You'll have no problem as I'm sure you well know.
We did have a bit of a problem trying to get a few places that was suppose to be 6 feet. It never made it to that depth except at high tide. I never liked to go in at high tide if I could avoid it so we missed places we were suppose to be able to get to.
With your vessel 'no problem' you'll have a great time, in the Exumas. (can you tell we didn't like the Abacos?)
Cuba? We wanted to stop there but just couldn't find the time. One thing we thought about Cuba was that since there's been not much tourism the snorkeling must be fantastic and better than any other place within 3,000 miles. No one's been snorkeling much in Cuba.
