Alternative form of dead reckoning [A method of estimating the position of a ship or aircraft by applying estimates of the distance and direction travelled to a previously known position. In respect to ships/boats, it excludes the effect of wind and current on the vessel. Compare with estimated position. Abbreviation: DR]
(nautical) The depth of water needed to float a particular ship; the depth from the waterline to the bottom of a vessel's hull; the depth of water drawn by a vessel.
A verbal command given usually to the bowman of a canoe or raft. It means to place the paddle in the water on the left side parallel to the boat and pull it towards the boat. This is a maneuver to move the front of the boat to the left side.
(navigation) An estimate of the position of a ship or aircraft at a certain time, worked out by adding the estimated effect of the tide and wind to the dead reckoning.
(US, nautical, of speed) Maximum. Historically faster than full speed (the most a vessel can sustain without excessive engine wear or risk of damage), now frequently used interchangeably. Typically used in an emergency or during an attack.
(nautical) Describing the condition in which two sea-going ships travelling in opposite directions pass each other on their starboard sides, making their green navigation lights face each other.

(nautical) Any one of several lines marked upon the outside of a vessel, corresponding with the surface of the water when she is afloat on an even keel. The lowest line indicates the vessel's proper submergence when not loaded, and is called the light water line; the highest, called the load water line, indicates her proper submergence when loaded.
(nautical) A dock that has a constant level of water in which a vessel floats despite the tide; usually achieved by separating the dock from the sea by a lock.
(nautical) The total portion of the surface area of the hull which is immersed in water.
