As a department of Special Branch, the Marine Unit is heavily involved in daily tasks relating to the security of our coastal borders.


This involves many elements of work from patrolling important commercial and naval sites to maintaining close links with the marine community to obtain information and intelligence regarding any suspicious activity taking place.

The unit regularly visits clubs, marinas and maritime community meetings to give talks and presentations to raise public awareness on issues surrounding crime and national security.

A lot of the unit's work in this area is completed as part of Project Kraken. Click here for more information.

The unit monitors all marine occurrences reported to the constabulary and, where appropriate, uses Project Kraken bulletins and the stolenboats website to circulate marine property and crime trends to the wider marine community.

In addition to these responsibilities, the unit is involved in a large amount of collaborative work with partner agencies on the water, including the UK Border Agency (formerly Immigration and Customs departments), the Maritime and Coastguard Agency, the Fisheries Agency, harbourmasters, port authorities and the naval military police to name but a few.

Many of these bodies operate in areas of civil enforcement and the Marine Unit is often required to assist and, in some cases, intervene when matters become criminal.
