20070082564 - Watercraft: A watercraft is controllable by either a main station or a substation. A main-side remote control device is disposed in the main station. A sub-side remote control device is disposed in the substation. An outboard motor for generating propulsion force is controlled by the main-side remote control device or the... Agent: Knobbe Martens Olson & Bear LLP

20070082565 - Watercraft: A watercraft includes a remote control device disposed on a side of a hull for maneuvering the watercraft, and a plurality of outboard motors disposed on a side of a stem of the hull for generating thrust under control of the remote control device. A remote control body of the... Agent: Knobbe Martens Olson & Bear LLP

20070082566 - Boat: A boat can be provided with an electrically controlled outboard motor, or other type of propulsion unit, for producing thrust according to an operation of a remote control unit provided in a hull of the boat. The remote control ECU which can output a remote control operation signal can be... Agent: Knobbe Martens Olson & Bear LLP

20070082567 - Boat: A boat can include batteries, a generator, a remote control unit provided in a hull, and an outboard motor controlled through the remote control unit so as to generate thrust. The batteries and the generator can be connected to the remote control unit and the outboard motor via power supply... Agent: Knobbe Martens Olson & Bear LLP

20070082568 - Jet-propelled watercraft: A jet-propelled watercraft capable of maintaining a propulsion force required for a turn made at the same time as closing of a throttle valve. The jet-propelled watercraft has an auxiliary intake valve and an ECU. The auxiliary intake valve in an intake pipe opens/closes an auxiliary intake passage to bypass... Agent: Birch Stewart Kolasch & Birch

20070077829 - Device and method for controlling trimming flaps on a watercraft, as well as a watercraft having a corresponding device: A device for controlling trimming flaps (12, 13) of a watercraft (10), preferably having two trimming flaps (12, 13) and in each case at least one hydraulically operated for adjustment of the inclination angle (15) of the associated trimming flap (12, 13). The invention provides that the or each hydraulic... Agent: Powell Goldstein LLP

20070077830 - Power generation, distribution, and on-board power supply system for low-emissive surface marine (navy) ships of different classes and sizes: Disclosed is a power generation, distribution, and on-board power supply system for low-emission surface marine (navy) ships of different classes and sizes.
