Opinions

Justice O’Connor

delivered the opinion of the Court.

This case asks us to clarify what “employment-related connection to a vessel in navigation,” McDermott Int’l, Inc. v. Wilander, 498 U. S. 337, 355 (1991), is necessary for a maritime worker to qualify as a seaman under the Jones Act, 46 U. S. C. App. § 688(a). In Wilander, we addressed the type of activities that a seaman must perform and held that, under the Jones Act, a seaman’s job need not be limited to transportation-related functions that directly aid in the vessel’s navigation. We now determine what relationship a worker must have to the vessel, regardless of the specific tasks the worker undertakes, in order to obtain seaman status.

In May 1989, respondent Antonios Latsis was employed by petitioner Chandris, Inc., as a salaried superintendent engineer. Latsis was responsible for maintaining and updating the electronic and communications equipment on Chandris’ fleet of vessels, which consisted of six passenger cruise ships. Each ship in the Chandris fleet carried between 12 and 14 engineers who were assigned permanently to that vessel. Latsis, on the other hand, was one of two supervising engineers based at Chandris’ Miami office; his duties ran to the entire fleet and included not only overseeing the vessels’ engineering departments, which required him to take a number of voyages, but also planning and directing ship maintenance from the shore. Latsis claimed at trial that he spent 72 percent of his time at sea, App. 58; his immediate supervisor testified that the appropriate figure was closer to 10 percent, id., at 180.

On May 14, 1989, Latsis sailed for Bermuda aboard the S. S. Galileo to plan for an upcoming renovation of the ship, which was one of the older vessels in the Chandris fleet. Latsis developed a problem with his right eye on the day of departure, and he saw the ship’s doctor as the Galileo left port. The doctor diagnosed a suspected detached retina but failed to follow standard medical procedure, which would have been to direct Latsis to see an ophthalmologist on an emergency basis. Instead, the ship’s doctor recommended that Latsis relax until he could see an eye specialist when the Galileo arrived in Bermuda two days later. No attempt was made to transport Latsis ashore for prompt medical care by means of a pilot vessel or helicopter during the 11 hours it took the ship to reach the open sea from Baltimore, and Latsis received no further medical care until after the ship arrived in Bermuda. In Bermuda, a doctor diagnosed a detached retina and recommended immediate hospitalization and surgery. Although the operation was a partial success, Latsis lost 75 percent of his vision in his right eye.

Following his recuperation, which lasted approximately six weeks, Latsis resumed his duties with Chandris. On September 30,1989, he sailed with the Galileo to Bremerhaven, Germany, where the vessel was placed in drydock for a 6-month refurbishment. After the conversion, the company renamed the vessel the S. S. Meridian. Latsis, who had been with the ship the entire time it was in drydock in Bremerhaven, sailed back to the United States on board the Meridian and continued to work for Chandris until November 1990, when his employment was terminated for reasons that are not clear from the record.

In October 1991, Latsis filed suit in the United States District Court for the Southern District of New York seeking compensatory damages under the Jones Act, 46 U. S. C. App. § 688, for the negligence of the ship’s doctor that resulted in the significant loss of sight in Latsis’ right eye. The Jones Act provides, in pertinent part, that “[a]ny seaman who shall suffer personal injury in the course of his employment may, at his election, maintain an action for damages at law, with the right of trial by jury . . . .” The District Court instructed the jury that it could conclude that Latsis was a seaman within the meaning of the statute if it found as follows:

“[T]he plaintiff was either permanently assigned to the vessel or performed a substantial part of his work on the vessel. In determining whether Mr. Latsis performed a substantial part of his work on the vessel, you may not consider the period of time the Galileo was in drydock in Germany, because during that time period she was out of navigation. You may, however, consider the time spent sailing to and from Germany for the conversion. Also, on this first element of being a seaman, seamen do not include land-based workers.” App. 210.

The parties stipulated to the District Court’s second requirement for Jones Act coverage — that Latsis’ duties contributed to the accomplishment of the missions of the Chandris vessels. Id., at 211. Latsis did not object to the seaman status jury instructions in their entirety, but only contested that portion of the charge which explicitly took from the jury’s consideration the period of time that the Galileo was in dry-dock. The jury returned a verdict in favor of Chandris solely on the issue of Latsis’ status as a seaman under the Jones Act. Id., at 213.

Respondent appealed to the Court of Appeals for the Second Circuit, which vacated the judgment and remanded the case for a new trial. 20 F. 3d 45 (1994). The court emphasized that its longstanding test for seaman status under the Jones Act required “‘a more or less permanent connection with the ship,’” Salgado v. M. J. Rudolph Corp., 514 F. 2d 750, 755 (CA2 1975), a connection that need not be limited to time spent on the vessel but could also be established by the nature of the work performed. The court thought that the alternate formulation employed by the District Court (permanent assignment to the vessel or performance of a substantial part of his work on the vessel), which was derived from Offshore Co. v. Robison, 266 F. 2d 769, 779 (CA5 1959), improperly framed the issue for the jury primarily, if not solely, in terms of Latsis’ temporal relationship to the vessel. With that understanding of what the language of the Robi-son test implied, the court concluded that the District Court’s seaman status jury instructions constituted plain error under established Circuit precedent. The court then took this case as an opportunity to clarify its seaman status requirements, directing the District Court that the jury should be instructed on remand as follows:

“[T]he test of seaman status under the Jones Act is an employment-related connection to a vessel in navigation. The test will be met where a jury finds that (1) the plaintiff contributed to the function of, or helped accomplish the mission of, a vessel; (2) the plaintiff’s contribution was limited to a particular vessel or identifiable group of vessels; (3) the plaintiff’s contribution was substantial in terms of its (a) duration or (b) nature; and (4) the course of the plaintiff’s employment regularly exposed the plaintiff to the hazards of the sea.” 20 F. 3d, at 57.

Elsewhere on the same page, however, the court phrased the third prong as requiring a substantial connection in terms of both duration and nature. Finally, the Court of Appeals held that the District Court erred in instructing the jury that the time Latsis spent with the ship while it was in dry-dock could not count in the substantial connection equation. Id., at 55-56. Judge Kearse dissented, arguing that the dry-dock instruction was not erroneous and that the remainder of the charge did not constitute plain error. Id., at 58.

We granted certiorari, 513 U. S. 945 (1994), to resolve the continuing conflict among the Courts of Appeals regarding the appropriate requirements for seaman status under the Jones Act.

H-1 HH

The Jones Act provides a cause of action in negligence for “any seaman” injured “in the course of his employment.” 46 U. S. C. App. § 688(a). Under general maritime law prevailing prior to the statute’s enactment, seamen were entitled to “maintenance and cure” from their employer for injuries incurred “in the service of the ship” and to recover damages from the vessel’s owner for “injuries received by seamen in consequence of the unseaworthiness of the ship,” but they were “not allowed to recover an indemnity for the negligence of the master, or any member of the crew.” The Osceola, 189 U. S. 158, 175 (1903); see also Cortes v. Baltimore Insular Line, Inc., 287 U. S. 367, 370-371 (1932). Congress enacted the Jones Act in 1920 to remove the bar to suit for negligence articulated in The Osceola, thereby completing the trilogy of heightened legal protections (unavailable to other maritime workers) that seamen receive because of their exposure to the “perils of the sea.” See G. Gilmore & C. Black, Law of Admiralty §6-21, pp. 328-329 (2d ed. 1975); Robertson, A New Approach to Determining Seaman Status, 64 Texas L. Rev. 79 (1985) (hereinafter Robertson). Justice Story identified this animating purpose behind the legal regime governing maritime injuries when he observed that seamen “are emphatically the wards of the admiralty” because they “are by the peculiarity of their lives liable to sudden sickness from change of climate, exposure to perils, and exhausting labour.” Harden v. Gordon, 11 F. Cas. 480, 485, 483 (No. 6,047) (CC Me. 1823). Similarly, we stated in Wilander that “[traditional seamen’s remedies . . . have been ‘universally recognized as . . . growing out of the status of the seaman and his peculiar relationship to the vessel, and as a feature of the maritime law compensating or offsetting the special hazards and disadvantages to which they who go down to sea in ships are subjected.’” 498 U. S., at 354 (quoting Seas Shipping Co. v. Sieracki, 328 U. S. 85, 104 (1946) (Stone, C. J., dissenting)).

The Jones Act, however, does not define the term “seaman” and therefore leaves to the courts the determination of exactly which maritime workers are entitled to admiralty’s special protection. Early on, we concluded that Congress intended the term to have its established meaning under the general maritime law at the time the Jones Act was enacted. See Warner v. Goltra, 293 U. S. 155, 159 (1934). In Warner, we stated that “a seaman is a mariner of any degree, one who lives his life upon the sea.” Id., at 157. Similarly, in Norton v. Warner Co., 321 U. S. 565, 572 (1944), we suggested that “ ‘every one is entitled to the privilege of a seaman who, like seamen, at all times contributes to the labors about the operation and welfare of the ship when she is. upon a voyage’” (quoting The Buena Ventura, 243 F. 797, 799 (SDNY 1916)).

Congress provided some content for the Jones Act requirement in 1927 when it enacted the Longshore and Harbor Workers’ Compensation Act (LHWCA), which provides scheduled compensation (and the exclusive remedy) for injury to a broad range of land-based maritime workers but which also explicitly excludes from its coverage “a master or member of a crew of any vessel.” 44 Stat. (part 2) 1424, as amended, 33 U. S. C. § 902(3)(G). As the Court has stated on several occasions, the Jones Act and the LHWCA are mutually exclusive compensation regimes: “ ‘master or member of a crew’ is a refinement of the term ‘seaman’ in the Jones Act; it excludes from LHWCA coverage those properly-covered under the Jones Act.” Wilander, 498 U. S., at 347. Indeed, “it is odd but true that the key requirement for Jones Act coverage now appears in another statute.” Ibid. Injured workers who fall under neither category may still recover under an applicable state workers’ compensation scheme or, in admiralty, under general maritime tort principles (which are admittedly less generous than the Jones Act’s protections). See Cheavens, Terminal Workers’ Injury and Death Claims, 64 Tulane L. Rev. 361, 364-365 (1989).

Despite the LHWCA language, drawing the distinction between those maritime workers who should qualify as seamen and those who should not has proved to be a difficult task and the source of much litigation — particularly because “the myriad circumstances in which men go upon the water confront courts not with discrete classes of maritime employees, but rather with a spectrum ranging from the blue-water seaman to the land-based longshoreman.” Brown v. ITT Rayonier, Inc., 497 F. 2d 234, 236 (CA5 1974). The federal courts have struggled over the years to articulate generally applicable criteria to distinguish among the many varieties of maritime workers, often developing detailed multipronged tests for seaman status. Since the 1950’s, this Court largely has left definition of the Jones Act’s scope to the lower courts. Unfortunately, as a result, “[t]he perils of the sea, which mariners suffer and shipowners insure against, have met their match in the perils of judicial review.” Gilmore & Black, supra, §6-1, at 272. Or, as one court paraphrased Diderot in reference to this body of law: “ ‘We have made a labyrinth and got lost in it. We must find our way out.’” Johnson v. John F. Beasley Constr. Co., 742 F. 2d 1054, 1060 (CA7 1984), cert. denied, 469 U. S. 1211 (1985); see 9 Oeuvres Completes de Diderot, 203 (J. Assézat ed. 1875).

A

In Wilander, decided in 1991, the Court attempted for the first time in 33 years to clarify the definition of a “seaman” under the Jones Act. Jon Wilander was injured while assigned as a foreman supervising the sandblasting and painting of various fixtures and piping on oil drilling platforms in the Persian Gulf. His employer claimed that he could not qualify as a seaman because he did not aid in the navigation fimction of the vessels on which he served. Emphasizing that the question presented was narrow, we considered whether the term “seaman” is limited to only those maritime workers who aid in a vessel’s navigation.

After surveying the history of an “aid in navigation” requirement under both the Jones Act and general maritime law, we concluded that “all those with that ‘peculiar relationship to the vessel’ are covered under the Jones Act, regardless of the particular job they perform,” 498 U. S., at 354, and that “the better rule is to define ‘master or member of a crew’ under the LHWCA, and therefore ‘seaman’ under the Jones Act, solely in terms of the employee’s connection to a vessel in navigation,” ibid. Thus, we held that, although “[i]t is not necessary that a seaman aid in navigation or contribute to the transportation of the vessel,... a seaman must be doing the ship’s work.” Id., at 355. We explained that “[t]he key to seaman status is employment-related connection to a vessel in navigation,” and that, although “[w]e are not called upon here to define this connection in all details, ... we believe the requirement that an employee’s duties must ‘contribut[e] to the function of the vessel or to the accomplishment of its mission’ captures well an important requirement of seaman status.” Ibid.

Beyond dispensing with the “aid to navigation” requirement, however, Wilander did not consider the requisite connection to a vessel in any detail and therefore failed to end the prevailing confusion regarding seaman status.

B

Respondent urges us to find our way out of the Jones Act “labyrinth” by focusing on the seemingly activity-based policy underlying the statute (the protection of those who are exposed to the perils of the sea), and to conclude that anyone working on board a vessel for the duration of a “voyage” in furtherance of the vessel’s mission has the necessary employment-related connection to qualify as a seaman. Brief for Respondent 12-17. Such an approach, however, would run counter to our prior decisions and our understanding of the remedial scheme Congress has established for injured maritime workers. A brief survey of the Jones Act’s tortured history makes clear that we must reject the initial appeal of such a “voyage” test and undertake the more difficult task of developing a status-based standard that, although it determines Jones Act coverage without regard to the precise activity in which the worker is engaged at the time of the injury, nevertheless best furthers the Jones Act’s remedial goals.

Our Jones Act cases establish several basic principles regarding the definition of a seaman. First, “[wjhether under the Jones Act or general maritime law, seamen do not include land-based workers.” Wilander, supra, at 348; see also All-britton, Seaman Status in Wilander’s Wake, 68 Tulane L. Rev. 373, 387 (1994). Our early Jones Act decisions had not recognized this fundamental distinction. In International Stevedoring Co. v. Haverty, 272 U. S. 50 (1926), we held that a longshoreman injured while stowing cargo, and while aboard but not employed by a vessel at dock in navigable waters, was a seaman covered by the Jones Act. Recognizing that “for most purposes, as the word is commonly used, stevedores are not ‘seamen,’” the Court nevertheless concluded that “[w]e cannot believe that Congress willingly would have allowed the protection to men engaged upon the same maritime duties to vary with the accident of their being employed by a stevedore rather than by the ship.” Id., at . Because stevedores are engaged in “a maritime service formerly rendered by the ship’s crew,” ibid. (citing Atlantic Transport Co. of W. Va. v. Imbrovek, 234 U. S. 52, 62 (1914)), we concluded, they should receive the Jones Act’s protections. See also Uravic v. F. Jarka Co., 282 U. S. 234, 238 (1931); Jamison v. Encarnacion, 281 U. S. 635, 639 (1930). In 1946, the Court belatedly recognized that Congress had acted, in passing the LHWCA in 1927, to undercut the Court’s reasoning in the Haverty line of cases and to emphasize that land-based maritime workers should not be entitled to the seamen’s traditional remedies. Our decision in Swanson v. Marra Brothers, Inc., 328 U. S. 1, 7 (1946), acknowledged that Congress had expressed its intention to “confine the benefits of the Jones Act to the members of the crew of a vessel plying in navigable waters and to substitute for the right of recovery recognized by the Haverty case only such rights to compensation as are given by [the LHWCA].” See also South Chicago Coal & Dock Co. v. Bassett, 309 U. S. 251, 257 (1940). Through the LHWCA, therefore, Congress “explicitly den[ied] a right of recovery under the Jones Act to maritime workers not members of a crew who are injured on board a vessel.” Swanson, supra, at 6. And this recognition process culminated in Wilander with the Court’s statement that, “[w]ith the passage of the LHWCA, Congress established a clear distinction between land-based and sea-based maritime workers. The latter, who owe their allegiance to a vessel and not solely to a land-based employer, are seamen.” 498 U. S., at 347.

In addition to recognizing a fundamental distinction between land-based and sea-based maritime employees, our cases also emphasize that Jones Act coverage, like the jurisdiction of admiralty over causes of action for maintenance and cure for injuries received in the course of a seaman’s employment, depends “not on the place where the injury is inflicted . . . but on the nature of the seaman’s service, his status as a member of the vessel, and his relationship as such to the vessel and its operation in navigable waters.” Swanson, supra, at 4. Thus, maritime workers who obtain seaman status do not lose that protection automatically when on shore and may recover under the Jones Act whenever they are injured in the service of a vessel, regardless of whether the injury occurs on or off the ship. In O’Donnell v. Great Lakes Dredge & Dock Co., 318 U. S. 36 (1943), the Court held a shipowner liable for injuries caused to a seaman by a fellow crew member while the former was on shore repairing a conduit that was a part of the vessel and that was used for discharging the ship’s cargo. We explained: “The right of recovery in the Jones Act is given to the seaman as such, and, as in the case of maintenance and cure, the admiralty jurisdiction over the suit depends not on the place where the injury is inflicted but on the nature of the service and its relationship to the operation of the vessel plying in navigable waters.” Id., at 42-43. Similarly, the Court in Swanson emphasized that the LHWCA “leaves unaffected the rights of members of the crew of a vessel to recover under the Jones Act when injured while pursuing their maritime employment whether on board ... or on shore.” 328 U. S., at 7-8. See also Braen v. Pfeifer Oil Transp. Co., 361 U. S. 129, 131-132 (1959).

Our LHWCA cases also recognize the converse: Land-based maritime workers injured while on a vessel in navigation remain covered by the LHWCA, which expressly provides compensation for injuries to certain workers engaged in “maritime employment” that are incurred “upon the navigable waters of the United States,” 33 U. S. C. § 903(a). Thus, in Director, Office of Workers’ Compensation Programs v. Perini North River Associates, 459 U. S. 297 (1983), we held that a worker injured while “working on a barge in actual navigable waters” of the Hudson River, id., at 300, n. 4, could be compensated under the LHWCA, id., at 324. See also Parker v. Motor Boat Sales, Inc., 314 U. S. 244, 244-245 (1941) (upholding LHWCA coverage for a worker testing outboard motors who “was drowned when a motor boat in which he was riding capsized”). These decisions, which reflect our longstanding view of the LHWCA’s scope, indicate that a maritime worker does not become a “member of a crew” as soon as a vessel leaves the dock.

It is therefore well settled after decades of judicial interpretation that the Jones Act inquiry is fundamentally status based: Land-based maritime workers do not become seamen because they happen to be working on board a vessel when they are injured, and seamen do not lose Jones Act protection when the course of their service to a vessel takes them ashore. In spite of this background, respondent and Justice Stevens suggest that any maritime worker who is assigned to a vessel for the duration of a voyage — and whose duties contribute to the vessel’s mission — should be classified as a seaman for purposes of injuries incurred during that voyage. See Brief for Respondent 14; post, at 377 (opinion concurring in judgment). Under such a “voyage test,” which relies principally upon this Court’s statements that the Jones Act was designed to protect maritime workers who are exposed to the “special hazards” and “particular perils” characteristic of work on vessels at sea, see, e. g., Wilander, supra, at 354, the worker’s activities at the time of the injury would be controlling.

The difficulty with respondent’s argument, as the foregoing discussion makes clear, is that the LHWCA repudiated the Haverty line of cases and established that a worker is no longer considered to be a seaman simply because he is doing a seaman’s work at the time of the injury. Seaman status is not coextensive with seamen’s risks. See, e. g., Easley v. Southern Shipbuilding Corp., 965 F. 2d 1, 4-5 (CA5 1992), cert. denied, 506 U. S. 1050 (1993); Robertson 93 (following “the overwhelming weight of authority in taking it as given that seaman status cannot be established by any worker who fails to demonstrate that a significant portion of his work was done aboard a vessel” and acknowledging that “[sjome workers who unmistakably confront the perils of the sea, often in extreme form, are thereby left out of the seamen’s protections” (footnote omitted)). A “voyage test” would conflict with our prior understanding of the Jones Act as fundamentally status based, granting the negligence cause of action to those maritime workers who form the ship’s company. Swanson, supra, at 4-5; O’Donnell, supra, at 42-43.

Desper v. Starved Rock Ferry Co., 342 U. S. 187, 190 (1952), is not to the contrary. Although some language in that case does suggest that whether an individual is a seaman depends upon “the activity in which he was engaged at the time of injury,” the context of that discussion reveals that “activity” referred to the worker’s employment as a laborer on a vessel undergoing seasonal repairs while out of navigation, and not to his precise task at the time of injury. Similarly, despite Justice Harlan’s suggestion in dissent that the Court’s decision in Grimes v. Raymond Concrete Pile Co., 356 U. S. 252 (1958), necessarily construed the word seaman “to mean nothing more than a person injured while working at sea,” id., at 255, our short per curiam opinion in that case does not indicate that we adopted so expansive a reading of the statutory term. Citing our prior cases which emphasized that the question of seaman status is normally for the fact-finder to decide, see, e. g., Senko v. LaCrosse Dredging Corp., 352 U. S. 370, 371-372 (1957); Bassett, 309 U. S., at 257-258, we reversed the judgment of the Court of Appeals and held simply that the jury could have inferred from the facts presented that the petitioner was a member of a crew in light of his overall service to the company (as the District Court had concluded in ruling on a motion for a directed verdict at the close of petitioner’s case). Grimes, supra, at 253. That neither Desper nor Grimes altered our established course in favor of a voyage test is confirmed by reference to our later decision in Braen, supra, at 131, in which we repeated that “[t]he injured party must of course have ‘status as a member of the vessel’ for it is seamen, not others who may work on the vessel (Swanson v. Marra Bros., 328 U. S. 1, 4), to whom Congress extended the protection of the Jones Act.”

We believe it is important to avoid “ ‘engrafting upon the statutory classification of a “seaman” a judicial gloss so protean, elusive, or arbitrary as to permit a worker to walk into and out of coverage in the course of his regular duties.’” Barrett v. Chevron, U. S. A., Inc., 781 F. 2d 1067, 1075 (CA5 1986) (en banc) (quoting Longmire v. Sea Drilling Corp., 610 F. 2d 1342, 1347, n. 6 (CA5 1980)). In evaluating the employment-related connection of a maritime worker to a vessel in navigation, courts should not employ “a ‘snapshot’ test for seaman status, inspecting only the situation as it exists at the instant of injury; a more enduring relationship is contemplated in the jurisprudence.” Easley, supra, at 5. Thus, a worker may not oscillate back and forth between Jones Act coverage and other remedies depending on the activity in which the worker was engaged while injured. Reeves v. Mobile Dredging & Pumping Co., 26 F. 3d 1247, 1256 (CA3 1994). Unlike Justice Stevens, see post, at 383, we do not believe that any maritime worker on a ship at sea as part of his employment is automatically a member of the crew of the vessel within the meaning of the statutory terms. Our rejection of the voyage test is also consistent with the interests of employers and maritime workers alike in being able to predict who will be covered by the Jones Act (and, perhaps more importantly for purposes of the employers’ workers’ compensation obligations, who will be covered by the LHWCA) before a particular workday begins.

To say that our cases have recognized a distinction between land-based and sea-based maritime workers that precludes application of a voyage test for seaman status, however, is not to say that a maritime employee must work only on board a vessel to qualify as a seaman under the Jones Act. In Southwest Marine, Inc. v. Gizoni, 502 U. S. 81 (1991), decided only a few months after Wilander, we concluded that a worker’s status as a ship repairman, one of the enumerated occupations encompassed within the term “employee” under the LHWCA, 33 U. S. C. § 902(3), did not necessarily restrict the worker to a remedy under that statute. We explained that, “[w]hile in some cases a ship repairman may lack the requisite connection to a vessel in navigation to qualify for seaman status, . . . not all ship repairmen lack the requisite connection as a matter of law. This is so because ‘[i]t is not the employee’s particular job that is determinative, but the employee’s connection to a vessel.’” Gizoni, supra, at 89 (quoting Wilander, 498 U. S., at 354) (footnote omitted). Thus, we concluded, the Jones Act remedy may be available to maritime workers who are employed by a shipyard and who spend a portion of their time working on shore but spend the rest of their time at sea.

Beyond these basic themes, which are sufficient to foreclose respondent’s principal argument, our cases are largely silent as to the precise relationship a maritime worker must bear to a vessel in order to come within the Jones Act’s ambit. We have, until now, left to the lower federal courts the task of developing appropriate criteria to distinguish the “ship’s company” from those members of the maritime community whose employment is essentially land based.

C

The Court of Appeals for the First Circuit was apparently the first to develop a generally applicable test for seaman status. In Carumbo v. Cape Cod S. S. Co., 123 F. 2d 991 (1941), the court retained the pre-Swanson view that “the word ‘seaman’ under the Jones Act [did] not mean the same thing as ‘member of a crew’ under the [LHWCA],” 123 F. 2d, at 994. It concluded that “one who does any sort of work aboard a ship in navigation is a ‘seaman’ within the meaning of the Jones Act.” Id., at 995. To the phrase “member of a crew,” on the other hand, the court gave a more restrictive meaning. The court adopted three elements to define the phrase that had been used at various times in prior cases, holding that “[t]he requirements that the ship be in navigation; that there be a more or less permanent connection with the ship; and that the worker be aboard primarily to aid in navigation appear to us to be the essential and decisivé elements of the definition of a ‘member of a crew.’ ” Ibid. Cf. Senko, supra, at 375 (Harlan, J., dissenting) (“According to past decisions, to be a ‘member of a crew’ an individual must have some connection, more , or less permanent, with a ship and a ship’s company”). Once it became clear that the phrase “master or member of a crew” from the LHWCA is coextensive with the term “seaman” in the Jones Act, courts accepted the Carumbo formulation of master or member of a crew in the Jones Act context. See Boyd v. Ford Motor Co., 948 F. 2d 283 (CA6 1991); Estate of Wenzel v. Seaward Marine Services, Inc., 709 F. 2d 1326, 1327 (CA9 1983); Whittington v. Sewer Constr. Co., 541 F. 2d 427, 436 (CA4 1976); Griffith v. Wheeling Pittsburgh Steel Corp., 521 F. 2d 31, 36 (CA3 1975), cert. denied, 423 U. S. 1054 (1976); McKie v. Diamond Marine Co., 204 F. 2d 132, 136 (CA5 1953). The Court of Appeals for the Second Circuit initially was among the jurisdictions to adopt the Carumbo formulation as the basis of its seaman status inquiry, see Salgado v. M. J. Rudolph Corp., 514 F. 2d, at 755, but that court took the instant case as an opportunity to modify the traditional test somewhat (replacing the “more or less permanent connection” prong with a requirement that the connection be “substantial in terms of its (a) duration and (b) nature”), 20 F. 3d, at 57.

The second major body of seaman status law developed in the Court of Appeals for the Fifth Circuit, which has a substantial Jones Act caseload, in the wake of Offshore Co. v. Robison, 266 F. 2d 769 (CA5 1959). At the time of his injury, Robison was an oil worker permanently assigned to a drilling rig mounted on a barge in the Gulf of Mexico. In sustaining the jury’s award of damages to Robison under the Jones Act, the court abandoned the aid in navigation requirement of the traditional test and held as follows:

“[T]here is an evidentiary basis for a Jones Act case to go to the jury: (1) if there is evidence that the injured workman was assigned permanently to a vessel ... or performed a substantial part of his work on the vessel; and (2) if the capacity in which he was employed or the duties which he performed contributed to the function of the vessel or to the accomplishment of its mission, or to the operation or welfare of the vessel in terms of its maintenance during its movement or during anchorage for its future trips.” Id., at 779 (footnote omitted).

Soon after Robison, the Fifth Circuit modified the test to allow seaman status for those workers who had the requisite connection with an “identifiable fleet” of vessels, a finite group of vessels under common ownership or control. Braniff v. Jackson Avenue-Gretna Ferry, Inc., 280 F. 2d 523, 528 (1960). See also Barrett, 781 F. 2d, at 1074; Bertrand v. International Mooring & Marine, Inc., 700 F. 2d 240 (CA5 1983), cert. denied, 464 U. S. 1069 (1984). The modified Rob-ison formulation, which replaced the Carumbo version as the definitive test for seaman status in the Fifth Circuit, has been highly influential in other courts as well. See Robertson 95; Miller v. Patton-Tully Transp. Co., 851 F. 2d 202, 204 (CA8 1988); Caruso v. Sterling Yacht & Shipbuilders, Inc., 828 F. 2d 14, 15 (CA11 1987); Bennett v. Perini Corp., 510 F. 2d 114, 115 (CA1 1975).

While the Carumbo and Robison approaches may not seem all that different at first glance, subsequent developments in the Fifth Circuit’s Jones Act jurisprudence added a strictly temporal gloss to the Jones Act inquiry. Under Barrett v. Chevron, U. S. A., Inc., supra, if an employee’s regular duties require him to divide his time between vessel and land, his status as a crew member is determined “in the context of his entire employment” with his current employer. Id., at 1075. See also Allbritton, 68 Tulane L. Rev., at 386; Longmire, 610 F. 2d, at 1347 (explaining that a worker’s seaman status “should be addressed with reference to the nature and location of his occupation taken as a whole”). In Barrett, the court noted that the worker “performed seventy to eighty percent of his work on platforms and no more than twenty to thirty percent of his work on vessels” and then concluded that, “[bjecause he did not perform a substantial portion of his work aboard a vessel or fleet of vessels, he failed to establish that he was a member of the crew of a vessel.” 781 F. 2d, at 1076. Since Barrett, the Fifth Circuit consistently has analyzed the problem in terms of the percentage of work performed on vessels for the employer in question — and has declined to find seaman status where the employee spent less than 30 percent of his time aboard ship. See, e. g., Palmer v. Fayard Moving & Transp. Corp., 930 F. 2d 437, 439 (1991); Lormand v. Superior Oil Co., 845 F. 2d 536, 541 (1987), cert. denied, 484 U. S. 1031 (1988); cf. Leonard v. Dixie Well Service & Supply, Inc., 828 F. 2d 291, 295 (1987); Pickle v. International Oilfield Divers, Inc., 791 F. 2d 1237, 1240 (1986), cert. denied, 479 U. S. 1059 (1987).

Although some Courts of Appeals have varied the applicable tests to some degree, see, e.g., Johnson v. John F. Beasley Constr. Co., 742 F. 2d, at 1062-1063, the traditional Carumbo seaman status formulation and the subsequent Robison modification are universally recognized, and one or the other is applied in every Federal Circuit to have considered the issue. See Bull, Seaman Status Revisited: A Practical Guide To Status Determination, 6 U. S. F. Mar. L. J. 547, 562-572 (1994) (collecting cases). The federal courts generally require at least a significant connection to a vessel in navigation (or to an identifiable fleet of vessels) for a maritime worker to qualify as a seaman under the Jones Act. Although the traditional test requires a “more or less permanent connection” and the Robison formulation calls for “substantial” work aboard a vessel, “this general requirement varies little, if at all, from one jurisdiction to another,” Bull, supra, at 587, and “[tjhe courts have repeatedly held that the relationship creating seaman status must be substantial in point of time and work, and not merely sporadic,” id., at 587-588.

D

From this background emerge the essential contours of the “employment-related connection to a vessel in navigation,” Wilander, 498 U. S., at 355, required for an employee to qualify as a seaman under the Jones Act. We have said that, in giving effect to the term “seaman,” our concern must be “to define the meaning for the purpose of a particular statute” and that its use in the Jones Act “must be read in the light of the mischief to be corrected and the end to be attained.” Warner, 293 U. S., at 158. Giving effect to those guiding principles, we think that the essential requirements for seaman status are twofold. First, as we emphasized in Wi-lander, “an employee’s duties must ‘contribute] to the function of the vessel or to the accomplishment of its mission.’” 498 U. S., at 355 (quoting Robison, 266 F. 2d, at 779). The Jones Act’s protections, like the other admiralty protections for seamen, only extend to those maritime employees who do the ship’s work. But this threshold requirement is very broad: “All who work at sea in the service of a ship” are eligible for seaman status. 498 U. S., at 354.

Second, and most important for our purposes here, a seaman must have a connection to a vessel in navigation (or to an identifiable group of such vessels) that is substantial in terms of both its duration and its nature. The fundamental purpose of this substantial connection requirement is to give full effect to the remedial scheme created by Congress and to separate the sea-based maritime employees who are entitled to Jones Act protection from those land-based workers who have only a transitory or sporadic connection to a vessel in navigation, and therefore whose employment does not regularly expose them to the perils of the sea. See IB A. Jenner, Benedict on Admiralty § 11a, pp. 2-10.1 to 2-11 (7th ed. 1994) (“If it can be shown that the employee performed a significant part of his work on board the vessel on which he was injured, with at least some degree of regularity and continuity, the test for seaman status will be satisfied” (footnote omitted)). This requirement therefore determines which maritime employees in Wilander’s broad category of persons eligible for seaman status because they are “doing the ship’s work,” 498 U. S., at 355, are in fact entitled to the benefits conferred upon seamen by the Jones Act because they have the requisite employment-related connection to a vessel in navigation.

It is important to recall that the question of who is a “member of a crew,” and therefore who is a “seaman,” is a mixed question of law and fact. Because statutory terms are at issue, their interpretation is a question of law and it is the court’s duty to define the appropriate standard. Wilander, 498 U. S., at 356. On the other hand, “[i]f reasonable persons, applying the proper legal standard, could differ as to whether the employee was a ‘member of a crew,’ it is a question for the jury.” Ibid. See also Senko, 352 U. S., at 374 (explaining that “the determination of whether an injured person was a ‘member of a crew’ is to be left to the finder of fact” and that “a jury’s decision is final if it has a reasonable basis”). The jury should be permitted, when determining whether a maritime employee has the requisite employment-related connection to a vessel in navigation to qualify as a member of the vessel’s crew, to consider all relevant circumstances bearing on the two elements outlined above.

In defining the prerequisites for Jones Act coverage, we think it preferable to focus upon the essence of what it means to be a seaman and to eschew the temptation to create detailed tests to effectuate the congressional purpose, tests that tend to become ends in and of themselves. The principal formulations employed by the Courts of Appeals — “more or less permanent assignment” or “connection to a vessel that is substantial in terms of its duration and nature” — are simply different ways of getting at the same basic point: The Jones Act remedy is reserved for sea-based maritime employees whose work regularly exposes them to “the special hazards and disadvantages to which they who go down to sea in ships are subjected.” Sieracki, 328 U. S., at 104 (Stone, C. J., dissenting). Indeed, it is difficult to discern major substantive differences in the language of the two phrases. In our view, “the total circumstances of an individual’s employment must be weighed to determine whether he had a sufficient relation to the navigation of vessels and the perils attendant thereon.” Wallace v. Oceaneering Int’l, 727 F. 2d 427, 432 (CA5 1984). The duration of a worker’s connection to a vessel and the nature of the worker’s activities, taken together, determine whether a maritime employee is a seaman because the ultimate inquiry is whether the worker in question is a member of the vessel’s crew or simply a land-based employee who happens to be working on the vessel at a given time.

Although we adopt the centerpiece of the formulation used by the Court of Appeals in this case — that a seaman must have a connection with a vessel in navigation that is substantial in both duration and nature — we should point out how our understanding of the import of that language may be different in some respects from that of the court below. The Court of Appeals suggested that its test for seaman status “does not unequivocally require a Jones Act seaman to be substantially connected to a vessel” in terms of time if the worker performs important work on board on a steady, although not necessarily on a temporally significant, basis. 20 F. 3d, at 53. Perhaps giving effect to this intuition, or perhaps reacting to the temporal gloss placed on the Robison language by later Fifth Circuit decisions, the court phrased its standard at one point as requiring a jury to find that a Jones Act plaintiff’s contribution to the function of the vessel was substantial in terms of its duration or nature. 20 F. 3d, at 57. It is not clear which version (“duration or nature” as opposed to “duration and nature”) the Court of Appeals intended to adopt for the substantial connection requirement — or indeed whether the court saw a significant difference between the two. Nevertheless, we think it is important that a seaman’s connection to a vessel in fact be substantial in both respects.

We agree with the Court of Appeals that seaman status is not merely a temporal concept, but we also believe that it necessarily includes a temporal element. A maritime worker who spends only a small fraction of his working time on board a vessel is fundamentally land based and therefore not a member of the vessel’s crew, regardless of what his duties are. Naturally, substantiality in this context is determined by reference to the period covered by the Jones Act plaintiff’s maritime employment, rather than by some absolute measure. Generally, the Fifth Circuit seems to have identified an appropriate rule of thumb for the ordinary case: A worker who spends less than about 30 percent of his time in the service of a vessel in navigation should not qualify as a seaman under the Jones Act. This figure of course serves as no more than a guideline established by years of experience, and departure from it will certainly be justified in appropriate cases. As we have said, “[t]he inquiry into seaman status is of necessity fact specific; it will depend on the nature of the vessel and the employee’s precise relation to it.” Wilander, 498 U. S., at 356. Nevertheless, we believe that courts, employers, and maritime workers can all benefit from reference to these general principles. And where undisputed facts reveal that a maritime worker has a clearly inadequate temporal connection to vessels in navigation, the court may take the question from the jury by granting summary judgment or a directed verdict. See, e. g., Palmer, 930 F. 2d, at 439.

On the other hand, we see no reason to limit the seaman status inquiry, as petitioners contend, exclusively to an examination of the overall course of a worker’s service with a particular employer. Brief for Petitioners 14-15. When a maritime worker’s basic assignment changes, his seaman status may change as well. See Barrett, 781 F. 2d, at 1077 (Rubin, J., dissenting) (“An assignment to work as a crew member, like the voyage of a vessel, may be brief, and the Robison test is applicable in deciding the worker’s status during any such employment”); Longmire, 610 F. 2d, at 1347, n. 6. For example, we can imagine situations in which someone who had worked for years in an employer’s shoreside headquarters is then reassigned to a ship in a classic seaman’s job that involves a regular and continuous, rather than intermittent, commitment of the worker’s labor to the function of a vessel. Such a person should not be denied seaman status if injured shortly after the reassignment, just as someone actually transferred to a desk job in the company’s office and injured in the hallway should not be entitled to claim seaman status on the basis of prior service at sea. If a maritime employee receives a new work assignment in which his essential duties are changed, he is entitled to have the assessment of the substantiality of his vessel-related work made on the basis of his activities in his new position. See Cheavens, 64 Tulane L. Rev., at 389-390. Thus, nothing in our opinion forecloses Jones Act coverage, in appropriate cases, for Justice Stevens’ paradigmatic maritime worker injured while reassigned to “a lengthy voyage on the high seas,” -post, at 386. While our approach maintains the status-based inquiry this Court’s earlier cases contemplate, we recognize that seaman status also should not be some immutable characteristic that maritime workers who spend only a portion of their time at sea can never attain.

One final issue remains for our determination: whether the District Court erred in instructing the jurors that, “[i]n determining whether Mr. Latsis performed a substantial part of his work on the vessel, [they could] not consider the period of time the Galileo was in drydock in Germany, because during that time period she was out of navigation.” We agree with the Court of Appeals that it did.

The foregoing discussion establishes that, to qualify as a seaman under the Jones Act, a maritime employee must have a substantial employment-related connection to a vessel in navigation. See Wilander, supra, at 354-355. Of course, any time Latsis spent with the Galileo while the ship was out of navigation could not count as time spent at sea for purposes of that inquiry, and it would have been appropriate for the District Court to make this clear to the jury. Yet the underlying inquiry whether a vessel is or is not “in navigation” for Jones Act purposes is a fact-intensive question that is normally for the jury and not the court to decide. See Butler v. Whiteman, 356 U. S. 271 (1958) (per curiam); 2 M. Norris, Law of Seamen §30.13, p. 363 (4th ed. 1985) (“Whether the vessel is in navigation presents a question of fact to be determined by the trier of the facts. When the case is tried to a jury the fact question should be left to their consideration if sufficient evidence has been presented to provide the basis for jury consideration”). Removing the issue from the jury’s consideration is only appropriate where the facts and the law will reasonably support only one conclusion, Anderson v. Liberty Lobby, Inc., 477 U. S. 242, 250-251 (1986), and the colloquy between the court and counsel does not indicate that the District Court made any such findings before overruling respondent’s objection to the drydock instruction. See Tr. 432. Based upon the record before us, we think the court failed adequately to justify its decision to remove the question whether the Galileo was “in navigation” while in Bremerhaven from the jury.

Under our precedent and the law prevailing in the Circuits, it is generally accepted that “a vessel does not cease to be a vessel when she is not voyaging, but is at anchor, berthed, or at dockside,” DiGiovanni v. Traylor Bros., Inc., 959 F. 2d 1119, 1121 (CAI) (en banc), cert. denied, 506 U. S. (1992), even when the vessel is undergoing repairs. See Butler, supra, at 271; Senko, 352 U. S., at 373; Norris, supra, at 364 (“[A] vessel is in navigation . . . when it returns from a voyage and is taken to a drydock or shipyard to undergo repairs in preparation to making another trip, and likewise a vessel is in navigation, although moored to a dock, if it remains in readiness for another voyage” (footnotes omitted)). At some point, however, repairs become sufficiently significant that the vessel can no longer be considered in navigation. In West v. United States, 361 U. S. 118 (1959), we held that a shoreside worker was not entitled to recover for unseaworthiness because the vessel on which he was injured was undergoing an overhaul for the purpose of making her seaworthy and therefore had been withdrawn from navigation. We explained that, in such cases, “the focus should be upon the status of the ship, the pattern of the repairs, and the extensive nature of the work contracted to be done.” Id., at 122. See also United N. Y. and N. J. Sandy Hook Pilots Assn. v. Halecki, 358 U. S. 613 (1959); Desper, 342 U. S., at 191. The general rule among the Courts of Appeals is that vessels undergoing repairs or spending a relatively short period of time in drydock are still considered to be “in navigation” whereas ships being transformed through “major” overhauls or renovations are not. See Bull, 6 U. S. F. Mar. L. J., at 582-584 (collecting eases).

Obviously, while the distinction at issue here is one of degree, the prevailing view is that “major renovations can take a ship out of navigation, even though its use before and after. the work will be the same.” McKinley v. All Alaskan Seafoods, Inc., 980 F. 2d 567, 570 (CA9 1992). Our review of the record in this case uncovered relatively little evidence bearing on the Galileo’s status during the repairs, and even less discussion of the question by the District Court. On the one hand, the work on the Chandris vessel took only about six months, which seems to be a relatively short period of time for important repairs on oceangoing vessels. Cf. id., at 571 (17-month-long project involving major structural changes took the vessel out of navigation); Wixom v. Boland Marine & Manufacturing Co., 614 F. 2d 956 (CA5 1980) (similar 3-year project); see also Senko, supra, at 373 (noting that “[e]ven a transoceanic liner may be confined to berth for lengthy periods, and while there the ship is kept in repair by its 'crew’ ” — and that “[t]here can be no doubt that a member of its crew would be covered by the Jones Act during this period, even though the ship was never in transit during his employment”). On the other hand, Latsis’ own description of the work performed suggests that the modifications to the vessel were actually quite significant, including the removal of the ship’s bottom plates and propellers, the addition of bow thrusters, overhaul of the main engines, reconstruction of the boilers, and renovations of the cabins and other passenger areas of the ship. See App. 93-94. On these facts, which are similar to those in McKinley, it is possible that Chandris could be entitled to partial summary judgment or a directed verdict concerning whether the Galileo remained in navigation while in drydock; the record, however, contains no stipulations or findings by the District Court to justify its conclusion that the modifications to the Galileo were sufficiently extensive to remove the vessel from navigation as a matter of law. On that basis, we agree with the Court of Appeals that the District Court’s drydock instruction was erroneous.

Even if the District Court had been justified in directing a verdict on the question whether the Galileo remained in navigation while in Bremerhaven, we think that the court’s charge to the jury swept too broadly. Instead of simply noting the appropriate legal conclusion and instructing the jury not to consider the time Latsis spent with the vessel in dry-dock as time spent with a vessel in navigation, the District Court appears to have prohibited the jury from considering Latsis’ stay in Bremerhaven for any purpose. In our view, Latsis’ activities while the vessel was in drydock are at least marginally relevant to the underlying inquiry (whether Lat-sis was a seaman and not a land-based maritime employee). Naturally, the jury would be free to draw several inferences from Latsis’ work during the conversion, not all of which would be in his favor. But the choice among such permissible inferences should have been left to the jury, and we think the District Court’s broadly worded instruction improperly deprived the jury of that opportunity by forbidding the consideration of Latsis’ time in Bremerhaven at all.

>

Under the Jones Act, “[i]f reasonable persons, applying the proper legal standard, could differ as to whether the employee was a ‘member of a crew,’ it is a question for the jury.” Wilander, 498 U. S., at 356. On the facts of this case, given that essential points are in dispute, reasonable factfinders could disagree as to whether Latsis was a seaman. Because the question whether the Galileo remained “in navigation” while in drydock should have been submitted to the jury, and because the decision on that issue might affect the outcome of the ultimate seaman status inquiry, we affirm the judgment of the Court of Appeals remanding the case to the District Court for a new trial.

On remand, the District Court should charge the jury in a manner consistent with our holding that the “employment-related connection to a vessel in navigation” necessary to qualify as a seaman under the Jones Act, id., at 355, comprises two basic elements: The worker’s duties must contribute to the function of the vessel or to the accomplishment of its mission, and the worker must have a connection to a vessel in navigation (or an identifiable group of vessels) that is substantial in terms of both its duration and its nature. As to the latter point, the court should emphasize that the Jones Act was intended to protect sea-based maritime workers, who owe their allegiance to a vessel, and not land-based employees, who do not. By instructing juries in Jones Act cases accordingly, courts can give proper effect to the remedial scheme Congress has created for injured maritime workers.

It is so ordered.

We granted certiorari on the following question, set forth in the petition: “What employment-related connection to a vessel in navigation is necessary for a maritime worker to qualify as a seaman under the Jones Act, 46 U. S. C. § 688?” Pet. for Cert. i. Petitioners argue for the first time in their opening brief on the merits that, because respondent failed to raise a timely objection under Rule 51 of the Federal Rules of Civil Procedure, we should limit the scope of our review to the narrower issue of whether the District Court’s seaman status jury instructions constituted “plain error.” Brief for Petitioners 12-14. Under this Court’s Rule 14.1(a), “[o]nly the questions set forth in the petition [for certiorari], or fairly included therein, will be considered by the Court,” see, e. g., Berkemer v. McCarty, 468 U. S. 420, 443, n. 38 (1984), and our Rule 24.1(a) provides that a merits brief should not “raise additional questions or change the substance of the questions already presented” in the petition. See also Izumi Seimitsu Kogyo Kabushiki Kaisha v. U. S. Philips Corp., 610 U. S. 27, 31-32 (1993); Taylor v. Freeland & Kronz, 503 U. S. 638, 646-646 (1992). Because petitioners did not raise the issue in the petition for certiorari, we will not consider any argument they may have under Rule 51 concerning the effect of respondent’s failure to object to the seaman status jury instructions in their entirety.
