A combined type wind-wave-resistant ship comprises a hull and is characterized in that a deck of the hull extends towards two sides; a plurality of support bodies are arranged under the parts, extending towards the two sides, of the deck and are all provided with support points; and buoys are in coupling connection to all the support points. The deck extends towards the two sides, so that the width of the deck is increased. The multiple support bodies are arranged under the deck and are all provided with the support points, the buoys are in coupling connection to all the support points, in this way, the parts, extending towards the two sides, of the deck are supported, and the transverse stability of the hull is improved. Transverse connection rods are arranged between the hull and the support points, and thus the transverse firmness of the support bodies is enhanced. Through the design, wind-wave resistance of the hull is improved, meanwhile, the structure is relatively simple, the manufacturing cost is low, most domestic shipyards can produce the combined type wind-wave-resistant ship, the technical requirements and site requirements of manufacturing are lowered greatly, and the manufacturing cost is lowered more.
