What is the flash character and range of a blue flashing light?

• A. Flashes 30-50 times per minute, 1 mile range
• B. Flashes 57-70 times per minute, 2 miles range
• C. Flashes continuously, 3 miles range
• D. Flashes 60-75 times per minute, 1.5 miles range

Answer: (B)

The blue flashing light as defined in the COLREGs serves a specific purpose and adheres to particular characteristics to ensure proper identification at sea. The correct answer indicates that a blue flashing light flashes 57 to 70 times per minute and has a range of 2 miles. These characteristics are crucial because they help distinguish certain types of vessels, such as those engaged in law enforcement or search and rescue operations, from other maritime traffic. The specified flash rate falls within the recognized parameters for a blue light, making it easily identifiable to other vessels at a considerable distance. A range of 2 miles is significant in the context of vessel navigation and safety. It allows for adequate time for other mariners to recognize and respond appropriately to the presence of the vessel using the blue flashing light. Understanding these specifications is essential for interpreting lights correctly while navigating, ensuring compliance with maritime regulations, and promoting safety on the water.
