| 20090211506 | Hull and steering mechanism for a marine vessel - A combined hull and steering mechanism for a marine vessel has a substantially rectangularly-shaped upper hull joined to a lower hull that is dual-tapered from its sidewalls to both its forward and aft portions. A directional thrust steering mechanism having a pair of vertical rudder blades positioned on either side of a conventional propeller extending from the centerline of the lower hull directs the water from the propeller, thus enabling the vessel to move more efficiently and with greater maneuverability in both forward and reverse directions. The dual-tapered hull permits a significantly better flow of water to and from the propeller and steering mechanism of the vessel, particularly when operating in reverse, thereby allowing the vessel to turn 360° in its own length. | 08-27-2009 |
| 20090288585 | LOW-FUEL-CONSUMPTION TRANSPORT SHIP - Transport ships having a relatively large structure over the water line, such as a pure car carrier, container ship and a passenger ship tend to receive the air resistance during the sailing. When sailing aslant against the wind, check helm had to be effected so far to cancel the swinging moment causing an extra increase in the underwater resistance. A low-fuel-consumption transport ship described has a structure over the water line, including a bow of a shape integral with the bridge of a hollow nearly semispherical to quarter-spherical shape or a partly cylindrical shape which is smoothly continuing to the stern to decrease the air resistance. The low-fuel-consumption transport ship further has a vertical tail incorporating a chimney and is rotatable on the uppermost stern deck to cancel the swinging moment in the air, without almost requiring check helm and, therefore, decreasing the underwater resistance. | 11-26-2009 |
| 20110120361 | FORESHIP ARRANGEMENT FOR A VESSEL OF THE DISPLACEMENT TYPE - A foreship arrangement for a vessel of the displacement type, which foreship consists of the part of the ship in front of the vessel's midship mark ( | 05-26-2011 |
| 20120255477 | METHODS AND DEVICES FOR PERSONAL WATER CRAFT - Jet-powered water craft have become popular recreational pleasure craft for people worldwide as well as providing rapid response in a water environment for life savers, police, customs, etc. However, once the throttle has been cut there is no braking or steering mechanism for such craft. Equally such braking or steering is limited at low speeds. Accordingly it would be beneficial to provide means for braking and/or steering such jet-powered water craft under low speed operation and/or when the throttle is cut. According to embodiments of the invention such mechanisms are provided whilst providing for ease of use during operation as well as beaching/launching/storage. | 10-11-2012 |
| 20130192505 | FULL FORM SHIP'S HULL WITH REDUCED WAVE MAKING RESISTANCE - The efficiency of a full form hull is improved by moving the position of the forward shoulder ( | 08-01-2013 |
| 20140165894 | Ship Including a Device for Recovering Floating Objects - A ship comprising a hull at the bow of which an opening is formed, and on each side of said opening a recovery device designed to recover floating objects and guide them towards said opening, each recovering device comprising: a rigid vane having meshes sized so as to not allow the floating objects to pass but to allow water to pass, said vane being designed to adopt a stowed position in which it is out of the water, a collection position in which it is immersed and disposed in a plane substantially perpendicular to the direction of the advance of the ship and upstream of the opening, and a recovery position in which it is immersed and disposed in a plane substantially parallel to the direction of advance of the ship and upstream of the opening, and a control device mounted on the hull, and on which said vane is mounted, and which comprises means for ensuring the passage successively from the stowed position to the collection position and then to the recovery position and from the recovery position to the collection position and then to the stowed position. | 06-19-2014 |
| 20150314836 | VESSEL WITH EXTENDIBLE RAMP - A water vessel is provided. The water vessel includes a hull, a deck, and a ramp. The hull has a front end, an aft end, a starboard side, a port side, a bottom, a bow at the front end, and a stern at the aft end. The bow is movable between a closed configuration and an open configuration. The deck is in the region of the bow. The ramp is located between the bottom of the hull and the deck in a retracted position. When the bow is in the open configuration, the ramp is movable to an extended position in which the ramp extends from the front end of the hull. | 11-05-2015 |
| 20220136196 | Systems, Apparatus & Methods for Remote Collection of Floating Debris - An exemplary system for collecting floating debris from a body of water may include at least one ingestion head positionable at or proximate to the surface of the body of water, the ingestion head including at least one intake opening and at least one exit port fluidly coupled together, the ingestion head further including a vacuum cavity surrounding the at least one exit port so that the at least one exit port can be maintained submerged in liquid throughout debris recovery operations. | 05-05-2022 |

| 20090107381 | Universal Depth Boat - The various embodiments disclosed and pictured herein illustrate a universal depth boat that is easy to operate and may be controlled by a single operator. A universal depth boat and hull design that comprises a hull having a bow, stern, sides, a V-hull portion and a flat bottom is disclosed. In the exemplary embodiment, a V-hull portion for spreading water is centrally located at a forward portion of the watercraft. The V-hull portion may include a keel as a forward apex, which forms a substantially perpendicular or vertical leading wedge with respect to the plane of water. The V-hull portion transitions to a flat bottom toward the stern. Accordingly, the watercraft will more easily traverse waves instead of riding over them, while the watercraft is simultaneously capable of accessing areas with extremely shallow water. | 04-30-2009 |
| 20100000455 | TRANSOM STERN HULL FORM AND APPENDAGES FOR IMPROVED HYDRODYNAMICS - An improved displacement hull form for ships and boats, in one of many possible embodiments includes a transom stern hull form ( | 01-07-2010 |
| 20140041567 | Variable Stable Drilling Barge for Shallow Water Service (Inland and Offshore) - The invention described herein teaches that one drilling barge can be employed in two different areas. The standard drilling practice requires two vessels to perform the same work as one drilling barge invention. Standard drilling rigs require that one unit will drill well locations in water depths of | 02-13-2014 |
| 114610300 | And specific midbody (e.g., waist, etc.) | 1 |
| 20110146555 | WATERCRAFT HULL AND ASSOCIATED METHODS - A watercraft hull includes a lower portion, an upper portion, and a strake positioned between the lower portion and the upper portion. The lower portion may include a bow portion having a v-shape defined by a keel and sidewalls extending upwardly therefrom to the strake and an aft portion having a tunnel formed therein. The aft portion may be defined by a pair of opposing sidewalls extending downwardly from the strake to a bottom portion. The tunnel may be defined by a pair of opposing tunnel sidewalls that extend upwardly from the bottom portion to a tunnel top having a center rib. The lower portion may also include a medial portion that transitions the bow portion to the aft portion. The medial portion may have a vacuum chamber extending between and transitioning the keel of the bow portion to the tunnel formed in the aft portion. | 06-23-2011 |
