sea-language, is used as an adjective, and applied by mariners to every thing lying to windward of a particular situation: thus, a ship is said to have the weather-gage of another, when she is farther to windward. Thus also, when a ship under sail prefers either of her sides to the wind, it is then called the weather-side or weather-board; and all the rigging and furniture situated thereon are distinguished by the same epithet, as the weather-sprouts, the weather-lifts, the weather-braces, &c.
To WEATHER, in sea-language, is to fail to windward of some ship, bank, or head-land.
WEATHER-COCK, a moveable vane, in form of a cock, or other shape, placed on high, to be turned round according to the direction of the wind, and point out the quarter from whence it blows.
