Final Answer:
All boats must display an all-around anchor light between sunrise and sunset or in restricted visibility conditions when at anchor.
Step-by-step explanation:
Boats are required to exhibit an all-around anchor light during the period between sunrise and sunset, and also in instances of restricted visibility when anchored. The purpose of this regulation is to enhance the visibility of anchored vessels, ensuring the safety of navigation for other watercraft. During daylight hours, the anchor light serves as a supplementary signal to alert nearby vessels of the boat's stationary status. In conditions of restricted visibility, such as fog or heavy rain, displaying the anchor light becomes crucial for indicating the presence and location of the anchored boat to avoid collisions.
The requirement for an all-around anchor light is stipulated by international maritime rules, such as those outlined in the International Regulations for Preventing Collisions at Sea (COLREGs). These regulations aim to establish a standardized set of rules to prevent collisions at sea and ensure the safety of all vessels.
By mandating the use of anchor lights during specific periods, authorities promote a consistent and universally understood signaling system, contributing to the overall safety and orderliness of maritime traffic. Therefore, compliance with these regulations is essential for every boat operator to uphold a secure and well-regulated maritime environment.
