Park Permits
Although applications for new permits will not be accepted for another six months, it appears that no new permits will be issued, and that the number of permits will be reduced so as not to place a burden on the coral reefs. Currently there are 236 licensed boats capable of carrying 4,000 divers a day, but this number is to be reduced to 3,000 and then 2,500, with the remainder to be taken to artificial reef systems.
