To provide a safe and inexpensive external thruster for moving a vessel horizontally.SOLUTION: This invention adopts a method for retaining a thruster 104 in dry space higher than the water line 116 such as an arm position 113 when an arm top is in a stored state; rotating in e.g. a rotational direction 114 with a hinge element 117 as center when in use and moved and installed underwater such as in an arm position 115 in standing state; and rotating a propeller attached to an electromotor rotational shaft by supplying power to the electromotor which is a component of the thruster 104, thereby generating propulsion in horizontal direction, as well as means for moving into water.SELECTED DRAWING: Figure 2
