Windsurfer here. I was on blue board, blue sail ...blue rashie (it's a coincidence, honestly!)
I was a little upwind nearing the gybe point over at Crab Island. Then I had a brain fart.
It looked like I'd have enough room to gybe
if I cranked a hard turn, and
if you continued at your present speed and direction. I was wrong, and I realised about half way through the turn. Nearly crashed into you, hard.
Apologies.
