Were there trophys or other awards involved and did he take 1st place? I would think if that was the case, the rest of the fleet should protest him. Where did he finish over all? If there were no awards, what does it matter? Since you are new to there, I would mention it to some of the other regulars and see if this is acceptable to them, and then as Scooby says, just ignor him. If instead he is up on the podium claiming 1,2 or 3rd place...you should menion it to the committee boat people.
