This invention relates to the field of marine auxiliary equipment technology, specifically to a swivel and a boat having the same. The swivel includes a shaft; multiple lifting mechanisms are evenly arranged around the shaft along its axial direction; each lifting mechanism can be deployed to form a lift fan with the shaft or retracted to form a first swivel section; multiple drag mechanisms are evenly arranged around the shaft along its axial direction; the multiple drag mechanisms and multiple lifting mechanisms are alternately arranged in the vertical direction; each drag mechanism can be deployed to form a drag fan with the shaft or retracted to form a second swivel section; when the lifting and drag mechanisms are deployed, and the input shaft of the generator is connected to the shaft, the airflow drives the lift fan and drag fan to rotate together, thereby generating electricity; when the multiple lifting and drag mechanisms are retracted, and the output shaft of the first drive motor is connected to the shaft, the first drive motor can drive the first and second swivel sections to rotate.
