What is a 2 masted sailing ship called?

A two-masted sailing ship is commonly referred to as a "sloop" or a "ketch," depending on the configuration of the sails. In a sloop, both masts are fore-and-aft rigged, while a ketch has a main mast and a shorter mizzen mast located aft. These vessels are designed for various sailing conditions and are popular for both recreational and commercial use.
