Does anyone know of an island or group of islands in the Caribbean where mariners sail offshore, either fishing or coasting, without modern navigational equipment; ie, with nothing more than compass, basically? I know fishermen in Tobago and Haiti sail with only compass, but they don't go far. I've heard rumors about Carriacou but can't find info. I think the old Caribbean schooners are all gone. Any help appreciated (this is for a book on navigation). Thanks!
