The posted beach signage at Culebrita and Luis Pena is consistent with the above OPERATIONAL PROCEDURES - stay off the beach from sunset to sunrise. The only boats that might operate in the intertidal zone are dinghies and the local day trippers that may pull their boat to the beach in calm conditions.

I noticed that the vast majority of mooring balls throughout Culebra and surrounding waters look to be marked DPNR - DAY USE ONLY. The moorings are much more substantially constructed than the BVI NPS day moorings. l'll admit that I've overnighted on these DPNR moorings - to Jay's point, it seemed counter-productive to the protection of the seafloor to drop an anchor and chain at sunset.
