Can anyone tell me if there are definitive regulations with respect to how close a boat can approach a diver/freedivers surface marker buoy (SMB)? I was fishing off Beer, Devon about 200m off beach this weekend with an orange SMB with Blue/white flag. Whilst surfacing from a dive I realised that some t**t in a speedboat was about to decapitate me even though I surfaced right next to my bouy. He realised that he had very nearly hit me and switched off his engines. There followed a very heated exchange with him claiming that I shouldn't be so far out from shore and me telling him that boats are supposed to respect a diver-down bouy and keep distance. I was so mad I nearly shot the idiot with my Omer Excalibur and he was eventually persuaded by his mates on the boat to clear off. Was I in the right and if so where can I find the appropriate regulations??? I'll laminate these and stick them on my buoy!!!!
