Abstract

PURPOSE: To improve air force performance and sailing performance to all the available direction of wind and simplify sailing in such a way that wing-shaped sail is made developably divisible into two by the center line in the direction from the front end part to the rear end part in order to take the two as transverse sail and wing-shaped sail for their advantage.
CONSTITUTION: Wing-shaped sail 1 is integrated by sail main body parts 2A, 2B, and auxiliary sails 3A, 3B, they are symmetrical to the center line from the front end part 4 to the rear end part, and in shape of wings. The sail main body parts 2A, 2B are fitted to the opening and closing center axis 7 which penetrate the front end part in the longitudinal direction, and the auxiliary sails 3A, 3B, are fitted at the rear end of the sail main body parts and freely rotatably by respective rotatable center axes 8A, 8B. The opening and closing center axis 7 is supported through a plurality of bearings and freely rotatably on the sail mast 9 near the air force center position. This can rotatably driven system which provides various transferring mechanisms in response to the direction of wind.
