Low water mark – The lowest point along a coastline that any given tide recedes to.
Low pressure area – In an area of low pressure the air has a tendency to rise. This general upward motion means that there is less pressure from the air pushing down on the earth, in other words there is low pressure. As air rises, it cools and if there is enough water vapour it may condense to form clouds and rain.
Littoral zone – The region of land bordering the sea which extends below the low water mark and above the shoreline.
Line capacity – The length of line which can fit on to the spool of a reel. Manufacturers usually list this by breaking strain and / or line diameter.
Lever drag – an multiplier reel with an adjustible drag which is operated by a lever as opposed to a star drag.
Level wind – The part of a multiplier reel which oscillates along the front of spool laying the line evenly.
