The pleasure boaters will get the odd fish jumping in the boat when idling around but I don't foresee anyone getting taken out by a fish at speed unless they are following another boat closely. I have shot them with a bow for several years now both on the lakes and below the dams. When they get spooked from above in deeper water they generally go down instead of jumping. 6 feet or so or less is when they will start jumping out of the water from surface commotion, just from what I have seen. They are usually well behind the boat when they jump as well unless you are just putting around.

The sheer biomass that they are eating per day has to be wreaking havoc on the food chain. There are 2 types of the carp, the silver and the bighead. The silvers are the ones that jump. The bigheads get up well in excess of 50 pounds where the biggest silver I have seen is probably 20. But the thing to remember is that there are literal millions of them out there now. How much biomass does just one school of 50+ lb bigheads consume per day? Take that amount and multiply it exponentially.
