Rule 30.3 requires disqualification without reservation if the race is sailed in that start; it is sufficient for the boat to be in the triangle, regardless of cause.  To reinstate her would require an award of redress for which none of the options in Rule 62 applies.

Warren, fair point on redress. But I'm not sure I see the 30.3 disqualification as irrevocable, it seems to me on valid protest the boat could be exonerated under 64.1(a).  That seems like a more fair result to me. 

However the boat still has an obligation to start properly, and being forced OCS doesn't prevent her from doing so. So in David's scenario the boat might be exonerated for breaking rule 30.1 and have the UFD vacated but would still be scored OCS. 

See Case 140

Thank you lady and gents.
Case 140 clears up the question of my post. But the situation in a restarted Black flagged race seems very harsh on the ROW boat and super lenient on the offending boat.

Dura lex sed lex!

The law is harsh but it is the law!

I doubt we would find many U- or black-flagged OCS boats that would not claim they were pushed over the line.
