I think decrepit is in his low 70's now, although he does not look a day older than 60!

I very fit man and still keen as'! An inspiration to many of us irrespective of his age.

I didn't officially crack 40 knots until I was 53, in 2004. I say 'officially' because that is when we had a way to actually know due to using the first GPS devices. I might have got close a few times before that but have no way of knowing.
I got to 44 at 55 in about 2006. There is some symmetry in that.

All I want now is to do another PB while I still can hold a boom. They are getting a lot harder to come by...... It will take a very special day and place!
All I can recommend is that you widen your travels to try and be in the right place at the right time. (To me that is exactly what speed sailing is all about). I am extremely fortunate to have been at Sandy Point though its golden years. It's not as consistently good now, but there is no doubt it can still produce PB conditions for me when everything comes together just right. In the meantime, travelling to the many other great speed spots in Australia has enabled me to get PB's in other categories, have fantastic fun doing it and meet some of the best people in the world.
Hook in and hold on!
