Ians version as well as I remember it...

Well you've been at sea a long time
must be three years or more
When we dock boy will she be waiting
like so many have before

For you look a proper sailor
done up in your number one's
You cadged a new blade from the purser
to scrape the bumfluff off yer chin

When we've set the fore and aft lines
and you hurry down the gangway
if she's waiting there, just kiss her
then turn around, give us a smile

Then we all can go ashore boy
get drunk in the clubs and bars
roll back onboard, pockets empty
like so many runs before

For a man may take a wife boy
or a man may have a mistress
but a sailor has his ship boy
and his mistress it is the sea
