The Port of King’s Lynn offers visitors direct access to short term mooring pontoons for a maximum draft of 1.5m with no bridge or locks to navigate.

Always ensure your craft is moored sufficiently to cope with the strong tidal flows which on big spring tides will reach up to 7 knots for a while. Commercial ships may come very close to the pontoons as they swing during busy tides and fishing craft heading to / from Boal Quay may be encountered at speed well before & after high water. There are no moorings available alongside any of the quays in King’s Lynn for any leisure craft and the quay immediately to the south of the pontoons is an emergency lay by berth for ships up to 85m long, as well as short term visits for any commercial vessel. Vessels with greater draft or commercial vessels contact the King’s Lynn Conservancy Board on (01553) 773411 or ABP King’s Lynn (01553) 691555.
