Ocean liners are subdivided into passenger liners and cargo liners.
Passenger liners are ships designed to carry people across the ocean, typically for commercial purposes. These ships are equipped with various amenities to make the journey comfortable for passengers, such as restaurants, bars, and entertainment facilities.
Cargo liners, on the other hand, are ships designed to transport cargo across the ocean. These ships have large cargo holds and are equipped with cranes and other equipment for loading and unloading cargo.
While some ships may carry both passengers and cargo, the primary purpose of the ship determines its classification as a passenger liner or cargo liner. Therefore, ocean liners are mainly subdivided into passenger liners and cargo liners.
