A […] Sheet In sailing, a sheet is a line rope, cable or chain used to control the movable corner s clews of a sail. Reference: Wikipedia Shroud On a sailboat, the shrouds are pieces of standing rigging which hold the mast up from side to side. There is frequently more than one shroud on each side of the boat. Usually a shroud will connect at the top of the mast, and additional shrouds might connect partway down the mast, depending on the […] Skeg A skeg, skegg or skag is a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line.
In more recent years, the name has been used for a fin […] Spinnaker A spinnaker is a sail designed specifically for sailing off the wind from a reaching course to a downwind, i. The spinnaker fills with wind and balloons out in front of the boat when it is deployed, called flying. It is constructed of lightweight fabric, usually nylon, and is […] Spinnaker Pole A spinnaker pole is a spar used in sailboats both dinghys and yachts to help support and control a variety of headsails, particularly the spinnaker.
Once they had made their sailboat and started to use it they realized it could also be used during war. The sailboat was made with bundles of papyrus and wood. The sails were made up of linen and had a square shaped sail. They were made lightweight so they were easy to move from land to sea. The sidewalls were raised to protect oarsmen from attack.
The platforms of the boat were raised so the archers could shoot their bows and arrows at the enemies with more accurate aim. In the later years of the sailboat rams were added to the front to smash through enemy ships during battle.

The primary purpose of the wings underneath the ship is to improve handling and stability. In addition, they slightly lift the craft above the surface of the water. As a result, the total wetted surface area remains constant and may even decrease.
Thus, speed remains constant and may improve as the craft picks up velocity. The mast of the vessel refers to a vertical shaft extending out of the deck which supports the sails and rigging. Older models of sailboats and ancient ships had masts constructed out of wood, while modern speed-oriented versions use galvanized steel or aluminium.
Aluminium has the benefit of being extremely light while still retaining its strength, which is important during harsh weather conditions.
The various mast-based classification includes — sloop, fractional-rig sloop, cutter, ketch, schooner and catboat. The sloop is the most common mast type, where a single mast supports two sails called the headsail or foresail and the mainsail.
The headsail also goes by different names depending on the purpose and configuration of the sails. In a fractional rig sloop , the forestay cable that is used to hoist the headsail is actually placed below the top of the mast. This configuration is particularly useful when it comes to performance, as the tip of the mast can be hauled towards the aft using stiff cables, and the sails can be collapsed. This is useful on days when wind power can be used to propel the sailboat, without the sails had to be fully extended.
Another useful feature of being able to trim or flatten the sails is that during particularly strong squalls of wind, the sails will not be punctured or ruptured due to the high wind pressure.
The next type of mast configuration is the cutter. This involves a single mast supporting three sails- one mainsail, and two headsails known as the staysail hauled by the inner stay cable, and the jib hauled by the headstay cable. The mast is located more towards the aft compared to the sloop, to allow for an easily manoeuvrable configuration. In addition, a wide range of sail arrangements makes it favourable for cruise operators and for competition purposes. The ketc h has a two-mast configuration, with the aft mast known as the mizzen mast.
The mizzen mast is located fore of the rudder post, and aft of the main mast. The mizzen sail rests on the mizzen mast. In general, the mizzen mast is slightly shorter than the main mast. The schooner is another configuration similar to the ketch, but where the aft mast is taller than the foremast. Schooners can have multiple masts and are not restricted to commercial small and medium sailboats. The images of ancient ships that were used for trade and military purposes were often schooners having between four to six masts with an average of over ten sails each.
In addition, the sails of the schooner tend to lie along the length of the vessel, rather than along the beam. This is to prevent sail rupture during violent storms or during heavy winds. The catboat is one of the simplest configurations where only a single sail and mast arrangement are used. The mast can be located either aft or fore of midships, with varying advantages to each configuration. The ease of design and construction makes it a favourable sailboat for beginners and trainees.
However, the disadvantage behind the catboat is that the sail cannot be used to move against the direction of the wind, unlike other sail variations. Apart from recreation purpose, sailboats are one of the most common types of vessels used in recreational purposes and for competitions.
They can vary in the hull, keel and sail configurations based on the primary purpose that they are intended to be used for. For over five thousand years, sailboats have been in use, whether it has been for transportation in Ancient Egypt, or for sailing events in modern times.
Technological advancements have turned the sailboat into a sleek, agile and fast vessel capable of reaching extremely high speeds by harnessing the power of the wind. Whether it be for cruises or for racing events, sailboats and other such crafts continue to be a favourite choice for sailors.
