Cyclone Hamish sure gave us some great sailing on the Sunday at Yeppoon.
when I had finished for the day my GPS (Forerunner 301) showed a max speed of 81.5 kph, but when I got home and downloaded the data it gave me a 106 kph maximum! This isn't the first time it has happened, it also occured in Speed week in 2007. I can't remember what it showed on the day but at home I discovered 91kph, and this was a blatant all out speed attempt so I am positive the data is fine. I have since found that my GPS smoothing has been set to "most" which would remove any quick peaks. I had to be really sure about this before posting and had data double checked on another site. Satellite reception was rated "excellent". Lots of looking at the data and other high speed runs to make sure. But I am confident this is real!!!

Back to Yeppoon, the speed was attained over a 300m acceleration/deceleration phase, lasting 5 seconds in the acceleration and 13s in the deceleration phase. There was a 2 second period when the speed is above 100kph.
It was late in the day and remeber a gust and I thought just keep it flat. So all 105 odd kgs leaned out and we stayed on all wheels. I looked over later at the GPS and it still showed the speed from earlier in the day. I was using a 2m sail with fibreglass mast No 2 all way. When sailing the beach earlier with Ben who was using a 3m, before the event was cancelled, his comment was that when a puff of wind came through I just accelerated away.
