To whoever (10m blue kite with orange struts) retrieved my board and brought it downwind and saved me ~10hrs of body dragging...thanks! I stuffed up the "last jump" of the session and crashed and tumbled the kite and spend ages to relaunch and was close to the life saving club until I had the situation under control. Learning for today: Don't go out in Brighton if the wind is dead northerly, it might end badly...but what an awesome session!
