Ropework is commonly defined as the set of processes of making and repairing ropes; some, however, also include any other work that can be done with ropes, such as tying knots and splicing. Actually, only a few of the "ropes" on a boat are called ropes, most are called lines. Ropes or wires that hold up masts are collectively known as standing rigging and are called shrouds or stays (the stay connecting the top of the mast to the bow is called the forestay or headstay). Ropes or wires that control the sails are known collectively as running rigging or lines. Those that raise sails are called halyards while those that strike them are called downhauls. Ropes that adjust (trim) the sails are called sheets. These are often referred to using the name of the sail they control (eg. "main sheet", or "jib sheet"). Ropes used to tie the boat up when alongside are called docklines. |

Beating an upwind course A basic rule of sailing is that it is not possible to sail directly into the direction the wind is coming from. Generally a cruising boat can sail 45 degrees off the wind, a racing boat may aproach 35 degrees. However since it is often necessary to move towards the wind direction, it is necessary to 'beat' upwind. Beating is simply a series of 'tacks' where the boat sails as close to the wind on each tack as possible, and then switches sides and repeats the process. By this method, it is possible to travel directly into the wind. The heavier the wind the harder the beat, and since you are sailing into oncoming waves at an angle, boat movement can be heavy. This movement can feel like the boat is beating its hull into the waves, hence the name. Since the boat is sailing over oncoming waves, a beat will feel faster than its actually moving. During a beat, it is important to watch your heading, since the wind will tend to push an unbalanced boat into or away from the wind, depending on the balance problem. If you find yourself having to overcorrect at the helm for sail pressure into the wind, then you are in a condition called weatherhelm, and you are actually slowing the boat with your rudder. To correct this, reduce sail. |

A sail is a surface intended to generate thrust by being placed in a wind; basically it is a vertically oriented wing. Depending on the incident angle of the wind on the surface of the sail, one side of the sail will have a higher air pressure than the other one according to Bernoulli's principle. The difference in pressure will generate lift, causing the sail to be pulled towards the side of lower pressure. On a sailing boat, a keel or centreboard is used to convert this lateral force into forward movement of the boat with some sideways leaning, or 'heel'. Use of sails Sails are primarily used at sea, on sailing ships as a propulsion system. For purposes of commerce, sails have been largely superseded by other forms of propulsion, such as the internal combustion engine. For recreation, however, sailing vessels remain popular. The most familiar type of sailboat, a small pleasure yacht, usually has a sail-plan called a sloop. This has two fore-and-aft sails: the mainsail and the jib. The mainsail extends aftward and is secured the whole length of its edges to the mast and to a boom also hung from the mast. The sails of tall ships are attached to wooden timbers or "spars". |
