§12102 Vessels Requiring Documentation

Title 46 › Subtitle II — Vessels and Seamen › Part H — Identification of Vessels › CHAPTER 121 — DOCUMENTATION OF VESSELS › SUBCHAPTER I — GENERAL › § 12102

Summary

A vessel can do a trade only if it has a certificate of documentation with the proper endorsement, unless another rule says otherwise. A vessel under 5 net tons can work without that documentation if it meets the trade’s rules. A barge allowed for the coastwise trade can do that trade without documentation on rivers, harbors, canals, inland waters, and lakes except the Great Lakes. Even if section 12113 or other laws would stop it, the Secretary of Transportation can issue a waiver to let a documented vessel with a registry endorsement or a foreign‑flag vessel help treat or protect aquaculture fish when no suitable U.S. vessel is available and a notice is published in the Federal Register. A vessel using that waiver cannot do any coastwise transportation.

(a)In General.—
Except as otherwise provided, a vessel may engage in a trade only if the vessel has been issued a certificate of documentation with an endorsement for that trade under this chapter.
(b)Vessels Less Than 5 Net Tons.—
A vessel of less than 5 net tons may engage in a trade without being documented if the vessel otherwise satisfies the requirements to engage in the particular trade.

Notwithstanding section 12113 and any other law, the Secretary of Transportation may issue a waiver allowing a documented vessel with a registry endorsement or a foreign flag vessel to be used in operations that treat aquaculture fish for or protect aquaculture fish from disease, parasitic infestation, or other threats to their health if the Secretary finds, after publishing a notice in the Federal Register, that a suitable vessel of the United States is not available that could perform those services.
(2)Prohibition.—
Vessels operating under a waiver issued under this subsection may not engage in any coastwise transportation.
