I blew a few tacks myself. I rationalized it thusly:
(Reminder, I was sailing one up)
With the early big winds, I was a coward and crossing under too early. I didn't want to have to climb uphill.
I have driven a Nacra5.2 for 10 years. The longer sterns and therefore tiller arms respond differently from the short sterned Taipan. So, more than once, I just pulled the rudders over too far as I was crossing over.
Being a sloop guy, the boat had to remind me a few times to bear off further and ease off more before getting into Rock and Roll mode.
