What is the minimum visibility required for navigation lights on unpowered vessels less than 39.4 feet long?

The minimum visibility required for navigation lights on unpowered vessels less than 39.4 feet long is set at one mile. This requirement ensures that vessels can be seen by other boaters in various visibility conditions, particularly during low-light scenarios such as dawn, dusk, or nighttime.

Having a minimum visibility standard helps to enhance safety on the water, allowing both the unpowered vessel and any potential powerboats or other vessels to maintain a safe distance and avoid collisions. It is especially crucial for smaller vessels, which may have less presence on the water, to be visible to larger vessels that may be operating at higher speeds. By adhering to this one-mile visibility requirement, operators of unpowered vessels contribute to safer navigation for everyone on the water.
