YAK Fishing Question

[Billfish715]

I know lots of fishermen have taken to kayak fishing in salt water. There is even a cable show about the exotic places where people fish with them. But......is there anything else but common sense to govern how yaks are used? On our way back to Manasquan Inlet yesterday in the fog, our 38 footer almost ran over a yaker very close to the inlet. He never showed on the radar even though we had it dialed in to 1/2 mile. The guy had no radar deflector or flag. Fortunately, we saw him and we were not going fast, but still, it was fortunate he was off our port side about 30 yards when we spotted him. Visibility in front of the inlet was about 100 yds. at the time. On another occasion, while fishing off Sandy Hook a few years back in my friend's center console, we towed a yaker in distress back to shore from over a mile out. He couldn't paddle into the strong NW wind. This guy wasn't even wearing a PFD. What goes with yakers?
