Thanks Ducati.
We had a nice wind today, so your link looks a bit more respectable now.
Just another thought, I know a lot of sailors my age and over, ( mainly couples as well), you could probably call them the grey nomad windsurf division, come from all over Aus, to be in our NW over spring. We bump into them on our yearly, start to the season, excursion.
Most of them are into waves, gives some of the first time Euros a surprise, they're not used to seeing elderly ladies and gents, jumping waves and having fun in the surf.
