This is also from Elon 2009.
I was involved in the incident and made a ham sandwich of the rounding, which is one reason it has taken me so long to write this post after promising Frank Angel that I would.
If an inside boat with mark room protests the outside boat for not giving enough room and forcing her to hit the mark, and the outside boat does a turn (or later loses a protest) then the inside boat is exonerated for hitting the mark by rule 64.1(c).
64 DECISIONS
64.1 Penalties and Exoneration
(a) When the protest committee decides that a boat that is a party to a protest hearing has broken a rule, it shall disqualify her unless some other penalty applies. A penalty shall be
imposed whether or not the applicable rule was mentioned in the protest.
(b) If a boat has taken an applicable penalty, rule 64.1(a) does not apply to her unless the penalty for a rule she broke is a disqualification that is not excludable from her series score.
(c) When as a consequence of breaking a rule a boat has compelled another boat to break a rule, rule 64.1(a) does not apply to the other boat and she shall be exonerated.
(d) If a boat has broken a rule when not racing, her penalty shall apply to the race sailed nearest in time to that of the incident.
In a similar but different case, if the inside boat is forced to miss the mark by the outside boat, she still has to come around again and round it.
