Inboard gas boats built after 1980 must have what type of ventilation system?

Inboard gas boats built after 1980 must be equipped with a ventilation system that includes both natural and powered ventilation. This system is designed to prevent the accumulation of flammable gases in engine compartments, ensuring safety during operation. Typically, it requires at least two ventilators: one for intake and one for exhaust, to facilitate adequate airflow. Compliance with these ventilation standards is essential for meeting safety regulations.
