The invention discloses a follow-up symmetrical flap sail, and belongs to the field of ship and ocean engineering. Comprising a main sail assembly, flaps and a transmission mechanism, and the two symmetrically-arranged flaps are connected with the main sail assembly through the transmission mechanism; the main sail assembly comprises a main sail and a main sail shaft, and the main sail is connected with the driving module in the ship body through the main sail shaft; the two sail bodies are symmetrical about the plane where the wing chord of the main sail is located and embedded in the grooves in the two sides of the main sail; the folding and unfolding actions of the two flaps are controlled through the transmission mechanism; when the rotating angle of the main sail is 0, the two flaps are collected in the grooves in the two sides of the main sail, and the integral wing-shaped sail is formed; when the main sail rotates, the flap on one side rotates to the rear edge of the main sail in the same direction, an
