Question to the Home Office:

To ask Her Majesty’s Government which police forces in areas with North Sea coastlines or English Channel coastlines from Norfolk south and west to Devon and Cornwall have marine or boat units capable of patrolling estuaries or inshore sea waters; and what is the maximum range in which those police forces' units are licensed to operate.

The Home Office does not collect this information. Decisions on the local deployment of assets and resources, including marine units, are for individual chief constables working with their police and crime commissioner.
