Sail
is a triangular piece of cloth tied to the mast of a ship in such a way
that it help the ship to propel in the direction of wind. Sails were
used in sailing since a long time back when there were no engines to
drive the ship.
Sail is actually a piece of fabric sewn together and fitted to the
spars and rigging of a vessel so as to convert the force of the wind
into forward motion of the vessel. The smaller sizes are ideal for high
wind freestyle, and the entire range has the lower center of effort, and
fine balance associated with the shorter outline.
Use of sails
Sails are primarily used as propulsion system at sailing ships. During
ancient periods when engines weren't invented, sails were the prime
material for driving the ships. Subsequently sails were replaced, but
they are even used for recreational purpose.
Materials
of Sail
Initially sails were made of hemp or cotton. But as technology improved
further new materials came into existence which were best suited for
sails. Now sails are made from polyesters (Dacron and PET film),
sometimes reinforced with crystalline hydrocarbons (Spectra &
Kevlar). Polyamides (nylon) are also used for manufacturing large, light
weight sails.
Parts of sail
Sails are almost triangular in shape and the different parts of sails
have a common terminology. A sail has different names for each corner
and edge. We can divide it in two sections :

clew and tack.
- Edges: The lowest edge of sail is known as
foot. The forward edge is called the
luff. Leech is the third edge of a
sail.
