I'm in Antigua now, but haven't talked about fishing with my friends (I have to admit, I forgot about it and just now saw this thread again). Almost all of St. Barths is declared a nature preserve and much of St. Martin is as well. These areas are well-marked on the charts and also have yellow buoys demarking the borders. On a rhumb line from Antigua to St. Barths there are some wonderful shallows for fishing, because I always see fishing boats out there and also a lot of fish pots. It is about 35 miles to St. Barths, and 35 back to Antigua.
