The only country we know of that insists on seeing US federal documentation papers is Guadeloupe, and specifically the little bay/village called Deshaies. We have not heard of any problems with the other French islands, including Martinique. What has happened in Deshaies is that the local Gendarme who is responsible for checking you in fined the boat for not having the correct documentation and demanded that the boat leave immediately.
All US and current and former British islands accept state registration.
A quick look at the countries section of Noonsite - www.noonsite.com
- makes no mention of the problems with paperwork in Guadeloupe. It's been a long time since we've been there, and perhaps the difficult gendarme has retired. ???
Although EU, US, and Canada citizens have no problem with entry into the islands of the Caribbean, there are restrictions for some nationalities.
