These lights allow other boaters to determine the direction in which the vessel is traveling. A green sidelight is positioned on the starboard (right) side, while a red sidelight is positioned on the port (left) side.
  • Sternlight: The sternlight is a white light mounted at the rear or stern of a boat. It helps other boaters identify the presence and position of your vessel, especially when approaching from behind.
  • Masthead light: This white light is positioned on top of the vessel’s mast or highest structure. It is visible from both the front and back of the boat and is used to indicate the presence of a vessel in darker conditions. The masthead light should be displayed in addition to the sidelights.
  • All-round white light: For certain vessels, an all-round white light is used instead of separate sidelights and sternlights. This light can be mounted on the highest point of the boat and must provide visibility from 360 degrees.

Required Navigation Lights For Recreational Vessels

If you own a recreational boat, there are essential navigation lights that you must have to comply with boating regulations. These lights include:

  • Bow lights: Recreational vessels measuring less than 12 meters (39.4 feet) are required to display red and green sidelights on the bow. The lights should be visible at a distance of at least one nautical mile.
  • Stern light: A recreational boat must also have a white sternlight visible at a distance of at least two nautical miles. This light should be displayed at the boat’s stern or mounted higher if possible.

Additional Lights For Commercial And Larger Vessels

Commercial and larger vessels have additional requirements when it comes to navigation lights. These additional lights include:

  • Towing light: If your vessel is towing another boat or object, you need to display a yellow towing light above the sternlight. This light warns other boaters about the presence of a towed object.
  • Anchor light: When a vessel is at anchor, it must display an anchor light. This light is a white, all-round light visible for at least two nautical miles and helps other boaters identify an anchored vessel.
  • Fishing light: Some larger fishing vessels may also require specialized lights, such as lights to attract fish or lights to indicate nets or gear in the water. These lights help improve safety and awareness for both the fishing vessel and other boaters in the area.
