What is the visibility requirement for power-driven vessels under 65 feet?

The visibility requirement for power-driven vessels under 65 feet is that they must display an all-around white light that is visible for 2 miles. This requirement is in accordance with maritime regulations aimed at ensuring the safety of navigation and preventing collisions at sea. The all-around white light serves as a signal to other vessels about the presence and heading of the power-driven vessel, especially during times of limited visibility, such as at night or in fog.

Having a light that is visible for 2 miles provides a sufficient range for other vessels in the area to detect and identify the power-driven vessel, aiding in the overall safety of marine navigation. The use of side lights alone or daytime visibility only would not provide adequate warning to other vessels, especially during nighttime or low visibility conditions. High-intensity spotlights, while useful for specific purposes, do not meet the standardized requirement for visibility that is set for vessels to ensure safe operations at sea.
