My coaches get after me about not seeing the next buoy out in front of the boat as I finish the turn (cures head tipping too!), once turned, the buoy is 'behind' the boat- I (try to) look at a specific point on the boat- pylon, lift eye, near/far corner, whatever works, until I have croseed centerline. (Aim small, concentrate...)
But mostly, when the line goes tight, my mind goes blank.
There is hope though, I read that Pavlov's dogs did not salivate at the bell when they were not hungry- whatever that means!
