In some embodiments, the head end 11 in cabin 10 may be alternatively provided as transparent on the whole.In cabin 10, near head end 11 is leaned on Be provided with operator seat 102 and station 103 at hatch door 101, operator seat 102 is taken for personnel, and station 103 can be used for manipulating The catamaran.

The lower surface 15 in cabin 10 is arranged in and respectively close to the left end in cabin 10 13 and the right side in two single hulls 20,30 End 14.Cavity is set in single hull 20,30, when the catamaran is placed in water, can be used for generating buoyancy.In general, the catamaran Static stop in water when water line on single hull 20,30, and the lower surface 15 in cabin 10 is located on the water surface.Cause And during navigation, between the lower surface 15 and the water surface in the cabin 10, there are gaps, pass through for air-flow.

Along the section in navigation direction in wing, the head end 11 in the cabin 10 is greater than tail end 12 in the cabin 10.Such as Fig. 2 Shown in, 11 round blunt of head end in cabin 10, tail end 12 is sharp, arc-shaped, the upper surface of upper and lower surface 16,15 in the cabin 10 16 protrusions are more, and lower surface 15 is relatively flat.When the catamaran navigates by water in the water surface, air-flow head-on flows through the upper of cabin 10 Lower surface 16,15 is divided into two strands up and down, behind cabin 10, is overlapped again at one in tail end 12.Due to the upper table in cabin 10 16 protrusion of face, flows through the channel narrows of the air-flow of upper surface 16.According to the principle of continuity and Bernoulli's theorem of air-flow, upper table The pressure in face 16 is smaller than the pressure of lower surface 15, so that atmospheric pressure suffered by upper surface 16 is smaller, it is big suffered by lower surface 15 Atmospheric pressure is larger, and upper surface 16 becomes suction surface, and lower surface 15 becomes pressure face, existing pressure between upper and lower surface 16,15 Official post catamaran generates dynamic lift during navigation, can reduce the resistance that hull navigates by water in water, increases the speed of a ship or plane.

Further, wing flap 40 is arranged in the tail end 12 in the cabin 10.With reference to Fig. 3, wing flap 40 is arranged in tail end 12 And it is located between two single hulls 20,30 of lower surface 15.Engine (not shown) is set in single hull 20, the engine The discharge directions of exhaust pipe 21 are towards the lower surface of the wing flap 40.When engine sprays air-flow, wing flap 40 forces engine The air-flow changed course of ejection exists, and the reaction force of this air-flow can also increase the dynamic lift of catamaran, and then reduce resistance, increase boat Speed.

The single hull 20,30 of catamaran and cabin 10 etc. are all made of high-performance composite materials and are made, and the row of engine The tail gas that tracheae 21 is discharged has the characteristics that high temperature, thus the wing flap 40 is needed using high-temperature resistant composite material.
