I was able to find out that the Vectorworks/Bimare XJs finished in 6th, 9th and 10th with respectively Woody Coope, Ian Lindhal and Peter Cogan.
I am not saying you are wrong, however, Ian Lindahl purchased an A2 from me this summer after leaving Vectorworks. Ian's A2 has a Hall Mast (purchased from Nacra) and an Ullman (Glaser, when he still was associated with Ullman) mainsail. It would surprise me if Ian sailed an XJ at the NA's.
