We just got to Roatan yesterday and are staying in Barefoot Cay Resort & Dive Center. Three dive boats are going out twice a day and one at night.
I would be concerned about spending summers on a boat here. There is only one hurricane
hole on the island and you would be competing for anchorage space with the largest Shrimp Fleet in the Northern Caribbean
Today, there were four cruise
ships in port. So I would image that 8000-12000 tourists stepped on the island today and even if only a couple hundred wanted to dive, that would keep everyone happy.
Last year some fellow cruisers stopped here and never left.. They started a Sail and Dive Charter
business on their boat. So it can be done...
