The only one I'm aware of is the "Cruiser's Guide to Newfoundland", put out by the Cruising Club
of America. You can find it online by Googling the obvious key words. They have just put out a version updated to 2014. A very excellent and useful guide. The ATL-series coast pilots put out by the Canadian Government
and available from any chart agent are also very useful, and fill gaps here and there in the cruising guide. I would by all means secure both.
