Topmast Hoops - Hoops were formerly used for jib-headed topsails, the same as they used to be for the original "gaff topsails." The hoops when not in use rest on the masthead. In hoisting the topsail the lacing is passed through an eyelet hole in the luff of the sail and through a hoop, and so on. When the sail is hoisted chock-a-block the lacing is hauled taut; in lowering the lacing is slackened. Hoops facilitate the hoisting and lowering of the sail, and admit of its being lowered and hoisted without a man going aloft
Topping lift - A line or wire rope used to support the yards or booms when a boat is anchored or moored.

A rope used to keep a gaff from sagging to leeward. On a schooner's foresail a block is lashed to the mainmast head, through which the vang is rove and made fast to the fore gaff end; the fall of the rope leads to the deck. In square-rigged ships vangs are generally used on the spanker gaff. Sprit sail barges also use vangs.
Variation of the Compass - The departure the compass needle shows from true North at certain parts of the globe. The difference between magnetic and true North usually expressed in degrees on charts. The change is annual and either decreases or increases.

Way Enough - In rowing, an order given by the person steering a boat when being rowed alongside a vessel or causeway to direct the oarsmen to cease rowing with the stroke about to be completed, and lay in their oars. Way enough! is strictly and merely an order to cease rowing and should be followed by the order "Oars!" if the men are to be directed to lay in their oars. In practice, however, the orders "Way enough!" and "Oars !" have an identical effect upon a smart yacht's crew when bringing a boat alongside, i.e., simply to cause the crew to cease rowing, throw up their oars, and lay them in the boat.
Ways - Balks of timber arranged in a kind of chute to haul vessels upon or to launch them off.
Wear - To bring the wind on the other side of a vessel by putting the helm up so that the vessel's head goes round away from the wind instead of towards the wind as in tacking. Used on square rigged vessels instead of gybe.
Weather - The windward or "breezy" side of an object. The side on which the "weather" is felt; not to leeward. To weather is to pass on the windward side of an object. In cross tacking the vessel "weathers" another that crosses ahead of her. To weather on another vessel is to gain on her in a windward direction by holding a better wind than she does -- to eat her out of the wind.
Weather Board - On the weather side of a vessel. Sometimes in working to windward by a long board and a short one the short one is called "weather board."
Weather Boards - Pieces of boards fitted over open ports to direct water or rain off.
Weather Cloth - The cloth in a sail next the luff. The "weather" leach of a sail is the luff.

Weather Gauge - The condition of a vessel that is to windward of another one. In slang, to possess an advantage.
Weather Helm - The helm or tiller hauled to windward when a vessel owing to too much after sail has an inclination to fly up in the wind. If the centre of effort of the sails is much abaft the centre of lateral resistance, a vessel will require weather helm to keep her out of the wind. The tendency to fly up in the wind can he remedied by reducing the after sail, or setting more head sail, or by easing the main sheet. However, all vessels should carry a little weather helm. (The contrary to "Lee Helm," which see.) It has been frequently argued that the effect of the water pressure on the rudder when the helm is to windward (that is the rudder to leeward), is to press the vessel bodily to wind. ward, and no doubt there is some truth in this, although the influence of the rudder in this respect could be only small.
Weathering - A relative term used in sailing to define the action of one vessel which is eating to windward of another, thus, if a vessel is said to he weathering on another she is eating her out of the wind, or closing up to her from the leeward, or departing from her in a windward direction. Weathering an object is passing on its windward side.
Weatherly, Weatherliness -
The quality of hanging to windward well or holding a good wind. This term is often improperly used to denote good behaviour in a sea way or in bad weather.
Weather Lurch - A weather roll or a roll to windward. In running with the main boom well off, the boom should be always secured with a guy, or it may fall to the opposite side during a weather roll, and cause some damage.
