#6) When the autopilot is on, so is the harness and tether.
The strangest thing happened. When I was about 13 years old, we were living on a 56' schooner in Clearwater. All alone on the boat at the dock, I was down below when the boat suddenly heeled over at about 10 degrees or so. It was a nice day, the weather was calm. Later, the people said it was like watching dominoes as the whole dock of boats leaned over in turn. It came out of nowhere and no one had an explanation for it. No follow up phenomenon either. Imagine something like that happening when sitting on the edge of the gunnels with a fishing pole. In you go.
