HarveyO:My reading of the latest handout in the newspaper (which may be full of it) leads me to believe that you can dive there. As a private party. But there cannot be any commercial activity. So if you can get a non-commercial boat to take you out for a dive you're in business.
The big trick would be finding a non-commercial boat that could even make the trip. You'd need a sailboat most probably. I dont think the typical recreational gas or diesel vessel has the fuel capacity to do much of the archipelago.
