The United States Merchant Marine   refers to either United States civilian mariners, or to 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 cargo and passengers during peacetime; 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 material for the military.  Merchant Marine officers may also be commissioned as military officers by the Department of Defense. This is commonly achieved by commissioning unlimited tonnage Merchant Marine officers as Strategic Sealift Officers in the Naval Reserves.   
Merchant mariners move cargo and passengers between nations and within the United States, 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. 
As of December 31, 2016, the United States merchant fleet had 175 privately owned, oceangoing, self-propelled vessels of 1,000 gross register tons and above that carry cargo from port to port or more.  Nearly 800 American-owned ships are flagged in other nations.  
The federal government maintains fleets of merchant ships via organizations such as Military Sealift Command (part of the US Navy) and the National Defense Reserve Fleet,  which is managed by the United States Maritime Administration. In 2004, the federal government employed approximately 5% of all American water transportation workers. 
In the 19th and 20th centuries, various laws fundamentally changed the course of American merchant shipping. These laws put an end to common practices such as flogging and shanghaiing,  and increased shipboard safety and living standards. The United States Merchant Marine is also governed by more than 25 (as of February 17, 2017)   international conventions to promote safety and prevent pollution. 
P.L. 95–202, approved November 23, 1977, granted veteran status to Women Airforce Service Pilots and "any person in any other similarly situated group" with jurisdiction for determination given to the Secretary of Defense who delegated that determination to the Secretary of the Air Force.  Although the Merchant Marine suffered a per capita casualty rate greater than those of the US Armed Forces, merchant mariners who served in World War II were denied such veterans recognition until 1988 when a federal court ordered it. The Court held that "the Secretary of the Air Force abused its discretion in denying active military service recognition to American merchant seamen who participated in World War II."

Captains, mates (officers), and pilots supervise ship operations on domestic waterways and the high seas. A captain (master) is in overall command of a vessel, and supervises the work of other officers and crew. A captain has the ability to take the conn from a mate or pilot at any time he feels the need. On smaller vessels the captain may be a regular watch-stander, similar to a mate, directly controlling the vessel's position. Captains and department heads  ensure that proper procedures and safety practices are followed, ensure that machinery is in good working order, and oversee the loading and discharging of cargo and passengers. Captains directly communicate with the company or command ( MSC), and are overall responsible for cargo, various logs, ship's documents, credentials, efforts at controlling pollution and passengers carried.[ citation needed]
Mates direct a ship's routine operation for the captain during work shifts, which are called watches. Mates stand watch for specified periods, usually in three duty sections, with four hours on watch and eight hours off.  When on a navigational watch, mates direct a bridge team by conning, directing courses through the helmsman and speed through the lee helmsman (or directly in open ocean). When more than one mate is necessary aboard a ship, they typically are designated chief mate or first mate, second mate and third mate. In addition to watch standers, mates directly supervise the ship's crew, and are assigned other tasks. The chief mate is usually in charge of cargo, stability and the deck crew, the second mate in charge of navigation plans and updates and the third mate as the safety officer. They also monitor and direct deck crew operations, such as directing line handlers during moorings, and anchorings, monitor cargo operations and supervise crew members engaged in maintenance and the vessel's upkeep.[ citation needed]
Harbor pilots guide ships in and out of confined waterways, such as harbors, where a familiarity with local conditions is of prime importance.  Harbor pilots are generally independent contractors who accompany vessels while they enter or leave port, and may pilot many ships in a single day.[ citation needed]
Engine officers, or engineers, operate, maintain, and repair engines, boilers, generators, pumps, and other machinery. Merchant marine vessels usually have four engine officers: a chief engineer and a first, second, and third assistant engineer. On many ships, Assistant Engineers stand periodic watches, overseeing the safe operation of engines and other machinery. However, most modern ships sailing today utilize Unmanned Machinery Space (UMS) automation technology, and Assistant Engineers are Dayworkers. At night and during meals and breaks, the engine room is unmanned and machinery alarms are answered by the Duty Engineer.[ citation needed]
Able seamen and ordinary seamen operate the vessel and its deck equipment under officer supervision and keep their assigned areas in good order.  They watch for other vessels and obstructions in the ship's path, as well as for navigational aids such as buoys and lighthouses. They also steer the ship, measure water depth in shallow water, and maintain and operate deck equipment such as lifeboats, anchors, and cargo-handling gear. On tankers, mariners designated as pumpmen hook up hoses, operate pumps, and clean tanks. When arriving at or leaving a dock, they handle the mooring lines. Seamen also perform routine maintenance chores, such as repairing lines, chipping rust, and painting and cleaning decks. On larger vessels, a boatswain — or head seaman — will supervise the work.[ citation needed]
Marine oilers and more experienced qualified members of the engine department, or QMEDs, maintain the vessel in proper running order in the engine spaces below decks, under the direction of the ship's engine officers. These workers lubricate gears, shafts, bearings, and other moving parts of engines and motors; read pressure and temperature gauges, record data and sometimes assist with repairs and adjust machinery. Wipers are the entry-level workers in the engine room, holding a position similar to that of ordinary seamen of the deck crew. They clean and paint the engine room and its equipment and assist the others in maintenance and repair work. With more experience, they become oilers and firemen.[ citation needed]
As of 2011, a typical deep-sea merchant ship has a captain, three mates, a chief engineer and three assistant engineers, plus six or more unlicensed seamen, such as able seamen, oilers, QMEDs, and cooks or food handlers known as stewards.  Other unlicensed positions on a large ship may include electricians and machinery mechanics. 
The history of ships and shipping in North America goes back at least as far as Leif Erikson, who established a short-lived settlement called Vinland in present-day Newfoundland.  The shipping industry developed as colonies grew and trade with Europe increased. As early as the 16th century, Europeans were shipping horses, cattle and hogs to the Americas. 
Spanish colonies began to form as early as 1565 in places like St. Augustine, Florida, and later in Santa Fe, New Mexico; San Antonio, Tucson, San Diego, Los Angeles and San Francisco. English colonies like Jamestown began to form as early as 1607. The connection between the American colonies and Europe, with shipping as its only conduit, would continue to grow unhindered for almost two hundred years.  
The first wartime role of an identifiable United States Merchant Marine took place on June 12, 1775, in and around Machias, Massachusetts. A group of citizens, hearing the news from Concord and Lexington, captured the British schooner HMS Margaretta. The citizens, in need of critical supplies, were given an ultimatum: either load the ships with lumber to build British barracks in Boston, or go hungry. They chose to fight. 
Word of this revolt reached Boston, where the Continental Congress and the various colonies issued Letters of Marque to privateers.  The privateers interrupted the British supply chain all along the eastern seaboard of the United States and across the Atlantic Ocean. These actions by the privateers predate both the United States Coast Guard and the United States Navy, which were formed in 1790 and 1797, respectively. 
The merchant marine was active in subsequent wars, from the Confederate commerce raiders of the American Civil War, to the assaults on Allied commerce in the First and in the Second World Wars. 3.1 million tons of merchant ships were lost in World War II. Mariners died at a rate of 1 in 26, which was the highest rate of casualties of any service.  All told, 733 American cargo ships were lost  and 8,651 of the 215,000 who served perished in troubled waters and off enemy shores.
Merchant shipping also played its role in the wars in Vietnam and Korea. During the Korean War, under the operational control in theater of the Military Sea Transportation Service (MSTS), the number of chartered ships grew from 6 to 255. In September 1950, when the U.S. Marine Corps went ashore at Incheon, 13 Navy cargo ships, 26 chartered American, and 34 Japanese-manned merchant ships of the MSTS participated. 
During the Vietnam War, at least 172 National Defense Reserve Fleet (NDRF) ships were activated, and together with other US-flagged merchant vessels crewed by civilian seamen, carried 95% of the supplies used by the American armed forces.  Many of these ships sailed into combat zones under fire. The SS Mayaguez incident involved the capture of mariners from the American merchant ship SS Mayaguez. 
During the first Gulf War, the merchant ships of the Military Sealift Command (MSC) delivered more than 12 million metric tons of vehicles, helicopters, ammunition, fuel and other supplies and equipment. At one point during the war, more than 230 government-owned and chartered ships were involved in the sealift. 
As of January 2017, US Government-owned merchant vessels from the National Defense Reserve Fleet have supported emergency shipping requirements in 10 wars and crises.  During the Korean War, 540 vessels were activated to support military forces.  A worldwide tonnage shortfall from 1951 to 1953 required over 600 ship activations to lift coal to Northern Europe and grain to India.  The Department of Agriculture required 698 activated ships to store grain from 1955 through 1964.  After the Suez Canal Crisis in 1956, the NDRF activated 223 cargo ships and 29 tankers.  During the Berlin Wall Crisis of 1961, 18 NDRF vessels were activated, remaining in service until 1970.  The Vietnam War required the activation of 172 vessels. 
Since 1976, the Ready Reserve Fleet (RRF)    has taken the brunt of the work previously handled by the National Defense Reserve Fleet. The RRF made a major contribution to the success of Operation Desert Shield/ Operation Desert Storm from August 1990 through June 1992, when 79 vessels helped meet military sealift requirements by carrying 25% of the unit equipment and 45% of the ammunition needed. 
Two RRF tankers, two Roll-on/Roll-off (RO/RO) ships and a troop transport ship were employed in Somalia for Operation Restore Hope in 1993 and 1994. During the Haitian crisis in 1994, 15 ships were activated for Operation Uphold Democracy operations. In 1995 and 1996, four RO/RO ships were used to deliver military cargo as part of US and UK support to NATO peace-keeping missions. 
In 2003, 40 RRF ships were used in support of Operation Enduring Freedom and Operation Iraqi Freedom. This RRF contribution included sealifting into the combat theater equipment and supplies including combat support equipment for the Army, Navy Combat Logistics Force, and USMC Aviation Support equipment. By the beginning of May 2005, RRF cumulative support included 85 ship activations that logged almost 12,000 ship operating days, moving almost 25% of the equipment needed to support operations in Iraq. 
The Military Sealift Command was also involved in the Iraq War, delivering 61,000,000 square feet (5,700,000 m2) of cargo and 1,100,000,000 US gallons (4,200,000 m3) of fuel by the end of that year. Merchant mariners were recognized for their contributions in Iraq. For example, in late 2003, VADM David L. Brewer III, Military Sealift Command commander, awarded the crew of MV Capt. Steven L. Bennett the Merchant Marine Expeditionary Medal. 
The RRF was called upon to provide humanitarian assistance to gulf coast areas following Hurricane Katrina and Hurricane Rita landfalls in September 2005. The Federal Emergency Management Agency requested a total of eight vessels to support relief efforts. Messing and berthing was provided for refinery workers, oil spill response teams and longshoremen. One vessel provided electrical power. 
As of 2007, three RRF ships supported the US Army's Afloat Prepositioning Force (APF) with two specialized tankers and one dry cargo vessel capable of underway replenishment for the Navy's Combat Logistics Force. 
On October 22, 2015, a Military Sealift Command oiler and a United States civilian tanker refueled at sea during an exercise. This is not normally done as commercial fleet vessels are not normally geared for this type of exercise. This was done to increase operational readiness of MSC's naval auxiliary assets and prove flexibility of operation. 
As of 31 December 2016, the United States merchant fleet had 175 privately owned, oceangoing, self-propelled vessels of 1,000 gross register tons and above that carry cargo from port to port. One hundred fourteen (114) were dry cargo ships, and 61 were tankers. Ninety seven (97) were Jones Act eligible, and 78 were non-Jones Act eligible. MARAD deemed 152 of the 175 vessels "militarily useful." 
In 2005, there were also 77 passenger ships.[ citation needed] Of those American-flagged ships, 51 were foreign owned. Seven hundred ninety-four (794) American-owned ships are flagged in other nations.  
2005 statistics from the United States Maritime Administration focused on the larger segment of the fleet: ships of 10,000 tonnes deadweight (DWT) and over. Two hundred forty-five (245) privately owned American-flagged ships are of this size, and 153 of those meet the Jones Act criteria. 
The World War II era was the peak for the U.S. fleet. During the post-war year of 1950, for example, U.S. carriers represented about 43 percent of the world's shipping trade. By 1995, the American market share had plunged to 4 percent, according to a 1997 report by the U.S. Congressional Budget Office (CBO).  The report states, "the number of U.S.-flag vessels has dropped precipitously — from more than 2,000 in the 1940s and 850 in 1970 to about 320 in 1996." A diminishing U.S. fleet contrasted with the burgeoning of international sea trade. For example, worldwide demand for natural gas led to the growth of the global liquefied natural gas (LNG) tanker fleet, which reached 370 vessels as of 2007. In 2007 the United States Maritime Administration (MARAD) set uniform LNG training standards at U.S. maritime training facilities.  While short-term imports are declining,  longer term projections signal an eightfold increase in U.S. imported LNG by 2025, the worldwide LNG fleet does not include a single U.S. flagged vessel. Moreover, only five U.S. deepwater LNG ports were operational in 2007, although permits have been issued for four additional ports, according to MARAD. 
The US pool of qualified mariners declined with the fleet.  In 2004, MARAD described the gap between sealift crewing needs and available unlicensed personnel as "reaching critical proportions, and the long term outlook for sufficient personnel is also of serious concern." 
Future seagoing jobs for U.S. mariners may be on other than U.S.-flagged ships. American-trained mariners are being sought after by international companies to operate foreign-flagged vessels, according to Julie A. Nelson, deputy maritime administrator of the U.S. Maritime Administration.  For example, Shell International and Shipping Company Ltd. began recruiting U.S. seafarers to crew its growing fleet of tankers in 2008.  In 2007, Overseas Shipholding Group and the Maritime Administration agreed to allow American maritime academy cadets to train aboard OSG's international flag vessels.  In 2015, the average salary of American mariners was $39,000. 
The Military Sealift Command (MSC) — an arm of the Navy — serves the entire Department of Defense as the ocean carrier of material during peacetime and war. MSC transports equipment, fuel, ammunition, and other goods essential to United States armed forces worldwide. Up to 95% of all supplies needed to sustain the U.S. military can be moved by Military Sealift Command.  As of February 2017, MSC operated approximately 120 ships with 100 more in reserve. More than 5,500 civil service or contract merchant mariners staff the ships. 
MSC tankers and freighters have a long history of also serving as supply vessels in support of civilian research in the Arctic and Antarctic, including: McMurdo Station, Antarctica; and Greenland in the Arctic.  
The National Defense Reserve Fleet (NDRF)   acts as a reserve of cargo ships for national emergencies and defense. As of 31 January 2017, the NDRF fleet numbered 99 ships, down from 2,277 ships at its peak in 1950.   NDRF vessels are now staged  at the James River (off Ft. Eustis, VA); Beaumont, TX; and Suisun Bay (off Benicia, CA) anchorages, and other designated locations. 
A Ready Reserve Force   component of the NDRF was established in 1976 to provide rapid global deployment of military equipment and forces. As of January 2017, the RRF consists of 46 vessels, down from a peak of 102 vessels in 1994. Two RRF ships are homeported at the NDRF anchorage in Beaumont, TX, while the remainder are assigned to various other homeports. 
In 2014, the federal government reported directly employing approximately 5,100 seafarers, out of an industry total of over 78,000 water transportation workers in Occupation Code 53-5000, which represented about 6.5% of all water transportation workers,  many of whom worked on Military Sealift Command supply ships. By 2016, MSC reported employing more than 5,500 federal civilian mariners. 
Training and licensing are managed by the United States Coast Guard, guided by the United States Code of Federal Regulations Title 46, Chapter I, Subchapter B.  Training requirements are also molded by the International Convention on Standards of Training, Certification, and Watchkeeping for Seafarers (or STCW), which prescribes minimum standards that must be met.
Unlimited tonnage deck officers (referred to as mates) and engine officers are trained at maritime academies, or by accumulating sea-time as a rating on an unlimited tonnage ship along with passing certain training courses.  Officers hold senior leadership positions aboard vessels, and must train over several years to meet the minimum standards. At the culmination of training, potential deck officers must pass an extensive examination administered by the U.S. Coast Guard that spans five days. Upon meeting all requirements and passing the final license examination, new deck officers are credentialed as third mates or third assistant engineers. To advance in grade, such as to 2nd Mate or 2nd Engineer, sea time in the prior grade and additional endorsements and testing are required. The term "unlimited" indicates that there are no limits that the officer has in relation to the size and power of the vessel or geographic location of operation.
The U.S. Merchant Marine Academy (also known as USMMA or Kings Point) is one of the five United States service academies (the others are: the United States Military Academy, Naval Academy, Coast Guard Academy, and Air Force Academy), and one of seven United States maritime academies.  It is charged with training officers for the United States Merchant Marine, branches of the military, and the transportation industry.  
Joseph Banks Williams entered the Academy in 1942 and was the first African-American to graduate in 1944.   Admission requirements were further changed in 1974, when the USMMA became the first Federal service academy to enroll female students, two years before the other Federal service academies. 
Freshmen, known as " plebes," upon reporting in June or July of each year as the incoming class, begin a three-week indoctrination period, also known as "Indoc." Indoc is functionally run by upperclass midshipmen, but is overseen by officers of the United States Maritime Service who are part of the Commandant of Midshipman's staff. This high stress period involves physical training, marching, and an intensive introduction to regimental life at the academy. After the indoctrination period is completed, the academic year begins. 
U.S. citizen candidates for admission must sign a service obligation contract as a condition of admittance to the USMMA; U.S. candidates who completed Indoc will execute the Oath of Office as a Midshipman in the Navy Reserve the day prior to Acceptance Day.  Plebes officially become part of the USMMA Regiment of Midshipmen on Acceptance Day, which is now standardized at 2 weeks after Indoc ends.  Until they are "recognized" later in the academic year, plebes must continue adhere to stringent rules affecting most aspects of their daily life. After earning it, the plebes are recognized, henceforth accorded privilege of the title Midshipman, which gives them more privileges, known as "rates."
Academy students focus on one of two different ship transport areas of education: marine transportation or marine engineering. Transportation students learn about ship navigation, cargo handling, navigation rules, and maritime law. Engineering students learn about the function of the ship's engines and its supporting systems. There are currently five different academic majors conferring a Bachelor of Science degree in the major field of study available to midshipmen:
- Two of them are referred to as "Deck Majors":
- Marine Transportation, or
- Logistics and Intermodal Transportation; and
- "Deck Majors" sit for and, upon successfully completing the examination, are issued a Third Mate (Deck Officer) License of Steam or Motor Vessels, Unlimited Tonnage, Upon Oceans.
- The other three available curricula are referred to as "Engine Majors":
- Marine Engineering, or
- Marine Engineering Systems, or
- Marine Engineering and Shipyard Management, and
- "Engine Majors" sit for and, upon successfully completing the examination, are issued Third Assistant Engineer (3 A/E - Engineering Officer) Licenses Steam and Motor Vessels, Any Horsepower.
- Marine Engineering Systems and Marine Engineering Systems & Shipyard Management graduates are also qualified to sit for the Engineer In Training (EIT) examination administered by the National Council of Examiners for Engineering and Surveying (NCEES).
For part of sophomore and junior year, known at the Academy as third class and second class years, midshipmen work as cadets on American- flagged unlimited tonnage merchant ships. Midshipmen are typically paired two to a ship, one engine cadet and one deck cadet. Midshipmen work and function as part of the crew and gain an opportunity for generous amounts of hands-on experience as well as the opportunity to travel abroad to many different foreign ports. The average midshipman travels to 18 countries during this period, which totals a minimum of 300 days.  Due to this absence from the Academy, the remaining three academic years span from late July, through mid-June. 
Immediately upon taking the Oath of Office as naval reservists, the first year students become members of the US military, subject to various regulations, military discipline under the Uniform Code of Military Justice (UCMJ), and are subject to mobilization policies in the event of war or national emergency.   
USMMA graduates must maintain their merchant mariner licensing for 6 years following graduation, and must serve at least 5 years as either a merchant marine officer aboard a US-flagged vessel or with a maritime-related profession, OR 5 years of active duty service as a commissioned officer in any of the US Uniformed Services (Army, Navy, Marines, Air Force, Coast Guard, National Oceanic Atmospheric Administration (NOAA), or Public Health Service). All newly commissioned uniformed services officers, active or reserve component, will swear the Oath of Office and serve a minimum military service obligation of 8 years (any portion not served on active duty will be served in the reserve component).  
State maritime academies 
Like the Federal USMMA, the following six state maritime academies offer the same training and licensing opportunities for future United States Merchant Marine officers, with varying USCG-approved programs.  Each academy operates their own training ship, which are owned by the US Government and loaned to the academy. These ships act as training laboratories during the academic year, and are sailed on by the cadets during training cruises for months at a time.   One example of a training ship is USTS Golden Bear, at the California Maritime Academy.
- California Maritime Academy 
- Maine Maritime Academy 
- Massachusetts Maritime Academy 
- State University of New York Maritime College 
- Texas A&M Maritime Academy 
- The Great Lakes Maritime Academy 
Unlike midshipmen from the USMMA, students at any of the state maritime academies are not automatically appointed as members of the naval reserve, or any branch of the armed forces, nor are they guaranteed commissions as military officers. 
Merchant mariner license program cadets at any of the state maritime academies may apply for commission as a Strategic Sealift Officers in the Navy Reserves and are eligible to receive a $8,000  annual student incentive payment from MARAD. They must however, apply for and be accepted to a simultaneous-membership military service program consisting of both appointment as a midshipman in the Navy Reserve and reserve enlisted status.  After receiving the student incentive payments for 2 years, uniformed service obligations commence upon either graduation or dismissal for any reason from the program.   Graduates must comply with their state maritime academy enrollment agreements, and subsequent employment limitations, if any. Women were barred from all U.S. maritime academies until 1974, when the USMMA, State University of New York Maritime College, and the California Maritime Academy first admitted women cadets. 
An informal maritime industry term used to refer to a merchant ship's officer who began his or her career as an unlicensed merchant mariner and did not attend a traditional maritime college/academy to earn the officer's license. This term is similar in use and definition to a U.S. Naval Services "Mustang" who went from enlisted to officer. A hawsepiper earns their officer's license by attaining the required sea time as a rating, taking required training courses, and completing onboard assessments. When all requirements are met, the mariner can apply to the United States Coast Guard's National Maritime Center to take the license examination.
Unlicensed personnel (synonymous with ratings) are generally trained through several private programs funded by maritime unions, shipping companies, or by one's own expense. An example training institution would be the Paul Hall Center for Maritime Training and Education, or better known as "Piney Point." Generally the merchant mariner works their way up through the rates with sea time on the job. Entry level ratings would be ordinary seaman in the deck department and marine wiper in the engine department.
Unlicensed personnel must have sufficient sea time in a qualified rating and complete specified testing and training. These requirements are outlined in the International Convention on Standards of Training, Certification, and Watchkeeping for Seafarers ( STCW), to advance in rate.
Limited tonnage licensed mariners hold senior positions aboard small ships, boats, and similar vessels, but are restricted to certain tonnages (under 1600 GRT), types of vessels, and geographic locations. 
Several laws shaped the development of the U.S. Merchant Marine. Chief among them are the " Seamen's Act of 1915," the " Merchant Marine Act of 1920" (commonly referred to as the "Jones Act"), and the " Merchant Marine Act of 1936."[ citation needed]
The Seaman's Act  significantly improved working conditions for American Merchant Marine seamen.  The brainchild of International Seamen's Union president Andrew Furuseth, the Act was sponsored in the Senate by Robert Marion La Follette and received significant support from Secretary of Labor William B. Wilson.[ citation needed]
Among other things, the Act:
- abolished the practice of imprisonment for seamen who deserted their ship;
- reduced the penalties for disobedience;
- regulated working hours both at sea and in port;
- established minimum food quality standards;
- regulated the payment of wages;
- required specific levels of safety, particularly the provision of lifeboats;
- required a minimum percentage of the seamen aboard a vessel to be qualified Able Seamen; and
- required a minimum of 75% of the seamen aboard a vessel to understand the language spoken by the officers.
The Act's passage was attributed to labor union lobbying, increased labor tensions immediately before World War I, and elevated public consciousness of safety at sea due to the sinking of the RMS Titanic three years prior. 
The "Merchant Marine Act of 1920", often called "The Jones Act", required U.S.-flagged vessels to be built in the United States, owned by U.S. citizens, and documented ("flagged") under the laws of the United States. Documented means "registered, enrolled, or licensed under the laws of the United States". The Act also required that all officers and 75% of the crew be U.S. citizens. Vessels satisfying these requirements comprised the "Jones Act Fleet", and only these vessels were allowed to engage in " cabotage", or carrying passengers or cargo between two U.S. ports. There are countries in which, due to lower labor standards and prevailing wages, are much cheaper to document a vessel than the United States. Critics of the act claim it unfairly restricts the lucrative domestic shipping business. Another important aspect of the Act is that it allowed injured sailors to obtain compensation from their employers for the negligence of the owner, the captain, or fellow members of the crew.[ citation needed]
The Merchant Marine Act of 1936 was enacted "to further the development and maintenance of an adequate and well-balanced American merchant marine, to promote the commerce of the United States, to aid in the national defense, to repeal certain former legislation, and for other purposes."[ citation needed]
Specifically, the Act established the United States Maritime Commission and required a United States Merchant Marine that consisted of U.S.-built, U.S.-flagged, U.S.-crewed, and U.S.-owned vessels capable of carrying all domestic and a substantial portion of foreign water-borne commerce which could serve as a naval auxiliary in time of war or national emergency.[ citation needed]
The Act also established federal subsidies for the construction and operation of merchant ships. Two years after the Act was passed, the U.S. Merchant Marine Cadet Corps, the forerunner to the United States Merchant Marine Academy, was established.[ citation needed]
Federal law requires the Merchant Marine to adhere to a number of international conventions. The International Maritime Organization was either the source or a conduit for a number of these regulations.   
As of 2007, the principal International Conventions were:
- SOLAS 74: International Convention for the Safety of Life at Sea;
- MARPOL 73/78: International Convention for the Prevention of Pollution From Ships, 1973, as modified by the Protocol of 1978;
- ICLL 66: International Convention on Load Lines, as revised in 1966;
- 72 COLREGS: International Regulations for Preventing Collisions at Sea;
- STCW 95: International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW); and
- SAR 79: International Convention on Maritime Search and Rescue.

- On inland waters, able seamen may simply be called "deckhands."
- The size and service of the ship determine the number of crewmembers for a particular voyage.
- Small vessels operating in harbors, on rivers, or along the coast may have a crew comprising only a captain and one deckhand. The cooking responsibilities usually fall under the deckhands' duties. On larger coastal ships, the crew may include a captain, a mate or pilot, an engineer, and seven or eight seamen. Some ships may have special unlicensed positions for entry level apprentice trainees.
