The Inner Marina is the tidal section of Ramsgate's Royal Harbour, accessed via dock gates and a lifting bridge approximately two hours either side of high water. A red and yellow flag by day, or a single green light at night, signals when the gate is open.

The basin maintains a depth of 3 metres and is used primarily by permanent berth holders rather than visitors. The entrance to the inner harbour lies roughly 300 metres northwest of the main Royal Harbour entrance, between the heads of the West and East Piers.

Marina staff can be reached on VHF Channel 80. Ramsgate town centre is a short walk away, offering shops, restaurants, and public transport connections.
