Most of the time. Some are powered by motors, but all of them have the sails (different numbers for different kinds of ships). The wind catches in the sails and moves the boat. Depending on the angle of the sail, the ship can move in almost any direction. Though it is easiest when the wind is right behind the boat. When the wind is blowing in the opposite direction you want to go, then there is a technique that you can use called "tacking".

Vasco Da Gama's ship was powered by the wind, it was a sailing boat.
a boat a sail and the wind
Sailing is a sport that requires the changing of the rigging and rudder on a boat to change the direction and speed of the boat. The boat is moved by wind against the sails.
A boat can sail into the wind by sailing backwards and forwards (tacking) at an angle to the wind and so making her way up.
Well. A wind powered vehicle is a vehicle that is powered by the wind obviously. An example of a wind powered machine would be a sail boat, a kite perhaps, or a hang glider.
Wind powered (i.e., sailing) vessels.
The answer is: We love the wind, we love the sun, sailing a boat, is yachts of fun
The best point of sailing is 45 degrees to the wind. If the wind was over the beam you would have to take a port or starboard tack to it.
A sailing boat can not sail directly upwind, sail at about 45 degrees to the wind and tack (turn the boat through the wind) to the other side of the wind and continue in this zig-zag manner up wind.
No. The fastest point of sailing is the broad reach whether it be starboard or port. Actually, it depends on the boat. Each boat has a polar diagram which indicates the fastest point of sail. Sailing dead down wind is very slow, since the wind has to push the boat through the water. "Beating into the wind" or sailing close to the wind usually isn't the fastest either. The physics of the sails and keel (or dagger board) cause the boat to squirt forward - much like a watermelon seed squirts through your fingers if you pinch it. Racers take advantage of the physics of the boat and know exactly the angle to the wind to sail fastest on starboard and port (as they may vary by a few degrees).
A sailing ship is referred to nowadays as any large wind-powered vessel. Generally you will find that these ships are completely powered by a series of masts and sales.
