Problems solved by technology

In order to reduce the mutual interference and wave-making between the plates, at present, the main method is to increase the distance between the two plates. However, the increase in the distance between the plates will greatly increase the ship's construction cost

Embodiment Construction

[0008] a catamaran such as figure 1 , including two symmetrically arranged sheet bodies 1 and a connecting bridge 2 connecting the sheet bodies, the outer sides of the two sheet bodies are curved hulls, and the inner sides of each sheet body 1 adopt a linear hull in front of the midship 3, including the front end of the sheet body The same inner side of the bulbous bow 4 is a linear hull, and the inner side of each sheet adopts a curved hull behind the midship 3.

[0009] When the catamaran is sailing, the water flowing along the surface of the straight inner side of the two hulls is relatively straight, the waves are small, and the interference between the waves between the hulls is small, so the resistance of the boat is small. Under the condition of the same power, it can increase the speed of the ship. The straightness of the inner side of the sheet body also greatly reduces the inflow angle at the front end of the sheet body, which further reduces the ship's running resi...

Abstract

The invention discloses a catamaran. Each sheet body adopts straight line type boat case at the front inner side of a middle, and the curve-shaped boat case transition is adopted at the back inner side of the middle. The catamaran has a small flow inlet angle, in addition, the mutual interference of waves at the inner sides of the sheet bodies and the wave making are little, the boat running resistance is small, and the navigation speed is high. In addition, the space between the two sheet bodies can be small, and the building cost of the catamaran can be greatly reduced.

Description

technical field [0001] The invention relates to a ship structure, in particular to a catamaran ship structure. Background technique [0002] A catamaran is a hull made of two symmetrical hulls connected by bridges. In the existing catamaran, each piece of the body itself is also a symmetrical structure, and the waves generated on the inside of the two pieces of the body will interfere with each other and make waves, thereby increasing the resistance suffered by the forward movement of the ship. In order to reduce the mutual interference and wave-making between the plates, at present, the main method is to increase the distance between the two plates. However, the increase in the distance between the plates will greatly increase the ship's construction cost. Contents of the invention [0003] The present invention aims to provide a catamaran with less forward resistance and low construction cost. [0004] The catamaran of the present invention comprises two mutually sym...
