The plurality of hulls 101 may be used to carry a cradle 102, and the cradle 102 may be used to carry cargo, batteries, and the like. In the description of the present invention, "a plurality" means two or more.

Referring to fig. 1, two hulls 101 are arranged in parallel. As shown in fig. 2, each hull 101 includes a buoyancy section 12 and a power section 14, and the buoyancy section 12 and the power section 14 are connected. Specifically, there are two power portions 14, one of the power portions 14 is connected to one end (e.g., the front end) of the buoyancy portion 12, and the other power portion 14 is connected to the other end (e.g., the front end) of the buoyancy portion 12. In other words, the buoyancy section 12 is connected between the two power sections 14. The power portion 14 has a drainage function, and the buoyancy portion 12 can be driven to move by drainage; further, by adjusting the drainage direction of the power portion 14, the power portions 12 at both ends of the buoyancy portion 12 can provide driving forces in different directions to the buoyancy portion 12, and further, the buoyancy portion 12 can be driven to move forward, backward, turn left, turn right, and the like.

For example, taking one hull 101 as an example, the description explains the process of adjusting the moving direction of the unmanned ship 100: when the unmanned ship 100 moves forward or backward, the power unit 14 can be controlled to be activated, and the hull 101 can be driven to move forward or backward. Such an operation may improve the mobility flexibility of the unmanned ship 100, and particularly, when the unmanned ship 100 is stranded, the unmanned ship 100 may be controlled to retreat according to the state of the unmanned ship 100, and thus the unmanned ship 100 may be automatically separated from the stranded state.

As shown in fig. 3 and 4, the power unit 14 includes a first end surface 111, a second end surface, two side surfaces, a top surface, and a bottom surface 112, where the second end surface, the two side surfaces, and the top surface are respectively formed as arc surfaces and arc-transition, so as to reduce the resistance of the unmanned ship 100 during navigation.
