PROBLEM TO BE SOLVED: To provide a stern duct capable of improving a hull efficiency without increasing the resistance of a hull even if a duct body is added to the hull, a design method for the stern duct, and a ship equipped with the stern duct.SOLUTION: A stern duct to be attached to the front of a propeller attached to the stern of a hull is characterized in that a duct body 11 is generally formed into an arc shape of an angular range of 180 degrees to 270 degrees. While the hull is viewed to the front from the back, the duct body 11 is attached to the stern by support means so that the duct center line Yd of the duct body 11 may have an inclination angle in the rotation direction of the propeller with respect to the propeller center line of the vertical direction of the propeller while the hull is being viewed from the back to the front.

    【課題】ダクト本体を船体に付加しても船体の抵抗を増加させることなく船殻効率を改善することができる船尾用ダクト、船尾用ダクトの設計方法、及び船尾用ダクトを装備した船舶を提供する。【解決手段】船体の船尾に取り付けたプロペラの前方に取り付けられる船尾用ダクトにおいて、ダクト本体11を180度から270度の角度範囲の略円弧状に形成し、船体を後方から前方視した状態でプロペラの上下方向のプロペラ中心線に対してダクト本体11のダクト中心線Ydがプロペラの回転方向に傾き角を有するように、ダクト本体11を支持手段にて船尾に取り付けたことを特徴とする。【選択図】図5
