A natural ventilation system must be approved for use by the United States Coast Guard and include a supply opening or duct from the atmosphere or from a ventilated compartment or from a compartment that is open to the atmosphere, and an exhaust opening into another ventilated compartment or an exhaust duct to the atmosphere. Each exhaust opening or duct must originate in the lower third of the compartment; and each supply opening or duct and each exhaust opening or duct in a compartment must be above the normal accumulation of bilge water.
