There are moorings there, just east of plane wreck, but can't tell if they are day only or overnight. No markings on them, it's just that they are situated around snorkeling sites so a little unclear.

Mooring balls are all in place and useable. I think different balls managed by different owners. I think hopetown inn marina manages some.

I can't answer your question but are you part of the Bahamas cruisers Facebook page? That question is asked on that site all the time.
