As shown in figure 1, seats 1-3 are arranged on a cabin 1, the maximum number of passengers is 6, and protective fences 1-4 are arranged around the seats 1-3 to ensure the safety of the passengers.

Two channels 1-101 which run through the front and the back of the bottom of the cabin 1 are designed at the bottom of the cabin 1, so that the middle section of the bottom of the cabin 1 is of an M-shaped structure. The part between the two channels 1-101 is a main hull part which is used for draining water and providing buoyancy for the cabin 1; two feet of the two channels 1-101 are two surrounding walls of the cabin 1, similar to an apron of an air cushion landing boat, and play a role in sealing; the two channels are provided with water flow and air flow passages. Fig. 2a and 2b are schematic cross-sectional views of the middle and tail ends of two channels 1-101, respectively, and it can be seen that the two channels 1-101 have the same size, and the diameter of the middle position of the channel 1-101 is larger than that of the tail end, and is smaller than that of the front end of the channel 1-101. The two channels 101 are designed to improve the efficiency of navigation and to reduce the drag and draft during navigation.

Fig. 3 is a schematic view showing the flow of water flow and air flow in the channels 1-101 at the bottom of the cabin 1, and as can be seen from fig. 3A, the channels 1-101 can significantly reduce the wave making and the side splash, under the guidance of the rigid skirt, the channels 1-101 can "swallow" the first wave making and capture the air, and the rigid skirt can shield the splash caused by the central drainage body, so that the splash is controlled within the range of the channels 1-101, which greatly reduces the wave making effect of the planing boat, and is also beneficial to reducing the friction resistance and the pressure difference resistance. Fig. 3B shows the longitudinal flows of the channels 1 to 101, and as the channels 1 to 101 are continuously contracted in the longitudinal flow passage, the water flow and the air flow are compressed in the channels 1 to 101 to generate hydrodynamic lift force to lift the cabin 1, so that the cabin 1 "rides" on the water-air two-phase flow sucked by the channels 1 to 101, and the effect of slowing down the slamming of waves on the hull 1 can be achieved.

The tail part of the cabin 1 is symmetrically provided with two identical ducts 1-6. The section of the duct 1-6 is an airfoil shape, and the inner side of the duct is a convex surface, so that the suction force is generated by utilizing the low pressure area at the lip part of the duct. As shown in fig. 4, each duct 1-6 is internally distributed with eight-blade paddles 1-7, and the section of each paddle is also in an airfoil structure; fig. 6 is a sectional airfoil view of an eight-bladed blade and duct 1-6, where the larger area of the profile is the sectional profile of the duct 1-6 and the smaller is the sectional profile of the blade. Supporting sheets 1-9 are arranged between the propeller hubs 1-8 of the eight-blade propellers 1-7 and the inner walls of the ducts 1-6, preferably three supporting sheets 1-9 are adopted, the section of each supporting sheet 1-9 is an airfoil, and two ends of each supporting sheet are respectively connected with the hubs 1-8 and the inner walls of the ducts 1-6; the supporting sheets 1-9 are arranged in the ducts 1-6, so that aerodynamic force can be generated to offset reaction torque caused by rotation of the blades, a rotating flow field which is sensitive to forward incoming flow change is chopped, relatively stable air flow is formed at the tail parts of the supporting blades, and the propelling performance of the ducted fan is enhanced. The head of the hub 1-8 of the eight-blade paddle 1-7 is hemispherical, the middle part is cylindrical, and the tail part is conical. A rudder 1-10 is added at the tail part of the hub 1-8 to facilitate the control of the sailing direction, as shown in figure 5.

Fig. 7 shows the profile airfoil twist angle, the relative thickness and the chord length distribution of the blade, and it can be seen that both the twist angle and the chord length change nonlinearly, the blade tip-root ratio is 1.2, and the relative thickness R/R (R is the local section radius of the blade, and R is the maximum radius of the blade) is kept constant (no root thickening is adopted for the convenience of processing).

Fig. 8 is a flow chart and a pressure distribution on a symmetrical plane after CFD calculation of the single-duct fan, and it can be seen that a blade rotating at a high speed causes an air flow to wash down, a low-pressure region is above the blade, a high-pressure region is below the blade, and an upward positive thrust is formed by an up-down pressure difference. In addition, the mouth of the culvert lip is a low-pressure area to generate suction on the inner wall of the culvert, and the bottom end of the inner wall of the culvert is a high-pressure area, and the high-pressure area simultaneously generate extra positive thrust on the whole culvert.
