MN Law Requires Carbon Monoxide Detectors for Boats with Cabins

Sophia’s Law went into effect in Minnesota on May 1. Named for a seven-year-old who died from carbon monoxide poisoning while boating, the law mandates carbon monoxide detectors on boats with enclosed accommodation compartments. Enclosed accommodation compartments include designated sleeping space, a galley with a sink and/or a head compartment. Minnesota is the first state to require CO detectors in motorboats.

Per the American Boat and Yacht Council (ABYC) standard A-24  Carbon Monoxide Detection Systems, July 2015, detectors must be located to monitor the atmosphere in the main cabin and each sleeping area. Carbon monoxide detectors manufactured prior to 2012 should be replaced.

In addition, all gasoline-powered motorboats with any enclosed space designed for a person to enter must display three CO poisoning warning stickers. The stickers are to be placed at the helm, at the stern and at the entrance to any enclosed occupancy space.

Carbon monoxide (CO) is an odorless, colorless, tasteless gas that can be toxic even in very small quantities since its effects are cumulative over time. A quick inspection every time you operate your boat can save a life, carbon monoxide poisonings are preventable

Although it is not required, motorboats with diesel engines are urged to display the stickers warning boaters of the dangers of CO poisoning especially if they also have generators or other fuel burning appliances.

The first violation will be a safety warning; additional violations are a petty misdemeanor.
