Abstract: A stern rudder fixing structure for fixedly connecting a stern rudder body to a stern rudder base is disclosed. The stern rudder fixing structure comprises a T-shaped bolt, a nut and a rotary rod, wherein the stern rudder body is detachably connected to the stern rudder base. The stern rudder comprises a stern rudder body, a stern rudder base and a fixing structure. The stern rudder and a paddle board provided by the disclosure are matched with a first insertion hole and a second insertion hole of the stern rudder base through the fixing structure, so that the stern rudder body and the stern rudder base are quickly assembled and dissembled in a time-saving and error-saving mode.
