I am all in, but in the original post it was stated that the sailor did not know that the boat touched the mark. This is key: The expectation of the behavior of the skipper will be different if he knows that he hit the mark vs not knowing.

Thus, a sidebar chide might be in order. "hey Bro, did you know that you hit A mark in the last leg of the 3rd race, you now owe me a beer to exonerate your self"
