This is still a very popular "touristy(?)" thing to do in Florida. There are gambling ships going out of a lot of ports, at least on the east coast. My guess would be that Florida's west coast would have their fair share as well.Later during prohibition there were gambling ships that would go off shore just outside the legal jurisdiction to let people drink and gamble. Both on the east and west coast. I know there was ship off Los Angeles that would just ferry out passengers to her for the day/night.
