Fins to control angular travel of sailboats and wake control
InactiveUS20080257245A1Avoid high pressureIncrease speedVessel movement reduction by foilsVessel safetyFlight vehicleAirplane
As Aileron (fin) is to airplanes and aqualeron is to ships, a device with fins position on both sides of the keel in a horizontal position where a set of gears controls the fin on one side in a downward arc and the other side in an upward arc providing a controlled below water force to maintain any arc of travel on a sail boat, or as a hydrofoil. A set of fins positioned on the bottom of a sailboat eliminating the keel. A set of fins positioned at the bow of a motor boat providing a downward force of the bow. A set of fins on either side of the stem of a power boat, when activated, swing out directing water to the rear of the boat filling the cavity created by the boat to eliminate the wake. A set of fins on both sides when opened to a tube allowing a force of water to enter and empty at the rear of the boat filling the cavity with instant water thereby controlling a wake free operation.

Electrical energy from live loads
InactiveUS20050193728A1Improve efficiencyReduce friction lossFluid couplingsMachines/enginesWorking fluidGear wheel
A group of devices and machines for converting the mechanical energy of live loads into electricity. A generator is operated by gears which in their turn are operated by a Bourdon tube or similar-acting device fed by working fluid in a pipe from a reservoir. The reservoir walls are impacted by a choice of the rolling weight of a motor vehicle, the bending force on some object and / or by a decompressing force on the working fluid. The invention is applied to roadways, buildings, sailboats, cars with internal combustion engines, elevators, ships and bridges. If the varying impacts are caused by wind or subsurface ocean currents a new type of diverging nozzle is used to magnify pressure input. By using the invention pressure waves are used to transfer energy with minimal movement of working fluid, minimizing friction and other losses.

The present invention involves a tracking antenna system with no moving parts that extends the range of wireless mobile links 16 to 256 times the range of regular omni-directional whip antennas. The antenna system comprises an array of antenna segments arranged in a sphere or circle, or other suitable geometry. Each antenna segment includes one or more antennas connected and combined in parallel. Each antenna segment feeds a tuner and subsequent diversity electronics that optimizes both the transmission and reception in order to achieve the best possible range. The antenna system can be used from unmanned air, ground, and surface vehicles to mobile ground stations in motion, as well as between flying planes, moving vehicles, sailing boats, or any combination thereof. The system may be expanded further to many more levels of architecture as required. For example, this system may be expanded to a Level 2 diversity engine combination of any number and type of Level 1 antenna array units depending upon the diversity expansion required and the criteria for Level 2.

The invention discloses an all-day long-voyage unmanned sailboat. The unmanned control sailboat is composed of a ringtail, a main boat hull, a keel, a ballast, an aerovane, a wind surf rotating mechanism, a solar cell panel, a cell, a related processor, a sensor and other devices. The boat type is correspondingly modified by a conventional boat, so that the boat is more suitable for unmanned control operation. Due to the fact that the unmanned boat adopts wind as power, and the solar cell is arranged, compared with other unmanned boats, the working time is greatly prolonged, and all-day long-voyage work can be performed. The unmanned sailboat is low in building and using cost, long in working time, capable of being used for marine environment exploration, water surface patrolling and othertasks, and reliable monitoring of large-region seas can be achieved intelligently and automatically with low cost.

Line handling winch for sailing yachts
InactiveUS7717402B2High strengthSmall diameterFilament handlingWinding mechanismsElectric power systemEngineering
A power or manually operated winch mechanism for handling the running rigging lines of a sailing yacht. The winch includes a winding drum, operating in conjunction with a level wind mechanism, which winds and stores the line during line retrieving operations and controllably releases the line when desired. Novel level wind features enable the lines to be appropriately tensioned during retrieval, to assure proper windup of the line in organized coils on the drum. During line release, the line is placed under tension by the level wind mechanism and thus positively drawn from the unwinding winch drum even when the line is not under load from the sail to which it is attached. The arrangement enables lines to be automatically released from one winch and retrieved on a second which, under a common control, as when tacking or resetting the sails of a yacht, all without the necessity of any physical line handling by crew members, resulting in a significant improvement in the safety and convenience of the crew. The new winch mechanism preferably includes a novel alternate arrangement for manual operation of the system in the event of a failure of the power system.

Wireless immersible anemometer for sailboats
ActiveUS20160370399A1Additional strengthOffset effectNavigational aid arrangementsVessel partsWind sensorElectronics
A machine is disclosed for wind sensing on sailboats. Wind is important for sailing, but sailboats lean away from the wind when under sail. Vertical wind angles reduce the accuracy of existing anemometers. The cup blades disclosed here do not lose rotation speed when heeling over. Since it is now easy to have a sophisticated chartplotter display on a mobile device in waterproof case even on small boats, this waterproof wind sensor is a wireless “appcessory” that can talk to smartphones, tablets, computers, e-readers and marine electronics. The circuit board is encapsulated and is itself the wind direction arrow. A fluxgate compass on the circuit board provides wind direction. The apparatus is solar-powered, so there is no wiring to install or chafe. This allows a further inventive step for raising the anemometer using the mast track without needing to climb up or lower the mast.
