We had some discussions this past weekend on this event.
Just prior to the start at a packed comittee boat. Just as the gun is fired the boat dead astern taps a boat directly in front of them. Seems straight forward, the boat from astern is wrong, but, the boat from astern states other boats were barging in on the line to windward thus not allowing them to head up to avoid the contact. The boat astern hails one of the barging vessels and the barging vessel agrees and does a penalty turn. So the question is. If a boat inflicks a faul on your cat, thus causing you to foul another cat, do you have to do a penalty turn?
