Halyard

As a case ( neuter, plural: the traps ) is called on sailing ships a piece of rope, the pull up ( down) and lowering (Bergen ) or reefing is used by sailing. Cases belong to the date Well a sailing ship.

Types and names

For hoisting ( pull up) of a triangular sail ( sail high ) is only a single case used that at the highest point of the sail, the sail head attached ( struck) is. When Gaffelsegel serve two traps hoisting the gaff: the throat halliard and Piek case that attacks tightly about the middle of the gaff. Otherwise, the traps are designated according to the sails that are raised with them - for example, main halyard ( for the mainsail ) or spinnaker halyard.

Materials

Generally, the material should meet certain requirements for traps:

• It should be as resistant to salt water, UV radiation and abrasion
• It should stretch as little as possible, So under load possible, not lengths to avoid the sail in the course of time " sag ".
• The line should be as easy to grip and easy to handle ( " Lehnig ").

Originally, only natural fibers such as hemp or sisal were available, but the stretched out strong and were partly strongly prone to rot. Therefore, they are now replaced itself on traditional ships usually by more modern materials. A next step of development were traps made ​​of steel cables that stretched already considerably less and - especially when using stainless steels - were significantly more durable. However, these ropes can no longer be pulled by hand, so special Drahtseilwinschen must be used. In addition, individual Kardeele (the " strands " ) break the ropes and protrude from the rope, which is a risk of injury by so-called " meat hook " means. On some traditional ships and yachts wire traps, however, are still in use. Today traps are usually made of synthetic fibers reck poor. At low requirements linen made ​​of polyester used, because of its relatively poor stretching properties using racers and demanding trip sailor instead linen made ​​of Dyneema.

For traps nowadays only braided rope is used as laid rope by its construction has too much stretching.

Case as running rigging

On modern sailing yachts traps can be laid inside the mast. They run on a ball-bearing role often be stretched down over a winch and fixed by a halyard stoppers or cleat for (see documents on the cleat ). At the other end of the sail is attached to a shackle. The shackle is either spliced ​​, alternatively tied with a bowline or Gordingstek.

The halyard is led twice for serious sailing as a tackle. To support often serves an electrically or hydraulically operated winch.

When the sail is hoisted, the case length of the mast height (or twice as long ) lies on the deck. Thus, it is always ready for use and does not form Wuling, it will be shot.

Trim

The case serves the sail trim to control the luff. This is then properly trimmed when the sail is wrinkle-free. Transverse folds to the luff indicate an insufficient downhaul longitudinal folds too high a voltage. This voltage is always dependent on the wind pressure which is effective at a particular time in the sail. Accordingly, the luff must be continuously adapted to the wind strength and to the feathered position, so even with every change of direction. To make sure that the sail must not always be taken against gravity with the case up, it is drawn at the well-equipped ships with a pulley ( Cunningham Straightener ) down.
