1. CANVEY ISLAND – WASH AND DRAW-OFF DANGERS ON PUBLIC BEACHES – the usual annual warning: includes ‘jetskis’ – The foreshore and river wall on Canvey Island between the Chapman Anchorages and Scar’s Elbow is a popular public beach and amenity. For members of the public using the beaches and the river wall there are potentially serious implications from the dangers of wash and draw-off from passing vessels. Consequently, all vessels are requested to be mindful of the effects of wash and draw-off in this area, especially over the high water periods during daylight hours. Masters are reminded of the requirement under Port of London Thames Byelaw 57 that any wash or draw-off created by their vessel must not compromise the safety of others using the Thames and the foreshore. Additionally, users of personal watercraft (e.g. “jetskis”) are advised that they must not operate at speeds in excess of eight knots within 200 metres of a public beach, and that the launch or recovery of a personal watercraft from an unauthorised location (such as Thorney Bay Beach) is prohibited under Port of London Thames Byelaw 14.
