Absolutely, but in terms of pure ethnomusicological context the function of sea shanties these days is very different from that they were designed for, although the moany, plaintive, with plenty of solidarity-building call-and-response aspect endures, though more in terms of communal communion with collective faith romance. I'm cool with that; nothing I like better than joining in on a good shantie / chantey at full throttle even though I get sea-sick on the Knott End ferry. The romance of the thing is a very joy. Same with Folk Song as a whole really...
