A lifeboat is a small, sturdy, or inflatable boat used for emergency evacuation in the event of a ship disaster. According to the law, large commercial ships are required to conduct lifeboat drills. Life rafts can also be used. These small boats can sail safely. The Convention for the Safety of Life at Sea (SOLAS) and the Life Saving Equipment Regulations (LSA) both require ships on voyages to be equipped with lifeboats. Modern lifeboats are equipped with emergency position indicating radio beacons (EPIRB) and radar wave reflectors or radar interrogators.

An air box is installed under the seat plate inside the boat to ensure that the boat is fully filled with water and will not sink. The boat is equipped with food, drinking water, first aid supplies, accessories, communication equipment, as well as propulsion devices such as sails, oars, and poles, and some are also equipped with motorized propulsion devices. According to the structural materials, they are divided into wooden lifeboats, metal lifeboats, and fiberglass lifeboats. According to their structural form, lifeboats are divided into open, closed, and fully enclosed types. The length shall not be less than 5m. Motor boats shall be propelled by oars, sails or machines, with a crew of 60 or more people. The Convention for the Safety of Life at Sea and the Code for Marine Life Saving Equipment have strict regulations on the equipment, strength, buoyancy, stability, and unsinkability of ship lifeboats. At the same time, it is required that all lifeboats on passenger ships must be able to land in the water within 30 minutes under normal weather conditions. The ship can safely land even in unfavorable longitudinal or lateral inclinations of 15 degrees on either side; The arrangement of lifeboats should not hinder the operation and use of other life-saving equipment, and all lifeboats should be immediately available in emergency situations. The bow of the lifeboat indicates the name and number of the vessel, and the stern indicates the port of registry. The lifeboat is usually set up on the hanging equipment on the lifeboat deck for personnel to board and quickly release to the water surface.
