It's OK but I am not happy

Well my 'thinking' didn't amount to much as we did very badly on Wednesday. We went to the wrong side. Very shifty conditions and I didn't know where the wind was coming from. Once we chose a side we kept with it even when it was no longer favoured. We overstood the layline to the windward mark on the last windward leg. Our windward douces went well (given our level of experience!). Generally a very bad race. We could improve on technique, but I think the big problem was that we were unwilling to challenge our perceptions.
