Best source for cruising guides?
My vote for Caribbean guides would be VanSant (the entire run from the SE U.S. to VZ but absent any info of the Central/Western Caribbean), and the blossoming number of Pavlidis guides (Bahamas, T&C, Puerto Rico and soon the Windwards and Leewards, plus Trinidad).
I find the Imray series varies greatly and think those with European cruising goals need to shop volume by volume before purchasing. Both editing and writing is good in some, lousy in others.
Maybe this is just old fashioned, but I don''t find much beyond the Waterway Guide regional guides to be necessary for the U.S. East Coast.
Good luck on the reviewing and purchasing and cruising!
