The higher the angular momentum, the greater the resisting force of the gyro to external torque (in this case more ability to cancel boat roll). A gyroscope has three axes: a spin axis, an input axis, and an output axis. The spin axis is the axis about which the flywheel is spinning and is vertical for a boat gyro.
The bridge of the freighter shown here has two steering stands. This redundancy is a safety measure in case one of the steering mechanisms that control the ship's rudder fails. A helmsman or helm (sometimes driver or steersman) is a person who steers a ship, sailboat, submarine, other type of maritime vessel, airship, or spacecraft.
Diagram of the steering gear of an 18th- to 19th-century sailing ship [3]: 151 Helm of TS Golden Bear. A ship's wheel is composed of eight cylindrical wooden spokes (though sometimes as few as six or as many as ten or twelve depending on the wheel's size and how much force is needed to turn it.) shaped like balusters and all joined at a central wooden hub or nave (sometimes covered with a ...
Sailors stand lee helm and helmsman watch. Traditionally, two stations are on the bridge of a ship for controlling the vessel's maneuvers: the helm, which uses a wheel (or touchscreen equivalent) to send signals to control the position of the rudder or rudders, and the lee helm, which traditionally inputs speed commands by operating an engine order telegraph to send engine commands to the ...
The fundamental cause of "helm", be it weather or lee, is the differential between the center of effort of the sail plan to the center of lateral resistance of the hull. If the center of pressure is astern of the center of lateral resistance, a weather helm, the tendency of the vessel to want to turn into the wind, or to weather-vane, will result.
Cold and flu season is upon us. Cases are jumping across the country, the Centers for Disease Control and Prevention (CDC) data shows, bringing plenty of stuffy, runny noses along for the ride.
