Years at sea probably explains why I'm single. But every person in the military makes sacrifices.

Taking command of HMS Portland is definitely the highlight of my 16 years in the Navy. It is a challenge that I am fully trained for and ready to undertake.

I am very proud to be taking command of a Type 23 frigate, which is an extremely flexible warship, and I'm looking forward to taking HMS Portland on operations with a professional and focused team.

Anti-submarine warfare is the military version of chess. You must work out what the enemy is going to do before they even think of it.
