 Public Law 622 also required structural fire protection on passenger vessels and required plans for passenger vessels be approved by the Bureau prior to any vessels construction.The Motorboat Act of 1940 was enacted to cover safety requirements for every vessel propelled by machinery and not more than 65 feet (19.8 meters) in length, with the exception of tugboats and towboats of this length propelled by steam, which were covered under other laws.In addition to covering safety equipment, running lights, and reckless or negligent operations, this law gave the Bureau of Marine Inspection and Navigation the authority to examine the operators of these boats and issue licenses provided they carried passengers for hire.
