And they all laugh at how badly and scruffily we wear it.
So I decided to hit back. I asked the captain if I could wear his uniform. For special occasions.
Always game for a laugh, he said yes.
So I wandered downstairs in full captain's uniform, complete with my four stripes and captain's hat.
I got a nice round of applause. Then I realised why everyone was so happy.
There's a rule that you cannot wear hats in the officers' mess. If you do, you buy everyone a drink.
Even if I looked the part, I still don't know the navy rules.
And I didn't even win the competition. Or perhaps that's a good thing?!
