PROBLEM TO BE SOLVED: To rapidly cope with the change in the working contents, and to reduce the labor and the time by combining a plurality of floating units to form a hull. SOLUTION: First floating units 2, 2 are connected in the horizontal direction to second floating units 3, 3 using connectors to assemble a hull 1 of a mobile work boat. The first floating unit 2 is of rectangular flat shape, and formed as a hollow box-body whose inside is sealed. The second floating unit 3 is formed similar to the first floating unit 2, and a traveling body 4 is mounted on its side surface in an elevating/lowering manner through a hydraulic cylinder 5. Working machines such as hydraulic shovels 10, 11 are mounted on the hull 1 to effect the dredging works, etc.
