Yacht
A modern yacht
A yacht
was originally defined as a
light, fast sailing vessel used to convey important persons.
In
later parlance, the definition came to cover a wider range of vessels,
propelled by sail, power or both and used for pleasure cruising and/or yacht
racing. Often, non-sailing yachts are also referred to as motor yachts,
to differentiate them from yachts designed for use with sail power.

Modern
use of yacht
In
modern use, the term yacht applies to two rather different classes of
vessels, sailing yachts and power yachts. Traditionally yachts were
differentiated from working ships mainly by purpose - yachts were swift and
comfortable conveyances of the wealthy and powerful. It was not until the
ascendency of the steamboat and other types of powerboat that sailing vessels
as a class became seen as luxury items. Modern use of the term yacht applies to
nearly all sailing vessels, other than sailing dinghies, that are used for yacht
racing or for pleasure cruising. www.Luxury-Yachts-Sailing.uv.ro
Motor
yachts, on the other hand, still retain more of the original sense of power and
luxury. Much larger and generally far more expensive than the average sailing
yacht, the motor yacht contains sufficient living space for at least several
days at sea. Overall length generally starts at over 30 feet (9 m) and goes up
to well over a hundred feet (30 m). Luxury yachts, such as the one owned by Larry
Ellison, can reach over 450 feet (135m), the size of a small cruise ship. The
412 ft (125 m) Royal Yacht Britannia (a steam yacht) has been retired from
service and is now on permanent exhibit at Leith.
Sailing yachts
A
sailing yacht can vary in overall length (LOA in yachting parlance) from about
6 m (20 feet) to well over 30 m (98 ft) or more. However, most privately owned
yachts fall on the range of about 7 m to 14 m (about 23-46 ft); the cost of
building and keeping a yacht rises quickly as length increases.
Monohull
yachts are typically fitted with a fixed or adjustable keel below the waterline
to counterbalance the overturning force of wind on the vessel's sails. By
contrast, multihull yachts (a catamaran is an example of this type of vessel)
use two or more hulls widely separated from each other to provide a stable base
that resists overturning.
Until
the 1950s almost all yachts were made of wooden boards, or in a larger yacht, steel
but nowadays there is a much wider range of materials. Most common is fibreglass,
but steel, aluminium and much less often because of insurance difficulties, ferrocement
are used as well. Wood is still used (traditional board based methods as well
as modern technologies based on plywood, veneers and epoxy-glues etc.) but wood
is mostly used when building an individual boat by a hobbyist or wooden boat
purist. At the other extreme, high performance yachts such as those used in the
Volvo Ocean Race and the America's
Cup are often constructed from Carbon Fibre.
Modern
yachts have efficient sail-plans that allow them to sail into the wind. This
capability is the result of a sail plan and hull design (typically a sloop rig)
that utilizes Bernoulli's principle to generate lift.www.Luxury-Yachts-Sailing.uv.ro
