FIELD: shipbuilding; building of wind-propelled vessels. ^ SUBSTANCE: proposed wind-propelled vessel has sheet component held near hull by at least one shroud secured to sheet component at three points located at distance relative to one another. One shroud is secured on guide member mounted for motion on hull to change point of application of force from one shroud to hull in direction perpendicular and/or parallel relative to longitudinal axis of vessel hull. Sheet component may be made from elastic material. ^ EFFECT: enhanced efficiency; reduction of torques relative to longitudinal axis acting on hull. ^ 26 cl, 29 dwg
