This is a summer session in open water east winds, water tends to be smoother the wind and current were in same direction. I did not measure the current that day, typical current is around 1.5 to 2.0 knots.
I was medium powered, a couple times a little more than that, 7.0 would have been better, but sail hadling easy with 6.3.
It would be nice to see more open water times here and other Gorge locations
