A yacht jɒt is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities.
The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are: —carrying no more than 12 passengers, —solely for the pleasure of the owner and guests, or by flag, the country under which it is registered. A superyacht (sometimes ) generally refers to any yacht (sail or power) longer than .
Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020 there were more than 15,000 yachts of sufficient size to require a professional crew.
The term, yacht, originates from the Dutch word jacht (pl. jachten, which means "hunt"), and originally referred to light, fast sailing vessels that the Dutch Republic navy used to pursue pirates and other transgressors around and into the shallow waters of the Low Countries.
The history of pleasure boats begins with rowed craft in Pharaonic Egyptian times, and other vessels in the waters of Burma, India, Mindanao and Japan. Anglo-Saxon royal pleg-scips (play ships) of the 8th-century featured ornamented bows and sterns and had the capability of cooking on board.
The history of sailing yachts begins in Europe in the beginning of the 1600s with the building of a pleasure vessel for the son of King James I of England. While other monarchs used naval ships for transportation and conquest, James I was the first English monarch to commission the construction of a yacht—for his son Henry, Prince of Wales in the early 1600s. Pleasure vessels acquired the name yacht after the time of Charles II, who spent time exiled in Europe and visited the Netherlands, where a variety of jachten were already well developed as pleasure boats for the elite classes since the beginning of the 17th century.

Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. Human-powered paddles and oars, and later, sails were the first forms of marine propulsion.
Yachting is recreational boating activities using medium/large-sized boats or small ships collectively called yachts. Yachting is distinguished from other forms of boating mainly by the priority focus on comfort and luxury, the dependence on marinas for docking, and being typically only for exclusive social leisures such as cruising, fishing trip or racing. The term "yacht" derives from the Dutch word jacht, meaning "hunt". When yachting with sailboats, the activity is simply called sailing; and with motorboats, it is called powerboating.
The America's Cup, informally known as the Auld Mug, is a trophy awarded in the sport of sailing. It is the oldest international competition still operating in any sport. America's Cup match races are held between two sailing yachts: one from the yacht club that currently holds the trophy (known as the defender) and the other from the yacht club that is challenging for the cup (the challenger). Matches are held several years apart on dates agreed between the defender and the challenger.
In this work, various aspects concerning the numerical simulation of a sailing boat are investigated. The attention is focused on simulation of the free-surface, the fluid-structure interaction (FSI) between wind and sails, and the dynamics of the whole bo ...
The numerical simulation of free-surface flows around sailing boats is a complex topic that addresses multiple mathematical tasks: the correct study of the flow field around a rigid hull, the numerical simulation of the hull dynamics, the deformation of th ...
