If you were hurt aboard a vessel in a collision, allision or grounding, federal maritime law usually decides who may be answerable. The possible parties include your own vessel's owner or employer, the other vessel and a licensed officer. A vessel owner may try to cap its liability, and federal investigations often follow, though they do not decide legal fault.

Most people facing this are crew members or maritime workers who were thrown, crushed or knocked overboard in a moment of impact, or families whose person did not come home from the job. On top of injuries and lost wages, the questions arrive fast: Coast Guard officers asking for statements, an owner's lawyers sending papers from federal court, and no clear sense of whose fault anything was. This page walks through the rules that shape those questions, one at a time, in plain words.

What a Vessel Collision Is Under Federal Maritime Law

The federal regulations treat a crash at sea as a marine casualty, a defined term for the events the Coast Guard tracks and investigates. Under 46 C.F.R. § 4.03-1, "marine casualty or accident" applies to events "including, but not limited to" a fall overboard, injury or loss of life, grounding, stranding, foundering, flooding, collision, allision, explosion, fire, loss of power, propulsion or steering, and other listed occurrences. The definition reaches casualties on the navigable waters of the United States and those involving a U.S. vessel wherever they happen, along with certain foreign tank vessel and offshore situations the text describes.

Three of those words cover most crashes. A collision is two vessels striking each other. An allision is a vessel striking something that does not move, such as a bridge, a pier or a moored vessel; the regulations themselves describe "an unintended strike of (allision with) a bridge" in 46 C.F.R. § 4.05-1. A grounding is a vessel running onto the bottom.

This page is about crew and workers aboard working vessels such as tugboats and towing vessels or cargo ships. Crashes between recreational boats, yachts and jet skis are a different subject, where maritime jurisdiction is fact-specific and many incidents are governed by state law.

Which law applies to an injury depends on the facts: where the injury happened, the vessel, the waters and the injured person's status. That single point runs underneath everything that follows, so it is worth holding onto as you read.

Who May Be Answerable When a Collision Injures a Worker

Federal law names one group of people directly. Under 46 U.S.C. § 30103, "A person may bring a civil action against a master, mate, engineer, or pilot of a vessel, and recover damages, for personal injury or loss caused by" that officer's "(1) negligence or willful misconduct; or (2) neglect or refusal to obey the laws governing the navigation of vessels."

In plain terms, the individual conduct of a ship's officer, not only the owner's, can be the basis of a civil claim. For an injured worker, that means the person on the bridge or in the engine room at the moment of impact is part of the legal picture, not just the company whose name is on the hull.

The other parties usually come from the vessels themselves:

  • The owner or operator of the worker's own vessel, which is often also the employer.
  • The other vessel, and its owner or operator, when a second vessel was involved.
  • A licensed officer on either vessel, including a pilot, as the statute above describes.

A single crash can involve more than one of these at once, and each sits in a different legal relationship to the injured person. Whether any of them is legally responsible depends on the facts and the law that applies; an injury alone does not establish anyone's fault. Someone in this position may want to think about which vessels were involved, who owned and crewed each one, and who was giving the orders when it happened.

How a Vessel Owner Can Seek to Limit Liability — and What That Means for Your Claim

Federal law gives vessel owners a tool that has no close match in an ordinary accident case: limitation of liability, a request to cap what the owner can owe. Under 46 U.S.C. § 30523, "Except as provided in section 30524 of this title, the liability of the owner of a vessel" for covered claims "shall not exceed the value of the vessel and pending freight." Covered claims include "any loss, damage, or injury by collision," and any loss or damage "done, occasioned, or incurred, without the privity or knowledge of the owner," unless otherwise excluded by law. The cap is therefore a general rule, subject to the section 30524 exception, and it does not apply to a claim for wages. Where a vessel has several owners, each owner's share is capped at that owner's proportionate interest.

"Value of the vessel and pending freight" means, practically, that the owner asks a court to treat the vessel itself, plus the freight money then due for its voyage, as the outer limit of what is available. The exception in section 30524 sits alongside that rule, and so does the "privity or knowledge" language, which ties limitation to what the owner knew or took part in.

The owner's filing has its own clock. Under 46 U.S.C. § 30529, the owner "may bring a civil action in a district court of the United States for limitation of liability," and "The action must be brought within 6 months after a claimant gives the owner written notice of a claim." Once the action is brought and the owner has complied with the statute's requirement to deposit or transfer a fund for claimants, "all claims and proceedings against the owner related to the matter in question shall cease," which is why claims against the owner generally then move into that federal case.

For an injured worker or family, this can mean a lawsuit filed elsewhere is halted, and the questions shift to a federal courtroom. Whether an owner's request to limit succeeds is a separate question that depends on the facts and the law; the filing itself decides nothing. A family that receives limitation papers may want to weigh when written notice of the claim was given and what the federal court's notice asks of claimants.

The Investigations That Follow a Vessel Collision

Two federal tracks usually open after a serious crash, and neither one is a lawsuit. The first belongs to the Coast Guard. Because collisions, allisions and groundings fall within the marine casualty definition above, the owner, agent, master, operator or person in charge must notify the nearest Coast Guard unit "immediately after addressing resultant safety concerns" for listed casualties, including a loss of life or "An injury that requires professional medical treatment (treatment beyond first aid)" that, for a person employed aboard a vessel in commercial service, leaves the person unfit for routine duties, under 46 C.F.R. § 4.05-1. A written report on Form CG-2692 must follow "within 5 days," with addenda that include a personnel casualty addendum and an involved persons and witnesses addendum, under 46 C.F.R. § 4.05-10.

The second track belongs to the National Transportation Safety Board. Under 49 U.S.C. § 1131(a)(1)(E), the Board "shall investigate or have investigated" and establish "the facts, circumstances, and cause or probable cause of" a major marine casualty (except one involving only public vessels) in United States waters or involving a U.S. vessel. According to the NTSB's Office of Marine Safety, the US Coast Guard "conducts preliminary investigations of all marine casualties and notifies the MS when an event qualifies as a major marine casualty." After investigating each major marine casualty, the office "releases an investigation report with a probable cause, which may include safety recommendations."

These reports are not verdicts. The Coast Guard's own rule, 46 C.F.R. § 4.07-1(b), says its investigations are for promoting safety "and are not intended to fix civil or criminal responsibility." Congress went further for Coast Guard reports: under 46 U.S.C. § 6308(a), "no part of a report of a marine casualty investigation conducted under section 6301 of this title, including findings of fact, opinions, recommendations, deliberations, or conclusions, shall be admissible as evidence or subject to discovery in any civil or administrative proceedings, other than an administrative proceeding initiated by the United States." That provision speaks to Coast Guard reports; a separate federal law likewise bars admitting any part of an NTSB accident report in a civil action for damages.

For a worker who was interviewed, this can feel strange: the official account may exist, yet it cannot simply carry a civil case. Seamen also have legal protection here. Under 46 U.S.C. § 2114, a person may not discharge or discriminate against a seaman because the seaman cooperated with a safety investigation by the Secretary or the NTSB, or furnished information about a marine casualty, among other listed reasons.

What Evidence Often Matters After a Collision at Sea

When the Coast Guard's report cannot be used in a civil case, the story of what happened has to be told through other records. Records that often bear on a vessel collision claim include:

  • Vessel logs, such as the deck and engine logs.
  • Voyage data recorder (VDR) or simplified voyage data recorder (S-VDR) data, where the vessel carries one.
  • AIS (Automatic Identification System) position records showing where vessels were and how they moved.
  • Coast Guard marine casualty reports and NTSB investigation reports, read with the limits described above in mind.
  • Crew and witness statements, including the names of everyone aboard each vessel.
  • Maintenance and inspection records for the steering, propulsion and navigation equipment.
  • The injured person's medical records, from first treatment aboard or ashore onward.

Some of these records sit with the injured person or the family: medical records, pay records, photos taken on a phone, and the names of crewmates. Others sit with vessel owners, operators and agencies. If you were hurt, knowing which records exist and who holds them is often the first step in understanding what can be shown about the crash.

Families after a death often find that the people who saw what happened are the crew who shared the watch. Their names and contact details tend to matter as much as any document.

An injured crew member's case rarely looks like a car crash claim, because federal statutes write much of the rulebook. The first is the Jones Act, 46 U.S.C. § 30104, under which "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." Whether someone is a seaman is a legal determination that turns on the facts.

That statute borrows the laws "regulating recovery for personal injury to, or death of, a railway employee." One of them, 45 U.S.C. § 53, provides that an employee's own contributory negligence "shall not bar a recovery, but the damages shall be diminished by the jury in proportion to the amount of negligence attributable to such employee," and that no contributory negligence is charged where the employer's violation of a safety statute contributed to the injury or death. A worker who worries that a split-second choice on deck ends everything may find that this rule frames fault differently than expected.

The general maritime law adds remedies of its own for injured seamen, including maintenance and cure, the employer's duty to provide a seaman injured in service with living expenses and medical care. Claims tied to unseaworthiness can also arise.

Workers who are not seamen may fall under the Longshore and Harbor Workers' Compensation Act, 33 U.S.C. § 901 et seq., a federal compensation system for certain maritime workers, covered further on the longshore worker injury page. Timing is federal too: under 46 U.S.C. § 30106, "Except as otherwise provided by law, a civil action for damages for personal injury or death arising out of a maritime tort must be brought within 3 years after the cause of action arose."

Worker status and the facts of the waterway decide which framework applies. A deckhand on a commercial fishing vessel, a harbor worker on a barge and a technician riding out to a platform can all be hurt in the same kind of crash and still land in different frameworks.

Questions Worth Asking Before You Speak With a Maritime Attorney

If you were injured in a vessel collision, the details that often shape the legal picture include:

  • The type of vessel you were aboard and the flag it flies.
  • The waters where it happened: navigable waters of the United States, the territorial sea, or the high seas.
  • Your employment status and your job duties aboard, and who paid you.
  • Whether a second vessel was involved, and who owned and operated it.
  • Whether a licensed master, mate, engineer or pilot was directing the vessel in the moments before impact.
  • What investigations are underway or completed, and whether you or a crewmate gave a statement.
  • What records you or your family already have, from medical records to written notices from an owner.

These details bear on which legal framework applies, who may be answerable and what remedies may be available. They also connect to the dates above: when an owner received written notice, and when the injury happened.

Many families reach this point holding a stack of papers and a list of half-answered questions. A conversation with our attorney can go through these details one by one and talk about which of them carry the most weight in a crash like yours; you can request a case evaluation when you are ready.

Frequently asked questions

What is the difference between a collision, an allision, and a grounding?

A collision is vessels striking each other, an allision is a vessel striking a fixed object such as a bridge, and a grounding is a vessel running onto the bottom. The regulation lists all three among marine casualties, so each can trigger Coast Guard reporting and investigation.

Can an injured worker sue the vessel's master or pilot directly?

Federal law allows a civil action against a master, mate, engineer or pilot for injury caused by their negligence, willful misconduct, or neglect or refusal to obey navigation laws. Whether a particular officer's conduct meets that standard depends on what happened at the helm and on the facts as a whole.

What does it mean when a vessel owner files to limit liability?

It means the owner has asked a federal district court to cap its liability at the value of the vessel and pending freight. Once that action is properly brought, related claims against the owner elsewhere cease, so the case gathers in one court. The filing does not itself decide the outcome.

Can the Coast Guard's investigation report be used in a civil lawsuit?

No part of a Coast Guard marine casualty investigation report, including its findings and conclusions, is admissible or subject to discovery in civil proceedings. The narrow exception is an administrative proceeding the United States starts. That is why logs, data and witnesses carry so much of a civil case.

What is the difference between the Jones Act and the Longshore and Harbor Workers' Compensation Act?

The Jones Act lets a seaman injured in the course of employment bring a jury-tried negligence action against the employer. The Longshore Act is a federal compensation system for certain maritime workers who are not seamen. The same crash can place two injured workers under different laws.

Does a government investigation determine who is legally at fault for a collision?

No. Coast Guard investigations are not intended to fix civil or criminal responsibility, and NTSB investigations determine probable cause with an eye to safety recommendations. Legal fault in a civil case is decided by a court on the evidence admitted there and the law that applies.
