Taking Horton’s zip tie idea to the next level, it seems like it would be relatively easy to put a laser at each end of the lake pointing at each other down the center of the lake. Sensors on the front of the boat would monitor the position that the laser hits the boat. A simple series of LED lights (green in the middle, yellow to each side, and red to the far right and left) could be put in above the steering wheel that would show the driver which way they are off center and to what extent. This would give the driver constant feedback on position instead of them having to wait for the boat guides. If the position lights are recorded for each pass, it might be used to give quicker feedback to the judges for deciding on re-rides.
