Hey Jase, knee is great mate, 95% now I reckon and absolutely no issues sailing at all. I just know that my duck waddling days are over.
The hat is just an O'Neill I picked up from Sam, it does have a stiff front section designed to stay solid at speed.....BUT only up to about 28 odd knots and then she slides backward on the scone and becomes useless. It was rigourously tested at Sandy point this year

You back in Oz yet or still swanning around the Greek isles?
