A mainsheet is a line connected to the boom which allows a sailor to control the speed of a boat. The jib sheet attaches to the clew of the jib, and controls it. The jib has a sheet on each side, only one of which (the leeward one) will be in use at one time. The spinnaker sheet attaches to the clew(s) of the spinnaker, if carried. A ...
Stays are ropes, wires, or rods on sailing vessels that run fore-and-aft along the centerline from the masts to the hull, deck, bowsprit, or to other masts which serve to stabilize the masts. [ 1 ] A stay is part of the standing rigging and is used to hold a mast upright.
If the sail is supported with a boom, gaff or sprit the change may be violent—unless the sheets are tight—as the sail is blown to the other side. For a jib, the old leeward sheet is loosened as the stern turns through the wind and the old windward sheet is tightened as the new leeward sheet to allow the sail to draw wind.
This is called the sheet and serves a slightly different function. When the boat jibes, the spinnaker pole will be moved from one side of the boat to the other, causing the sheet to become the guy and vice versa. A foreguy may also be used to control the height of the spinnaker pole. It is attached either to the end of the pole or to a bridle ...
The triangular sail is maneuvered by a sheet that slides freely on a steel rod installed between two stands fully aft of the boat. [18] The fixing point of the maneuver lines is usually placed between two stands (from the 3rd to the 5th "stand") in a battery of mechanisms called "piano". In addition to the ropes that act as stays,.
The beam of a ship is its width at its widest point. The maximum beam (B MAX ) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H ) only includes permanently fixed parts of the hull , and beam at waterline (B WL ) is the maximum width where the hull intersects the surface of the water.

Equipped with a spinnaker, trapeze and a large sail-area-to-weight ratio, it is designed to plane easily, and good teamwork is necessary to sail it well. The name comes from the boat's length of 470 centimetres (4.7 m; 15 ft 5 in). The 470 is a World Sailing International Class and has been an Olympic class since the 1976 games. [1]
