Ship's boats are utility boats carried by larger vessels to act as tenders amongst other roles. Boats had different names depending on hull form, rig, size and role during the Age of Sail, this nomenclature persisting to the present, especially in military circles, long after most distinctions have disappeared.
Ship's boats that might potentially be carried by a sailing ship include:
One of the main roles of a ship's boat was to act as a taxi to move stores and people between shore and ship, and between ships. Although some boats were general purpose in nature, boats such as the Captain's gig and the Admiral's barge were for the exclusive use of officers. It was also the role of a military vessel's boats to act as landing craft, to deliver boarders and cutting-out (night attack) parties. Boats were also sometimes armed with a single bow-mounted, forward-firing, smoothbore cannon to function as small gunboats, boats so equipped would support landing operations and act as picket boats for ships at anchor.
When a ship was becalmed, mastless, run aground or otherwise unable to move, a ship's boat provided a source of motive power. The ship's anchor and cable would be rowed a distance from the ship before being laid, the crew would then man the ship's capstans to haul the ship forward, known as kedging or warping, this would be repeated as many times as needed.
The ship's boats could also when needed be used as a lifeboats and rescue boats.
During the age of sail the ship's boats of larger ships of the line would be stowed upon the deck, sometimes nested one atop the other. Boats would be deployed and recovered by davits with some vessels carrying a single small boat suspended astern. In the smallest vessels a ship's boat was also on occasion towed astern. Boats stored on deck in tropical climates were usually partially filled with water to prevent the wooden hull planks drying out and shrinking, which would make the boat leak once it was placed in water until the wood swelled up again.
