- Wind Force + Drag Force = Boat Mass * Acceleration.
The wind force overcomes the drag force of the boat.
- Drag Force = Water Pressure * Keel Area + Air Pressure* Exposed Boat Area
Most of the drag is due to the keel moving through the water. The sails, lines, mast, crew and cargo also add wind resistance.
- Wind Force = Wind Pressure* Sail Area.
The greater the wind pressure and the greater the area of the sail, the greater the wind force.

Sailboats sail in the water because of wind?
Yes... some of us refer to it as "harnessing" the wind....
A sailboat is operating under sail at night?
A sailboat can certainly be operating under sail at night. Sailboats use their sails when there is enough wind to carry them.
Sail boats and kites use what kind of energy?
Wind motion is the type of energy used by kites and sailboats.
How do solar sails tack Is it like tacking in sailboats?
Yes, just as wind on Earth transfers its momentum to the sail, pushing the boat foward, solar wind, which are very fast moving charged particles, transfer their momentum to a shuttle's sail.
How do sailboats show wind energy?
when there is a wind
What power makes sailboats move?
Sailboats are powered by wind.
What is one wind system you can use to travel around Earth?
Prevailing winds can be used to help navigate ships and sailboats around the Earth by sea.You can sail a ship around this world even against the wind using wind energy. By picking up speed using wind then use kinetic energy gained to sail against the wind direction. So, yes, even with one wind direction we can sail the globe both ways.
How does a sail work?
Different sails work differently. Sailboats tend to catch wind and cause the boat to be pushed by this action. The more square footage of sail you have the more power you are sailing with. Ice boats use the sail as a wind edge. They do better when going into a wind. The wind passes over the sail on both sides. One side has more pressure then the other side. As a result, the ice boat is capable of moving several times faster then the wind. Speeds of as much as 100 mph have been recorded.
What are the disadvantages of sailboats?
They are powerless without wind...
How do sailboats sail?
With a square rigged sail, the wind simply pushes the boat along. With a fore and aft rigged sail, the wind is caught at an angle and slices on past the sail, pushing the sail hard down wind and a bit forward. A deep keel on the bottom of the sail boat tries to stop the downwind drift and, as a result of a bit of a push forward on the sail, the sail boat manages to scoot across the wind a bit. Square rigged ship: http://sailing-ships.oktett.net/golden-state.jpg The wind just blows the boat down wind.

This is due to the wind trying to push the sail boat down wind and the bottom of the sail boat (the keel) trying to stop the drift down wind. The wind is slicing off the sails and pushes the sail boat a head a bit.
Do sailboats have motors?
Yes most ones with cabins (or places to sleep on the inside) do. Sailboats have motors just in case something happens to the sail.
Do all sailboats have a steering wheel?
No. Most small sail boats have a Tiller.
