A passenger ship is a ship specially designed to carry passengers and their luggage and mail. A passenger ship that also carries a small amount of cargo is also called a passenger cargo ship. Passenger ships are mostly regularly scheduled sailing, also known as liners or cruise ships. Under the SOLAS Convention, any ship carrying more than 12 passengers is considered a passenger ship. The passenger ship is characterized by a superstructure with multiple decks, complete restaurants, sanitation and entertainment facilities, and adequate life-saving equipment, fire-fighting equipment and communication equipment. Some passenger ships are also equipped with anti-rolling devices to improve the navigation environment. The speed of passenger ships is relatively high, generally 16 to 20 knots, and large high-speed passenger ships can reach about 24 knots.

A ship carrying passengers as well as baggage and mail. Passenger ships generally carry both passenger vehicles and small quantities of cargo. The basic characteristics of passenger ships are: developed superstructure, used to arrange passenger cabins; anti-sinking, fire prevention, life-saving and other aspects of safety requirements are more stringent; anti-rolling, shock absorption, sound insulation and other aspects of high comfort requirements; faster speed and power reserve. The vast majority of passenger ships sail on regular routes, which are also called liners. With the development of long-distance air transportation, passenger ships gradually turn to serve short-distance transportation and tourism. Passenger ships can be divided into the following five categories. A traditional passenger ship sailing on rivers and lakes. Large passenger capacity, frequent docking, mostly in the floating dock through the bulwark door loading and unloading small quantities of groceries and mail. The main structure is relatively thin. If the velocity of the flight segment is less than 3 meters per second, double bottom may not be set. Generally, there are two decks with lower freeboard, and the safety requirements are lower than those of sea-going ships due to convenient strain in the flight section. The superstructure is mostly extended head to tail and outboard to increase the passenger area. Most of them are double-propeller double-rudder or triple-rudder. Today, the speed of large ships in shallow rivers and lakes is generally 12 to 16 nautical miles per hour. The inland river passenger ships on the main line of the Yangtze River in China are mainly "Dongfanghong", with a length of 113 meters and a total tonnage of 5050 tons. They can carry 1250 passengers and have an average speed of about 25 nautical miles per hour.

Small high-speed passenger ships appeared in the 1960 s with high speed and short-range passenger ships, mostly sailing between straits and islands. The hull and main engine are smaller and lighter. The speed increased from 18 knots per hour in the early days to about 27 knots. Hydrofoils and hovercraft are also small high-speed passenger ships that can sail on rivers, lakes and straits. In 1980, Japan made a small waterline plane catamaran passenger ship, which supported the cabin deck with small cross-section pillars on two floating bodies submerged in the water, making the hull high above the sea surface, reducing wave disturbance to the hull, improving seaworthiness and increasing speed.
