Patent number: 8381584Abstract: A model hull testing method, platform, and system are disclosed that acquire model hull performance data about one or more hulls in an open-water environment, preferably testing two hulls simultaneously as they encounter essentially the same sea state. Avoiding tow-tank testing by providing a powered watercraft as an open-water testing platform, the method proceeds by supporting the model hulls on the testing platform, so they float in outboard positions, and then by acquiring data about hull performance as the testing platform and model hulls move together through an open body of water. A complement of data acquisition components acquires digital and analog data about the testing environment and model hull performance, preferably including platform motion, time and location information, wave characteristics, apparent wind speed and direction, and model hull drag and motion, with all data being recorded on an onboard laptop computer for later processing and analysis.Type: GrantFiled: July 25, 2011Date of Patent: February 26, 2013Assignee: M Ship Co., LLCInventors: Charles W.

Patent number: 7093553Abstract: A watercraft with at least one onboard propulsion engine includes at least two hulls and a wing-like deck structure spanning the two hulls (a floating wing). Port and starboard skirts combine with the deck structure to form port and starboard planing channels. The deck structure includes an upwardly facing surface that slopes downwardly toward an aft end of the deck structure in order to provide aerodynamic lift. Preferably, a speed-responsive exhaust proportioning system vents exhaust at vertical steps in planing surfaces on the hulls to reduce drag, increase lift, and reduce thermal signature. One embodiment includes hinged laterally extending deck extensions that an operator can raise to reduce vessel breadth during docking, upwardly extending barriers on the deck extensions that reduce the escape of wind laterally, and hinged flap structures disposed rearwardly that enable an operator to adjust vessel trim.Type: GrantFiled: May 23, 2005Date of Patent: August 22, 2006Assignee: M Ship Co., LLC.Inventors: Charles W.

Patent number: 6983713Abstract: A watercraft with a propulsion engine includes at least one hull having an underside. A dual exhaust system includes a first exhaust conduit defining a first exhaust flow path leading to the underside (e.g., a step in a planing surface on the underside) and a second exhaust conduit defining a second exhaust flow path to atmosphere. One embodiment is self proportioning. In another embodiment, an onboard proportioning system varies first and second proportions of the exhaust flowing through respective ones of the first and second exhaust conduits according to exhaust back pressure. First and second valve mechanisms selectively restrict the first and second exhaust flow paths under computer or manual control according to pressure sensed by a back-pressure-sensing component in order to thereby direct the exhaust in desired proportions for enhanced operating characteristics and reduced thermal signature.Type: GrantFiled: October 4, 2004Date of Patent: January 10, 2006Assignee: M Ship Co., LLC.Inventors: Charles W.

Patent number: 6951180Abstract: A canting ballast twin foil (CBTF) sailing yacht constructed according to the invention includes a sailing hull, a ballast, a ballast-supporting structure, and an onboard ballast drive system. The ballast drive system moves the ballast in order to vary the counter-heeling force it produces underway. Twin foils that depend downwardly from the hull in positions fore and aft of the ballast provide leeway and steering control. An onboard main engine drive system provides power, either directly by suitable mechanical coupling or indirectly through charging of the battery/electric system, for one or more of a canting system, a leeway, and/or steering control system. The onboard main engine drive system may also power a yacht-propelling propeller.Type: GrantFiled: March 4, 2004Date of Patent: October 4, 2005Assignee: CBTF Co.Inventors: Charles W.

Patent number: 6314903Abstract: The present invention relates to a watercraft having a wave suppressing “M-shaped” hull design. The hull comprises a central displacement body flanked by two downwardly extending outer skirts. The outer skirts are attached to the displacement body by planing wings having wing channels. The bow wave is directed into the wing channels, thereby increasing planing efficiency and reducing the effect of such waves on other boats and the shoreline. One embodiment takes the form of a twin-hull catamaran with two M-shaped hulls and four arcuate channels for containing the spiraling bow waves from the two central displacement bodies, thus to increase lateral stability and to suppress boat waves to protect nearby boats and structures at the water/land interface.Type: GrantFiled: December 27, 2000Date of Patent: November 13, 2001Assignee: Mangia Onda Co., LLCInventors: Charles W.

Patent number: 5622130Abstract: High performance sailing yacht designs are disclosed based on a keelless sailing yacht concept having dynamic gravitational ballast which is laterally movable for heeling resistance which ballast replaces a function of the standard keel. A keelless yacht of this type is disclosed with an adjustable flap mounted on an elongated strut from which the ballast is suspended below the hull to generate a variable heel hydrodynamic control force independently of the counter-heeling effect achieved by the ballast. The foregoing features enhance the effects of disclosed improvements and modifications to hull design in having a duplex form, with upper and lower hull shapes, the lower of low drag shape, and of reduced section, while the upper hull extends laterally abeam from the lower hull to define reserve buoyancy, added accomodation, and surfaces adapted for hydroplaning when the yacht is at a controlled angle of heel.Type: GrantFiled: May 22, 1995Date of Patent: April 22, 1997Assignee: Dyna-Yacht, Inc.Inventors: Alberto A.

Patent number: 3958947Abstract: A process and apparatus for hydrometallurgical leaching of unseparated, crushed mineral ores using a vessel having liquid stream forming nozzles in the lower portion thereof which operate to direct a stream of leaching liquid into solids in the lower portion of the vessel and to create a highly agitated interaction zone above which solids are settling under gravity and through which liquid from the lower portion rises upwardly in counter-current flow. The vessel is sufficiently high that an overflow of low solids content liquid is taken from the top. Outlets, as for example discharge piping or sumps, are provided in the bottom of the vessel for the controlled removal of solids therefrom. In multistage operation, the solids content of the overflow liquid is removed and the liquid content of the underflow is removed and combined to yield a mineral pregnant liquor which serves as the leaching liquid for a preceding stage where less depleted solids are being processed.Type: GrantFiled: October 29, 1974Date of Patent: May 25, 1976Assignee: Marcona CorporationInventors: Charles W.
