Hell I would be chasing them around the lake with my boat trying to see if I could hit them. Like Dauphin Tag.
Just look at how many boat's each summer hit each other on our rivers and lakes and add a semi submerged things that no one will see unless it is on top and running full out. Last year I saw 3 Jet Ski's get hit by big boats and hell I am never in the US. The will start demanding boat free areas so they can play in safety.
