In one of the several discussions of chanties not too long ago, I mentioned having seen a film about a Portuguese ship fishing off Newfoundland - I can't find that discussion now, but I have found what could well have been the film in question ('twas in another lifetime): https://www.youtube.com/watch?v=ELfR82zk08Y

The ship is the Gazela, which I gather some of you are familiar with.
