How wide is the initial search area for a PIW incident?

The width of the initial search area for a Person In Water (PIW) incident is defined as 6 nautical miles. This distance is based on established protocols that take into consideration various factors, including the average drift rate of a person in the water, prevailing environmental conditions, and the time elapsed since the individual entered the water.

The 6 nautical mile width is deemed appropriate to account for the uncertainties and variables that can affect the search area, such as current patterns and wind. This allows for a thorough initial search that maximizes the chances of locating the person quickly. In contrast, the other options present narrower distances that may not capture the full drift potential, thus potentially reducing the effectiveness of the search effort. Overall, the 6 nautical mile width is a standard reference point utilized in maritime search and rescue operations.
