With reference to the buoys being put out manually…. the few occasions that I have helped Andrew he has made me aware of the yellow marker that is positioned on the outer edge of the worktop that we put our boats on.
When Andrew goes into the water he looks over to the pit area were he can see the marker and then manually position the buoys on the turn area to be in line with this marker.
Maybe Andrew knows the exact measurement from the bank ?
From my own requirements I have been more than happy with the positioning of the buoys BUT as you say, I agree that we should try to come in line with the Naviga measurements so that we can compare our laps/time with the competitors abroad.
