I was surprised to learn that there are a good number of retired couples (like us) who have escaped "normal" retirement to buy a boat and cruise the world year-round. But there are also younger couples with young kids doing the same. Their kids are home-schooled and getting a world-view not typically experienced by most. In Grenada right now, there are families from England, South Africa, Brazil, Australia, France, Sweden, Germany and the USA. There is even a "kid's net" that comes on the VHF radio once a week--run by kids, following the daily "cruiser's net"--where they welcome new arrivals, say goodby to kids leaving, plan social get-togethers on each others' boats or ashore. I suspect that in 10-15 years, these pretty sophisticated kids will be stepping in to save the world from itself...
In the interim, they have in common the English language, the joy of cruising--and candy. Last evening, on Halloween, they formed a flotilla of dinghys and went trick-or-treating from anchored vessel to anchored vessel here in Prickly Bay.
Rick and Linda Grimes bought a sailboat and left the U S of A for the Caribbean in 2015.
