The marina is some 50Nm from the Sea Reach No.1 Buoy in the Thames estuary, therefore taking the best part of a days steaming up the Thames. Its recommended to moor overnight around the Queenbourgh area. Yachts bound for Chelsea Harbour will have pass through the Thames Flood Barrier at Woolwich - the traffic through which is controlled by London VTS (VHF Ch 14), and vessels equipped with VHF are required to call up 'Barrier Control' on passing Margaret Ness when proceeding upstream, or on passing Blackwall Point when heading downstream.
The Chelsea marina basin is controlled by a lock gate which operates ±1hrHW Chelsea. High water at Chelsea is +20mins HW London Bridge. With spring tides it may be necessary to close the outer gates around high water to control marina level.
