How is a Coastwise vessel different from other vessels?

A Coastwise vessel is characterized primarily by its engagement in domestic trade, operating between ports within the United States without crossing international boundaries. This is a critical distinction because such vessels are essential for transporting goods and passengers between various ports along the coast, contributing significantly to the domestic economy.

Other types of vessels may operate internationally, carrying cargo or passengers across borders, or may serve specific purposes, such as tourism. However, Coastwise vessels focus on intra-country movement, adhering to regulations that apply specifically to domestic maritime commerce. They play a vital role in maintaining trade routes along the coastline and ensuring accessibility across various states.

Regarding size, while some Coastwise vessels can be large, their classification is not based on size but primarily on their operating limits and the type of trade they engage in. Thus, the definition of a Coastwise vessel is firmly rooted in its function and operational scope.
