Grassy Point, Corpus Christi, TX, US. Forecast 22 mph, we got several hours of 32 mph with gusts to 40. More southerly than usual increased the water level significantly and created nastier chop. RB 5.6 & Isonic W54 was too big for me, mostly did survival sailing, seeing how slow I could go. Eventually found a 200 m long strip of flat water behind Pita Island, but did only 2 runs there since I was not sure that Nina (who rigged down from 3.7 to 3.4 and still was overpowered) could see me there. Would have been good for another know or two for 2 seconds. Not sure about 10 seconds - the water is reasonably flat after the speed strip, but there's a sandbar under water that would need some checking first - may just be deep enough, or may not be.

The GW-60 played a little trick on me in one run: it jumped ahead suddenly by 13 seconds, and corrected itself about 9 minutes later. I might not have noticed if GPSAR had not given me a 30 knot alpha in this region! This happened to be right where I had my fastest mile, and GPSAR calculated it at 27.9 knots for the GW-60. The USB dongle and GPSLogit, which both recorded the region without problems, had this region at 26.85 and 26.88 knots. GPSResults excludes it from analysis due to the "missing points", and ka72.com seems to do the same.
