A "Windjammer" refers to a type of large sailing ship, typically a tall ship with multiple masts and square sails. These vessels were primarily used in the 19th century for cargo transport and trade across oceans. Their design allowed them to harness wind power effectively, making them popular before the advent of steam-powered ships. Today, the term "Windjammer" is also associated with a specific cruise line that offers sailing vacations on traditional tall ships. These cruises provide guests with the opportunity to experience life at sea, participate in sailing activities, and explore various destinations in a unique and adventurous way.
