440079000 | Propeller arrangement | 8 |
20090233500 | FLOATING STRUCTURE HAVING PROPULSIVE DEVICES FOR MOVING THE SAME WHILE SAILING AND MOORING - Disclosed is a floating system. The floating system comprises a floating body, a first propeller and a second propeller. The first propeller is pivotally secured to the floating body. The second propeller is pivotally secured to the floating body and distanced from the first propeller in a first direction and in a second direction perpendicular to the first direction. The first and second directions are generally parallel to a surface of water on which the floating system floats. | 09-17-2009 |
20120071046 | PROPULSION DEVICE OF SHIP - A propulsion device of a ship is provided with a port side propeller, a starboard side propeller, a port side propeller axis and a starboard side propeller axis. The port side propeller axis extends backwardly from the hull stern and is connected with the port side propeller. The starboard side propeller axis extends backwardly from the hull stern and is connected with the starboard side propeller. When the propeller diameters of the port side propeller and the starboard side propeller are Dp, the distance between a propeller wing tip of the port side propeller and a propeller wing tip of the starboard side propeller is equal to or more than 0 and equal to or smaller than 0.5 Dp. | 03-22-2012 |
20120214368 | THROUGH-HULL SUPPORT FOR STEERING AND PROPELLING A BOAT AND BOAT EQUIPPED WITH SUCH A SUPPORT | 08-23-2012 |
20150336649 | DEVICE FOR HOLDING A MOTOR AND A PROPELLER, AND RELATED DEVICES, SYSTEMS AND METHODS - A device for holding a motor and a propeller includes a body operable to hold a motor that, when coupled to a propeller and a power source, is operable to rotate the propeller. The device also includes a mount operable to releasably fasten the body to a personal-sized watercraft. With the mount, the device (and thus the motor and propeller that the device holds) may be releasably fastened to any personal-sized watercraft, such as a kayak, a surfboard, an inflatable paddleboard, and a non-inflatable paddleboard. The body includes a cavity configured to receive the motor such that, when the motor is disposed in the cavity, the body holds the motor. The body also includes a conduit configured to hold a power cable that, when coupled to the motor and the power source, provides power from a power source to the motor. | 11-26-2015 |

20080200082 | Jet Pumping Device - A propulsion or pumping device which includes two counter-rotating shafts ( | 08-21-2008 |
20110130056 | PROPELLER POD - The invention relates to a propeller pod ( | 06-02-2011 |
440082000 | Supporting strut | 2 |
20080220671 | STERN DRIVE, IN PARTICULAR FOR TWIN-PROPELLER BOATS - A stern-drive unit for boats with an inclined hull, wherein the mechanical units are separated from the supporting structure, which is made in the form of a structure ( | 09-11-2008 |
20120302114 | Emergency Drive Unit for Water Vessel - A collapsible and disconnectible for storage yet extending for use emergency motor drive unit for a boat. A motor is secured to a hollow drive-shaft pipe segment. Another pipe segment is attached to the end of that pipe segment and has a propeller at its end. A drive shaft of the motor is coupled to the propeller by flexible tubing passing through the hollow bores of the pipe segments. A third, and possibly fourth and fifth, pipe segment(s) is(are) provided between the other two segments to extend the length of the overall device. At least one pipe segment has a vertical support post which allows the device to be selectively held in the receptacle of an anchor light receptacle, when needed. A clamp block and ball swivel allow for rotational, lengthwise, and angular movement of the pipe segments to adjust the motor and the propeller to maximize efficiency of use. | 11-29-2012 |
