Tacking or coming about is a sailing maneuver by which a sailing craft (sailing vessel, ice boat, or land yacht), whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. [1]
If the destination is upwind but the sailboat goes fastest heading away from this direction, this poses a significant problem: how to choose tack headings with the best tradeoff between maximimizing speed and minimizing distance. The ability to define an efficient tacking route is an important issue in sailboat racing, and for recreational sailing.
Alternatively, the vessel can simply be turned normally to tack through the wind, without freeing the jibsheet. [5] [1] [11] The mainsail should self-tack onto the other side, but the jib is held aback. Finally the rudder is put the other way, as if trying to tack back again. Without the drive of the jib, she cannot do this and will stop hove to.
A tack is the windward side of a sailing craft (side from which the wind is coming while under way)—the starboard or port tack. Generally, a craft is on a starboard tack if the wind is coming over the starboard (right) side with sails on port (left) side. Similarly, a craft is on a port tack if the wind is coming over the port (left).
The quick turn is essentially a figure eight. On a sailboat it consists of the following steps: Change course to a beam reach and hold for 15 seconds; Head into the wind and tack, leave the jib fluttering; Veer off until the boat is at a broad reach; Turn upwind until the vessel is pointing at the victim; at this point the vessel should be on a ...
The ship is close-hauled and the sail is now controlled by the tack rather than the sheet. The tack of a square-rigged sail is a line attached to its lower corner. [1] This is in contrast to the more common fore-and-aft sail, whose tack is a part of the sail itself, the corner which is (possibly semi-permanently) secured to the vessel.
Dipping lug: This is a boom-less sail whose yard is lowered or "dipped" when tacking to bring the sail around to the leeward side of the mast. In some cases this can be done by partially lowering the yard - there are a number of variations in this procedure. The tack fastens to a point some distance forward of the mast. For a foresail this may ...
Sailing performance with a standing lug relies on the right amount of luff tension. An essential component of this rig is the tack tackle, a purchase with which luff tension is adjusted for various points of sail. [4]: 34 The balanced (or balance) lug has a boom that projects in front of the mast roughly the same distance as the yard.
