I wonder what the excuse is for this. If its daylight I don't see one. Night time in unfamiliar water...maybe. But he should have been going slow with a spot light looking for objects like this. Looking at the impact damage, I'd say he was well above no wake.
Early last year the Coast Guard in Buffalo erected new work lamps on the property. About 8 poles of 2 LED's lamps each. So incredibly bright. When coming in from the Niagara River you have to pass two large breakwalls. On the north side of these breakwalls are flashing white markers. Before the CG lights were installed, I could see them. Now, with the LED replacements on CG property, the breakwall lights are obliviated and cannot be seen let alone the breakwall. I sent them a letter a month ago about it. Haven't received a reply, not that I expect it.
