Man Overboard: Maritime Law, Rescue Requirements, and What Happens After a Worker Falls Into the Water

How Federal Law Classifies a Fall Overboard

"Man overboard" is the familiar name for a person going from a vessel into the water. Under 46 C.F.R. § 4.03-1, a marine casualty or accident covers casualties involving vessels other than public vessels that occur on the navigable waters of the United States, its territories or possessions, or that involve any U.S. vessel wherever they occur, along with certain other situations the regulation lists. The regulation says the term applies to events "including, but not limited to: (i) Any fall overboard, injury, or loss of life of any person."

A fall overboard is therefore a marine casualty in itself, whether or not the person was hurt. For an injured worker, this means the event sits inside an official framework from the start, not only inside the employer's own paperwork. The fall and the rescue that followed can be seen as two parts of one event, since the rules touch both.

The risk is well known. The National Institute for Occupational Safety and Health's Commercial Fishing Safety page states that "the greatest dangers to fishermen are vessel disasters, falls overboard, and working with machinery on deck," and describes a fall overboard simply: "A crewmember falls off the vessel into water."

This page is written for commercial maritime workers and their families. A passenger going overboard from a cruise ship is a different situation and is outside this page. Deaths at sea have their own page on this site.

Throughout, which law applies turns on where the injury happened, the vessel, the waters and the injured person's status. A conversation with an attorney can help clarify which framework fits a particular set of facts.

Was the Vessel Required to Run Man Overboard Drills?

Two federal regulations speak directly to preparing for a person in the water, and each applies only to the vessels it covers.

On commercial fishing vessels, 46 C.F.R. § 28.270 provides in paragraph (a) that "the master or individual in charge of each vessel must ensure that drills are conducted and instruction is given to each individual on board at least once each month." The instruction must make each person familiar with their duties and responses to at least ten contingencies: abandoning the vessel; fighting a fire in different locations on board; recovering an individual from the water; minimizing the effects of unintentional flooding; launching survival craft and recovering lifeboats and rescue boats; donning immersion suits and other wearable personal flotation devices; donning a fireman's outfit and a self-contained breathing apparatus, if the vessel is so equipped; making a voice radio distress call and using visual distress signals; activating the general alarm; and reporting inoperative alarm systems and fire detection systems.

That monthly drill rule sits in a subpart that, under 46 C.F.R. § 28.200, applies to each documented commercial fishing industry vessel that operates beyond the Boundary Lines, operates with more than 16 individuals on board, or is a fish tender vessel engaged in the Aleutian trade. A fishing vessel outside those categories is not covered by this section. More on injured crew appears on our page about commercial fishing injuries.

On towing vessels, 46 C.F.R. § 140.405 provides in paragraph (b) that any towing vessel with alternating watches (shift work) or overnight accommodations must identify the duties and duty stations of each person on board during an emergency, including "taking action in the event of a person overboard." The broader rules for these vessels are covered on our page about tugboat accidents.

What this means for an injured worker: these rules give the rescue a measuring stick. If the vessel was covered, a review can ask whether drills and assigned duties existed and how the response on board compared with them, which can bear on a claim about the vessel's condition or the employer's conduct, and so on compensation. If the vessel was not covered, this measuring stick is not available. Neither rule, standing alone, says whether a particular rescue was carried out well.

Will the Fall Be Reported to the Coast Guard?

Under 46 C.F.R. § 4.05-1, paragraph (a), "immediately after addressing resultant safety concerns, the owner, agent, master, operator, or person in charge, must notify the nearest Coast Guard units" when a covered vessel, floating OCS facility or MODU is involved in a marine casualty consisting of any of a listed set of events. Among them are a loss of life, and "an injury that requires professional medical treatment (treatment beyond first aid) and, if the person is engaged or employed on board a vessel in commercial service... that renders the individual unfit to perform their routine duties." The list also includes an occurrence materially and adversely affecting seaworthiness, including failure of or damage to lifesaving equipment, along with groundings, propulsion and steering losses, major property damage and significant environmental harm.

A written report follows. 46 C.F.R. § 4.05-10 provides that the same responsible persons "must, within 5 days, file a written report of any marine casualty required to be reported under § 4.05-1," on Form CG-2692, supplemented as needed by addenda, including a Personnel Casualty Addendum and an Involved Persons and Witnesses Addendum.

46 C.F.R. § 4.01-3 removes certain vessels and situations from these requirements, including some deaths or injuries of shipyard or harbor workers that are subject to OSHA reporting rules instead, and public vessels except as another subpart provides.

What this means for an injured worker: the written report is often the earliest official account of the fall, naming who was involved, who saw it, and how the injury was described in the vessel's own words. That account can shape how a later claim is understood. Whether a report was or was not filed is a fact; on its own, it does not establish fault.

Which Claims May Fit a Worker Who Fell Overboard?

The first question is who the injured person was. Worker status and waterway facts control the route, and not every offshore worker is a Jones Act seaman. Some maritime workers fall under other frameworks, as our pages on offshore worker injuries and longshore work explain.

For a seaman, the Jones Act is the main negligence remedy. 46 U.S.C. § 30104, subsection (a), provides that "a seaman injured in the course of employment or, if the seaman dies from the injury, the personal representative of the seaman may elect to bring a civil action at law, with the right of trial by jury, against the employer." The same subsection applies the federal laws for injured railway workers to these actions. One of those laws, 45 U.S.C. § 53, says an employee's own contributory negligence "shall not bar a recovery," though damages are reduced in proportion to the employee's share, and that no such reduction applies where the employer's violation of a safety statute contributed to the injury or death. In plain terms, a worker who was partly at fault in the fall is not automatically shut out. A Jones Act negligence claim asks about a duty, a breach of it, causation and damages.

The second framework is unseaworthiness, from general maritime law. In Mitchell v. Trawler Racer, Inc., 362 U.S. 539 (1960), the Supreme Court described the owner's duty as furnishing a vessel and appurtenances reasonably fit for their intended use. In a fall overboard, that question can reach the vessel's rails, deck surfaces, lifesaving gear and crewing, and whether a condition caused the injury.

Third, maintenance and cure is a separate remedy of general maritime law tied to a seaman's employment, concerned with living costs and medical care while the seaman recovers. It stands apart from any claim about fault.

Timing is set federally. 46 U.S.C. § 30106 provides that, "except as otherwise provided by law," a civil action for personal injury or death arising out of a maritime tort "must be brought within 3 years after the cause of action arose."

These are different questions with different proof: the worker's job on the vessel, the vessel's condition and the employer's response all bear on which claim fits. Our page on the Jones Act lawyer question goes further into seaman status.

Which Records Matter After a Fall Overboard?

The Coast Guard notice and written casualty report are often the first official documents. On covered fishing and towing vessels, records of drills, instruction and assigned duty stations may also exist.

For someone who was hurt, the records that usually matter include:

• the written casualty report and any addenda listing involved persons and witnesses;
• drill logs, instruction records and emergency duty assignments, where the vessel was subject to those rules;
• inspection or maintenance records for rails, lifesaving equipment and recovery gear;
• the timeline of the response on board, from the alarm to the recovery;
• medical records from the first treatment onward;
• the names and accounts of crew who saw the fall or the rescue.

One limit is easy to miss. The Coast Guard may investigate a marine casualty, but 46 C.F.R. § 4.07-1, paragraph (b), states that those investigations are "for the purpose of taking appropriate measures for promoting safety of life and property at sea, and are not intended to fix civil or criminal responsibility." And under 46 U.S.C. § 6308, subsection (a), no part of a report of a marine casualty investigation conducted under section 6301, "including findings of fact, opinions, recommendations, deliberations, or conclusions, shall be admissible as evidence or subject to discovery" in civil proceedings, other than an administrative proceeding initiated by the United States.

That means the vessel's own records and the people who were there often carry more weight than a family expects, along with whether the gear involved was kept. Federal law also protects a seaman's job when speaking up: 46 U.S.C. § 2114 bars discharging or discriminating against a seaman for, among other things, notifying the vessel owner or the Secretary of a work-related injury or cooperating with a safety investigation. To talk through which records may bear on a particular fall, a case evaluation is available.

Key Questions That Shape a Man Overboard Claim

Was the injured person a seaman? The Jones Act action in 46 U.S.C. § 30104(a) belongs to seamen, so status is a threshold question. A deckhand, a fisherman, a platform worker and a dock worker may each end up on a different legal path after the same kind of fall. Our page on vessel deck fall injuries shows how status changes the route.

What vessel was it, and which rules covered it? The monthly drill rule reaches only the fishing vessels 46 C.F.R. § 28.200 names; the person-overboard duty rule reaches only the towing vessels 46 C.F.R. § 140.405(b) describes. A rule that did not apply to a vessel cannot be measured against it.

Was a Coast Guard report filed, and what does it record? The written report may list witnesses and describe the injury in the vessel's own words.

What does the record show about the rescue itself: the lifesaving equipment, the drills and the response on board? These questions concern conditions and conduct; none assumes that anything went wrong. Together, the answers shape which claim fits and what it would need to show.
