Ipswich Wet Dock sits at the head of the River Orwell in Suffolk, reached by following the river past commercial quays and Ro-Ro terminals to a lock entrance, with the tidal New Cut branching off to port just before it.

Visiting boats are advised to avoid arriving within two hours either side of low water. A waiting pontoon lies to starboard on the approach.

Originally constructed under an 1837 Act of Parliament, the enclosed dock once covered some 32 acres and handled square-rigged commercial vessels into the 1930s.

It has since been redeveloped into a marina and waterfront quarter, and now accommodates two marinas with facilities including fuel, gas, and boat lifting to 70 tonnes. Some commercial activity continues within the wider dock area.
