Recreational enthusiasts have suffered serious injuries when they or their equipment came too close to overhead power lines.
Pilots, for example, must ensure that they look for overhead power lines when flying near ground level because they can be difficult to see in certain lighting conditions.
Sailboat masts can be tall, and can contact overhead power lines (yes, they exist over waterways in some locations).
Acting as “pilot in command” carries certain obligations, including safely operating the craft at all times.
