It is absolutely clear and calm days, and wind and water are in the same direction. This is not the ideal situation for all sailors, as it is not a good amount of energy, physics. Energy is collected by the difference in movement between the wind and water. The yacht takes note of this energy by using the sail (s) and the hull (s).

Sailing and wind, as a rule, directions, and this difference is the apparent movement of the relative, or the wind. A veil of this apparent wind occurs. This is an example of a wing, and the principle of Bernoulli lift of the wing creates works much like an airplane. Indeed, under the direction of sailing boat, sailing his opinion, and can design a speed faster than the true wind speed.

With the sailing boat in a position in the water. But the possibility, in the water is useless, if management can not be manipulated. For the boat directly to a sub-component is necessary, as a sword, movie, Kiel or the body itself may be used. The combination of sailing and sub-component for movement in all directions, except in the wind.

Setting angle, the angle of start of movement in relation to the true wind, usually between 35 and 80 degrees. With an angle of 35 degrees, mounting on both sides of the wind, a sailboat could cover 290 degrees on the compass of the vessel. Sailing into the wind may indirectly veil drawn close by, about 45 degrees, then apply to sailing in a zigzag fashion. This is a good example of the veil and sub-component, in combination, in a certain direction.

Understanding the dynamics between the collection and use of energy of motion of wind and water can answer the following questions:
1) How do sailboats move?
2) How does a sailboat sail Luv?
3) How can you operate a boat faster than the wind?
Most browsers as a physicist, but they are certainly aware of physical principles, the basic movements in the water, if the sail. Without these principles, a boat and its crew would be dead in the water.
