Last fall I planned my dive trip from Oregon to Jupiter/WPB specifically around the tide tables so I could dive the BHB as much as possible. This was my first time to BHB. My first dive was a boat night dive and there were about 8 in the group. As we were going to the area of the menacing fishermen, I felt a tug and a resistance to my flag. Some drunken a***hole fisherman had hooked my flag and was tugging it pretty hard, forcing me to come to the surface. At that time, I didn't know what was happening, but I thought perhaps I got into some entanglement with other divers' flag lines. When I surfaced, I looked up to see the fisherman laughing. It was the fellow divers who then told me that this is what they do to divers. If I had known of this danger ahead of time, I would have been more prepared to respond appropriately in self defense. This was an intentional assault to try to harm me and I was pissed. I've never heard of such behavior towards divers.
IMO, we have the right to defend ourselves from dangerous assaults such as this, and we should fight back. In that moment, I would have grabbed his line and yanked on it and perhaps he would have fallen into the water. He deserved it. Or maybe even cut the line. Perhaps if you respond more aggressively if this happens to you, they may get the message and stop messing with the divers. Perhaps you could have one of your buddies as a lookout topside on the bridge and confront the morons doing it in the act, film it, call the cops, whatever it takes.
I feel bad for you locals who have to put up with this. I'm a diver who brings tourism dollars to Florida, so I'll drop an e-mail to the councilwoman.
