The purpose of navigational lights is to _____________ vessels of another boat's presence.

The purpose of navigational lights is to inform vessels of another boat's presence, which is essential for maritime safety. These lights help boat operators understand the position, direction, and type of other vessels, especially in low visibility conditions such as nighttime or inclement weather. By using a standardized system of colored lights, mariners can quickly assess what type of vessel they are encountering (for example, whether it is anchored, underway, or crossing their path) and make informed decisions to avoid collisions. This crucial system of communication promotes safe navigation and is a primary responsibility for all boat operators to ensure the safety of their vessel and crew, as well as others on the water.
