I assume you mean Sint Maarten - the Dutch side. Horizon has a limited fleet in Simpson Lagoon
but Moorings/Sunsail has about 50 boats in Oyster
Pond. The exit from Oyster Pond looks scary but it is 30 feet deep in the channel. They have added a customs
office in their facility that makes clearing in and out easy. Plan on loosing most of your first day to provisioning
and boat orientation and having a short day at the end as most flights leave for the US by 3PM. You can stay at Captain
after your charter if you need to. A new grocery is to be added this Fall at the facility to allow for self-provisioning or you can take a taxis to Grande Mache which is an American style store that even sells booze at duty free prices. I have kept my boat in the pond for the last two Winters and am quite familiar with where to go and what to do should you need suggestions.
