    OPINION
    TALLMAN, Circuit Judge:
    We confront the constitutional limits of our extraterritorial
    jurisdiction in yet another major drug-smuggling operation on
    the waters of the eastern Pacific Ocean. Anatoli Zakharov
    appeals his jury conviction for (1) conspiracy to possess over
    9200 kilograms of cocaine with intent to distribute on board
    a vessel, and (2) possession of the cocaine with intent to dis-
    tribute on board the vessel. He challenges the amended Mari-
    time Drug Law Enforcement Act (“MDLEA”), codified at 46
    U.S.C. app. §§ 1901-1904, as unconstitutional on the grounds
    that Congress removed jurisdiction from the enumerated ele-
    ments of the maritime drug-smuggling offense that must be
    decided by a jury beyond a reasonable doubt. He also chal-
    lenges the district court’s failure to suppress evidence of his
    confession and the sufficiency of evidence supporting his con-
    victions.
    We have jurisdiction pursuant to 28 U.S.C. § 1291 and
    affirm Zakharov’s convictions. First, the MDLEA is constitu-
    tional as applied to Zakharov. Facts underlying statutory juris-
    diction were not contested, and determination of
    constitutional nexus jurisdiction is properly within the prov-
    ince of the court, not the jury. Second, we find the evidence
    sufficient to establish the required nexus between the United
    18602              UNITED STATES v. ZAKHAROV
    States and the defendant’s drug-smuggling activities. Third,
    the district court properly determined that Zakharov’s confes-
    sion should not be suppressed because the Fourth Amendment
    does not apply to non-resident aliens outside of the United
    States. Fourth, the eleven-day delay in bringing Zakharov
    before a magistrate judge was not unreasonable under Federal
    Rule of Criminal Procedure 5(a) in light of the time necessary
    to transport him by sea to the United States. Finally, evidence
    of Zakharov’s confession was properly admitted, and suffi-
    cient evidence existed to allow any rational trier of fact to find
    him guilty beyond a reasonable doubt. We uphold the convic-
    tions.
    But, because we cannot reliably determine from the record
    “whether the sentence imposed would have been materially
    different had the district court known that the [federal] sen-
    tencing guidelines were advisory,” United States v. Ameline,
    
    409 F.3d 1073
    , 1074 (9th Cir. 2005) (en banc), we grant a
    limited remand as to the sentence imposed.
    I
    Zakharov was a crew member aboard the Svesda Maru, a
    fishing vessel registered in the country of Belize. On April 28,
    2001, the vessel was 500 miles off the coast of southern Mex-
    ico in international waters when it was spotted by the crew of
    the USS Rodney M. Davis, a United States Navy frigate per-
    forming drug interdiction and maritime patrol duties in coop-
    eration with the United States Coast Guard. A seven-member
    Coast Guard Law Enforcement Detachment (“boarding
    team”) deployed from the Davis in a small boat and attempted
    to make contact with the Svesda Maru. The boarding team
    observed that the Svesda Maru was flying the Belizean flag.
    When the Svesda Maru did not respond after she was hailed
    by the Navy frigate, the Coast Guard team boarded the Svesda
    Maru and conducted a four-day search of the vessel including
    a “space accountability search.” The Davis’s boarding team
    was relieved by a second Coast Guard crew on the fifth day
    UNITED STATES v. ZAKHAROV                    18603
    of the search. The second crew discovered more than 9200
    kilograms of cocaine cleverly secreted in an area behind a fuel
    tank of the vessel.1
    Following discovery of the cocaine, the Coast Guard seized
    the Svesda Maru pursuant to our bilateral treaty with Belize
    and with the express permission of the Belizean government.
    The Svesda Maru’s crew, all Russians and Ukrainians, were
    taken into custody aboard the Coast Guard Cutter Active.
    They were kept together on the deck of the cutter for the ten
    days it took to reach San Diego, California. None of the
    Svesda Maru crewmen was interrogated while on board the
    Coast Guard ship.
    The cutter arrived in San Diego on May 13, 2001. Prior to
    Zakharov’s initial appearance before a magistrate judge, an
    agent of the United States Drug Enforcement Administration
    (“DEA”) interviewed him through a Russian interpreter. The
    agent advised Zakharov of his constitutional rights, and Zak-
    harov signed a Russian-language Miranda waiver. The inter-
    view lasted approximately one and one-half to two hours. The
    agent testified that Zakharov initially denied knowledge of the
    cocaine but was eventually persuaded to talk. Zakharov then
    admitted that he was to be paid $20,000 for the trip and that
    he and the crew knew that the vessel contained cocaine, but
    he claimed that only the captain knew all of the details of the
    voyage. He also claimed that this was his first experience
    smuggling cocaine.
    Later that day, a federal magistrate judge found probable
    cause to support the complaint against Zakharov. Zakharov’s
    1
    This turned out to be one of the largest cocaine seizures in United
    States maritime history. See Press Release, Office of National Drug Con-
    trol Policy, White House Drug Policy Office and Coast Guard Announce
    All-Time Record Annual Maritime Cocaine Seizures (Oct. 5, 2001), avail-
    able       at      http://www.whitehousedrugpolicy.gov/NEWS/press01/
    100501.html.
    18604              UNITED STATES v. ZAKHAROV
    initial appearance in court was on the following day. The
    magistrate ordered his detention without bail. Zakharov was
    indicted on May 24, 2001, and he pled not guilty to one count
    of conspiracy to possess cocaine with intent to distribute
    aboard a vessel and one count of possession of cocaine with
    intent to distribute aboard a vessel, in violation of the
    MDLEA, 46 U.S.C. app. § 1903(a), (c)(1)(C), (f) & (j), and
    18 U.S.C. § 2. In November 2002, a jury in the Southern Dis-
    trict of California convicted Zakharov on both counts. He was
    sentenced to 240 months in custody to be followed by five
    years of supervised release.
    II
    Zakharov first argues that the district court lacked jurisdic-
    tion to adjudicate his claims under the MDLEA. He claims
    that (1) the district court erred in failing to submit facts neces-
    sary to establish jurisdiction to the jury, and (2) the govern-
    ment failed to present sufficient evidence to establish a nexus
    between the United States and the seized cocaine.
    [1] The MDLEA prohibits drug smuggling activity by “any
    person on board a vessel of the United States, or on board a
    vessel subject to the jurisdiction of the United States, or who
    is a citizen of the United States or a resident alien of the
    United States on board any vessel.” 46 U.S.C. app. § 1903(a).
    The statute provides:
    Jurisdiction of the United States with respect to ves-
    sels subject to this chapter is not an element of any
    offense. All jurisdictional issues arising under this
    chapter are preliminary questions of law to be deter-
    mined solely by the trial judge.
    
    Id. § 1903(f).
    In United States v. Klimavicius-Viloria, 
    144 F.3d 1249
    , 1257 (9th Cir. 1998), we distinguished between
    “statutory jurisdiction” and the nexus requirement of “consti-
    tutional jurisdiction.” A court determines statutory jurisdic-
    UNITED STATES v. ZAKHAROV                        18605
    tion by asking whether the vessel at issue is “a vessel subject
    to the jurisdiction of the United States,” which MDLEA
    defines according to the ship’s nationality (if any), its loca-
    tion, and any relevant agreements between the United States
    and foreign nations regarding the enforcement of United
    States criminal laws on vessels or in territorial waters subject
    to the nation’s jurisdiction. See 46 app. U.S.C. § 1903(c). In
    contrast, a court determines constitutional jurisdiction based
    on the nexus between the United States and the attempted
    criminal transaction. See 
    Klimavicius-Viloria, 144 F.3d at 1257
    . Both jurisdictional inquiries must be satisfied “where
    the MDLEA is being applied extraterritorially.” United States
    v. Perlaza, 
    439 F.3d 1149
    , 1160 (9th Cir. 2006).
    Zakharov argues that § 1903(f) violates the Fifth and Sixth
    Amendments of the United States Constitution and the
    requirement of Apprendi v. New Jersey, 
    530 U.S. 466
    , 483-
    84, 499-500 (2000), that all facts necessary to constitute a
    statutory offense must be proven to a jury beyond a reason-
    able doubt. He asserts that Congress cannot “define away
    facts necessary to constitute a criminal offense” by labeling
    certain facts as non-elements of the crime. He argues that, by
    adopting § 1903(f), Congress impermissibly removed factual
    questions of statutory and constitutional nexus jurisdiction
    from the hands of the jury. We review de novo questions
    regarding the constitutionality of a statute. See United States
    v. Bynum, 
    327 F.3d 986
    , 990 (9th Cir. 2003).
    [2] In Perlaza we made clear that, notwithstanding
    § 1903(f), contested facts underlying the existence of statu-
    tory jurisdiction must be resolved by a jury.2 Perlaza, 439
    2
    Perlaza’s holding that a jury must resolve contested jurisdictional
    issues was limited to the context of statutory jurisdiction. We indicated
    that constitutional nexus jurisdiction is still an issue for the court’s deter-
    mination. 
    Perlaza, 439 F.3d at 1167
    (“[S]hould a jury conclude on remand
    that the [vessel was foreign], the district court will . . . have to determine
    whether the Government established a sufficient nexus between the [ves-
    sel] and the United States.” (emphasis added)).
    18606                UNITED STATES v. ZAKHAROV
    F.3d at 1165-67. We ruled in light of the Fifth and Sixth
    Amendments that such facts though “not formally identified
    as elements of the offense charged must be submitted to the
    jury and proved beyond a reasonable doubt.” 
    Id. at 1166
    (cita-
    tion and quotation omitted). Accordingly, insofar as Zakharov
    claims that statutory jurisdiction is an element of the crime
    that must be proven to the jury, that argument is now moot.
    Moreover, there is no factual question pertaining to statutory
    jurisdiction for the jury to decide. There is no dispute for pur-
    poses of § 1903 that the district court possessed statutory
    jurisdiction in the instant action: the Svesda Maru was a
    Belizean-flagged vessel registered in Belize, and the Coast
    Guard received consent to enforce United States law aboard
    her both expressly from the Belizean government and pursu-
    ant to our bilateral treaty with Belize.3 See 
    id. at 1168;
    46
    U.S.C. app. § 1903(c)(1)(C) (extending statutory jurisdiction
    to “a vessel registered in a foreign nation where the flag
    nation has consented or waived objection to the enforcement
    of United States law by the United States”).
    [3] Unlike statutory jurisdiction, the constitutional nexus
    requirement is not an express element of the crime but is “a
    judicial gloss applied to ensure that a defendant is not improp-
    erly haled before a court for trial.” 
    Klimavicius-Viloria, 144 F.3d at 1257
    . To accord with due process, we require a suffi-
    cient nexus between the United States and the defendant’s
    activities before exerting jurisdiction over foreign vessels.4
    See 
    Perlaza, 439 F.3d at 1168
    ; see also 
    Moreno-Morillo, 334 F.3d at 827-28
    ; 
    Klimavicius-Viloria, 144 F.3d at 1256-59
    ;
    United States v. Medjuck, 
    48 F.3d 1107
    , 1111 (9th Cir. 1995);
    3
    The district court “preliminarily” found statutory jurisdiction to be
    proper. Because it believed statutory jurisdiction to be an element of an
    offense under United States v. Smith, 
    282 F.3d 758
    (9th Cir. 2002), the
    court then submitted the question of consent to the jury. The district court
    need not have taken this second step since consent was uncontested.
    4
    We do not require nexus for stateless vessels. See 
    Perlaza, 439 F.3d at 1161
    ; United States v. Moreno-Morillo, 
    334 F.3d 819
    , 829 (9th Cir.
    2003).
    UNITED STATES v. ZAKHAROV                       18607
    United States v. Khan, 
    35 F.3d 426
    , 429-30 (9th Cir. 1994);
    United States v. Davis, 
    905 F.2d 245
    , 248-49 (9th Cir. 1990).
    Nexus is a constitutional requirement analogous to “minimum
    contacts” in personal jurisdiction analysis. Klimavicius-
    
    Viloria, 144 F.3d at 1257
    . Nexus has been treated as a non-
    element of an offense both before and after Apprendi, 
    530 U.S. 466
    . See 
    Bynum, 327 F.3d at 992-93
    (considering
    Apprendi and stating that “if a statute does not expressly
    require proof of a nexus between the criminal conduct and the
    United States, proof of such a connection is not an element of
    the offense” (citation omitted)); 
    Klimavicius-Viloria, 144 F.3d at 1257
    (“Nexus is part of the jurisdictional inquiry, but it is
    an inquiry for the court, not the jury.”).
    [4] In this context, MDLEA § 1903(f) merely codified this
    court’s longstanding rule that the constitutional nexus inquiry
    is a matter for the court’s determination. See id.; Moreno-
    
    Morillo, 334 F.3d at 827-28
    (citing Klimavicius-Viloria and
    holding that, in the context of the MDLEA, nexus is an
    inquiry for the court, not the jury). Accordingly, we reject
    Zakharov’s contention that the constitutional nexus inquiry
    must be submitted to a jury.
    [5] The next question is whether the district court properly
    determined that the evidence sufficed to establish a nexus
    between the United States and Zakharov’s activities. See
    
    Klimavicius-Viloria, 144 F.3d at 1257
    -59. Due process
    requires a district court to find sufficient nexus even when the
    flag nation has consented to the application of United States
    law.5 See 
    Perlaza, 439 F.3d at 1168
    . Nexus may be estab-
    5
    The First and Fifth Circuits have rejected the position that nexus is
    required for foreign vessels when the flag nation has consented to the
    application of United States law to the defendants. See United States v.
    Bustos-Useche, 
    273 F.3d 622
    , 627-28 (5th Cir. 2001) (holding that juris-
    dictional requirements were met because the flag nation consented to the
    enforcement of the MDLEA over the foreign vessel); United States v. Car-
    dales, 
    168 F.3d 548
    , 552-53 (1st Cir. 1999) (stating that due process is not
    18608                 UNITED STATES v. ZAKHAROV
    lished by a showing that “an attempted transaction is aimed
    at causing criminal acts within the United States” or that “the
    plan for shipping the drugs was likely to have effects in the
    United States.” United States v. Medjuck, 
    156 F.3d 916
    , 919
    (9th Cir. 1998) (citing 
    Klimavicius-Viloria, 144 F.3d at 1257
    ).
    In Klimavicius-Viloria, we considered that (1) the markings
    on the seized cocaine matched markings in a database of other
    cocaine seized in the United States; (2) the United States was
    the most likely destination for a large load of cocaine; and (3)
    the location of the vessel and the maps on board were consis-
    tent with a course bound for the United 
    States. 144 F.3d at 1258-59
    .
    Here, extensive evidentiary hearings were held to deter-
    mine whether sufficient nexus with the United States existed
    to establish jurisdiction. The district court determined by a
    preponderance of the evidence that the shipment of cocaine
    was likely to have effects in the United States. The court
    found that (1) four of the twelve markings on the cocaine bun-
    dles were found previously in the United States; (2) based on
    the type of vessel, its location, and the kinds of navigational
    charts on the vessel, the cocaine was destined for the United
    States; and (3) it was unlikely that Russia or Europe was the
    intended destination for the cocaine. The district court based
    violated because it is not arbitrary or fundamentally unfair to exert author-
    ity with the flag nation’s consent).
    The Third Circuit has rejected the proposition that nexus is required
    without expressly distinguishing between stateless and foreign vessels. See
    United States v. Martinez-Hidalgo, 
    993 F.2d 1052
    , 1056 (3d Cir. 1993)
    (holding that no nexus was required in a determination involving a state-
    less vessel); see also United States v. Perez Oviedo, 
    281 F.3d 400
    , 403 (3d
    Cir. 2002) (noting that Martinez-Hidalgo had expressly rejected our
    approach and holding that it was not arbitrary or fundamentally unfair to
    exert jurisdiction when the flag nation consents to application of the
    MDLEA).
    Unless and until the Supreme Court addresses this issue, we are bound
    by Ninth Circuit precedent.
    UNITED STATES v. ZAKHAROV                      18609
    the last two findings on its determination that the testimony
    of Zakharov’s expert witness, a former DEA agent, was not
    as credible or persuasive as that of the government’s expert,
    a DEA strategic intelligence analyst with over eighteen years
    of experience. See Spain v. Rushen, 
    883 F.2d 712
    , 717 (9th
    Cir. 1989) (“ ‘[W]hen a trial judge’s finding is based on his
    decision to credit the testimony of one of two or more wit-
    nesses, each of whom has told a coherent and facially plausi-
    ble story that is not contradicted by extrinsic evidence, that
    finding, if not internally inconsistent, can virtually never be
    clear error.’ ” (quoting Anderson v. Bessemer City, 
    470 U.S. 564
    , 575 (1984))).
    Zakharov makes very specific evidentiary challenges to the
    district court’s findings and questions its credibility determi-
    nation. Zakharov suggests that, because the government’s
    expert testified that Russia also has a drug trafficking market
    and that Europe was a possible market, it was erroneous for
    the district court to believe that the United States was the
    likely destination for the drugs. But many of the statements on
    which Zakharov relies could support either witness’s conclu-
    sion.6 In essence, Zakharov’s claim constitutes no more than
    an argument that it would have been reasonable for the district
    court to believe his expert witness instead of the expert wit-
    ness for the United States. Zakharov’s argument does not
    create “a definite and firm conviction that a mistake has been
    committed” by the district court in its credibility and factual
    findings. Silva v. Woodford, 
    279 F.3d 825
    , 835 (9th Cir. 2002)
    6
    For example, Zakharov points out that the government’s expert testi-
    fied that, “between 1998-2000, the number of seizures of cocaine had
    increased over 100% in the Eastern Pacific (where the Svesda Maru was
    seized) and that cocaine seizures in the Caribbean had decreased while sei-
    zures at the United States/Mexico border had decreased.” This fact could
    show that more shipments were going to places other than the United
    States. However, it could just as reasonably suggest that smugglers were
    attempting more sea-based imports into the United States and fewer land-
    based attempts along the border.
    18610             UNITED STATES v. ZAKHAROV
    (quotation and citation omitted). Thus, the district court did
    not err.
    Next, we must determine whether these facts support a
    finding that the drug shipment would likely have had effects
    in the United States. The only significant distinction between
    the facts establishing nexus in Klimavicius-Viloria and those
    in the instant case is that here there are fewer cocaine bundle
    markings that match bundles found previously in the United
    States. We considered matching markings to be “[t]he most
    persuasive evidence” in 
    Klimavicius-Viloria. 144 F.3d at 1258
    . There, five of the markings had been found only in the
    United States, while five others had been found predomi-
    nately in the United States and in countries involved in the
    shipment of cocaine. 
    Id. Further, “three
    sets of the markings
    have been found together in seizures in the United States.” 
    Id. The connection
    is not as substantial here. Only four of the
    twelve markings had been found previously in the United
    States. Three of the matches may have been particularly sig-
    nificant, however, because they were found on cocaine pack-
    ages in the United States roughly contemporaneously with the
    seizure of the Svesda Maru.
    [6] In any event, the location of the vessel, the large
    amount of cocaine, the types of navigational charts on board,
    and the existence of some matching logos are sufficient indi-
    cators of nexus for the exercise of United States jurisdiction
    to “not be arbitrary or fundamentally unfair.” See 
    id. at 1256
    (citing 
    Davis, 905 F.2d at 248-49
    ). We hold that the district
    court properly found sufficient nexus between the United
    States and the seized cocaine to support its jurisdiction.
    III
    Zakharov contends that evidence of his statements made
    upon arrival in San Diego should be suppressed because there
    was undue delay in determining probable cause in violation of
    UNITED STATES v. ZAKHAROV                18611
    the Fourth Amendment and in bringing Zakharov before a
    magistrate judge in violation of Federal Rule of Criminal Pro-
    cedure 5(a). We review de novo a district court’s denial of a
    motion to suppress evidence, but the factual findings underly-
    ing the ruling are reviewed for clear error. United States v.
    Fernandez-Castillo, 
    324 F.3d 1114
    , 1117 (9th Cir. 2003). We
    review for clear error the district court’s determination that
    pre-arraignment delay is reasonable under Rule 5(a). See
    United States v. Padilla-Mendoza, 
    157 F.3d 730
    , 732 (9th Cir.
    1998).
    [7] Zakharov claims that the United States’ failure to utilize
    helicopters, radios, fax machines, and other technology to
    obtain a probable cause determination before he was physi-
    cally present in the United States constituted undue delay
    under the Fourth Amendment. The district court summarily
    held that Zakharov could not “prevail on the Fourth Amend-
    ment claim because the Fourth Amendment does not apply to
    aliens outside United States territory.” In support the court
    cited United States v. Verdugo-Urquidez, 
    494 U.S. 259
    (1990), in which the Supreme Court held that the Fourth
    Amendment does not apply to searches and seizures by the
    United States against a non-resident alien in a foreign country.
    See 
    id. at 274-75;
    see also 
    id. at 271
    (“[A]liens receive consti-
    tutional protections when they have come within the territory
    of the United States and developed substantial connections
    with this country.” (citation omitted)). The Verdugo-Urquidez
    court noted that a warrant requirement for overseas searches
    “could significantly disrupt the ability of the political
    branches to respond to foreign situations involving our
    national interest.” 
    Id. at 273-74.
    [8] This holding forecloses Zakharov’s claim. Here, the
    alleged unconstitutional delay took place outside of the
    United States in international waters, and there is no sugges-
    tion that Zakharov had any substantial connection to this
    country. See United States v. Barona, 
    56 F.3d 1087
    , 1093-94
    (9th Cir. 1995) (holding that Fourth Amendment protection
    18612             UNITED STATES v. ZAKHAROV
    does not apply to an alien until he “has assumed the complete
    range of obligations that we impose on the citizenry” (quota-
    tion and citation omitted)). Because Zakharov cannot show
    that he is one of the “People of the United States,” 
    id. at 1093
    (quotation and citation omitted), he is not entitled to protec-
    tion under the Fourth Amendment.
    [9] We also hold that Zakharov’s claim pursuant to Federal
    Rule of Criminal Procedure 5(a) is without merit. At the time
    of Zakharov’s arrest, Rule 5(a) provided that “any person
    making an arrest without a warrant shall take the arrested per-
    son without unnecessary delay before the nearest available
    federal magistrate judge.” Fed. R. Crim. P. 5(a) (2001). The
    district court held the delay justified by the need to transport
    Zakharov 1620 nautical miles to the United States. The dis-
    trict court found that “[w]ith the Svesda Maru in tow, the
    ships proceeded to the nearest United States port, San Diego,
    and made no stops along the way.” A federal magistrate judge
    found probable cause to support the complaint filed against
    Zakharov the day that he arrived in San Diego. The district
    court’s finding that Zakharov was presented to the magistrate
    without unnecessary delay was not clearly erroneous, and we
    affirm its ruling.
    IV
    Zakharov asserts that the government failed to present suf-
    ficient evidence to sustain his convictions. We review de novo
    the district court’s denial of a motion for acquittal under Fed-
    eral Rule of Criminal Procedure 29. United States v. Johnson,
    
    357 F.3d 980
    , 983 (9th Cir. 2004). We review evidence pre-
    sented against the defendant in “the light most favorable to
    the [g]overnment” to determine “whether any rational trier of
    fact could have found the essential elements of the crime
    beyond a reasonable doubt.” 
    Id. (citation and
    quotation omit-
    ted).
    [10] “To prove a conviction for conspiracy, the government
    must establish that [the defendant] ‘had knowledge of the
    UNITED STATES v. ZAKHAROV               18613
    conspiracy and acted in furtherance of it.’ ” United States v.
    Messer, 
    197 F.3d 330
    , 341 (9th Cir. 1999) (quoting United
    States v. Wiseman, 
    25 F.3d 862
    , 865 (9th Cir. 1994) (citations,
    quotation, and emphasis omitted)). Where evidence estab-
    lishes the existence of a conspiracy, that evidence suffices to
    support a conviction “if the government is able to establish
    even a slight connection with the conspiracy beyond a reason-
    able doubt.” 
    Id. Conviction for
    the underlying substantive crime of posses-
    sion of cocaine with intent to distribute aboard a vessel may
    be based on aider and abettor liability. 
    Klimavicius-Viloria, 144 F.3d at 1263
    . We may infer specific intent to distribute
    from a large quantity of cocaine. 
    Id. The United
    States “must
    show more than mere participation; the defendant must inten-
    tionally assist in the venture’s illegal purpose.” 
    Id. (quotation, citation,
    and alteration omitted). Knowing participation may
    be established by factors including:
    a long voyage on a small vessel evincing a close
    relationship between captain and crew; suspicious
    behavior or diversionary maneuvers before appre-
    hension; attempts to flee; inculpatory statements
    made after apprehension; witnessed participation as
    a crewman; obviousness of the contraband; or
    absence of equipment necessary to the intended use
    of the vessel.
    
    Perlaza, 439 F.3d at 1175
    (quoting 
    Klimavicius-Viloria, 144 F.3d at 1263
    ).
    [11] Zakharov’s convictions are clearly supported by suffi-
    cient evidence. Two DEA agents testified as to Zakharov’s
    statement that he was aware of the cocaine, that the entire
    crew had knowledge of the cocaine, and that they were to be
    paid $20,000 each for the voyage. This testimony, supported
    by the circumstantial evidence surrounding the seizure of
    cocaine on the Svesda Maru and other similar seizures, is suf-
    18614                UNITED STATES v. ZAKHAROV
    ficient to establish that a major drug-smuggling conspiracy
    existed and to show specific intent and knowing participation.
    Specifically, Zakharov was working on a fishing boat when
    it was readily apparent that the fishing vessel was not doing
    much fishing.7 See 
    Perlaza, 439 F.3d at 1175
    -76 (“[C]ourts
    have found knowing participation in a maritime narcotics-
    trafficking scheme when a ship’s asserted legitimate purpose
    appears to be a ruse.” (quoting 
    Klimavicius-Viloria, 144 F.3d at 1264
    ) (alteration omitted)). “[A]ny rational trier of fact
    could have found” the evidence sufficient to sustain Zak-
    harov’s convictions. 
    Id. at 1175
    (citation omitted).
    V
    Zakharov argues that the district court erred in determining
    his ineligibility for a minor role adjustment or for relief under
    the safety valve provision pursuant to 18 U.S.C. § 3553(f).
    We review both of these factual determinations for clear error.
    United States v. Rodriquez-Cruz, 
    255 F.3d 1054
    , 1060 (9th
    Cir. 2001) (minor role); United States v. Washman, 
    128 F.3d 1305
    , 1307 (9th Cir. 1997) (safety valve). The defendant
    holds the burden of demonstrating by a preponderance of the
    evidence that he qualifies for a minor role reduction or for
    safety valve treatment. United States v. Ladum, 
    141 F.3d 1328
    , 1348 (9th Cir. 1998); United States v. Ajugwo, 
    82 F.3d 925
    , 929 (9th Cir. 1996).
    The district court denied Zakharov’s request for a minor
    role adjustment because the offense involved a large quantity
    of drugs. We hold that the district court’s denial of the minor
    role adjustment was not clearly erroneous. The court reason-
    7
    The boarding team noted that (1) the bait aboard the ship was frozen
    solid and “appeared to have been there for quite a long time;” (2) there
    were only about twelve fish on board of the size that would normally be
    caught by professional fishermen; (3) the amount of fish on board was
    inconsistent with the time that the vessel had been underway; and (4) the
    large fish were frozen and in a decomposing state.
    UNITED STATES v. ZAKHAROV                18615
    ably concluded that persons assisting in the transportation of
    such a large quantity of cocaine generally do not play a minor
    role, particularly when the drugs are transported by sea. See
    United States v. Murillo, 
    255 F.3d 1169
    , 1179 (9th Cir. 2001).
    The district court similarly determined that Zakharov was
    not entitled to relief under the safety valve provision. The
    court explained that Zakharov did not sufficiently cooperate
    with the government and therefore failed to carry his burden
    that he told the government everything he knew about the
    offense pursuant to 18 U.S.C. § 3553(f)(5). Again, the court’s
    denial of Zakharov’s request for leniency was not clearly
    erroneous. See United States v. Arrington, 
    73 F.3d 144
    , 148
    (9th Cir. 1996).
    [12] We also note that the district court’s findings that Zak-
    harov did not cooperate with the government, and was there-
    fore ineligible for a reduced sentence under 18 U.S.C.
    § 3553(f), did not violate Zakharov’s Sixth Amendment
    rights. See United States v. Labrada-Bustamante, 
    428 F.3d 1252
    , 1262-63 (9th Cir. 2005) (holding that the “safety valve”
    provision of 18 U.S.C. § 3553(f) is not unconstitutional under
    Apprendi, 
    530 U.S. 466
    , or Blakely v. Washington, 
    542 U.S. 296
    (2004)). However, because we cannot reliably determine
    from the record whether the sentence would have been mate-
    rially different had the district court known that the Sentenc-
    ing Guidelines were advisory when the sentence was
    imposed, a limited remand is appropriate. See 
    Ameline, 409 F.3d at 1084-85
    .
    VI
    The MDLEA is constitutional as applied to Zakharov and
    did not change our longstanding rule that the constitutional
    nexus inquiry is a matter for the district court’s determination.
    The district court did not err in finding a sufficient nexus
    between the United States and Zakharov’s drug-smuggling
    activities. Therefore, its exercise of jurisdiction over Zak-
    18616             UNITED STATES v. ZAKHAROV
    harov comported with all due process requirements. Further-
    more, the district court properly denied Zakharov’s motion to
    suppress evidence of his confession, and sufficient evidence
    existed to support his convictions. We affirm Zakharov’s con-
    victions and grant a limited remand to permit the district court
    to reconsider the sentence pursuant to Ameline.
    Conviction AFFIRMED; sentence REMANDED.
