For some good chanteys and sailors songs, including Gallic chants de marins, get Michel Colleu and Nathalie Couilloud, "Chants de Marins," Chasse/maree, which includes a cd with Stan Hugill, Stormalong John, Didier Queval, Cabestan, Djiboudjep, John Wright and others; 25 tracks.
See other threads on chanteys here at Mudcat.

There are Scots, Irish, etc. songs about fishermen, but chanteys? I agree with Anglo.
