Title 46 › Subtitle V — Merchant Marine › Part A — General › CHAPTER 501 — POLICY, STUDIES, AND REPORTS › § 50103
The Secretary of Transportation must study and keep up-to-date lists of ocean routes and services from U.S. ports to foreign markets that are needed to support and grow U.S. trade and meet national defense needs. When deciding which routes are essential, the Secretary must look at the cost to run each route, whether a route would lose money, how often trips should run and what kinds of ships to use, the benefit to trade and defense, and any other business facts a careful manager would consider. The Secretary must also plan for the Saint Lawrence Seaway’s seasonal closing and set alternate port routes so service continues year-round. The Secretary must also record what bulk-cargo services U.S. ships should provide and decide the kinds of vessels (size, speed, engines, including express-liner or super-liner ships) and the regularity of voyages needed to give steady, reliable service.
