A davit is a crane-like device used on a ship for supporting, raising, and lowering equipment such as boats and anchors. Davit systems are most often used to lower an emergency lifeboat to the embarkation level to be boarded. The lifeboat davit has falls that are used to lower the lifeboat into the water. Davits can also be used as man-overboard safety devices to retrieve personnel from the water. The maintaining and operation of davits is under the jurisdiction of the International Maritime Organization, and the regulations are enforced by the countrys own coast guard.

Davits were first devised in the 17th century for use by whaling ships in the Greenland whaling grounds. They began to be introduced into Royal Navy warships in the late 18th-century and originally took the form of squared baulks of timber. Curved iron davits began to be introduced later in the 19th century. Traditionally, davits have been made of aluminum or steel, but recent advances in composite material have led to the manufacture of davits in carbon fiber, which has an excellent strength-to-weight ratio. This means davits can be stowed away when not in use, and the same davit used in multiple deck sockets fitted permanently on deck.
