All: Is anybody claiming 1836 or earlier? If so, I've already missed it.

If we're talking Nordhoff it would be capstans and cottons screws; song and song leader; professional labour, middle management and paying passengers in one volume;… so more like coeval or contemporaneous or whatevs.

And nothing new to report in the naval science department. We've got skill positions at drummers, fifers, fiddlers, boatswains, mates, strokesmen, foremen &c &c &c but, at present, "chantyman" has not made the pay grade.
