I chartered through Dream Yachts in Marigot a couple years ago. The downside was that the boats are inside the lagoon
and the Marigot bridge openings are more sparse than the Dutch side. We couldn't get boat paperwork done until the evening (after customs
had left) and then couldn't clear customs
in the morning soon enough to get to the 9AM bridge opening. Next bridge opening was early afternoon. We were headed to St Barts so ended up going across the lagoon
and out the Dutch side. That was right before they finished the new bridge across the lagoon so we only had the one bridge to contend with. If you charter out of Marigot, make sure you plan ahead for customs/bridge opening.
The Dream Yachts boat was OK but not quite up to Sunsail/Moorings level. It was less expensive so we got what we paid for. We had no issues with the boat. I had chartered a couple years earlier with Sunsail out of Oyster
Pond and if I were to do it again, I would opt for Sunsail/Moorings in Oyster
