What is the purpose of the captain's gig?

The captain's gig primarily serves as a small boat used for the captain's personal purposes, such as transportation between the shore and ship or for recreational activities. This vessel allows for ease of access and mobility, providing the captain with a means of reaching areas that may not be directly accessible by larger ships. The captain often uses the gig for official duties that require quick travel or to inspect their ship and surroundings.

The other options describe functions that are typically fulfilled by different types of vessels or boats within a maritime setting. For instance, emergency evacuations and transporting supplies would generally involve larger rescue boats or cargo ships designed for such tasks. Fishing vessels also have specific designs and equipment tailored for catching fish, which do not align with the role of a captain's gig.
