Relative Wind - The speed and relative direction to from which the wind appears to blow with reference to a moving point (also called Apparent Wind) ...

relative bearing - Expressed in degrees, a direction in relation to the fore-and-aft line of a ship.

Relative bearing - A direction in relation to the fore-and-aft line of a vessel.
S
Scupper - A drain hole that allows water falling on deck to flow overboard.

Finally, the relative bearings of two vessels affect the degree of risk. Two vessels meeting on near-reciprocal courses would close relatively rapidly, because their closing speed would be the sum of the two speeds.

Relative bearing is the direction relating to the ship with the bow 0° and the stern 180°.

Abaft the beam - A relative bearing of greater than 90 degrees from the bow. e.g. "two points abaft the port beam."
Abandon Ship - An imperative to leave the vessel immediately, usually in the face of some imminent danger.

When a boat is approaching from an angle up ahead, (c) you can tell that you are on a collision course if the Relative Bearing to that vessel remains constant (d).

A compass bearing is in magnetic degrees as shown on a compass. A relative bearing is the inscribed angle between the objects. A crewmember takes a bearing or cuts a bearing.

Closest Point of Approach (CPA) - The nearest another vessel will come to yours when both are under way, usually expressed in distance and relative bearing.*
Clothing - Various pieces of rigging which hold a bowsprit in position.
