Windward and leeward

Luv is a term used by sailors language and describes the wind -facing side of the boat, for example, in shipping (see also: sailing).

Lee referred accordingly to the Luv opposite, ie facing away from the windward side. For sail boats in driving Lee is the boat side on which the sails ( mainsail ) is.

How many terms of the sailor language comes from the Dutch Luv. With loefzijde the Rudder is meant, because on this side a kind of auxiliary rudder had to ensure that the ship did not turn into the wind. Lee also comes from the Netherlands ( lijzijde ), meaning " warm body".

Both terms were settled for the 17th century and in other areas through, for example, meteorology or geography. Here, Luv the windward side of a topographic obstacle ( weather vagina) with a rising wind and thus often associated precipitation ( orographic orographic rainfall ). Lee accordingly designated the downwind side of the obstacle where the wind drops and can become a hair dryer, and are less precipitation.

Luv or Leestellung

For the tactical command of sailing warships, the concept of Luvstellung or Leestellung was of particular importance, ie the relative position of a ship or fleet from / to each opponent:

• If ship B is located on the windward side of ship A, so it has the " Luvstellung ". Ship B can maneuver at will and forcing the fight, because Ship A would tick against the wind in order to reduce the distance between the ships under its own power.
• Conversely, there is A ship on the lee side of B, so it has the Leestellung. From this out A can normally enforce no action, but better to remove them from the other ship.

A fleet tried usually thus always to gain Luvstellung against the enemy fleet to maneuver itself more freely. An inferior fleet, which tried to avoid the fight, had to mostly prevent exactly this.

In addition, the windward or Leestellung plays a role in the way rules between sailing vehicles.

" Make Lee" in seafaring

In the maritime field, the fact that the sea in the lee of the fuselage is noticeably quieter than the windward side, used, for example, if a pilot offset or a boat must be suspended or taken on board. The maneuver in which the ship is rotated to wind and sea that calms the sea as possible, is called " make Lee". In a life raft that is left ( the sinking of a ship that is ) into the water in an emergency, it automatically opens a so-called floating anchor, which prevents the boat drifts away towards Lee and the boat is kept in a seaway.

Similarly, ships, seaplanes on board, which must land in the water ( seaplane carriers ), facilitate their landing by only go against the wind and then control a 90 ° curve. This will allow the seaplane to land against the wind and use the quiet crescent wake of the ship.

Windward and leeward in aviation

In aviation, the terms windward and leeward for the wind facing or Rear facing an obstacle or aircraft to be used.

Others

In the animated film Finding Nemo in 2003 occurs in a Supporting Role of the Four -banded Prussia fish ( Dascyllus melanurus ) Lee & Luv. The relationship between the ambiguous nature of the figure and the ambiguity of the concept of windward and leeward is similarly clear as in the original English name Deb & Flo, the on Ebb and Flow, so ebb and flow, alludes.
