The government appeals the August 19, 1997, order of the District Court for the District of the Virgin Islands suppressing evidence seized during a warrantless search of the MW Venture Pride. We conclude that the search of the Venture Pride at issue in this appeal was authorized by 14 U.S.C. § 89(a) (1994) since the Venture Pride was situated in U.S. territorial waters while undergoing repair. Section 89(a) permits war-rantless searches of vessels in U.S. territorial waters based solely upon a reasonable suspicion of criminal activity, and the government possessed the requisite reasonable suspicion that a search would produce further evidence that Venture Pride had violated U.S. environmental laws. We will reverse the order of the district court and remand for further proceedings.
I.
On March 26, 1995, the U.S. Coast Guard Marine Safety Detachment Office in St. Thomas received a telephone call reporting an oil spill in Red Hook harbor, to which the Coast Guard dispatched Lt. Keith Janssen. Janssen interviewed an employee of the marina, who pointed out a sheen where the oil spill had occurred, and Janssen took a sample of the sheen.
Janssen subsequently spoke with a witness to the spill, who identified the Venture Pride as the offending vessel. The Venture Pride is owned by Varlack Ventures, Inc., and operates as a commercial ferry under a Coast Guard certificate of inspection. When the Venture Pride returned to Red Hook harbor, Janssen located the specific opening on the vessel through which the oil had flowed because a witness identified the location on a diagram of the vessel that Janssen sketched.
Janssen then boarded the Venture Pride without a warrant and asked for the captain, who was not on board. He instructed the crew to arrange for the captain’s return. Janssen received permission from a member of the crew to inspect the engine room, where he noted oil in the bilge. He also observed a hose leading from the bilge to an overboard fitting as well as an illegally-wired bilge pump. Janssen took a sample of the oil in the bilge and, after disembarking, of the oil from the overboard discharge fitting.
Janssen then boarded the Venture Pride a second time and gave a .federal letter of interest to the captain, Hubert Fredericks, who had since come on board. ,Fredericks gave Janssen a statement about the spill and acknowledged that he had not reported the spill in Red Hook harbor nor a possible spill in Cruz Bay, St. John. Janssen thereupon revoked the Venture Pride’s certificate of inspection.
On March 27, 1995, Janssen spoke with Antonio Thomas, who supervised maintenance for Varlack Ventures. Thomas informed him that the Venture Pride was in the north branch of Cruz Bay. Janssen instructed Thomas not to repair the Venture Pride since Coast Guard officers planned to photograph her the following day. On *215 March 28, 1995, Janssen and another Coast Guard officer boarded the Venture Pride without a warrant. They videotaped and photographed the interior and exterior of the ship. Janssen noticed that a large amount of oil had been removed from the bilge.
Fredericks and Varlaek Ventures were in-dieted for knowingly discharging oil into U.S. waters in violation of 33 U.S.C. §§ 1319(c)(2)(A), 1321(b)(3) (1994), faffing to report an oil spill in violation of 33 U.S.C. § 1321(b)(5) (1994), and aiding and abetting such activities in violation of 18 U.S.C. § 2 (1994). Varlaek Ventures also was indicted for violating 33 U.S.C. § 1319(e)(1) by negligently discharging oil into U.S. waters. Fredericks subsequently filed a motion to suppress his and the crew’s statements to Janssen as well as evidence obtained during the two warrantless searches, March 26 and 28, 1995. Following an evidentiary hearing, the district court ruled that Fredericks’s and the crew’s statements, as well as the evidence obtained during the search on March 26, were admissible. The district court suppressed evidence obtained during the March 28 search. The government appeals from that portion of the district court order which suppresses evidence from the search on March 28. Varlaek Ventures did not join the suppression motion in the district court and does not take any position in this appeal.
II.
Our jurisdiction over this appeal arises under 18 U.S.C. § 3731 (1994). We will exercise plenary review of the district court’s legal determinations and applications of law to facts. We will review the district court’s factual findings for clear error.
See Universal Minerals, Inc. v. C.A. Hughes & Co.,
III.
Usually, our point of departure for a Fourth Amendment inquiry would be whether Fredericks has a reasonable expectation of privacy in the areas of his vessel searched by the Coast Guard; however, we have no need to decide this issue in the instant case. Even assuming Fredericks has standing, the Coast Guard officers had the requisite level of suspicion required for searching vessels in U.S. territorial waters, and no warrant was needed for the search.
A.
Determining whether a plaintiff has standing to challenge a search equates to determining whether the plaintiff has a reasonable expectation of privacy in the property searched.
See Rakas v. Illinois,
Third Circuit precedent is inconclusive regarding whether the captain of a ship can have a reasonable expectation of privacy in the public areas of his vessel such as the engine room,
3
and an analysis of explicit positions taken by our sister courts of appeals on this issue fails to reveal any consistent doctrine. In
United States v. Lopez,
However, as our analysis infra explicates, we have no need to decide whether Freder-icks enjoyed a reasonable expectation of privacy in the public areas of his vessel since, even if he did, the Coast Guard officers fulfilled the requirements for conducting a war-rantless search of his vessel.
B.
Before examining the justification for the Coast Guard’s search, we must first ascertain the Venture Pride’s location since the standard might differ depending upon whether the ship was on land or in the water. The district court found that the Venture Pride was in drydock at the time of the March 28 search. However, the government claims that the ship was actually in the water, and the government cites Janssen’s testimony that the ship “was in the north branch of Cruz bay, also referred to as the Creek.” App. at 77. Fredericks does not point to any countervailing testimony that supports the district court’s conclusion that the Venture Pride was in drydock. The testimony before the district court was uncontested that, although the vessel may have been undergoing repairs, it was not in drydock but in the water. The district court’s factual finding was clearly erroneous since “we are left with a definite and firm conviction that a mistake has been committed.”
United States v. Roy,

We have previously joined our sister courts of appeals in interpreting section 89(a)
*217
to allow searches of vessels for criminal activities based upon reasonable suspicion of criminal activity.
See Wright-Barker,
The Coast Guard undoubtedly possessed reasonable suspicion of criminal activity in this case. We have not previously defined reasonable suspicion for the purposes of section 89(a), but the Eleventh Circuit defines reasonable suspicion in the section 89(a) context as follows:
Although we examine the totality of the circumstances to determine reasonable suspicion, reasonable suspicion must be more than a mere generalized suspicion or hunch. United States v. Pearson,791 F.2d 867 , 870 (11th Cir.1986), cert. denied,479 U.S. 991 ,107 S.Ct. 590 ,93 L.Ed.2d 591 (1986); United States v. Reeh,780 F.2d 1541 , 1544 (11th Cir.1986). Reasonable suspicion must be based on specific articulable facts, together with rational inferences drawn from those facts, which reasonably warrant suspicion of criminal activity. United States v. Brignoni-Ponce,422 U.S. 873 , 884,95 S.Ct. 2574 , 2581,45 L.Ed.2d 607 (1975). Law enforcement officers may subjectively assess those facts in light of their expertise.
Roy,
Concerning the applicability of the Fourth Amendment’s warrant requirement, section 89(a) contains no provision requiring a warrant, nor have any courts of appeals required a warrant for searches based upon a reasonable suspicion of criminal activity that are conducted pursuant to section 89(a).
See, e.g., Williams,
*218 IV.
For the above reasons, we will reverse the August 19, 1997, order of the district court suppressing evidence seized during the March 28, 1995, warrantless search of the Venture Pride. We will remand the case for further proceedings.
Notes
. The Fourth Amendment also requires that the individual manifest a subjective expectation of privacy in the property searched.
See California v. Greenwood,
. On this appeal, we will assume that Fredericks could still assert the prerogatives and authority as captain of the Venture Pride even though he was not on board the vessel during the search on March 28.
.In
United States v. Demanett,
. Section 89(a) reads as follows:
(a) The Coast Guard may make inquiries, examinations, inspections, searches, seizures, and arrests upon the high seas and waters over which the United States has jurisdiction, for the prevention, detection, and suppression of violations of laws of the United States. For such purposes, commissioned, warrant, and petty officers may at any time go on board of any vessel subject to the jurisdiction, or to the operation of any law, of the United States, address .inquiries to those on board, examine the ship's documents and papers, and examine, inspect, and search the vessel and use all necessary force to compel compliance. When from such inquiries, examination, inspection, or search it appears that a breach of the laws of the United States rendering a person liable to arrest is being, or has been committed, by any person, such person shall be arrested or, if escaping to shore, shall be immediately pursued and arrested on shore, or other lawful and appropriate action shall be taken; or, if it shall appear that a breach of the laws of the United States has been committed so as to render such vessel, or the merchandise, or any part thereof, on board of, or brought into the United States by, such vessel, liable to forfeiture, or so as to render such vessel liable to a fine or penally and if necessary to secure such fine or penalty, such vessel or such merchandise, or both, shall be seized.
14 U.S.C. § 89(a).
. The Fourth Circuit has expressed in dicta its agreement with the conclusion articulated in
Lopez. See United States v. Manbeck,
. We note that, given that a boat’s mobility creates exigent circumstances, the March 28 search would have been justified even if section 89(a) was inapplicable since the Coast Guard possessed probable cause to search the Venture Pride. Searches not authorized under section 89(a) fall under regular Fourth Amendment jurisprudence, in which probable cause is required. We have previously defined probable cause "in terms of facts and circumstances sufficient to warrant a prudent man in believing that the [suspect] had committed or was committing an offense.”
