If you look at Gordon's exif data on the Flickr page, you'll see his pic was taken on April Fool's Day last year, 2012.
I was going to say Gordon, you have your days messed up, his pic must have been taken on the Friday, as there was specifically a demo day in Queenstown Bay for the tourists and others that day. My pic was taken on the Sunday, the second day of competition in Frankton Arm. AFAIK there were no racing boats in Queenstown Bay over the weekend. Also, the Sunday was alternating between cloudy/rainy/sunny.
Gordon's pic shows a perfect day in Queenstown, which is alarmingly common, just not on that day.
