ABSTRACT:
A sculling boat assembly is provided to control the traveling direction and drive a boat, and the sculling boat assembly installs a transmission mechanism on two hulls, connects an end of each transmission mechanism to a handle extended from the two hulls, connects another end of each transmission mechanism to a paddle rod extended from the tail of the boat, and connects an end of each paddle rod with an extension of a fin-shape member. Through the transmission of each paddle rod, a user applies a force onto each handle to drive the fin-shape member disposed on each paddle rod for the movements of pushing water outward and enclosing water inward, such that the water resistance is converted into a reaction by the soft and hard materials of the fin-shape member and its extension to drive the boat to move forward rapidly.
