Jibe

from Wikipedia, the free encyclopedia
Jibe

Jibe describes a maneuver in sailing in which a vehicle goes with its stern through the wind and the sails are then guided on the other side of the ship.

In contrast to writing , a jibe is always associated with a change in course . The term derives from the jibes from: lines, the neck of a Rahsegels , are posted to the sail on a close-hauled course to bring forward.

In strong winds, jibing with a scraper requires great attention. In the event of an unclean technical design, a patent neck occurs in which the large tree turns over to the other side in an uncontrolled manner. A jibe is less of a challenge for square sailers .

The maneuver in which the vehicle goes with its bow through the wind is called a turn . Instead of a jibe, in rough weather and inexperienced crew, a Q- turn or a cow turn can be used.

The jibes on dinghies and yachts

The jibe is initiated on a downwind or downwind course . An existing traveler is first placed in the middle. You let the vessel drop carefully until the foresail collapses and the bowman shouts “Jib falls!”. On larger yachts, the main sheet is quickly brought in to prevent the main boom from going over uncontrollably. As soon as the stern has gone through the wind, support rudders are put in place (steered against the direction of rotation) to absorb the turning movement of the boat. Mains and headsail are now on the other side of the ship; their pods are eased . Finally, the skipper announces the new course and the sails are adjusted accordingly.

Sequence of sailing commands when jibing

(See commands in shipping )

  1. "Ready to go?"
  2. (Answer) "It is clear!"
  3. “New course: Raumer Wind! Fier on the pods! "
  4. (Bowman :) "Jib falls!"
  5. "Close up the mainsheet!"
  6. "Round aft!"
  7. "(Haul) over the jib"
  8. "Fier on the mainsheet!"
  9. "New course: ..."

Variants of the neck

The regatta neck and the danger neck differ from the usual form of the jibe, which is sometimes called the block jibe .

Regatta neck

A faster way of jibing, and therefore developed for regattas , is the regatta neck, in which the main sheet does not have to be hauled up or lowered. The helmsman grabs the boom or main sheet on a downwind course and shifts the boom to the other side of the ship. This type of jibing requires more practice and is only manageable on smaller boats with light trees and in moderate winds.

Danger neck

A hazard neck is similar to a regatta neck. It is assumed, however, that the starting course is a close-hauled course and that a hazard requires a sudden leeward dodging.

The oars are laid hard and dropped, the pods are lowered. As soon as a downwind course is reached, the boom is shifted to the other side of the ship, as with the regatta neck. If necessary, support rudders are put down and luffed. The pods are picked up and the new course steered.

Patent neck

A patent jibe is an accidental jibe that neither the ship nor the crew are prepared for. With the patent jib, the mainsail and the boom suddenly move from one side of the ship to the other at high speed. This happens when a sailing vehicle drives space sheets or in front of the wind and the wind suddenly grabs the sail from the other side.

Most of the time, a patent jibe is preceded by a driving or steering error. Other reasons could be changes in wind direction or sudden changes in current that turn the vehicle. When sailing in shallow waters, the sword of sailing boats can get caught in the ground and act like a swivel joint. Another cause is high waves with the result of a strongly yawing sailing vehicle .

The sudden overflow of the tree poses a serious risk to the ship and crew at the patent jibe. If the mainsheet was previously raised wide, the boom on the opposite side can rush into a shroud or backstay and break the same, which can subsequently cause further damage to the rigging and even break the mast. If crew members are in the path of the tree or the main sheet, there is a risk of serious injuries and going overboard. If crew members went unconscious overboard as a result of the blow (to the head), there is a risk of death (see also man overboard maneuvers ). With dinghies there is an additional risk of capsizing due to the sudden shift in wind pressure .

One precaution to prevent a patent jibe is the set bull stand , which secures the tree against going over.

In order to make a patent jibe less likely, a course higher upwind than the one that corresponds to the desired direction of travel can be chosen, especially in heavy seas. The crosses from the wind also has the advantage that an aim which is in Lee is reached faster in general, despite the longer path, due to the higher boat speed.
