PROBLEM TO BE SOLVED: To provide a ship having a square sail formed with a hard sail which is capable of accommodating the sail to such an extent that the existence of the sail draws no attention when the sail is not required, securing a view in a congested sea area, improving performances of ship handling, the anchoring and the pier docking and undocking under strong wind, and reducing an aerodynamic resistance under head wind in the ship provided with a main engine, a propeller device driven by the main engine and the square sail formed with the hard sail arranged on a deck, and to provide a method for accommodating and developing the square sail.SOLUTION: A rotation mechanism 20 is provided on a root support part of a sail main body 11 of a square sail 10, an upper part of the sail main body 11 is supported by a wire 25 which passes through a pulley 24 disposed on an apex of a mast 23, upon accommodation of the square sail 10, the sail main body 11 is rotated around the rotation mechanism 20, is turned over and is loaded on a deck 2 and, upon development of the square sail 10, the wire 25 is wound by a wire winding device 26 disposed on the deck 2 and, thereby, the sail main body 11 is rotated around the rotation mechanism 20 and is erected.

    【課題】主機関及び主機関により駆動される推進装置と、甲板上に配置された硬帆で形成される横帆を備えた船舶において、帆を必要としないときに、帆の存在を無視できる程度まで格納できて、輻輳海域での視界の確保と、強風の下での操船、錨泊、離着桟に関する性能の向上と、向かい風の下での空力抵抗の低減を図ることができる硬帆で形成される横帆を備えた船舶及び横帆の格納及び展開方法を提供する。【解決手段】横帆10の帆本体11の根元支持部に回転機構20を設け、帆本体11の上部をマスト23の頂部に設けたプーリー24を経由するワイヤー25で支え、横帆10の格納時には帆本体11を回転機構20の回りに回転して転倒させて前記甲板2に載置し、前記横帆10の展開時には、甲板2上に設けたワイヤー巻取り装置26でワイヤー25を巻き取ることで、帆本体11を回転機構20の回りに回転して起立させる。【選択図】図14
