We were there 2 years ago around the same time of the year. At that time there were only 2 mooring balls and one was questionable. They claimed to be replacing them soon so sounds like that happened.
We loved the island and the friendly people. To get to one of the little towns from the harbor is almost straight up a hill. Tried to rent a car but local advice
was to just hitch hike...it's the first time anyone's ever stopped to give me ride and we ended up at their young kids
Also did a couple of good dives with one of the dive shops in the harbor.
Now to the downside...
you need to grab a ball by the main harbor to clear in. The seas were so rough there that it's the only place we ever put on life jackets to get into the dinghy
and were afraid we won't be able to get back on the boat
. It was rough.
The anchorage is probably a good 2-3 miles around the corner and it was also very bouncy. There was no shot in hell of landing anywhere near the ladder when we were there.
Traversing from the anchorage to the harbor is against a very strong current
and as you guessed it, very rough.
We only stayed 3 days because the rough water
wore us out. I would go back in a second maybe during the summer or we'll fly/ferry for SXM in next time.
