Why do ships have sails?
Ships have sails to catch the wind and propel them through the water. Some modern vessels have sails out of nostalgia for the older sailing methods, while the actual historical vessels had no engines and, therefore, depended on the wind to carry them. They are testing a type of sail that looks more like a large kite or parasail. They are to be used by large ships to help lessen their fuel consumption. It has been tested on Super tankers

What did Vespucci's ships look like?
Fifteenth century ships, such as those Vespucci sailed on were large, and constructed of wood, with numerous billowing sails. The ships were sometimes reinforced with metal to make them more seaworthy. These ships were highly dependent upon wind being strong enough to maintain constant sailing, yet not too strong as to damage the ships.

Which is the best sail form between a form of a Circle or Hexagon or Triangle or a square?
Like all things in life this depends entirely on what you want to use it for. Circles or hexagons, however, would be far too impractical to be of any use due to the number of lines/spars that would be needed to maneuver them. Although that being said, if you wanted to make a sea anchor (like a parachute for the water) they would be the best shapes to use. That leaves us then with triangles and squares. If you want to head up-wind triangle sails are the most common and useful as they are often much easier to maneuver when tacking into the wind. [See http://wiki.answers.com/Q/What_is_tack_in_sailing for the definition of tacking] However if you are traveling down-wind, you typically don't need to change course as often and square sails allow you to catch more of the wind than the triangle sails. Because of their different uses and the ways that they are rigged, triangle sails are typically called "fore and aft" sails, and square sails, are unimaginatively called square sails. As a side note, sometimes quadrangular sails are also used as fore and aft sails (such as a gaff rigged main) and these can have the advantage of catching more wind, however it adds to the complexity of the rigging, as well as the number of people typically needed to raise/douse(lower) them. Anyways, hope that helps!

What did Juan Ponce de Leon's ship look like?
Juan Ponce de Leon's famous expedition to Florida included three ships. Two were caravels; the Santiago, which was the flagship, and the Santa Maria de la Consolacion. The third was the brigantine San Cristobal. Brigantines were smaller and could go closer to shore than the caravels could. Caravels of that time were of two forms. The older style was 'lanteen' rigged, meaning it carried two triangular sails in a form adapted from qarib ships used by Muslim explorers, and a newer square-rigged style called 'caravela redonda' by the Portuguese, in the Iberian (Spanish) style. Some caravels could mount either kind of sail, or both at once, square sails above and triangular ones below, fore, and aft. One existing drawing (see link below) shows that the Santiago and the Santa Maria de la Consolacion were of this newer, square-rigged type, perhaps with square sails at topmast and lanteen sails below. A caravela redonda like the Santiago might be as much as 30 meters long, carry three or four masts (the drawing seems to indicate three masts) and a few cannon. These caravels had no forecastle (the raised section on the front of the ship) and a shorter sterncastle (the reaised section to the rear of the ship) than the earlier 'carrick' design. This made them handle much better at sea. this is a gay answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
