(LNTM 13(T) of 2017 is hereby cancelled)Notice is hereby given
that further commissioning works have been carried out by the Isle of Wight Council, to re-establish a continual service throughout the tidal cycle whilst minimising the effect on the safety of navigation.
Hydrographic surveys to measure clearance over the chains have been undertaken and the following temporary restrictions are in place:Maximum Permissible Draught = Actual Tide Height + 1.0metres
Mariners are advised that this is a ‘worst case’ (mid-ebb spring tide) when the ferry is being set to the north and that increased clearances are possible during the tidal cycle, particularly at High Water. Please see the draft indicative survey diagrams below.
All mariners are reminded that the maximum clearance depths are achieved at the mid-point between the prow of the Chain Ferry and the opposite shore. Vessels should avoid passing close to the prows of the ferry due to the obstruction of the chains as they slope down to the riverbed.
Any deep draught vessel or any other vessel requiring an unimpeded passage should contact the Chain Ferry, providing as much notice as possible, on VHF Channel 69.
Further chain adjustments and survey checks are scheduled for Monday 10th July, with the aim of increasing depths over the chains throughout all tidal cycles whilst maintaining a normal ferry service. The aim of these scheduled works will be to restore navigation clearance depths over the chains to previous reported depths for the previous ferry. Further surveys will be carried out as works require and all mariners will be advised of any changes to clearance depths via Cowes Harbour Local Notice to Mariners.
All mariners are advised that Cowes Harbour LNTM 15 of 2016
remains in force and all vessels should navigate with particular caution when approaching the Chain Ferry, especially with a following tide.
