A method of propelling ship by controlled vector direction of propulsion includes the following steps: mounting symmetrically braces for upholding the hull; mounting at the lower portion of the braces the propellers with its angel adjustable between the ship forward direction and the propeller propulsive force direction; and adjusting the said angle for resulting in the level propulsion vector and/or the vertical propulsion vector, the level propulsion vector to come into being level propulsive force for propelling the ship forward and the verticality propulsion vector comes into being vertical propulsive force for lifting the hull away from the water. |
