Its not an equivalent safety situation but we had a case this summer where a chap anchored his boat in an estuary and was sat with wife in the cockpit when a drone appeared and hovered 20 ft away no doubt with the camera going and people on shore watching. He could see the operator and his mate, waved and shouted at them but got two fingers in reply. Went ashore and the respnse he got was very aggressive along the "i'll do whatever |I want line"
What is needed is a laser type "gun" emitting on the operating frequency of the radio coms used. Or an air rifle.
Drone jammers exist - one even looks like a rifle that you can point at a drone and bring it down. They're effective at around 100 yards - but rather expensive.
