Mercury Yacht Harbour sits in a sheltered, wooded setting where the shallow waters of Badnam Creek meet the River Hamble, approximately two miles from the river's mouth.

Originally built by Sir Robin Knox-Johnston, the marina is now operated by MDL Marinas and provides berthing for around 360 boats with deep water at all states of tide. Its location offers straightforward access to Southampton Water and the Solent beyond.

The Badnam Creek frontage features floating walk-ashore pontoon berthing with river views, suitable for a range of vessel types including bilge keel yachts, long-keel boats, catamarans, and motor boats.

Onsite facilities include a chandlery and the Gaff Rigger bar and restaurant. The marina is within a roughly 20-minute walk of Hamble village.
