labor - Heavy rolling or pitching while underway.

lacing - A lineline used to attach a sail to a spar.

laid up - A boat in a dry dock.

land breeze - A wind moving from the land to the water due to temperature changes in the evening.

landlocked - Surrounded by land.

landmark - A distinctive reference point that can be used for navigation.

lanyard - A line attached to a tool.

lash - To tie something with a line.

lateral resistance - The ability of a boat to keep from being moved sideways by the wind. Keels, daggerboards, centerboards, and leeboards are all used to improve a boat's lateral resistance.

launch - 1 - To put a boat in the water. 2 - A small boat used to ferry people to and from a larger vessel.

lay - The position of an item.

lazarette - A small aft storage space for spare parts and other items.

lazy guy - A line attached to the boom to prevent it from accidentally jibbing.

	Lazyjack - Lines attached to both sides of a boom, usually the mainsail. They act as guides and catchers for the sails as they are lowered.
	lazy sheet - A line led to a sail, but is not currently in use. The line currently in use is known as the working sheet. Usually the working and lazy sheets change when the boat is tacked.

lead line - A line with a weight on the end used to measure depth. The lead is dropped into the water and marks on the line are read to determine the current water depth. The lead usually has a cavity to return a sample of the bottom type mud, sand, etc. -

leading marks - Unlit navigational aids for use during the day. Like leading lights, they mark a bearing to a channel when they are lined up one above the other.

league - 3 nautical miles.

leech line - A line used to tighten the leech of a sail, helping to create proper sail shape.

leech - The aft edge of a fore and aft sailsail.

leecloths - Cloths raised along the side of a berth to keep the occupant from falling out.

leeward - The direction away from the wind. Opposite of windward.

leeway - The sideways movement of a boat away from the wind, usually unwanted. Keels and other devices help prevent a boat from having excessive leeway.

licensed pilot - A pilot with a license stating that they are qualified to guide vessels in a particular area.

lie - 1 - Where an object is. 2 - To put an object in place.

life boat - A small boat used for emergencies such as when the parent boat is sinking.

light list - A list of lights arranged in geographical order.

light - A lit navigational aid such as a lighthouse that can be used at night or in poor visibility.

lightship - A light placed on a ship. The ship remained in a fixed position. Most lightships have been replaced by lit buoys or other structures.

linestoppers - A device used to keep a line from slipping, such as a jamcleat.

liquid petroleum gas - LPG or propane for short. Propane is a common fuel used for cooking and heating. CNG natural gas - is considered safer because propane is heavy than air and will sink into the bilge if it leaks, creating the potential for an explosion. Propane is more easily available throughout the world than CNG however, so it is used for most boats outside of North America.

list - A leaning to one side when not underway. Usually the result of an improperly loaded boat. Heeling is different from a list because it is caused by the forces of wind acting upon a sailboat that is underway. When a boat changes tacks, the direction of the heel will change sides, whereas a list is a continual leaning to the same side under any condition.

log - A device used to measure the distance traveled through the water. The distance read from a log can be affected by currents, leeway and other factors, so those distances are sometimes corrected to a distance made good. Logs can be electronic devices or paddle wheels mounted through the hull of the boat or trailed behind it on a line.

longitude - Imaginary lines drawn through the north and south poles on the globe used to measure distance east and west. Greenwich England is designated as 0� with other distances being measured in degrees east and west of Greenwich. For example the center of California, USA is approximatly 120� west and the center of Australia is around 135� east. Also see latitudelatitude.

lookout - A person designated to watch for other vessels and hazards.

LORAN - An electronic instrument using radio waves from various stations to find one's position. The LORAN system is being replaced by the GPS system and will be obsolete in a few years. Many LORAN stations have already stopped providing service.

LPG - Liquid petroleum gas or propane. Propane is a common fuel used for cooking and heating. CNG natural gas - is considered safer because propane is heavy than air and will sink into the bilge if it leaks, creating the potential for an explosion. Propane is more easily available throughout the world than CNG however, so it is used for most boats outside of North America.

lubber line - A mark on a compass used to read the heading of a boat.

luff - The edge of a sailsail toward the bowbow of a boat.
