Passenger ships are large vessels designed to carry people across bodies of water. They can vary in size and purpose, ranging from small ferries that transport commuters to large cruise ships that offer luxurious vacations. These ships are equipped with amenities such as dining areas, entertainment options, and cabins for overnight stays. Many passenger ships operate on specific routes, connecting cities or islands. Some famous examples include the Titanic, which was known for its luxury, and modern cruise liners like the Royal Caribbean ships, which provide a wide range of activities and destinations for travelers.
