Way too much wind. I started with 5.8 and went to 5.3 which was also difficult and later impossible to hold.
I had to go to work afterwards so left early. I wish I had more time because looking at horst after 15:00 sailing would have been easier and faster.
Simmer 3XS 80 was perfect! Hope to sail it more soon to see its potential. Totally different board than X-Fire 80 (both AV shape but Simmer is Mono concave and X-Fire has V), but both very nice :-).
