[0032] Please refer to figure 1 , the present embodiment provides a speedboat 10 using a jet power device, including: a hull 110 , an engine 120 , a ducted propulsion device 130 , a cylindrical steering device 140 and a rudder 111 .
[0033] The hull 110 is the main bearing part of the speedboat 10, and is used for carrying people and installing other equipment.
[0034]Preferably, the size of the hull 110 is not limited. In this embodiment, the hull 110 can be a small flat-bottomed hull 110, specifically, the width of the boat can be 1.4m-2m (including 1.4m and 2m), and the height of the boat can be 0.7m-1.2m (including 0.7m and 1.2m), the length of the boat is 3m-5m (including 3m, 4m and 5m). In order to make the mass of the hull 110 as small as possible, it can be suitable for manual transportation to different usage occasions for emergency use. For example, the hull 110 made of aluminum alloy can be used, or the hull 110 of higher strength plastic can be used, and a mix...

[0055] Such as Figure 6 As shown, a speedboat 20 using a jet power device provided in this embodiment is different from the first embodiment in that the second end of the ducted shell 131 is provided with a smooth first angle turning portion 241, the angle turning part is an arc-shaped bending structure; one end of the steering device 140 of the speedboat 20 is provided with a second angle turning part 242, and the second angle turning part 242 is a smooth arc-shaped curved cylindrical structure.
[0056] Preferably, the connection 243 between the first angle turning portion 241 and the second angle turning portion 242 is a rotation connection, and the connection 243 is located in the vertical direction. The steering device 140 can swing left and right in the horizontal direction by using the joint 243 of the first angle turning portion 241 and the second angle turning portion 242 as a rotating shaft. The swing angle is not limited, for example, any angle between 0-180° (suc...
