Throughout history sailing has been instrumental in the development of civilization, affording humanity greater mobility than travel over land, whether for trade, transport, warfare, or the capacity for fishing. The earliest representation of a ship under sail appears on a painted disc found in Kuwait dating between 5000 and 5500 BCE.
A traditional modern yacht is technically called a "Bermuda sloop" (sometimes a "Bermudan sloop"). A sloop is any boat that has a single mast and usually a single head sail (generally a jib) in addition to the mainsail. The Bermuda sloop sailing vessel was developed on the islands of Bermuda in the 17th century. Find out more at Wikipedia.
