Tide Mill Yacht Harbour sits on the River Deben at Woodbridge, Suffolk, occupying a horseshoe of water and pontoons converted from the old tide mill pool by boatbuilder Whisstocks in the 1960s.

The historic tide mill of 1796 still stands at the head of the marina and operates as a living museum.

Access is tidal: the river dries at low water, and entry over the sill at the marina entrance is feasible for roughly an hour or two either side of high water, with a tide gauge at the entrance showing depth over the sill.

The marina monitors VHF channel 80 under the callsign "Tide Mill Yacht Harbour." Facilities include water and electricity on the pontoons, toilets, showers, a launderette, and Wi-Fi, with boatyard services including lifts, winter storage, and maintenance.

The town centre, restaurants, and chandlery are within easy walking distance.
