FWIW we were at Lake Wylie NC a month ago for a Mastercraft reunion.
One of our group was heading home around 10 pm at wake speed because they were unfamiliar with the lake. They were having trouble with their bow light, but the stern was functioning.
They were in a 20' boat and got T boned by a bass boat estimated to be going 45 mph.
I can't imagine going that fast without a clear view of what is approaching. Though my friend's bow light was possibly out, they could have just as well been anchoring and have been hit.
Somehow none of the 9 involved were hurt. Just shaken up. And a couple of totaled boats.
