Sailing

Motion across a body of water in a floating vessel? powered by wind (the force is used to create motion by using one or more sail?s).

In ancient times (See Odysseus), the boat had to use rear wind (propulsion) and therefore wait the right wind directions to start its cruise

Modern sailing boats are able to go against the wind from an average of 40 degrees, to 25 degrees for modern (America's cup type) racing boats.

Sailboats typically have one, two, or three hulls. Vessels with one hull are known as monohull?s, those with two or more are known as multihulls. Multihulls can be further subdivided into catamaran?s (two hulls), and trimaran?s (three hulls).

Sailing can be further divided into two areas:

Racing? and Cruising?
