The purpose of this legislation, known as the "Safeguarding American Tourism Act," is to exempt large cruise ships from certain existing legal requirements that apply to passenger vessels. The goal is to facilitate the operation of these cruise ships, potentially boosting tourism and economic activity in the United States. Key provisions of the law include changes to the Passenger Vessel Services Act (PVSA) and the Jones Act. Specifically, the law states that vessels with 800 or more passenger berths will not be subject to certain domestic requirements under the PVSA.
