RAPTURE OF THE DEEP - Also known as nautical narcosis. Its symptoms include an inability to use common words, such as up, down, left, right, front, and back, and their substitution with a variety of gibberish which the sufferer believes to make sense; a love of small, dark, wet places; an obsessive desire to be surrounded by possessions of a nautical nature, such as lamps made from running lights and tiny ship's wheels; and a conviction that objects are moving when they are in fact standing still. This condition is incurable.
RANGE – 1.Two aids to navigation which, when seen to be in line, establish a line of position (transit). 2. The difference in depth between high and low tides
REACH - Sailing with a beam wind.
READY ABOUT – An expression used to indicate that the boat is about to tack
REEFING -The operation of reducing a sail by taking in one or more of the reefs
REEF BANDS - Pieces of canvass, about six inches wide, sewed on the fore part of sails, where the points are fixed for reefing the sail.
REEF KNOT – A joining knot
REEF POINTS - Short line through the reef band to secure the foot of the sail
REEVE - Leading a line through a block or other object.
RELATIVE WIND – The direction and velocity of the wind as observed from a moving vessel
RHUMB LINE - A line that passes through all meridians at the same angle. When drawn on a Mercator chart, the rhumb line is a straight line. However the Mercator chart is a distortion of a round globe on a flat surface, so the rhumb line will be a longer course than a great circle route.
RIGGING - There is, generally, two types of rigging, even on a modern steam ship, standing and running rigging. Standing rigging is that rigging which is fixed in place, such as halyard and stays which support a mast, and are not intended to be easily adjusted or changed. Running rigging is that which is easily adjustable, such as the main sheet, used to adjust the main sail, or the rigging on a ships crane which raises and lowers cargo.
RIGHT – To return to a normal position, as a vessel righting after heeling

RUDDER - A large, heavy, vertically mounted, hydrodynamically contoured steel plate with which, through the action of a tiller or wheel, it is possible, during brief intervals, to point a sailing vessel in a direction which, due to a combination of effects caused by tide, current, the force and direction of the wind, the size and angle of the waves, and the shape of the hull, it does not wish to go.
RUDDER POST - The post that the rudder is attached to. The wheel or tiller is connected to the rudder post.
RUMMAGE - Originally meant "to stow cargo". Now, means "to search a ship carefully and thoroughly".
