We visited in May 2014. The harbormaster was not present on a weekend. VHF calls on ch. 9 and 16 were not answered. Local boats advised against attempting to enter at low tide with the 2m draft and I could see why. However, we were told the ground is soft sand, not rocks. Dredging is still ongoing and from what it looks like must continue to go on eternally.

We spent a pleasant night moored to the outside of the breakwater-float with electricity and water. An immigration/police officer was present and supplied us with an access card but told us there was no way to pay for the marina on a weekend.
The tell-tale signs of bad swell were visible around the marina: local boats tied up with a spiderweb of mooring lines, chafed lines, ruptured shock absorbers, blown fenders.
