Abstract

PURPOSE: To enable to easily spread or shorten a sail main body by a structure wherein the sail main body is transversely divided and a rotating device is equipped at the connecting part.
CONSTITUTION: The profile sail main body Ea is transversely divided into three unit sails Ea1, Ea2 and Ea3 rotatably connected with one another and the rotating device 6 is equipped at the connecting part. In order to shorten the sail main body Ea, a locking device 5, which secures unit sails Ea1, Ea2 and Ea3 one another, is released and the rotating device 6, which joins the respective divided unit sails with one another, is pivoted so as to be able to shorten the unit sails from above to below.
