Swanwick Marina sits on the sheltered eastern bank of the River Hamble, approximately two miles upriver from the entrance to Southampton Water on England's south coast.

Operated by Premier Marinas, it provides around 300 berths and offers 24-hour access to the cruising and racing waters of the Solent at any state of the tide, though first-time visitors are advised to arrive in daylight.

The marina includes a full-service boatyard with dry stack, a self-serve fuel pontoon, chandlery, and a pump-out facility. It is well connected by road via the M27 and by rail from nearby Bursledon station, with Southampton Airport roughly 15 minutes away.
