What Color Lights Are Best on a Boat?

When it comes to boating, having proper lighting is essential for safety and navigation. But what color lights are best on a boat? Let’s explore the different types of boat lighting and their recommended colors.

Navigation Lights

Navigation lights are required by law on all vessels underway between sunset and sunrise. They indicate the boat’s direction of travel and alert other boats to your presence. Navigation lights come in three colors: red, green, and white.

  • Red: The port side of the boat should have a red light. This light indicates that the vessel is approaching from the left or port side.
  • Green: The starboard side of the boat should have a green light. This light indicates that the vessel is approaching from the right or starboard side.
  • White: A white light should be visible from all directions, indicating that the vessel is underway.

Masthead Lights

Masthead lights are located at the top of a sailboat’s mast or on a powerboat’s bow. They are used to indicate that a vessel is under power and its length. Masthead lights can be either white or yellow.

  • White: A white masthead light indicates that the boat is under power and less than 50 meters in length.
  • Yellow: A yellow masthead light indicates that the boat is under power and over 50 meters in length.

Stern Light

A stern light is located at the back of a boat and indicates its position to other vessels. It can be either white or yellow.

  • White: A white stern light indicates that the boat is under power and less than 50 meters in length.
  • Yellow: A yellow stern light indicates that the boat is under power and over 50 meters in length.

Anchor Light

An anchor light is used when a boat is at anchor. It indicates the boat’s position to other boats and should be visible from all directions. Anchor lights are typically white.

Underwater Lights

Underwater lights are not required for safety or navigation but can enhance the appearance of a boat. They come in various colors, including blue, green, red, and white. However, it’s important to note that certain colors can attract marine life, which may disrupt their natural habitat.

In Conclusion

The color of boat lights depends on their purpose and location on the vessel. Navigation lights should always be red, green, or white as required by law.

Masthead and stern lights can be either white or yellow depending on the length of the boat. Anchor lights are typically white, while underwater lights come in various colors but may attract marine life.

Remember to always follow boating laws and regulations regarding lighting to ensure your safety and that of others on the water.
