In recently years, extraordinary propagation of water-weed such as Water Lettus and so on in waterway, river and reservoir has been serious problem. However, some removal activities by heavy machine and human-wave sweep has not given desired effect due to the limited activity area and low efficiency. In this study, a water-weed collecting ship with Archimedean screw, which is amphibious ship and can move and remove them regardless of bottom condition of river and reservoir and propagation condition, has been developed in order to solve the problem. In this paper, for the purpose of a development of a design guideline of Archimedean screw, an effect of pitch of Archimedean screw on thrust was experimentally investigated and compared with the simulation. Furthermore, the motion of the water-weed collecting ship with two Archimedean screws was investigated and die mechanism was clarified
