Starting at the end of the 19th century they were gradually replaced by the boats that used steam to generate motion. Today, sailing is a hobby some people have. In some regions of the world, sailing vessels still keep their importance. 
Many military forces also have sailing vessels for the purpose of training. 
Sailing is also a competitive sport. It is one of the sports in the Olympic Games.
