What is a davit used for on a ship?

A davit is a device used on ships primarily for handling lifeboats and other equipment that needs to be lowered or raised over the side of the vessel. Its design allows it to be swung out, providing a safe and efficient method for deploying lifeboats during emergencies. When utilizing a davit, crew members can securely handle the weight of the boat while ensuring that it is properly positioned for lowering into the water.

In the context of shipboard operations, the davit plays a critical role in safety and emergency preparedness, as it facilitates quick access to life-saving equipment. While other options mention functions that are important on a ship, none of them accurately describe the primary function of a davit. For instance, raising sails is related to rigging and does not involve the use of a davit. Similarly, navigational tools pertain to the ship's navigation system, while locations for emergency equipment focus more on storage than the mechanism for deployment. Therefore, the definition of a davit as a shipboard crane that can be swung out over the side is the most accurate and relevant choice.
