You've nailed it with the essence that is a Lake Burley Griffin easterly session. It's the camaraderie, the common purpose, the anticipation, the actual physical and mental challenge of the blow, and the joyous and smug aftermath.
When Jase was setting up his "Canberra Windsurfers" website, I started on a parody of "The Man from Snowy River", with the intention of contributing it to his site. Shameless plagiarism of Paterson's great work. It started like this

:-
There was movement at Blue Gum Point, for the word had passed around, that the Easterly would likely blow that day,
It was due at six or seven, and at maybe twenty knots, so all the cracks had gathered to the fray.
All the tried and noted sailors, from Canberra's suburbs near and far, had mustered at the Point that afternoon,
And were rigging, in anticipation, for a full-on sailing session. They knew the wind was gonna come "real soon". And so it went. It didn't get any better.
I tried working the personalities from the original into this tripe. "
Harrison, the old man with his hair as white as snow" could only be yours truly. Clancy - "
No better horseman ever held the reins" would be my mentor, "
no better sailor ever held a boom".
"
And one was there, a stripling on a small and weedy beast" would become "
And one was there, a stripling on a small wave-sailing board", which could only equate to Akim.
And, indeed, it's "Clancy" and "the stripling" that show everybody how it's done, both in the original poem and on the lake.
Happy days, indeed!
