Sailboats
by Zach
Sailboats
are the only type of boats that use the wind to propel themselves
forward. Some sailboats
have a motor, but usually it’s a sail that moves them.
People
mostly use sailboats for enjoyment.
Small sailboats can cost as much as $1,500 and can only be used
for short trips. More expensive sailboats can come equipped with complete living
quarters for two or more people. These sailboats can be used for longer vacations or even
trips around the world. Some
people like to have fun by racing their sailboats.
There are many rules to help prevent collisions during a sailboat
race. Most races are held
on lakes where the competitors race in triangles.
Sailboats
move by positioning the sail depending on the way the wind is
blowing and which direction you want the boat to go.
When the wind is blowing from the back of the boat, you simply
set the sail directly across the boat.
You do that so the sail fills with as much wind as possible and
the boat moves forward. If
sailboats could only go the same direction as the wind, they wouldn’t
be very useful. When the
wind is coming from the front of the boat, and you don’t want to go
backwards, you have to position the sail to move on a diagonal so you do
not go directly into the wind. By
making right and left turns you can always keep the wind on an angle in
front of you but not directly at you.
This type of maneuver is called tacking.
Each part
of a sailboat is very important. A
sail can be many shapes such as a rectangle or a tall triangle.
They are usually made out of canvas or nylon.
The sails are attached to long poles called masts.
These masts have ropes that lower and raise the sail.
The mast is attached to the main part of the boat, called the
hull. Passengers ride in
the hull. At the back of
the hull, the driver of the sailboat steers using a device called a
rudder. The rudder moves side to side and helps direct the boat.
Attached to the bottom of the hull is another piece of wood or
fiberglass that is like the rudder, but it does not move.
This is called the keel. The
keel is there to stop the boat from moving sideways in the water when
the wind is pushing on the sail.
