Royal Clarence Marina is a deep-water marina situated in Gosport on the west side of Portsmouth Harbour, near the mouth of the Solent.

Owned and managed by Aquavista, it offers around 150 berths accessible at all states of the tide, making it a practical base for cruising the south coast, the Isle of Wight, or across to France.

The marina sits in a sheltered position with views across the harbour to Portsmouth's historic dockyard and the Spinnaker Tower.

Vessels entering from the Solent pass Gosport Marina, then turn into Weevil Creek just past the MOD fuelling jetty, keeping the fuel jetty to port and Burrow Island to starboard. Marina facilities are located directly opposite the pontoons on the waterfront.
