One of the most vivid was a guy with a sailboat that attempted to drive under a line with the mast up ! It was a 7,200 line and the arc initiated when the mast was over a foot away..... You can believe me or choose not to..... your call....but it happened. I can't argue with the theoretical calculations, but I can guarantee that power lines are considerably more treacherous (in regard to arcing) than is to be expected.
I would choose not to believe you. Or at least choose not to believe what you think you know. The more likely explanation is that yes, probably he had about a one foot clearance, but water is rarely perfectly still especially in areas where a sailboat is going to be. A one foot peak high wave on the water would easily cause the clearance distance to become zero. No need for magic or violation on physical laws here!
