Abstract:
There is provided a hull assembly for reducing water resistance on a ship hull and improving the maneuverability on said ship. The hull assembly is mountable on a pre-existing ship hull having a bow, and a stern. The hull assembly comprises a propeller chamber for enclosing at least one propeller positioned proximate the stern of the ship hull, and a plurality of ducts attachable to an outer surface of the ship hull. The ducts extend in a longitudinal direction from a front part of the bow to the propeller chamber. The ducts have a plurality of bow openings along the bow for the water to flow directly toward the rear part of the stern, each of the ducts comprising at least one stern opening near the propeller chamber. The propeller chamber comprises two opposed chamber sides; at least one chamber opening on each of the two opposed chamber sides; and a rear opening for each of the at least one propeller.
