How many flashes per minute does a special flashing light have in inland waters?

A special flashing light used in inland waters is required to flash at a rate of 50 to 70 flashes per minute. This specification ensures that the light is sufficiently visible and can be distinguished from other types of navigation lights. The use of a specific flashing frequency helps to convey important information to other vessels, contributing to safety on the water.

The range of 50 to 70 flashes per minute has been established by regulations to provide consistency and clarity for mariners. It distinguishes a special flashing light from other navigational aids, helping to communicate specific messages such as warnings or special conditions. This standardization in flash rates is crucial for navigation safety, enabling vessel operators to recognize the purpose of the light quickly.

Understanding the correct flashing rate plays a significant role in various scenarios, such as identifying the presence of vessels engaged in specific activities or indicating hazards along navigable waters. Thus, the answer aligns with U.S. Coast Guard regulations and practices, making it the accurate choice for this question.
