Which zone is described as the outermost area where all contacts are made?

The Assessment Zone is considered the outermost area where all contacts are made because it serves as the first point at which a coxswain assesses other vessels and any potential threats. This zone is crucial for gathering information and understanding the situation before any further actions are taken. It allows the coxswain to evaluate conditions such as the intentions of nearby vessels, weather, and navigational hazards, ensuring a safe and informed response.

In operational contexts, this zone functions as a defining space that precedes more direct interactions or engagements, making it a foundational element in navigation safety and decision-making processes. The Assessment Zone provides vital situational awareness, which is essential for planning and executing effective maneuvers in more critical zones that follow.
