Arrived about 4pm to very light sw winds. Opted to take the F161 and 9m. Spent the next two hours nicely powered and getting peaks around 28/29k. Around 6.30pm, the wind plucked up a lot, I was at south end of the lake when the wind picked up so did one pair tack run feeling fully maxed. 31k 10 second, thought ah, four more of those and I can improve my previous formula ranking (29k). I think this gets me back into the top 10 all time formula ranking. So not an epic day, but got a nice small result. Was fun:)
