It houses a wide variety of objects relating to Hull's maritime heritage such as internationally renowned works of the art of scrimshaw, ship models, fishing and docker's tools, photographs and a large collection of important maritime paintings. These include portraits, shipping scenes and seascapes. One of the earliest is 'Molly and Friends' dated 1787, by Thomas Fletcher II, of whaling ships.
