When navigating at night you see a boat displaying two all-round lights in a vertical line the top light is green and the bottom light is white?

When it comes to boat navigation lights, it’s every owner’s responsibility to make sure their boat complies. If your boat is out on the water between sunset and sunrise, you need lights. Even during low light conditions during the day, you may need lights. Whether you are anchored or underway, having the right lights onboard helps keep you, your passengers and other water users safe.

Navigational lights tell other skippers what your boat is doing – anchored, motoring, or under sail - so they can predict your movement and anticipate the potential danger of a collision.
 

What are the Different Navigation Lights?

  • Masthead – a white light over the centerline of the vessel. It provides an unbroken light over an arc of the horizon of 225 degrees. The light should be fixed to show from anywhere ahead to just behind the vessel’s beams.  

  • All-Round White Light – an unbroken light over an arc of the horizon of 360 degrees.

  • Sidelights – a green light on the starboard side and red light on the port side of a vessel. It provides an unbroken light over an arc of the horizon of 112.5 degrees.

  • Sternlight – a white light placed near the stern providing an unbroken light over an arc of the horizon of 135 degrees.
