Lastly, from Clark, 2 more windlass chanties are mentioned:

In c.1865-1866, Clark was on the NASON, a fishing schooner (I assume?) out of Provincetown, sailing off the Grand Banks.

"Every man sprang to duty. The cheerful chanty was roared out, and heard above the howl of the gale. The cable held very hard, and when it surged over, the windlass sent the men flying about the deck, as if a galvanic battery had been applied to their hands. The vessel's head was often buried in the solid seas, and the men, soaked and sweating, yelled out hoarsely, " Paddy on the Railway," and " We 're Homeward Bound," while they tugged at the brakes, and wound the long, hard cable in, inch by inch."

Note that he uses the word "chanty."

That word is used elsewhere in the text -- in other contexts.

Here he is referring to stevedores, in Zanzibar:

A chanty gang was engaged to hoist out the cargo, and one of them in trying to steal hard bread, finding the bull-dog upon him, jumped overboard and swam safely ashore.......
The chanty men wanted biscuit, and waited to receive them.

So, "chanty men" and "chanty gang" had become a general term for stevedores.

In c.1866, is is about to leave St. Jago, Cuba. He notes at one point,

The Cubans have no real, go-ahead enterprise. The whites never perform any labor, but leave it to the slaves and coolies who do it all.

He is to leave on a Yankee schooner...

...when the sugar began to roll in, the crew found I was at the head of the rope, and a "chanty man." We rolled the sugar upon the stages, over the bows, and at every hogshead I gave them a different song. We worked hard all day, and generally had time at night to go ashore.

Clark, aka "Yankee Ned," was very familiar with chanties, then, and even refers to himself indirectly as a "chanty man" -- in this case, meaning someone who can lead chanties. He does put the phrase in quotes here, suggesting that maybe (though he doesn't define it for the readers) wants to mark it off as a particular usage.
