Propulsion device for proximity twin-screw vessel having shaft bracket and ship

A propulsion device for a proximity twin-screw vessel having a shaft bracket, the propulsion device comprising:

• a port propeller and a starboard propeller installed at a stern hull;
• one rudder disposed at a center in a vessel widthwise direction of the stern hull or two rudders constituted by a port rudder and a starboard rudder in rear of the port propeller and the starboard propeller;
• and
• shaft brackets installed in front of the port propeller and the starboard propeller, respectively, and configured to rotatably support propeller shafts of the port propeller and the starboard propeller,
• wherein a distance between a tip end of a propeller blade of the port propeller and a tip end of a propeller blade of the starboard propeller at a center in the vessel widthwise direction is larger than 0 m and equal to or smaller than 1.0 m, and
• a rotational direction of the port propeller and the starboard propeller becomes an outer track rotating from the center in the vessel widthwise direction toward the outside over the port propeller and the starboard propeller.
