This is a photo of a guy in Maui (I think his name is Hugo, not 100% sure), he would be 65 in the shade and he still rips hard.
If being a windsurfer at our age (being very wide in range here)is a mid life crisis this guys never got pass his and no way do I intend to either.
He was cranking on a 6.2 RS on this day when I was being blasted on a 5.8 wave sail.
He rips out past the reef, turns and heads back, if he makes the in bound gybe (jibe) he goes for another run if not he picks his kit up, puts it on the beach and has a rest.
In a little while he picks up his kit and does it all again, he has some very cunning rigging tips to.
No mid life crisis just a great time at all ages. This guy in inspirational.
