The structural part of a rudder that transmits the torque created by the tiller or steering gear to the rudder blade. It may consist of a steel tube which passes through bearings in the hull above the rudder, or with a stern-hung rudder, is the structure carrying all or some of the pintles or gudgeons on which the rudder pivots.
In some boats without a coxswain, a rower may be able to control the rudder and steer the boat by changing the direction their foot points. This is called "toeing a boat." And the mechanism is called a "toe." (also: "foot steering") Top-Nut The nut which screws onto the top of the pin holding the Rowlock in place. Tracks (see Slides) Tulip (see ...
Rudder. A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane.
At a stable angle of heel (for a sailboat) and a steady speed, aerodynamic and hydrodynamic forces are in balance. Integrated over the sailing craft, the total aerodynamic force (FT) is located at the centre of effort (CE), which is a function of the design and adjustment of the sails on a sailing craft.
A windvane self-steering with auxiliary rudder and trim tab servo. The main goal of a mechanical self-steering gear is to keep a sailboat on a given course towards the apparent wind and to free the helmsman from the steering job. An advantageous side effect is that the sails are kept in optimal angle towards the apparent wind and deliver ...
In US Navy slang, also called a "flat top" or a "bird farm". air draft air draught maximum vertical extent of any part of the vessel above the water surface. Clearance required for passing under a bridge. [12] aka Structural section of a vessel that joins together the hulls of a multihulled vessel. alee 1. On the lee side of a ship. 2. To leeward.
The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces. If rudder is continuously applied in level flight the aircraft will yaw initially in the direction of the applied rudder – the primary effect of rudder. After a few seconds the aircraft will tend to bank in the direction of yaw.
The top of all sails is called the head, the leading edge is called the luff, the trailing edge is the leech, and the bottom edge is the foot. Head – The head is the upper edge of the sail, and is attached at the throat and peak to a gaff, yard, or sprit. [7] For a triangular sail the head refers to the topmost corner.
