The following diagram of the Fobbing flood defence barrier shows the Gates labelled with their number. 

Whenever Gate 2 or Gate 3 is undergoing works, the gate will be lowered into the defence position, marked with yellow & black tape and illuminated at night. The barrier structure fixed warning beacons may also operate. During these times, the Fobbing barrier remains open to navigation, with vessels required to navigate through the open span width.  

Mariners are advised to proceed with caution at a safe speed, keeping clear of the lowered gate and keeping a sharp lookout for other craft and for workers and equipment involved in these works and being aware of the available depth of water taking into consideration the height of tide.
