Mistaanis, we don't have much to go on there... You'd be referring to the charts in what country ? Might be one way to narrow down the search.
The line you cite sounds a bit Creole (mix of French and a lot of other bits spoken in the islands of the Carribean under French influence - Martinique / Guadeloupe / Haiti... )

Then, of course, there's a port in Brittany (I think - strike me down Normandy, if it's not) called Saint Malo..

Can you come up with any more of it to help us ?
