Best Answer

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 were caravels and how were they better than what they replaced?

Caravels were a type of small, highly maneuverable sailing ship developed by the Portuguese in the 15th century. They were better than the ships they replaced, such as cogs and carracks, because they had a more streamlined hull design, allowing for greater speed and agility. Caravels also had triangular lateen sails that could catch wind from different directions, enabling them to sail closer to the wind and explore new trade routes more efficiently.
