Back day
The backstay is part of the standing goods on sailing ships and generally refers to a rope that spans a mast or a bar aft (to the rear). A backstay is not always available if other parts of the standing goods adequately fulfill this function. Today a backstay is usually an alternative or in addition to the backstay used in pairs, which runs obliquely aft on both sides from the upper part of the mast , and thus also absorbs lateral forces. Backstage counts as a standing asset, even if they are implemented during maneuvers.
term
On ships without masts , a runner is also sometimes alternatively synonymous as backstay referred, and / or to the shrouds or backstays counted as a generic term. A preventer is also known as "a backstag / pardune that can be thrown off".
In nautical parlance , the terms are also used as follows:
- When trimming the sail , the command Free from the guys means that the yards or the tree just don't touch the guys / backstays
- When there is a backstage breeze, the sails are guided in bulk .
function
You need backstage either if a backstay is not possible due to the shape of the sail (e.g. gaff sails ) or to be able to adjust the mast bend more precisely. Some of the backstays on old work boats are designed so that they can also be used as work troughs .
As a rule, they are designed to be fixed, but can also be lowered in individual cases, e.g. B. when they are attached to a movable bar .
The backstays attack the mast at the height of the forestay fittings. If they are also intended to serve as a work bar, they are equipped with hooks at the lower end, which are hooked into the eyes provided for this purpose .
If the spreaders are swept aft, there is no need to go backstage. Then the upper shrouds take over the task of the backstage. This leads to a significant simplification of handling in yachts.
If possible, the feasible backstays remain enforced. If the sail to the backstays to a shame-filament , located on the other can not be ease out far enough, but that is each windward backstay tensioned to the tension of the sail by Lee counteract the mast and thus prevent the breaking of the mast. In the case of yachts, the forestay can also be tightened. The leeward backstay is then during turning or throat eased , but only after the ship has passed through the wind. If the stay is designed as a work pole, it is unhooked and attached to the intended thimbles or the leeward want . This is necessary because if the stay is loose, the hooks can slip and then pose a danger to the ship and crew.
