Baard is correct ... 11 public Moorings recently added. I confirmed this personally during my trip of last month. Details here ... https://www.bvimariner.com/anchorages/other-anchorages/guana-island-white-bay/

Orange moorings at Northern side of Bay are private. At least one of the public mooring balls was labelled "Do not use in high winds or waves, 35' max.” (per comment at above link). The ball we used did not have such warning. Fee was collected by Guana Island Resort. Beautiful, quiet anchorage when conditions are appropriate.
