The Mizzen Boom

I saw a boat called Mary and she bobbed out in the bay
Mary has some barnacles, they'll have to go some day
But meanwhile Mary sails along, her crew is all aboard
Her Captain has the maps out and he's making for the shore.

I saw a boat called Mary and she bobbed out in the bay
Mary'd had a lick of paint at dry-dock in Calais
She sailed as clean as ever through the water, blue and white
The Captain and his bosun swung the boom and hung a right.
