Pronunciation: [skwˈe͡ə sˈe͡ɪl] (IPA) 
Square sails have been used since ancient times to propel boats and ships across the seas. Synonyms for the term "square sail" include "course sail," "main sail," and "skysail." The course sail, the largest square sail on a ship, is situated just above the deck and extends from the mast to the bow. The mainsail, on the other hand, is attached to the mast and the boom, and extends from one side of the boat to the other.

Each of these sails plays an important role in maritime travel and has its own unique characteristics and uses.
