Justice Marshall
delivered the opinion of the Court.
The issue presented in this case is whether the collision of two pleasure boats on navigable waters falls within the admiralty jurisdiction of the federal courts. See 28 U. S. C. § 1333. We granted certiorari to resolve the confusion in the lower courts respecting the impact of Executive Jet Aviation, Inc. v. City of Cleveland, 409 U. S. 249 (1972), on traditional rules for determining federal admiralty jurisdiction. 454 U. S. 813 (1981). The United States Court of Appeals for the Fifth Circuit held that an accident between two vessels in navigable waters bears a sufficient relationship to traditional maritime activity to fall within federal admiralty jurisdiction. We affirm.
I
Two pleasure boats collided on the Amite River in Louisiana, resulting in the death of Clyde Richardson. The wife and children of the decedent brought this action in the United States District Court for the Middle District of Louisiana, alleging, inter alia, that petitioner Shirley Eliser had negligently operated the boat that collided with the vessel occupied by the decedent. Respondents also named petitioner Foremost Insurance Co., Eliser’s insurer, as a defendant. Jurisdiction was claimed under 28 U. S. C. § 1333(1), which gives federal district courts exclusive jurisdiction over “[a]ny civil case of admiralty or maritime jurisdiction.” Petitioners moved to dismiss, arguing that the complaint did not state a cause of action within the admiralty or maritime jurisdiction of the District Court.
In ruling on petitioners’ motion, the District Court found the following facts to be undisputed:
“(i) One boat was used for pleasure boating, such as boat riding and water skiing, and at the time of the accident the boat was actually pulling a skier on a zip sled;
“(2) The other boat was used exclusively for pleasure fishing and was described as a bass boat;
“(3) Neither boat had ever been used in any ‘commercial maritime activity’ before the accident;
“(4) At the time of the accident neither boat was involved in any ‘commercial maritime activity’ of any sort;
“(5) Neither of the two drivers of the boat were being paid to operate the boat nor was this activity in any way a part of their regular type of employment;
“(6) None of the passengers on either boat were engaged in any kind of ‘traditional maritime activity’ either before or at the time of the accident;
“(7) Neither of the boats involved were under hire in any traditional maritime form;
“(8) There is no evidence to indicate that any ‘commercial activity’, even in the broadest admiralty sense, had ever been previously engaged in by either of the boats in question, and in fact the two boats would have to be classified as ‘purely pleasure craft’, not in any way ‘involved in commerce’, and,
“(9) There was no other instrumentality involved in this accident that had even a minor relationship to ‘admiralty’ or ‘commerce’, i. e. a buoy, barge, oil drilling apparatus, etc.” 470 F. Supp. 699, 700 (1979).
After reviewing decisions of this Court and the Fifth Circuit, as well as relevant commentary, the District Court found that there must be some relationship with traditional maritime activity for an injury sustained on navigable water to fall within federal admiralty jurisdiction. The District Court held that commercial maritime activity is necessary to satisfy this relationship, and granted petitioners’ motion to dismiss the complaint for lack of subject-matter jurisdiction because the collision of these two pleasure boats did not involve any commercial activity.
The Court of Appeals reversed. 641 F. 2d 314 (1981). The Court of Appeals agreed that Executive Jet, supra, and relevant Fifth Circuit decisions establish that “admiralty jurisdiction requires more than the occurrence of the tort on navigable waters — that additionally there must be a significant relationship between the wrong and traditional maritime activity.” 641 F. 2d, at 315. It disagreed with the District Court, however, on the application of this principle to the undisputed facts of this case. Relying on the fact that the “Rules of the Road” govern all boats on navigable waters, and on the uncertainty that would accompany a finding of no admiralty jurisdiction in this case, the Court of Appeals held that “two boats, regardless of their intended use, purpose, size, and activity, are engaged in traditional maritime activity when a collision between them occurs on navigable waters.” Id., at 316.

Prior to our opinion in Executive Jet, there, was little question that a complaint such as the one filed here stated a cause of action within federal admiralty jurisdiction. Indeed, the Executive Jet Court begins its opinion by observing that, under the traditional rule of admiralty jurisdiction, “[i]f the wrong occurred on navigable waters, the action is within admiralty jurisdiction.” 409 U. S., at 253 (citing Thomas v. Lane, 23 F. Cas. 957, 960 (No. 13,902) (CC Me. 1813) (Story, J., on Circuit). See also The Plymouth, 3 Wall. 20, 36 (1866) (“Every species of tort, however occurring, and whether on board a vessel or not, if upon the high seas or navigable waters, is of admiralty cognizance”). Under this rule, an action arising out of a collision between two pleasure boats on navigable waters clearly falls within the admiralty jurisdiction of the district courts. When presented with this precise situation in the past, this Court has found it unnecessary even to discuss whether the district court’s admiralty jurisdiction had been properly invoked, instead assuming the propriety of such jurisdiction merely because the accident occurred on navigable waters. Levinson v. Deupree, 345 U. S. 648, 651 (1953). See also Just v. Chambers, 312 U. S. 383 (1941) (injury to guest from carbon monoxide poisoning in the cabin of a pleasure boat). Cf. Coryell v. Phipps, 317 U. S. 406 (1943). In light of these decisions, we address here only the narrow question whether Executive Jet disapproved these earlier decisions sub silentio.
In Executive Jet, this Court held that a suit for property damage to a jet aircraft that struck a flock of sea gulls upon takeoff and sank in the navigable-waters of Lake Erie did not state a claim within the admiralty jurisdiction of the district courts. In reaching this conclusion, the Court observed that the mechanical application of the locality rule as the sole test for determining whether there is admiralty jurisdiction had been widely criticized by commentators, and that the federal courts and Congress had been compelled to make exceptions to this approach in the interests of justice in order to include certain torts with no maritime locality. The Court determined that claims arising from airplane accidents are cognizable in admiralty only when the wrong bears a significant relationship to traditional maritime activity. 409 U. S., at 268. Given the realities of modern-day air travel, the Executive Jet Court held that, “in the absence of legislation to the contrary, there is no federal admiralty jurisdiction over aviation tort claims arising from flights by land-based aircraft between points within the continental United States.” Id., at 274.
The express holding of Executive Jet is carefully limited to the particular facts of that case. However, the thorough discussion of the theoretical and practical problems inherent in broadly applying the traditional locality rule has prompted several courts and commentators to construe Executive Jet as applying to determinations of federal admiralty jurisdiction outside the context of aviation torts. See, e. g., Kelly v. Smith, 485 F. 2d 520 (CA5 1973); Calamari, The Wake of Executive Jet — A Major Wave or a Minor Ripple, 4 Maritime Law. 52 (1979). We believe that this is a fair construction. Although Executive Jet addressed only the unique problems associated with extending admiralty jurisdiction to aviation torts, much of the Court’s rationale in rejecting a strict locality rule also applies to the maritime context. Indeed, the Executive Jet Court relied extensively on admiralty and maritime decisions of this Court and on congressional action extending admiralty jurisdiction to torts with a significant relationship to traditional maritime activity, but with no maritime locality.
We recognize, as did the Court of Appeals, that the Executive Jet requirement that the wrong have a significant connection with traditional maritime activity is not limited to the aviation context. We also agree that there is no requirement that “the maritime activity be an exclusively commercial one.” 641 F. 2d, at 316. Because the “wrong” here involves the negligent operation of a vessel on navigable waters, we believe that it has a sufficient nexus to traditional maritime activity to sustain admiralty jurisdiction in the District Court.
We are not persuaded by petitioners’ argument that a substantial relationship with commercial maritime activity is necessary because commercial shipping is at the heart of the traditional maritime activity sought to be protected by giving the federal courts exclusive jurisdiction over all admiralty suits. This argument is premised on the faulty assumption that, absent this relationship with commercial activity, the need for uniform rules to govern conduct and liability disappears, and “federalism” concerns dictate that these torts be litigated in the state courts.
Although the primary focus of admiralty jurisdiction is unquestionably the protection of maritime commerce, petitioners take too narrow a view of the federal interest sought to be protected. The federal interest in protecting maritime commerce cannot be adequately served if admiralty jurisdiction is restricted to those individuals actually engaged in commercial maritime activity. This interest can be fully vindicated only if all operators of vessels on navigable waters are subject to uniform rules of conduct. The failure to recognize the breadth of this federal interest ignores the potential effect of noncommercial maritime activity on maritime commerce. For example, if these two boats collided at the mouth of the St. Lawrence Seaway, there would be a substantial effect on maritime commerce, without regard to whether either boat was actively, or had been previously, engaged in commercial activity. Furthermore, admiralty law has traditionally been concerned with the conduct alleged to have caused this collision by virtue of its “navigational rules — rules that govern the manner and direction those vessels may rightly move upon the waters.” Executive Jet, 409 U. S., at 270. The potential disruptive impact of a collision between boats on navigable waters, when coupled with the traditional concern that admiralty law holds for navigation, compels the conclusion that this collision between two pleasure boats on navigable waters has a significant relationship with maritime commerce.
Yet, under the strict commercial rule proffered by petitioners, the status of the boats as “pleasure” boats, as opposed to “commercial” boats, would control the existence of admiralty jurisdiction. Application of this rule, however, leads to inconsistent findings or denials of admiralty jurisdiction similar to those found fatal to the locality rule in Executive Jet. Under the commercial rule, fortuitous circumstances such as whether the boat was, or had ever been, rented, or whether it had ever been used for commercial fishing, control the existence of federal-court jurisdiction. The owner of a vessel used for both business and pleasure might be subject to radically different rules of liability depending upon whether his activity at the time of a collision is found by the court ultimately assuming jurisdiction over the controversy to have been sufficiently “commercial.” We decline to inject the uncertainty inherent in such line-drawing into maritime transportation. Moreover, the smooth flow of maritime commerce is promoted when all vessel operators are subject to the same duties and liabilities. Adopting the strict commercial rule would frustrate the goal of promoting the smooth flow of maritime commerce, because the duties and obligations of noncommercial navigators traversing navigable waters flowing through more than one State would differ “depending upon their precise location within the territorial jurisdiction of one state or another.” 641 F. 2d, at 316.
Finally, our interpretation is consistent with congressional activity in this area. First, Congress defines the term “vessel,” for the purpose of determining the scope of various shipping and maritime transportation laws, to include all types of waterborne vessels, without regard to whether they engage in commercial activity. See, e. g., 1 U. S. C. §3 (“‘vessel’ includes every description of watercraft or other artificial contrivance used, or capable of being used, as a means of transportation on water”). Second, the federal “Rules of the Road,” designed for preventing collisions on navigable waters, see, e. g., 94 Stat. 3415,33 U. S. C. § 2001 et seq. (1976 ed., Supp. IV), apply to all vessels without regard to their commercial or noncommercial nature. Third, when it extended admiralty jurisdiction to injuries on land caused by ships on navigable waters, Congress directed that “[t]he admiralty and maritime jurisdiction of the United States shall extend to and include all cases of damage or injury . . caused by a vessel on navigable water. ...” Extension of Admiralty Jurisdiction Act, 62 Stat. 496, 46 U. S. C. § 740.
In light of the need for uniform rules governing navigation, the potential impact on maritime commerce when two vessels collide on navigable waters, and the uncertainty and confusion that would necessarily accompany a jurisdictional test tied to the commercial use of a given boat, we hold that a complaint alleging a collision between two vessels on navigable waters properly states a claim within the admiralty jurisdiction of the federal courts. Therefore, the judgment of the Court of Appeals is
Affirmed.
The wife and children of the decedent also named respondent June Allen as a defendant. They alleged that Allen was operating the vessel at the time of the collision, and that the decedent’s death was caused by either the negligence of Allen or that of petitioner Eliser. Allen counterclaimed, alleging that the decedent had been operating the boat, and that her injuries were caused by his negligence. The factual dispute concerning whether the decedent or Allen was operating the boat is irrelevant to the jurisdictional issue. However, because of the divergent interests and claims of respondent Allen and the respondent family of the decedent below, we refer only to the decedent’s family when we use the term “respondents” throughout this opinion.
The District Court assumed that the Amite River is navigable at the site of the collision. Although the issue is not free from doubt, it appears from the opinion and the disposition of the Court of Appeals that the court found that the river is navigable at this site although seldom, if ever, used for commercial traffic. This opinion is premised on our understanding that the river at this point is navigable, see Brief for Petitioners 20, but we leave open the question whether petitioners have preserved the opportunity to argue this issue upon further development of facts in the District Court.
Judge Thornberry, concurring in part and dissenting in part, argued that federal admiralty jurisdiction could not be sustained if the river at the site of the accident, although navigable, did not also function as an integral or major “artery of commerce.” 641 F. 2d, at 317.
In addition to noting these examples where strict application of the locality rule would have deprived the courts of admiralty jurisdiction despite a clear connection to maritime activity, the Court noted the difficulties of extending jurisdiction to torts with a maritime locality, but absolutely no connection to maritime activity. See 409 U. S., at 255-256 (disapproving decisions sustaining admiralty jurisdiction over claims by swimmers injured by other swimmers or submerged objects in shallow waters near shore); id., at 256-257 (approving decisions requiring some connection with traditional maritime activity).
Not every accident in navigable waters that might disrupt maritime commerce will support federal admiralty jurisdiction. In Executive Jet, for example, we concluded that the sinking of the plane in navigable waters did not give rise to a claim in admiralty even though an aircraft sinking in the water could create a hazard for the navigation of commercial vessels in the vicinity. However, when this kind of potential hazard to maritime commerce arises out of activity that bears a substantial relationship to traditional maritime activity, as does the navigation of the boats in this case, admiralty jurisdiction is appropriate.
Petitioners argue that admiralty jurisdiction in the federal courts is unnecessary to ensure the uniform application of the Rules of the Road to boat navigation because state courts are bound by the construction federal courts give to statutes relating to navigation. Assuming that petitioners are correct, this fact does not negate the importance that Congress has attached to the federal interest in having all vessels operating on navigable waters governed by uniform rules and obligations, which is furthered by consistent application of federal maritime legislation under federal admiralty jurisdiction.
We refer to this language only to demonstrate that Congress did not require a commercial-activity nexus when it extended admiralty jurisdiction. We express no opinion on whether this Act could be construed to provide an independent basis for jurisdiction.
