This probably won't last. Though not my kind of beach experience, White Bay has become a drive up day boats destination..many from USVI but also BVI. Unlike Spring Bay where the same sort of buoy line keeps dinghys out, there is an economic consequence to this action. I am unsure of the length of White Bay that the buoy line goes ..if it simply moves the anchored day boats and keep from congregating in front of Soggy Dollar area, will work. If it's a small "safe area" will likely stay. If is restrictive for most of that side of white bay and keeps day boats and their passengers from the lines at Soggy Dollar, there will likely be some changes. When it's not about the $$, it will become so quickly.
During the day for a long time White Bay has become a place to watch the parade of people, not a pristine beach experience.
