Maneuver (shipping)
A maneuver is understood to be the nautical-technical measures by which a ship is brought into a different position or changed position (is maneuvered ).
Individual maneuvers
As a general rule
- Anchor maneuvers : (drop anchor and weigh anchor) maneuver at anchor
- Docking maneuvers are used to anchor a watercraft to a target.
- Casting maneuvers are carried out in order to free a watercraft from its moored position.
- Driving a duck pond : Full circle driven on the open sea. On the leeward side , the circular movement and the protection of the ship's side create smooth water: the duck pond . From this relatively calm lake with low wave heights, dinghies can be put in safely or people and objects can be picked up more easily. During the Second World War , the catapult aircraft that landed in the water were taken back on board.
- Man overboard maneuver : Maneuver to rescue a person who has gone overboard ("MOB"; abbreviation for: Man over Board ), see also :
- Maneuver of the last moment : If it is essential to avoid a collision, the rules of avoidance may be deviated from (see collision course ).
- Rondo : change of course in inland navigation to travel with the bow in the direction of the current.
Sailing maneuvers
These special maneuvers can only be performed with sailing ships.
- Tack : change of course in which the bow turns due to the wind until the wind comes in from the other side. The command to turn is Ree!
- Jibe : change of course in which the stern turns due to the wind until the wind comes in from the other side.
- Backbream , backing : braking of sailing ships by setting the sails against the wind.
- Aufschießer : Put the sailing ship in the wind to slow it down
In an all-hands maneuver / all-man maneuver , all crew members ( "all hands" ) must participate in a dangerous situation because of the difficulty or the necessary speed. Example: Mountains of sails due to a suddenly approaching storm.
maneuverability
Maneuverability is the general ability of the ship to perform a desired maneuver using its own or third-party steering aids. A distinction is made between certain characteristics and skills:
- Start-up / (stop) ability describes how quickly a ship can pick up speed or come to a standstill using its main propulsion system.
- Swiveling capacity describes how quickly a ship begins to react to the use of steering aids by changing its position.
- Turnability describes how quickly (in terms of time and, above all , on which route) a ship can absolutely change its position using steering aids .
- Support capacity is the ability to bring an initiated rotary movement to a standstill with or without the use of control aids.
