Transportation in Puerto Rico includes a system of roads, highways, freeways, airports, ports and harbors, and railway systems, serving a population of approximately 4 million year-round. It is funded primarily with both local and federal government funds.
Maritime transport or more generally waterborne transport, is the transport of people (passengers) or goods (cargo) via waterways. Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air or ground, but significantly slower for longer distances. Maritime transport accounts for roughly 80% of international trade, according to UNCTAD in 2020.
Admiralty law or maritime law is a body of law that governs nautical issues and private maritime disputes. Admiralty law consists of both domestic law on maritime activities, and private international law governing the relationships between private parties operating or using ocean-going ships. While each legal jurisdiction usually has its own legislation governing maritime matters, the international nature of the topic and the need for uniformity has, since 1900, led to considerable international maritime law developments, including numerous multilateral treaties.
The United States Merchant Marine is an organization composed of United States civilian mariners and U.S. civilian and federally owned merchant vessels. Both the civilian mariners and the merchant vessels are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports domestic and international cargo and passengers during peacetime, and operate and maintain deep-sea merchant ships, tugboats, towboats, ferries, dredges, excursion vessels, charter boats and other waterborne craft on the oceans, the Great Lakes, rivers, canals, harbors, and other waterways. In times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military.
The United States Merchant Marine Academy is a United States service academy in Kings Point, New York. It trains its midshipmen to serve as officers in the United States Merchant Marine, branches of the United States Armed Forces and the transportation industry. Midshipmen are trained in different fields such as marine engineering, navigation, ship's administration, maritime law, personnel management, international law, customs, and many other subjects important to the task of running a large ship.
The United States Shipping Board (USSB) was established as an emergency agency by the 1916 Shipping Act, on September 7, 1916. The United States Shipping Board's task was to increase the number of US ships supporting the World War I efforts. The program ended on March 2, 1934.
The National Defense Reserve Fleet (NDRF) consists of ships of the United States, mostly merchant vessels, that have been mothballed but can be activated within 20 to 120 days to provide shipping during national military emergencies, or non-military emergencies such as commercial shipping crises.
The United States Maritime Commission (MARCOM) was an independent executive agency of the U.S. federal government that was created by the Merchant Marine Act of 1936, which was passed by Congress on June 29, 1936, and was abolished on May 24, 1950. The commission replaced the United States Shipping Board which had existed since World War I. It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to replace the World War I vintage vessels that comprised the bulk of the United States Merchant Marine, and to administer a subsidy system authorized by the Act to offset the cost differential between building in the U.S. and operating ships under the American flag. It also formed the United States Maritime Service for the training of seagoing ship's officers to man the new fleet.
The Merchant Marine Act of 1920 is a United States federal statute that provides for the promotion and maintenance of the American merchant marine. Among other purposes, the law regulates maritime commerce in U.S. waters and between U.S. ports. Section 27 of the Merchant Marine Act is known as the Jones Act and deals with cabotage. It requires that all goods transported by water between U.S. ports be carried on ships that have been constructed in the United States and that fly the U.S. flag, are owned by U.S. citizens, and are crewed by U.S. citizens and U.S. permanent residents. The act was introduced by Senator Wesley Jones. The law also defines certain seaman's rights.
The War Shipping Administration (WSA) was a World War II emergency war agency of the US government, tasked to purchase and operate the civilian shipping tonnage the United States needed for fighting the war. Both shipbuilding under the Maritime Commission and ship allocation under the WSA to Army, Navy or civilian needs were closely coordinated though Vice Admiral Emory S. Land who continued as head of the Maritime Commission while also heading the WSA.
The Emergency Fleet Corporation (EFC) was established by the United States Shipping Board, sometimes referred to as the War Shipping Board, on 16 April 1917 pursuant to the Shipping Act to acquire, maintain, and operate merchant ships to meet national defense, foreign and domestic commerce during World War I.
The United States Maritime Service (USMS) was established in 1938 under the provisions of the Merchant Marine Act of 1936 as voluntary training organization to train individuals to become officers and crewmembers on merchant ships that form the United States Merchant Marine per 46 U.S.C. § 51701. Heavily utilized during World War II, the USMS was largely dissolved in 1954, and its resources were absorbed into other federal departments. However, while the service is no longer structurally organized, remnants of the service still exist today and the service still actively commissions officers to function as administrators and instructors at the United States Merchant Marine Academy and the state maritime academies.
A sea captain, ship's captain, captain, master, or shipmaster, is a high-grade licensed mariner who holds ultimate command and responsibility of a merchant vessel. The captain is responsible for the safe and efficient operation of the ship, including its seaworthiness, safety and security, cargo operations, navigation, crew management, and legal compliance, and for the persons and cargo on board.
The Steamboat Inspection Service was a United States agency created in 1871 to safeguard lives and property at sea. It merged with the Bureau of Navigation in 1932 to form the Bureau of Navigation and Steamboat Inspection, which in 1936 was reorganized into the Bureau of Marine Inspection and Navigation. The Bureau of Marine Inspection and Navigation's responsibilities were transferred temporarily to the United States Coast Guard in 1942. The Bureau was abolished in 1946, when its functions were transferred permanently to the Coast Guard.
The maritime history of the United States is a broad theme within the history of the United States. As an academic subject, it crosses the boundaries of standard disciplines, focusing on understanding the United States' relationship with the oceans, seas, and major waterways of the globe. The focus is on merchant shipping, and the financing and manning of the ships. A merchant marine owned at home is not essential to an extensive foreign commerce. In fact, it may be cheaper to hire other nations to handle the carrying trade than to participate in it directly. On the other hand, there are certain advantages, particularly during time of war, which may warrant an aggressive government encouragement to the maintenance of a merchant marine.
The Maritime history of the United States (1776–1799) begins with the British colonists before 1776, American merchant vessels had enjoyed the protection of the Royal Navy. During the American Revolution, American ships came under the aegis of France due to a 1778 Treaty of Alliance between the two countries.
The United States merchant marine forces matured during the maritime history of the United States (1900–1999).
The Long Range Shipbuilding program was implemented by the U.S. Maritime Commission shortly after its establishment in 1937 as part of the mandate of the Merchant Marine Act of 1936 which stated that:
United States shall have a merchant marine
(a) sufficient to carry its domestic water-borne commerce and a substantial portion of the water-borne export and import foreign commerce of the United States and to provide shipping service on all routes essential for maintaining the flow of such domestic and foreign water-borne commerce at all times
(b) capable of serving as a naval and military auxiliary in time of war or national emergency,
(c) owned and operated under the United States flag by citizens of the United States insofar as may be practicable, and
(d) composed of the best-equipped, safest, and most suitable types of vessels, constructed in the United States and manned with a trained and efficient citizen personnel. It is hereby declared to be the policy of the United States to foster the development and encourage the maintenance of such a merchant marine.
The Cargo Preference Act or Cargo Preference refers generally to legal requirements for the carriage of government-impelled cargoes on the vessels flagged within the registry of that government for the purpose of promoting a national merchant marine. Cargo Preference is commonplace among the world's seafaring nations, including Australia, Brazil, France, Japan, Taiwan.
The foreign and intergovernmental relations of Puerto Rico are governed by the Commerce and Territorial Clause of the Constitution of the United States. Because of this, they are subject to the plenary powers of Congress. Nonetheless, Puerto Rico has established relations with foreign nations, particularly with Hispanic American countries such as Colombia and Panamá. The establishment of such relations, however, requires permission from the U.S. Department of State or Congress itself. Still, most relations are already set by existent laws or trade agreements established beforehand by the United States that supersede the relation pursued by Puerto Rico.
