We are not jesting Dennis, we are deadly serious.
If a warship carries aeroplanes, it sure as hell ain't a boat!
Submarine? I'll give you that one as submariners will tell you they go to sea in a boat, and not a ship. And that's why I served in aircraft carriers. I wouldn't go underwater for all the tea in China.
Which brings me to another moan: sailors go to sea IN a ship not ON one one.
Why? Because a ship is his home and you don't live on a home, you live in one.
