What is the initial search area radius for a Person In Water scenario?

The initial search area radius for a Person In Water (PIW) scenario is established based on various factors, including typical drift rates, environmental conditions, and the time elapsed since the individual went overboard. In standard practice, a radius of 6 nautical miles is typically recommended because it accounts for the possible distance a person may drift due to water currents, wind, and other environmental influences during the timeframe before search operations can commence.

This larger radius provides a higher probability of locating the person more quickly and efficiently, as it covers a broader area that they may have drifted into. In contrast, smaller radii would not encompass potentially critical regions, making it less likely to successfully locate the person in distress. Therefore, the establishment of a 6 NM radius in this scenario helps ensure a thorough and effective search effort.
