Are there engine compartment ventilation requirements for diesel-fueled boats?
A. ABYC Standard H-32, Ventilation Of Boats Using Diesel Fuel states “power or natural ventilation is not required on a diesel boat, but may be used to control compartment temperature.” The standard also provides guidance on other ventilation considerations such as supplying necessary combustion air, venting hydrogen gas from batteries when appropriate, and removing the discharge from fixed gaseous fire extinguishing systems.
