We’ve been chartering since our first was 9 months old. We now have a 2 and 4 year old.

Things that work for us.

1. Keep the sailing early and short. 2 hours in the morning. Then it’s play and beach time.
2. Yes, PFDs. Mustang. Our kids are fine with them. Be persistent. Always on while underway. Once moored it’s play time.
3. I rig a cockpit jack line and clip them in.
4. Pack and play right on the bed. Check out Guava brand. Nice and compact.
5. At a young age a front pack will work.
6. I heard a car seat is useful to buckle them in if needed. We never brought or used them.
***7. Charter out of St Thomas. CYOA. 7 minute taxi ride. No ferry needed. Peace of cake.

Have fun.
