I am the Captain of My Boat

I am the captain of my boat on a calm, a calm and peaceful sea
I am the captain of my boat on a calm, a calm and peaceful sea
With waves so still I'm seldom ill, with stars and sun my work gets done
I am the captain of my boat on a calm, a calm and peaceful sea

There are equal captains, equal boats, that never sail and never float
On stormy seas with wind and hail the boats get smashed and captains jailed
There are captains who are just like me who die upon a violent sea
So credit not my boat or me but a calm, a calm and peaceful sea
