2. Ship's wheel - Wikipedia

   en.wikipedia.org/wiki/Ship's_wheel

   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 ...

3. Ship stability - Wikipedia

   en.wikipedia.org/wiki/Ship_stability

   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.

4. Metacentric height - Wikipedia

   en.wikipedia.org/wiki/Metacentric_height

   In a boat, the equivalent of the spring stiffness is the distance called "GM" or "metacentric height", being the distance between two points: "G" the centre of gravity of the boat and "M", which is a point called the metacentre. Metacentre is determined by the ratio between the inertia resistance of the boat and the volume of the boat. (The ...

5. Self-steering gear - Wikipedia

   en.wikipedia.org/wiki/Self-steering_gear

   The increased low wind capabilities of optimized, modern devices enable downwind steering down to 1.3 m/s apparent wind and 1.5 kn of boat speed [8] [9] – properties that make an electronic steering device nearly redundant and enable crossing the doldrums under wind vane self-steering. An increasing number of long distance regatta sailors are ...

6. Helmsman - Wikipedia

   en.wikipedia.org/wiki/Helmsman

   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.

7. Tank steering systems - Wikipedia

   en.wikipedia.org/wiki/Tank_steering_systems

   Turning the steering wheel displaced the bogies to the left or right inducing a modest turn. Further turning of the wheel engaged braking on one side or the other. The Light Tank Mk VII Tetrarch used a similar system but the front wheels and two middle wheels on either side pivoted to induce the warp. [7]
