Definition
In admiralty law and marine insurance, bilged describes the condition of a vessel in which water enters freely through holes or breaches in the planks of the hull bottom caused by damage or injury — regardless of whether the ship's structural timbers are broken. The term denotes a specific and serious state of hull compromise: not merely leaking, but sufficiently breached at the bottom that water ingress is unimpeded.
The focus is on the planking of the bottom, not the vessel's frame. A ship may be bilged without its ribs or beams being fractured; the defining characteristic is the opening in the hull skin at or near the waterline or below, allowing free admission of water.
Common Language
Modern common usage (Wiktionary): Simple past and past participle of the verb "bilge" — to bilge a vessel, or for a vessel to bilge.
Historical common usage (Webster's 1913): Webster's defined "bilge" primarily as a noun referring to the broadest part of a ship's bottom, or the foul water that collects there; the verb form carried the sense of springing a leak or staving in the bottom.
The gap matters in insurance and admiralty contexts. In ordinary nautical language, "bilge" can refer to the lowest interior part of a hull where water collects in normal operation. In legal usage, "bilged" is a condition of liability-triggering hull damage — a term of art describing a specific casualty state, not routine water accumulation. A researcher encountering "bilged" in a policy dispute or salvage proceeding should read it as a finding of hull breach, not merely the presence of bilge water.
Common Confusion
"Bilged" should not be confused with ordinary bilge water accumulation, which is a normal feature of vessel operation. The legal definition requires that water be admitted freely through damage-caused openings in the hull planking. A ship that is pumping routine bilge water is not "bilged" in the legal sense. Similarly, "bilged" is distinct from "foundered" (sunk) or "stranded" (grounded) — though a bilged vessel may ultimately founder. In marine insurance claims, the distinction bears on which peril clause applies.
Why It Matters in Research
Bilged is a narrow admiralty term of art that appears most frequently in two research contexts: marine insurance coverage disputes and salvage proceedings. In both, whether a vessel was bilged — and when — can determine the scope of underwriter liability or the rights of salvors.
Researchers working in historical insurance law should note that the term appears with some frequency in nineteenth-century American admiralty opinions and policy interpretation cases. The foundational reference in the historical dictionaries — Peele v. Insurance Co., 3 Mason 27 (C.C.D. Mass. 1820) — is a genuine circuit court opinion by Justice Story sitting on circuit, and it remains the primary judicial authority behind the standard dictionary definition. Researchers seeking the doctrinal origin of this definition should go directly to that case.
The term will appear in policies, surveys, and protest documents. In marine surveys and ship's protests (sworn statements by masters following a casualty), "bilged" has both a technical and a legal meaning that often align, but researchers should be attentive to context: a surveyor's use of the term describes physical condition; a court's use determines legal consequence.
Because the definition has remained essentially static across all major legal dictionaries, there is little risk of definitional shift across time periods within the nineteenth and early twentieth century corpus. A researcher encountering the term in an 1830 insurance dispute and a 1910 salvage case can apply the same operative definition.
Historical Dictionary Support
All four source dictionaries — Black's (1st and 2nd editions), Bouvier's, and Anderson's — reproduce the same substantive definition with minimal variation: water freely admitted through damage-caused holes in the bottom planking, irrespective of timber integrity. This is notable uniformity, reflecting a settled term with a single authoritative source: the Peele decision.
Black's 2nd edition is the most useful of the four for research purposes because it provides the full citation to Peele v. Insurance Co., identifying it as 3 Mason 27, 39, 19 Fed. Cas. 103 — enabling direct retrieval. The 1st edition and Bouvier's cite only "3 Mass. 39," which is an abbreviated and potentially misleading citation that could be confused with Massachusetts Reports; the correct reporter is Mason's Circuit Court Reports. Anderson's omits the citation entirely. Researchers relying on the abbreviated form should not search Massachusetts state court reporters.
No source dictionary provides any elaboration on how courts distinguished degrees of bilging, which policy perils it triggered, or how it interacted with seaworthiness warranties — limitations that make primary source research in admiralty opinions essential for any substantive question.
Jurisdictional Note
Bilged is a term of federal admiralty and maritime law in the United States, with parallels in English maritime law from which American doctrine largely derived. Substantive marine insurance law in the U.S. has historically followed English precedent closely, particularly Lloyd's practice. Researchers working in state court insurance cases involving marine policies should confirm whether the forum applied federal admiralty principles or state contract law, as this affects how casualty terms were interpreted.
