The deckhand can always be counted on to get the job done whatever it may be. The deckhand is not a specialist, and tends to get stuck with the manual labor on the ship. However, they are good at helping to keep things ship-shape.
So the next time you see someone swabbing the deck or some other backbreaking job on deck just remember that they are the ones that make everyone's pirate cruise more enjoyable. Even though they will do about anything the captain asks, I don't think that these guys have been trained in the art of making towel animals like you see on many modern day cruise ships.
