Disclosed is a hull for a sea vessel having at least one pair of flow tubes mounted to the hull and extending substantially parallel to and symmetrically with the keel line of the hull below the water line. The flow tubes themselves are preferably of an elliptical cross-section having an inlet at the forward section of the hull and an outlet at the aft section of the hull for the flow of sea water therethrough. The flow tubes are movably mounted to enable the raising and lowering corresponding to the velocity of the hull through the water and the water conditions respectively. The sea vessel with the improved hull design is preferably propelled by an airscrew engine or a jet engine. |
