Continuing 1840s shipboard,

We have this reference, courtesy of Lighter, to a song in a whaleman's diary, Sept. 11, 1842.

       The Taskar is the thing to roll
       O ee roll & go
       Her bottom's round as any bowl!
       O ho roll & go

The author was aboard the whaleship TASKAR. (Reproduced in Margaret S. Creighton's "Rites and Passages," 1995, p. 178).

It is not indicated (?) whether this was a work-song, but it certainly looks like a chantey form. There are relly not enough details to contextualize it, though the "roll and go" may connect it to known chanties.
