| 20090158983 | Yacht and Ballast Assembly Therefor - A yacht having an adjustable ballast assembly comprising a ballast, an elongated hollow ballast guide mounted to the hull of the watercraft to extend transversely of the hull, the ballast being located within the guide and there being means for selectively moving the ballast longitudinally of the guide between respective opposite end positions in which at least part of the ballast is located laterally outwardly of the hull. The elongated guide may be located within an outer hollow guide and mounted for longitudinal movement relative to the outer guide so as to be capable of projecting telescopically from opposite ends of the outer guide. | 06-25-2009 |
| 20090288586 | ADJUSTABLE KEEL FOR A SAILBOAT - A sailboat, which include an extendable keel having a moveable inner member positioned within a fixed keel and a control system for lowering or retracting the inner member. | 11-26-2009 |
| 20110155034 | BALANCE MAINTAINING EQUIPMENT FOR FLOATING BODY - A balance maintaining equipment for a floating body includes a driving device for rotating a driving shaft; a first eccentric rotating body positioned at one side of the driving device and connected to the driving shaft to rotate around the driving shaft by the rotation thereof; and a second eccentric rotating body positioned at the other side of the driving device and connected to the driving shaft to rotate around the driving shaft by the rotation thereof, while having a phase difference of 180 degrees from the rotation of the first eccentric rotating body. The balance maintaining equipment generates the moment in the opposite direction to the roll of the floating body. Furthermore, when the roll period of the floating body is changed, the balance maintaining equipment varies the angular velocity of the driving shaft to interwork with the roll period of the floating body. | 06-30-2011 |
| 20110297064 | ADJUSTABLE KEEL FOR A SAILBOAT - A sailboat, which include an extendable keel having a moveable inner member positioned within a fixed keel and a control system for lowering or retracting the inner member. | 12-08-2011 |
| 20120125246 | SELF-CONTAINED ECOLOGICAL DYNAMIC BOAT PITCH AND ROLL TRIM SYSTEM BY ALTERATION OF THE HULL WATER FLOW - The self contained ecological dynamic boat pitch and roll trim system by alteration of the hull water flow, of this invention consists of a main body ( | 05-24-2012 |
| 20120167812 | Wake Shaping System - The disclosure describes, in part, apparatuses and methods for shaping a wake of a water ski boat. Embodiments of wake shaping systems fixed to portions of a ski boat configured to heel a ski boat towards a starboard side and/or a port side of the ski boat. The wake shaping system comprising a ballast selectively positioned a distance above a waterline of a ski boat, and a distance from a pylon removeably fixed to a portion of the ski boat. | 07-05-2012 |
| 20140014015 | ACTIVE HEAVE COMPENSATION SYSTEM AND METHOD - An active heave compensation system comprises a motor generator to interact with a load so as to drive the load in a first part of a heave motion cycle and to regenerate at least part of energy with which the load has been driven in a second part of the heave motion cycle, and an electrical storage element for storing the regenerated energy. The active heave compensation system further comprises a power supply electrically connected to the motor generator and the electrical storage element for providing electrical power to at least the motor generator, and a control unit configured to control the power supply substantially in synchronism with the heave motion. | 01-16-2014 |
| 20140033961 | MOBILE BALLAST DEVICE - The present invention discloses an inside mobile ballast arrangement for sailboats, said arrangement using a dense material and being preferably in a watertight/gas-tight compartment, the whole system on low friction bearings and being close to the bottom of the hull, this arrangement being able to move longitudinally from front to rear and vice versa, along the X axis, independently or simultaneously with a perpendicular displacement, i.e. from port to starboard and vice versa, along the Y axis. | 02-06-2014 |
| 20140202367 | Weight Distribution Device and Method for Modifying Wake - The present invention is a device mounted on a watercraft that creates a method of systematic weight distribution, which modifies a vessel's wake as it travels through water. The device uses systematically moveable ballast object(s) that are supported in a variety of positions along a specified path. As a ballast object is selectively moved towards a specific extremity of a watercraft, it causes that side or end to sink deeper in the water, and raises the opposing side or end, thus controlling or influencing the vessel's relative position on a body of water. When the watercraft is operating at higher speeds, the invention's ability to control the vessels' position allows an operator to selectively control the shape, size and slope of the watercraft's wake, as referenced in the disclosed method. | 07-24-2014 |
| 20140311393 | Vessel, Motion Platform, Method for Compensating Motions of a Vessel and Use of a Stewart Platform - A method for compensating for motion of a boat as it floats on water includes measuring the motion of the boat relative to another element in an area surrounding the boat, generating a driving signal for driving actuators operatively associated between the boat and at least one carrier based on motion of the boat, driving the actuators to hold the at least one carrier substantially stationary relative to the element based on the driving signal and relieving weight on the actuators by at least partially bearing the weight of a load and the at least one carrier by an at least partially passive pressure element. | 10-23-2014 |
