Navigating Boat Navigation Lights: Identifying Key Markings

Where Are the Red and Green Side Lights on a Boat?

When it comes to boating, safety should always be a top priority. One essential safety feature on boats is the navigation lights, which help other boaters determine your vessel’s direction and status, especially during low visibility conditions. Two crucial navigation lights are the red and green side lights.

Understanding Navigation Lights

Navigation lights are color-coded and strategically positioned on boats to indicate their orientation to other vessels. The red and green side lights, also known as port and starboard lights respectively, provide important information about a boat’s course.

The Red Side Light (Port Light)

The red side light is located on the left side of the boat when facing forward. It is essential for indicating the port (left) side of the vessel to other boaters. This light should be visible from at least 112.5 degrees aft (from directly behind) to 22.5 degrees forward on the port side.

Note: The red light is always displayed on the left side of a boat regardless of its direction or movement.

The Green Side Light (Starboard Light)

The green side light is positioned on the right side of the boat when facing forward, opposite to the red light. It denotes the starboard (right) side of the vessel to other boaters. Similar to the red light, it should be visible from at least 112.5 degrees aft to 22.5 degrees forward on the starboard side.

Note: The green light is always displayed on the right side of a boat regardless of its direction or movement.

When Are Navigation Lights Required?

Navigation lights are required to be displayed on a boat during specific periods, such as:

  • Between sunset and sunrise
  • During periods of restricted visibility (e.g., fog, heavy rain, or haze)

Note: Navigation lights should also be displayed during daylight hours if visibility is significantly reduced.

Other Important Considerations

Here are some additional points to keep in mind regarding navigation lights:

  • The lights must be visible from a distance of at least two nautical miles.
  • The intensity of the lights should not be excessive, as it may impair the vision of other boaters.
  • The navigation lights must be installed and maintained properly to ensure their functionality.

In Conclusion

Understanding the placement and significance of the red and green side lights on a boat is crucial for safe navigation. These lights allow other boaters to determine your vessel’s orientation and course, ensuring a safer boating experience for all.
