Chantey

Larkin's poem, The North Ship, came to mind, the one that begins:

I saw three ships go sailing by, 
Over the sea, the lifting sea, 
And the wind rose in the morning sky, 
And one was rigged for a long journey.

Except that this was evening, not morning, there was no wind, the ships (ferries) were coming in to port and none were 'rigged for a long journey.' Still.
