200 Million Dollars Yacht In The Worlld Which Belongs To One Of The Founders Of Microsoft, Paul Allen

Yacht lengths generally range from 20 feet (6.1 m) up to hundreds of feet. A luxury craft smaller than 40 feet (12.19 m) is more commonly called a cabin cruiser or simply "cruisers." A mega yacht generally refers to any yacht (sail or power) above 100 ft (30.5 m) and a super yacht generally refers to any yacht over 200 ft (61 m). This size is small in relation to typical cruise liners and oil tankers.
History
Yacht (/ˈjɒt/, from Dutch/Low German jacht meaning hunting or hunt, compare Standard German/High German Jagd) was originally defined as a light, fast sailing vessel used by the Dutch navy to pursue pirates and other transgressors around and into the shallow waters of the Low Countries. They were also used for non-military governmental roles such as customs duties and delivering pilots to waiting ships. The latter use attracted the attention of wealthy Dutch merchants who began to build private yachts so they could be taken out to greet their returning ships. Soon wealthy individuals began to use their 'jachts' for pleasure trips. By the start of the 17th century 'jachts' came in two broad catergories- speel-jachts for sport and oorlog-jachts for naval duties. By the middle of the century large 'jacht' fleets were found around the Dutch coast and the Dutch states organised large 'reviews' of private and war yachts for special occasions, thus putting in place the groundwork for the modern sport of yachting. Jachts of this period varied greatly in size, from around 40 ft (12 m) in length to being equal to the lower classes of the ship of the line. All had a form of fore/aft gaff rig with a flat bottom and lee boards to allow operations in shallow waters. The gaff rig remained the principal rig found on small European yachts for centuries until giving way to the 'Bermudan sloop' rig in the 1960s.
