We started a tad frantically but pulled away a bit, then they caught a painful looking crab, and we were told there was going to have to be a restart because this had occurred within the first 100 m. Baffling...
We were then told that since no contact had actually occurred, this was a mistake and we had actually won, unless we wanted to race anyway... which we did, seeing as we were going to have to get to the other end of the course somehow.
They stuck with us for a little while off the (re)start, perhaps a bit wound up by our insistence that we didn't want a headstart, but before long we had pulled away and won comfortably.
(jo)
