Abstract
PURPOSE: To enable to give the optimum camber to a profile sail main body by a structure wherein the profile sail is longitudinally divided and as well as respective unit sails are rotatably connected with one another.
CONSTITUTION: The profile sail main body Ea is divided in the same direction as the direction of a mast 5 into three unit sails (a main sail 1, a fore sail 2 and an aft sail 3) rotatably connected with one another and equipped with rotating devices 6 and 7. The respective unit sails 1, 2 and 3 are respectively symmetrical and form as a whole a single symmetrical profile when their center lines are coincided with one another. When the generation of a large lift with said profile is advantageous in spite of a small increase of drag followed, the fore sail 2 and the aft sail 3 are rotated by means of the sail rotating devices 6 and 7 located at before and after the main sail 1 in order to give the profile the optimum camber as the whole sail. At this time, a more larger lift can be generated by blowing the energy of wind into the boundary layer at the back side of the sail main body Ea to prevent the air flow from separating with a straightening sail 4 or 8 pulled out at the back pressure side.
