Thanks, I'll take a look.

Anyone noticing or knowing about AIS fixed obstructions/bouys/etc. being
transmitted from shore stations in their area, please let us all know what
you know...thanks, too!

"AIS (Automatic Identification System)

The International Maritime Organization has ruled that all vessels of
300 gross tons or greater and all passenger vessels must carry AIS
transponders. These transponders broadcast their own AIS data and
receive it from other vessels. Information such as the vessel
identity (MMSI, vessel name and callsign), position, rate of turn,
course, speed, destination, and cargo is continuously broadcast over
VHF frequencies and displayed on dedicated or integrated navigation
systems. Though these active systems are expensive, there are low
cost, receive only units available that provide, for the small boat
owner, a display of much greater use than radar for these 'big boys'."
