Catamaran

Abstract

The invention discloses a catamaran and relates to the technical field of ships. Each sheet body of the catamaran has the same structure; the catamaran comprises a bow area, a middle area and a sternarea; the bow area, the middle area and the stern area are in smooth transition connection with each other in sequence; the design of a cylinder bulbous bow can change the bow waveform generated by the catamaran during running at a high speed to form favorable interference; as a stem is of a plate type structure, and the horizontal sections of shell platings on the two sides are laminated on the stem in a V shape, it can be guaranteed that each sheet body has a flooding angle which is small as much as possible; a falling stem makes a waterline of a bow of each sheet body be in an unsymmetricalshape; when the catamaran runs at the high speed, more water at the front ends of the sheet bodies is forced to be shunted to the external side so that water flowing to the internal sides of the sheet bodies are reduced; and therefore, wave making interference between the two sheet bodies is also reduced; and the stern area adopts two concave kunckle lines which are gradually retracted in the lifting process to form integrated stern tower.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a catamaran. Background technique [0002] Due to its good stability, superior resistance performance, and large deck area, catamarans occupy a large market share among high-speed ships. [0003] At present, most catamaran hulls adopt a line shape transitioning from a deep V shape to a U shape from the bow to the stern. The seakeeping performance of this line type is not very good. In order to improve the seakeeping performance of catamarans, excellent ship types such as small waterplane area catamarans and wave piercing catamarans have appeared on the market, but these ship types also have their limitations. For example, the resistance performance of small waterplane area catamarans is limited. The load change has a great influence, and its damage stability is relatively poor. Therefore, there are few application examples in the commercial field. WPCs are widely used, but their...

In order to improve the seakeeping performance of catamarans, excellent ship types such as small waterplane area catamarans and wave piercing catamarans have appeared on the market, but these ship types also have their limitations. For example, the resistance performance of small waterplane area catamarans is limited. The load change has a great influence, and its damage stability is relatively poor, so there are few application examples in the commercial field

Wave piercing catamarans are widely used, but their hull structures are complex, and their construction and operating costs are relatively high
