What type of ventilation systems do boats after July 31 1980 have?

Boats built after July 31, 1980, are required to have adequate ventilation systems that comply with the standards set by the American Boat and Yacht Council (ABYC) and the U.S. Coast Guard. These systems typically include natural ventilation through vents and hatches, as well as mechanical ventilation systems to ensure proper airflow in enclosed spaces, particularly in areas where fuel vapors may accumulate. The goal is to reduce the risk of fire and ensure the safety of passengers and crew.
