DANGER - CHAIN FERRY 

Mariners are advised that the depth of navigable water varies over the chains depending on the state of tide and the position of the ferry in relation to either the east or west riverbank. Strong tidal streams exist in this area, the ebb rate being in excess of 4 knots on the eastern side of the river on spring tides. Mariners should exercise extreme caution in the vicinity and see ADMIRALTY Sailing Directions and the latest Cowes Local Notice to Mariners at www.cowes.co.uk for further details.
