In fairness, the boat owner should be compensated for damage to his boat and any property damage to his home and grounds. But I'll bet the boat would get above market value at auction, as is.
I agree... that man is a hero. He tipped off the police and/or FBI as soon as he saw the perp lying in his boat bleeding.
Greta Van Sustern had a pretty long interview with the man's stepson last night (last name is Duffy). It took them a good 30-40 minutes to get through to any of the authorities with their very important "tip". He said it was extremely frustrating... they kept getting busy signals, etc.
If the perp wasn't so weak, I have no doubt he would have escaped from the boat long before anyone got to him.
