The day's forecast called for much lighter winds than this! And given that it was blowing right up the valley, there were big (for here) rolling swells, even in the lulls. I was over-powered on my 8.1, so I went back home and got my 7.0. Made one jibe dry, shown here. (It looks fast [which is partly why it's fun], but my top speed here was just 17.1 mph.)
