Come away, fellow sailors, come awayThis continues with some variation on "But never intending to visit them more," but otherwise that's the entirety of the text. I guessed at the line breaks, judging by what words receive capital letters in the notation I have (found here).
Your anchors be weighing
Time and tide will admit no delaying
Take a bowsey short leave of your nymphs on the shore
And silence their mourning
With vows of returning
But never intending to visit them more
"Mourning" and "returning" don't rhyme perfectly. At best, it's a slant rhyme. That imperfection in rhyming seems to betray the sailors' "never intending to visit them more." If there were a perfect rhyme there, it would imply the sailors' faithfulness to their "nymphs on the shore."
