Our navigational safety team is headed by our Chief Harbour Master who has overall responsible for defining and enforcing the regulations needed to support and manage the safety of navigation on the 95 miles of the tidal River Thames. Given the extensive length of river we cover, and the very diverse uses it is home to, day to day management of the river is overseen by two district Harbour Masters who cover the river between Teddington Lock and Crossness (around Dagenham) and Crossness and the outer estuary, respectively.
