The idea is to fuse data from AIS and radar to make better, faster collision‑avoidance decisions. Relying on AIS data to override radar means you treat the vessel’s own transmitted information as the primary source for identifying and assessing its movement. AIS provides the target’s identity and its declared position, speed, and course, which helps you resolve which contact you’re tracking and anticipate where it will be. If there’s a discrepancy between what AIS reports and what radar shows, prioritizing the AIS data helps reduce ambiguity and supports a decisive action plan based on information the other vessel has willingly broadcast. At the same time, keep radar in play as a safety net—to catch targets not on AIS or to verify AIS information—but let AIS drive the principal avoidance decisions when there’s a conflict.
