Allow, no penalty. Why? Why not? They can't continue without them.
I guess your question can't be answered without understanding why the NoR required the declaration in the first place.
I would imagine it is to keep people from deviating from the design of the rudders and possibly swapping them during the race for different conditions...but does that really matter? If the rule says it, they broke the rule. I think they should suffer some sort of penalty after the replacement rudders have been assessed to ensure legality. If they're illegal, the penalty should be considerably tuffer.
