| Number | Title | Issue Date |
| 7192322 | Line design and propulsion system for a directionally stable, seagoing boat with rudder propeller drive system A seagoing boat is driven by at least two rudder propellers and has a hull for transporting cargo or passengers. The rudder propellers are preferably embodied as electric rudder propellers. The hull has an approximately rectangular cross section amidships, to which ... | 03/20/2007 |
| 6893304 | Course-stable, fast, sea-going ship comprising a hull that is optimized for a rudder propeller A course-holding, high-speed, sea-going vessel having a hull which is intended to hold payloads or passengers and at least one rotatable, preferably electric, rudder propeller (POD) which is arranged gondola-like under the hull of the vessel and has, to supply it wi... | 05/17/2005 |
| 6058864 | Ship hull and vessel with such a hull A ship hull with bulb prow and with bottom which extends without sharp changes from the bulb to the square stern of the hull along continuously bent longitudinal lines and with hull sides which are inclined from the vertical plane from the waterline to th... | 05/09/2000 |
| 5598802 | Hull configuration A new displacement hull configuration providing for homogenous flow of water under the stern including side-hull bulges that are relatively constant in size from the bow to mid-ship and tapering off to about zero at the stern. Additionally, the hull is pr... | 02/04/1997 |
| 5280761 | Combined bulbous bow and sonar dome for a vessel To reduce the total ship resistance and to improve a propeller efficiency and cavitation performance due to the reduced thrust loading on the propeller for ships or vessels having a sonar dome or an equivalently shaped designs located below the baseline o... | 01/25/1994 |
| 5211126 | Ship or boat construction having three hulls A catamaran design has a third hull positioned between the conventional hulls. The third hull has a length equal to about two-thirds of the length of the conventional hulls, and a recess is formed in the underside of the deck aft of the third hull. The re... | 05/18/1993 |
| 5090352 | Bow foil Vessels with improved performance capability and methods for improving such performance and foils which may be associated with a vessel for providing this improved performance capability. Additionally, a method and device for improving flow through a micr... | 02/25/1992 |
| 4843989 | Ship's hull for small vessels and high speeds Ship's hull, characterized by the fact that the hull below the construction water line (C.W.L.) consists of a bulb-shaped displacement body extending approximately over the entire length of the ship, which is slim in the forebody, then becomes uniformly t... | 07/04/1989 |
| 4658746 | Seagoing vessel having a bulb A seagoing vessel is provided with a bow bulb composed of a main body, integral with the vessel's hull and a covering cowl member, which is swingable about horizontal hinges at its rear end. In fully loaded/stationary condition the top ridge of the cowl m... | 04/21/1987 |
| 4550673 | Hull construction for seagoing vessels A seagoing vessel comprises a hull having a forwardly projecting bulb at its bow. The bulb includes an upper periphery oriented substantially horizontally and exposed above the water surface when the vessel is stationary and in a fully loaded condition. A... | 11/05/1985 |
| 4323026 | Drag reducing structure to minimize vessel collision damage The drag-reducing bulbous bow of a seagoing vessel is provided with energy-absorbing structure including a controllably released fluid to reduce damage imparted by that vessel upon collision with another vessel or with an object.... | 04/06/1982 |
| 3946687 | Conical bulbous bow A novel bulbous bow for bulk carriers comprises a conical bulb with a faired nose, with the axis of the cone substantially parallel to the longitudinal axis of the ship. In a preferred embodiment the cone is a right circular cone and the faired nose is su... | 03/30/1976 |
