A multi-purpose catamaran and a method for building it using the means of tier

Abstract

A multi-purpose catamaran is disclosed in the present invention, comprising hulls and deck, wherein the hulls are two hulls, the central of the deck is arranged a movable deck, a detachable crane is set over the movable deck for hanging a fishing net or a fishing cage. The catamaran according invention can be easily disassembly and assembly, and expediently be carried and used. The fishing net or the fishing cage can be immerged in water for transiting live fish carried in it, can conveniently transfer to the deep water region for cultivating or to the shallow water region to disembark, removing the hoop can easily hoist it to the dock and can be easily transferred to a truck. The present invention has multi-purpose, except for using to retract and place fishing cage, to transfer aquatic products or personnel, or be as small-sized tow net, also can be used for selling, fishing etc. The present invention manufacturing method is simple, and can easily manufacture the catamaran without a model, suitable for fisherfolks to manufacture the catamaran by themselves, and the catamaran has lower cost.

Description

technical field [0001] The invention relates to the field of ships, in particular to a multipurpose catamaran and a stacked construction method thereof. Background technique [0002] The stability of the catamaran is excellent, but the structural strength is not as good as that of similar monohulls, and the hull is larger, difficult to disassemble, and inconvenient to transport, thus limiting its scope of use. A catamaran dedicated to fishermen. Fishermen generally use monohull boats, which is very inconvenient when picking and placing fish cages with aquatic products. When carrying passengers / cargo to distant sea areas or islands, the speed is slow and the fuel consumption is high, and it is inconvenient to get on and off the shallows. In addition, at present, most of the fiber boats need to use large molds to make them. The boats made by this method are expensive, occupy a large area for shipbuilding, have complex processes, heavy weight, and difficult transportation, wh...
