailing angle determination part 13 which determines a sailing angle in a wind velocity based said wind velocity with reference to the sailing angle table; a sailing direction azimuth calculation part 14 which calculates an azimuth of a sailing direction from the sailing angle determined by the sailing angle determination part 13 and a wind velocity; a display control part 15 which so controls as to display the azimuth of the sailing direction on an input/output part 30.SELECTED DRAWING: Figure 2

    【課題】風向と風速に応じて、最適な帆走方向を表示できる追風帆走方向表示装置を及びプログラムを提供する。【解決手段】追風帆走方向表示装置1は、前後方向に延びる基準線の磁気子午線に対する角度である方位で示される風向を取得する風向取得部11と、風速を受け付ける風速受付部12と、基準線に沿って風が吹いた場合に最適な帆走方向と、基準線と、の角度である帆走角度を、風速毎に記憶する帆走角度テーブルを記憶する記憶部40と、帆走角度テーブルを参照して、風速に基づき、当該風速における帆走角度を決定する帆走角度決定部13と、帆走角度決定部13で決定した帆走角度と、風向と、から帆走方向の方位を算出する帆走方向方位算出部14と、帆走方向の方位を入出力部30に表示する制御を行う表示制御部15と、を備える。【選択図】図2
