Unless you start your own charter business they prefer to hire locals that know the reef. As far as getting your Captains license here it requires residency and a trip to the port captain to get a form, go to the bank and pay about $5 and bring the form back. Done! That also explains why many people driving boats here drive like maniacs and don’t follow the rules of the road. I have my uscg captains license as well and unless you’re on a us flagged boat it won’t matter.
