Two duck hunters are seated back-to-back in a boat. How large is the zone-of-fire for each hunter?

In this scenario, when two duck hunters are seated back-to-back in a boat, each hunter's zone-of-fire is determined by the area around them in which they can safely shoot without putting themselves or their partner at risk. A zone-of-fire of 180 degrees means that each hunter is responsible for covering a semicircular area in front of them, extending out from their position.

Given that they are back-to-back, each hunter can safely shoot directly in front of them to the sides, covering a total angle of 180 degrees. This configuration ensures that they avoid shooting toward one another, which is critical for maintaining safety.

Having a zone-of-fire larger than 180 degrees would increase the risk of unsafe shooting practices. A zone-of-fire that encompasses 360 degrees would mean that a hunter could potentially shoot in every direction, which is unsafe, especially in close quarters like a boat. Thus, 180 degrees is the appropriate and safe zone-of-fire for each hunter in this setting.
