I have neighbors that just mark them with anchored bleach bottles. They have for years and appears to not be an issue with the "Powers-that-be".
I have rocks also. I know where they are. Frequently boats that come way too close to shore get rewarded with out-drive damage. Sea Tow has made some money off those rocks. I smile and wrestle with a twang of guilt...Not much though!
