What is the primary purpose of the Jones Act?

The primary purpose of the Jones Act is to provide for the promotion and maintenance of the American merchant marine. Enacted in 1920, the Jones Act, formally known as the Merchant Marine Act of 1920, was established to support and protect the U.S. maritime industry. It emphasizes the importance of having a strong domestic shipping capability, which is vital for national security and economic sustainability. The act mandates that only U.S.-built, owned, and crewed vessels can transport goods between U.S. ports, ensuring that American maritime jobs and shipbuilding industries are maintained. By promoting a robust merchant marine, the Jones Act plays a crucial role in safeguarding the nation's maritime interests and economic independence.

The other options do not accurately capture the key focus of the Jones Act. While it may touch related areas such as passenger transportation and environmental regulations indirectly, its core intent is to bolster the U.S. merchant marine's overall strength and viability.
