All inward bound vessels making for the marina should report to the Ipswich Lock Control on VHF Ch 68 before passing under the Orwell Bridge. Vessels will be advised on lock information and the direction of the waiting pontoons if required. At this point you may also call the marina for available berths on VHF Ch 80
Access to the marina is via the Prince Philip Dock, which is protected by flood gates, which may be closed during exceptionally high tides, which means that navigation to the marina will be closed. Entry in and out of the lock is controlled by a traffic light system:
single GREEN light: clear to enter
single RED light: no entry
There is free flow through the lock at certain high tides and the traffic signals still apply.
