Parallel Index Technique on Marine Radar | A Must-Know Skill for Navigators

Parallel Indexing is one of the most essential radar techniques used by professional navigators during channel transit, coastal passage, restricted visibility, and confined water navigation. In this instructional video, learn how to properly use the radar’s Parallel Index function to maintain a safe distance from hazards, monitor vessel movement, and improve navigational safety. This technique allows bridge officers to continuously monitor the ship’s position relative to coastlines, shoals, breakwaters, and channel boundaries — making it an invaluable tool during channelling operations and high-risk navigational situations. Understanding and applying Parallel Indexing correctly enhances situational awareness, supports effective bridge watchkeeping, and strengthens safe navigation practices at sea.
