a hypothetical ethics question.

OK I have a hypothetical ethics question.
Picture an average day of surfing with 4ft waves. Surfer Bob is paddling out. Surfer Neal is about six feet in front and about three feet to the side of Bob. Neal decides to take a wave and runs over Bob. Now Bob’s board is needs a $100 repair. Who should fork out the cash to fix the board?
