A davit system is a type of crane used to deploy and recover lifeboats, tenders, and other watercraft from a ship or offshore platform. The name "davit" originates from the Old French word "daviot," meaning a small boat. Davits are typically mounted on the deck of a vessel and consist of a swinging arm or boom that extends over the side. They are operated either manually or mechanically, with electric or hydraulic power being common for larger systems.

The primary function of a davit system is to safely lower a lifeboat or tender into the water and to hoist it back up for storage. This is a critical safety feature, especially in emergency situations. Modern davit systems are designed to be robust and reliable, capable of operating under challenging weather conditions. They often incorporate features such as fall prevention devices and load-limiting mechanisms to enhance safety.

There are various types of davit systems, including gravity davits, radial davits, and pivot davits, each with its own operational characteristics and suitability for different vessel types and applications. Gravity davits are common for lifeboats, using the weight of the boat to assist in its deployment. Radial davits are often used for smaller tenders and can be swung out from the deck. Pivot davits, also known as hinged davits, are characterized by their pivoting motion. The selection of a davit system depends on factors such as the size and weight of the craft being handled, the space available on deck, and regulatory requirements.
