There aren't many occasions in the merchant marine for chanties, because the men whose muscles were used in the work in the heyday of sail have been replaced by generators, donkey-engines, electric motors, and the like.

Regardless of that, though, there's a great wealth of chanty knowledge still out there, used on ships of all kinds by people who sing them out of love for them, not because they need them for the forebit gang.

I believe they still use them for weork on some of the Barefoot Adventure sailing ships, but that's just a rumort -- I know they turn out anyone who wants to help raise sail and sing "Amazing Grace" but I don't know the details of their drills.
