I'm new here, and don't know this particular song. But for what it is worth, I have access to Bullen's book.

Although Bullen categorizes the song with windlass and capstan shanties, he says he first heard the song when discharging cargo at the Demerara River off of Georgetown in Guyana, on his first voyage (which began in 1869). He liked the song so much he made a special point of learning it. However, he also reports that he never heard the song anywhere else and that it was "not in common use on board ship." This is consistent with what Hugill says about it: his friend Harding told him that it was used on shore in the West Indies.
