Lots of holes in the geofencing discussion. Many boats do not have AIS. There are not enough AIS ground stations to track all areas and MarineTraffic.com requires a subscription to access satellite tracks.

As far as an app-based reservation system for the VIPCA moorings, remote payment makes sense. I expect the VIPCA moorings in Coral Bay will be popular. I'd be happier if the NPS added an app or online payment system. First come first served works better than reservations. Trying to chase someone off of your reserved mooring is a recipe for conflict.

We don't see DPNR enforcement boats on the south shore of St. John and Coral Bay unless the East End homeowners call DPNR; for some reason they get service. Saltwell Bottom beach in Hansen Bay, access through private land for a fee, put out its own swim buoys without a permit.
