Title 46 › Subtitle V — Merchant Marine › Part E — Control of Merchant Marine Capabilities › CHAPTER 561 — RESTRICTIONS ON TRANSFERS › § 56101
You must get approval from the Secretary of Transportation before you sell, lease, charter, deliver, or otherwise transfer control of a U.S.-documented vessel or a vessel last documented in the United States to someone who is not a U.S. citizen. You also must get approval before you put a documented U.S. vessel under a foreign flag or operate it under a foreign country’s authority. This requirement can be limited by other laws (including section 12119 or section 611 of the Merchant Marine Act, 1936). Vessels used only for pleasure or only for fishing (including fish processing or fish tender boats) are not covered by the transfer rule. The Secretary can give approval before a vessel is officially documented to help with financing. A vessel may be put under a foreign flag without approval only if the owner documents a replacement vessel with equal or greater military capability and similar or greater capacity (measured by deadweight tons, gross tons, or container equivalent units) that is not more than 10 years old, or if an applicable operating agreement has expired. Any transfer done in violation is void. Knowingly breaking these rules can bring up to 5 years in prison, fines under federal law, civil penalties up to $10,000 per violation, and the vessel can be seized. For passenger-vessel charters, the Maritime Administrator must publish requests and final decisions on the Maritime Administration website after public notice and comment.
