Another Ratings Change??

We were notified by YRA yesterday that there was an error on our PHRF certificate that they had just noticed and corrected, resulting in a lower downwind rating.  This is the third downwind rating we have had this year.  Our regular rating is 81.  Our original downwind rating was 39.  Then we requested a change as we would carry only symmetrical spinnakers.  We expected 3 seconds for that but our new downwind rating came in at 88.  Believe me I called to make sure that wasn't a mistake and I was assured it was correct.  Yesterday we received notice that one of our spinnaker measurements had been reported in meters and they had converted it to feet and recalculated our downwind rating as 63.   It will probably change again as I sent the new certificate to our sail maker to check the converted measurement and it was listed as a foot larger than it actually is.  We shall see where we land but it looks like we will still start Tuesday at 12:15 as there are a couple of boats with lower ratings than 63.

Edit: the sail measurement correction did not change the new rating of 63 so now we are discussing potentially having the boat weighed and trying to get another new rating before the race.  We have had several people tell us our boat weighs more than what J boat says as we have a huge s/s radar arch.  Two people from the PHRF committee said that the weight makes a "significant difference" in the downwind rating.  I just talked to the official measurer and he guestimated it could be 5000 heavier (that is 25%) than the "official weight" and he has never even SEEN the boat or its arch.  Why couldn't this have happened BEFORE the last minute???  LOL.  Gotta love this yachting stuff.
