The museum is housed in the early 19th century Grade II* Clock House at the Royal Harbour, Ramsgate. Four galleries present aspects of the maritime heritage and seafaring life of the Isle of Thanet and East Kent through displays on Royal Harbour history, fishing and shipbuilding, navigation and the lifeboat service. The important marine archaeological collection features artefacts raised from the notorious Goodwin Sands, featuring arms and effects excavated from the late Stuart warship Stirling Castle, sunk in 1703. A fifth display and conservation area - The Gun Room - houses a huge iron gun undergoing preservation, with an accompanying exhibition on Naval Gunnery.
In the John Rennie Room can be seen the Ramsgate Meridian Line while, adjoining the main building, Smeaton's 1791 Dry Dock and historic craft including the 'Dunkirk Little Ship' Sundowner can be seen
