Casting maneuvers
A casting off maneuver is a maneuver in which a watercraft leaves its berth . The term is used both in ports and during locks and describes the maneuver that precedes departure.
(High) ocean-going vessels

As with the mooring maneuver, the casting off from the pier on ocean-going vessels is carried out by tugs , ship fasteners and harbor pilots . Only after exiting the port does the captain take command of the ship again himself.
Barges
Inland vessels set off from the dock themselves, perhaps with the help of ship fasteners that are on land. The bow thruster , with which the ship can be moved sideways, also plays an important role.
Pleasure craft
Store under engine
Sports boats can be cast off from a buoy , a jetty, a jetty box or a package (several boats are next to each other if there is not enough space on the jetty). Depending on the situation, a different approach is indicated. Lowering from a buoy or in the lock under the engine does not require any special maneuvers. Only the mooring lines have to be loosened.
When the boat is on the jetty, i.e. parallel to the jetty, it is lined with lines at the front (bow) and aft (stern). Discarding maneuvers must now be planned, discussed, prepared and carried out depending on the situation. The wind direction, the current and the torque of the propeller (motor) must be taken into account. If the wind is onshore , the stern line is first loosened and the stern turned away from the jetty. Then the bow line is released and the boat is straightened so that it can move forward. In offshore wind it is the other way round: First the bow line is loosened, the bow is twisted off the jetty and then the stern line is loosened.
When leaving a dock box, the two bow lines and one stern line are released. The boat reverses and is still secured with a stern line to the pole around which the boat turns in the desired direction of travel. Then this line is also released and the boat can go.
When unloading from the package, the bow and stern lines are loosened on your own boat, the bow lines or the stern lines are loosened depending on the situation on the outer neighboring boats. A breast line from the outer neighbor is looped around the back of your own boat in order to later connect the two new neighbors. The further procedure: throw off the jumping and breast lines to the outer and inner boat; drive slowly ahead; the remaining boats tie up the fore or stern lines as well as the jumping and chest lines.
The casting off maneuvers are often carried out by evaporation into a mooring line , especially when there is little space available and unfavorable wind and current conditions. The fenders (protective cushions on the outer wall of the boat) must also be observed during all of these maneuvers.
Cast off under sails
When casting off under sails, different maneuvers are useful depending on the wind direction. The easiest way to get rid of the buoy is here too. Different sails are set depending on the situation and wind direction. The most difficult maneuver is casting off in onshore winds. The sails are only pitched and only set during the maneuver. Here, too, it may be necessary to turn the sailboat with the help of mooring lines.
