Commanding Officer

Lieutenant Commander William Edwards-Bannon

Will has enjoyed a diverse career to date, serving at sea on national and international operations – both above and below the waves – as well as in Whitehall, at the Ministry of Defence.


HMS Mersey's role

Along with her fellow River-class patrol vessels, HMS Mersey’s primary role is fishery protection. She patrols the waters of the United Kingdom and up to 200 miles of the Atlantic Ocean, ensuring that fishing boats and trawlers stick to internationally agreed quotas.

Mersey was the last ship to be built at the Vosper Thornycroft shipyard in Woolston, Southampton, for the Fishery Protection Squadron – the oldest unit in the Royal Navy.
