본 발명은 선박 및 그 제조방법에 관한 것으로서, 이종 재료를 접합하여 제작된 선박 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ship and a manufacturing method thereof, and more particularly, to a ship manufactured by joining different kinds of materials and a manufacturing method thereof.

선박은 사람이나 재화를 싣고 물 위를 운행하는 수상교통수단을 총칭하며, 필요에 따라 다양하게 구분될 수 있고, 사용목적에 따라서는 상선, 군함, 어선, 레저선박, 특수 목적선 등으로 구분할 수 있고, 크기에 따라서는 대형선(90m이상), 소형선(90m이하) 등으로 구분할 수 있으며, 속도에 따라서는 초 쾌속선(40knot), 쾌속선, 고속선(25knot이상), 일반선 등으로 구분할 수 있다.A ship is collectively referred to as a water transportation means that carries a person or a goods on the water. It can be divided into various kinds according to the necessity, and it can be classified into a commercial vessel, a warship, a fishing vessel, a leisure vessel, Depending on the size, it can be classified into a large line (over 90m) and a small line (less than 90m). Depending on the speed, it can be divided into a super rapid line (40knot), a rapid line, a high speed line (more than 25knot) and a general line.
