What is a common cause of hunting-related incidents involving watercraft?

The correct choice emphasizes the importance of personal flotation devices (PFDs) in preventing hunting-related incidents involving watercraft. Many incidents occur when hunters fail to wear a PFD while on the water, increasing the risk of drowning in case of an accident. Watercraft such as boats or canoes can be unpredictable, and a sudden incident can lead to capsizing or falling overboard. Wearing a properly fitted personal flotation device significantly enhances safety and survival chances.

In addition to this, wearing bright colors like orange clothing and following firearm safety rules are critical for visibility and safe handling of firearms during hunting. While these practices contribute to overall safety, they do not directly address the specific risks associated with watercraft. Crossing fences improperly, although it can be dangerous in itself, is not related to watercraft accidents. Hence, the failure to wear a PFD is a primary contributor to incidents in this context.
