Lee-board. A board fitted to the lee side of flat-bottomed boats, to prevent their drifting to leeward.
Lee-gage. (See Gage.)
Leeway. What a vessel loses by drifting to leeward. When sailing close-hauled with all sail set, a vessel should make no leeway. If the topgallant sails are furled, it is customary to allow one point; under close-reefed topsails, two points; when under one close-reefed sail, four or five points.
Leech, or Leach. The border or edge of a sail, at the sides.
Leefange. An iron bar, upon which the sheets of fore-and-aft sails traverse. Also, a rope rove through the cringle of a sail which has a bonnet to it, for hauling in, so as to lace on the bonnet. Not much used.
Leeward. (Pronounced lu-ard.) The lee side. In a direction opposite to that from which the wind blows, which is called windward. The opposite of lee is weather, and of leeward is windward; the two first being adjectives.
Lie-to, is to stop the progress of a vessel at sea, either by counter-bracing the yards, or by reducing sail so that she will make little or no headway, but will merely come to and fall off by the counteraction of the sails and helm.
Life-lines. Ropes carried along yards, booms, &c., or at any part of the vessel, for men to hold on by.
Lift. A rope or tackle, going from the yard-arms to the mast-head, to support and move the yard. Also, a term applied to the sails when the wind strikes them on the leeches and raises them slightly.
Light. To move or lift anything along; as, to "Light out to windward!" that is, haul the sail over to windward. The light sails are all above the topsails, also the studdingsails and flying jib.
