Definition
A charge or tribute levied on a vessel for the privilege of occupying a berth, anchorage, or space within a port. Groundage is a form of maritime toll paid by shipowners or masters to the port authority or local sovereign in exchange for the use of harbor ground while the vessel remains in port. It is distinct from pilotage, towage, or wharfage, though all may be collected together as port dues.

Common Language
Modern common usage (Wiktionary): "A local tax paid by a ship for the ground or space it occupies while in port."
Historical common usage (Webster's 1913): "A local tax paid by a ship for the ground or space it occupies while in port."
The common and legal definitions align closely here, which is unusual for a maritime term. The slight distinction worth noting for researchers: legal sources frame groundage as a custom or tribute with ancient common-law roots, not merely a modern regulatory charge. The word "custom" in the historical legal definitions carries technical weight — it signals a toll of immemorial usage enforceable as a matter of right, not merely a contractual fee or statutory imposition.

Why It Matters in Research
Groundage is a narrow but historically durable term in maritime and port law. Researchers will encounter it most frequently in English admiralty materials, port charter documents, and customs records from the medieval through early modern period. It appears less frequently in American legal sources, where port charges were more often governed by statute or tariff schedules and labeled differently.
Several navigational traps await the researcher:
First, the term appears in close proximity to entries on GROWING CROPS in Rapalje & Lawrence — a placement artifact that has caused misattribution in some secondary indices. The groundage entry ends and the growing crops entry begins without a clean break, so researchers pulling partial quotes should verify the boundary of the entry.
Second, groundage is frequently grouped with wharfage and anchorage in older port instruments. These are legally distinct obligations: wharfage attaches to the use of a wharf structure; anchorage to the use of anchoring ground; groundage to the mere occupancy of port space. Conflating them in a historical document search will return over-inclusive results.
Third, the characterization of groundage as a "custom" rather than a statutory charge means that historical disputes over its validity often appear in common-law courts rather than admiralty courts, depending on the period and jurisdiction. Researchers should cast their search net accordingly.
American corpus materials on groundage are sparse. The concept was absorbed into broader port fee and harbor dues frameworks in U.S. practice, and the specific term largely fell out of American legal usage by the nineteenth century. English and Commonwealth sources are the primary research locus.

Historical Dictionary Support
All four historical dictionaries converge on the same core definition: a charge paid for the standing of a ship in port. Bouvier frames it explicitly as a maritime law concept and cites Jacob's Law Dictionary as authority, a citation echoed by both Black's editions and Rapalje & Lawrence — indicating that Jacob was the common root source for this entry across the American legal dictionary tradition.
None of the historical dictionaries address the enforcement mechanism, the identity of the collecting authority, or the procedural posture in which groundage disputes arose. This is a gap worth flagging: the dictionaries treat groundage descriptively but offer no guidance on how a claim for unpaid groundage was pursued or whether it gave rise to a maritime lien. Researchers needing that procedural dimension must look beyond the dictionary shelf to English admiralty records and port charter instruments.
Rapalje & Lawrence is the only source that uses the word "custom" without also using "tribute," while Black's and Bouvier use both. The distinction may reflect nothing more than editorial compression, but "custom" standing alone signals the common-law enforcement character of the charge more clearly.

Jurisdictional Note
Groundage as a named legal charge is primarily an English and Commonwealth concept. In the United States, equivalent charges were typically codified under harbor or port tariff statutes and are not generally labeled groundage in American case law or regulatory materials. Researchers working in U.S. admiralty contexts should cross-reference anchorage fees and port dues rather than searching groundage directly.
