Training Results
Welcome to the most comprehensive COLREGs Lights and Shapes Trainer available online. Whether you are a cadet preparing for your first OOW (Officer of the Watch) oral exam or a seasoned Master Mariner refreshing your knowledge of the Rules of the Road, our simulator is designed to build absolute confidence in night navigation.
Why Practice with our COLREGs Simulator?
Navigating at night or in restricted visibility is one of the most challenging aspects of seamanship. Correctly identifying a vessel’s type, size, and aspect through its navigation lights is critical for avoiding collisions. Our trainer provides:
-
44+ Realistic Scenarios: From standard power-driven vessels to complex towing operations and vessels restricted in their ability to maneuver (RAM).
-
IMO-Compliant Terminology: All questions and answers use standard Maritime English as defined by the International Maritime Organization.
-
Realistic Light Simulation: Our proprietary engine simulates “bloom” and flicker effects to mimic real-world visual conditions.
-
Mobile-Optimized Experience: Practice on the go, whether you’re in the classroom or in your bunk at sea.
