Definition
A term from French commercial law denoting the collision of vessels at sea. Abordage describes the event in which one ship strikes or comes into injurious contact with another, giving rise to questions of liability, fault, and compensation under maritime law. The term is French in origin and appears in English-language legal sources primarily as a borrowing from civil law admiralty practice, most often in treatises and cases engaging with French or civilian maritime authorities.
Common Language
Modern common usage (Wiktionary): "The act of boarding a ship as part of an attack."
Historical common usage (Webster's 1913): Not separately defined; the root sense in French carries both the meaning of coming alongside a vessel and of boarding it forcibly.
The gap here is meaningful and potentially misleading. In ordinary usage, abordage suggests a hostile boarding action — pirates or naval forces seizing a vessel. In French commercial and maritime law, the term was repurposed to describe accidental collision between ships, a purely civil and tortious concept with no element of aggression. A researcher encountering the word in a legal source should not read the common military or nautical sense into it.
Common Confusion
Abordage is sometimes loosely treated as synonymous with the English term collision in maritime contexts, but the two are not interchangeable in their native legal registers. Collision is the standard English admiralty term and carries a developed body of Anglo-American case law and statutory treatment. Abordage is the civilian counterpart, functioning within the French commercial law tradition. In English-language legal dictionaries, abordage appears almost exclusively as a term of art requiring translation to the civilian framework — it does not import English admiralty doctrine wholesale. Researchers should also distinguish abordage from allision, the English admiralty term specifically describing a moving vessel striking a stationary object such as a dock or anchored ship.
Why It Matters in Research
Abordage is a narrow term of art that surfaces primarily in three research contexts: (1) treatises engaging with French or continental maritime law, (2) comparative admiralty scholarship, and (3) older American and English cases or commentary drawing on civilian sources to fill gaps in common law admiralty doctrine.
The most important navigational point for corpus researchers is that the term is almost never used in American or English judicial opinions as operative language — courts writing in English use collision or allision. When abordage appears in an English-language legal text, it almost always signals the author is citing or synthesizing French authority, not applying domestic doctrine directly. Follow the citation trail into the civilian treatise literature, particularly Emerigon, who is the authority both Black's and Burrill cite in connection with this term.
Researchers working in pre-twentieth-century admiralty sources should be alert to the fact that the civilian doctrine of abordage and the English admiralty rules on collision did not always align, particularly on questions of proportional fault. French law and early civilian practice sometimes distributed loss differently than English admiralty, which for much of the nineteenth century applied a rule of equal division of damages in cases of mutual fault. This divergence can affect how a historical source frames liability analysis.
Historical Dictionary Support
The three source dictionaries are in close agreement: all three define abordage as a French commercial law term meaning collision of vessels, and none ventures beyond that minimal definition. Black's first and second editions are nearly identical. Burrill adds the only substantive value by citing Emerigon's Traité des Assurances, chapter 12, section 14 — the only primary authority named across all three entries and a genuine anchor for further research into the civilian treatment of maritime collision.
What the historical dictionaries do not provide is any doctrinal content: no elements of fault, no discussion of how liability was apportioned, no indication of how abordage doctrine differed from English admiralty practice. They function purely as translation entries, alerting the common law reader that a French term is being used and identifying its subject matter. Researchers seeking the substance of the doctrine must go to Emerigon directly or to secondary maritime law treatises that engage with civilian sources.
Jurisdictional Note
Abordage as a legal term has no operative role in current American or English admiralty law. It appears as a historical and comparative reference. Louisiana, with its civil law tradition, offers the closest domestic analog in terms of civilian influence, but even Louisiana admiralty practice follows federal maritime law for collision matters. The term is most alive in French and francophone maritime legal systems.
