Where on a Boat is the Green Navigation Side Light Located?

Understanding the Importance of Side Lights

When navigating a boat, understanding the placement and usage of side lights is crucial for safe and effective maritime travel. Side lights, specifically the green and red ones, help ensure that other vessels can identify your boat's position and direction. These lights are particularly important in low visibility conditions, night time, or in fog.

Standard Locations of Side Lights

The starboard (right) green side light and the port (left) red side light are typically located above the deck lights and below the mast light if the mast light is at the top of the mast. This arrangement ensures clear visibility from a distance and adheres to international maritime regulations.

Navigational Regulations

The configuration of side lights on vessels is regulated by the International Regulations for Preventing Collisions at Sea 1972 (COLREGS). This treaty is implemented in national legislation worldwide, with rule 21 and Appendix 1 providing specific instructions on the positions of these lights.

Location of Green and Red Side Lights

Irrespective of the vessel type, the starboard (right-hand) green side light should be positioned to the right of the vessel when viewed from the front. Conversely, the port (left-hand) red side light should be positioned to the left of the vessel. This makes it easy to identify the direction of the boat and ensures other vessels are aware of the boat's position.

Memory Aid: Port - Red; Starboard - Green

To remember the locations, it helps to use a simple mnemonic. Here's one approach:

Port red left: The port red light is to the left. Starboard green right: The starboard green light is to the right.

Remembering this can make it easier to ensure that your boat is in compliance with navigation rules.

Compliance and Safety

Compliance with these regulations is essential not only for legal reasons but also to ensure the safety of all vessels involved in maritime travel. Proper positioning of side lights helps to avoid collisions and ensures smooth navigation.

Conclusion

Understanding the placement and usage of navigational side lights is a fundamental requirement for any responsible boat captain or navigator. By adhering to international regulations and using simple memory aids, you can ensure that your vessel is properly equipped for safe and effective navigation.
