Understanding Minnesota's Boat Light Requirements

For boats less than 16 feet in length, Minnesota law requires a white all-around light visible from all directions. This light must be displayed between sunset and sunrise, or during periods of reduced visibility. The light should be mounted on the forward part of the boat, at a height that ensures it can be seen from a distance.

Additionally, boats under 16 feet that are operating during periods of reduced visibility must also display a red and green side light. These lights should be visible from a distance of at least 2 miles and should be mounted on either side of the boat, with the red light on the port (left) side and the green light on the starboard (right) side.

Lights for Boats with Engines Not in Use

It's important to note that even if your boat's engine is not in use, you are still required to display the appropriate lights if you are operating your boat under sail or using a motorized trolling device. This is to ensure your boat's visibility to other boaters, regardless of how you are propelling your vessel.

Additionally, boats operating in a regatta or other organized event may have different lighting requirements. Always check with the event organizers for specific lighting guidelines if you plan to participate in such events.

Understanding and adhering to Minnesota's boat light laws is not just a legal requirement, but also a crucial aspect of boating safety. By ensuring your boat is properly equipped with the necessary lights, you are helping to prevent collisions and enhance the overall safety of your boating experience. So, the next time you head out onto Minnesota's waters, make sure you're not just ready to enjoy the ride, but also ready to navigate safely and in compliance with the law.
