    Appeals from the United States District Court

    _________________________
    (February 10, 2011)
    Before DUBINA, Chief Judge, and ANDERSON, Circuit Judge.*
    *
    Although United States District Judge David H. Coar of the Northern District of Illinois sat
    by designation in this case, he retired as an Article III Judge in December 2010. Accordingly, we
    decide this case by a quorum. See 11th Cir. R. 34-2.
    DUBINA, Chief Judge:
    Appellants Ever Balbino Ibargüen-Mosquera (“Mosquera”), Efrain Cuero
    Portocarrero (“Portocarrero”), and Isaias Estupinan (“Estupinan”) (collectively,
    “Appellants”)1 appeal their respective convictions for both conspiring to violate
    and violating the Drug Trafficking Vessel Interdiction Act, 18 U.S.C. § 2285
    (2010) (the “DTVIA”). Appellants challenge their convictions under the DTVIA
    on five grounds. First, Appellants contend the DTVIA is unconstitutional on
    various grounds. Second, Appellants argue that convicting them of both
    conspiracy to violate and a substantive violation of a single statute runs afoul of
    the Constitution’s prohibition against double jeopardy.2 Third, Appellants argue
    the elements of statelessness and navigating through international waters, that the
    government had to prove, bear on culpability and thus are elements of the crime
    requiring proof beyond a reasonable doubt and proof of mens rea. Fourth,
    Appellants argue even if this court finds that the district court applied the elements
    of the DTVIA correctly, there was insufficient evidence to find them guilty of
    1
    There was a fourth crewmember-defendant named Johny Moriano Jiminez who did not
    appeal his conviction. We use the term “Defendants” to refer to all of the crewmembers in the
    original case, including Jiminez, while the term “Appellants” refers to only those Defendants who
    join in this appeal.

    Portocarrero does not join the other Appellants’ first two challenges.
    2
    violating the statute. Finally, Mosquera argues the district court erred when it
    excluded his expert witness’s testimony.
    After thorough review of the case and after hearing oral argument, we
    affirm the Appellants’ convictions.
    I. Background.
    A. Facts
    On the morning of January 8, 2009, the United States Coast Guard Ship
    ALERT (the “ALERT”) received a report from a Maritime Patrol Aircraft
    (“MPA”) that an unmarked semi-submersible vessel (the “Vessel”) was spotted in
    the Eastern Pacific Ocean, approximately 163 nautical-miles off the coast of
    Colombia. The Vessel was ocean-blue, 50 to 60 feet in length, and sat very low in
    the water. See app. A. The ALERT immediately dispatched to the location where
    the Vessel was originally spotted and arrived around 12 hours later.
    Before the ALERT arrived, the MPA observed four men exit the cabin, don
    life-vests, inflate life-rafts, and jump into the water. The Defendants then waited
    near the Vessel, which sat dead in the water. Eventually they deflated the rafts and
    resumed travel.
    The ALERT dispatched a helicopter to obtain infrared imagery of the Vessel
    when it neared the Vessel’s location. For an hour the helicopter covertly observed
    3
    the Vessel and noted that, on two occasions, the Vessel stopped and a Defendant
    exited the forward hatch and scanned the area before returning below deck. After
    observation, the Helicopter illuminated the Vessel and announced its presence; at
    around this time the ALERT dispatched a rescue team on a rigid-hull inflatable
    boat (the “Rescue”) to execute an interdiction.
    Once the helicopter illuminated the Vessel, the Defendants calmly exited the
    hatch, donned life-jackets, and inflated the life-rafts for a second time. One
    Defendant returned below deck, at which time helicopter personnel observed a
    “flash of light” and “smoke or steam” emit from the Vessel. After the Defendants
    jumped into the water, the Vessel sank.
    The Rescue arrived just as the boat was completely immersed. The Rescue
    crew escorted the Defendants back to the ALERT, where they were transferred to
    another U.S. Coast Guard ship, and eventually flown to Tampa, Florida. They
    arrived in Tampa on January 14, and were promptly arrested. Authorities
    interviewed each Defendant separately.
    B. Course of Proceedings and Disposition in the District Court.
    On January 13, 2009, a federal grand jury returned a two-count indictment
    charging Defendants with conspiring to operate or embark in a semi-submersible
    vessel in international waters, without nationality and with the intent to evade
    4
    detection, in violation of 18 U.S.C. § 2285, and operating, while aiding and
    abetting in the operation of, a semi-submersible vessel in international waters,
    without nationality and with the intent to evade detection, in violation of the
    DTVIA, 18 U.S.C. § 2285, and 18 U.S.C. § 2. Specifically, the DTVIA prohibits
    operat[ing] . . . or embark[ing] in any submersible vessel or semi-
    submersible vessel that is without nationality and that is navigating or
    has navigated into, through, or from waters beyond the outer limit of the
    territorial sea of a single country or a lateral limit of that country’s
    territorial sea with an adjacent country, with the intent to evade
    detection. . . .
    18 U.S.C. § 2285(a). Section 2, on the other hand, merely stands for the general
    principle that “[w]hoever commits an offense against the United States or aids,
    abets, counsels, commands, induces or procures its commission, is punishable as a
    principal.” Defendants entered a plea of not guilty and requested a bench trial.
    District Judge Lazzara, sitting as the fact-finder, found Defendants guilty of
    violating the DTVIA and sentenced each to 108 months’ imprisonment and 3 years
    supervised release for each count to run concurrently. Appellants timely appealed.
    II. Discussion.
    A. Appellants Challenges to the Constitutionality of the DTVIA.
    This case requires us to address de novo four constitutional challenges to the
    DTVIA in evaluating whether the district court properly denied Appellants’
    5
    motions to dismiss their indictments.3 Specifically, Appellants argue the DTVIA
    is unconstitutional because: (1) its enactment exceeds Congress’s power under
    Article I; (2) the phrases “semi-submersible vessel” and “intent to evade” are
    unconstitutionally vague; (3) it shifts the burden onto defendants to prove they are
    not engaging in drug trafficking and therefore denies them procedural due process;
    and (4) it is not rationally related to a legitimate government interest and therefore
    violates substantive due process. For the reasons stated below, we conclude that
    none of Appellants’ challenges have merit and thus affirm the district court’s
    denial of the motions to dismiss.
    1. Challenge that the DTVIA Exceeds Congressional Power.
    Article I, Section 8 of the Constitution grants Congress the power “[t]o
    define and punish Piracies and Felonies committed on the high Seas, and Offenses
    against the Law of Nations.” U.S. Const. art. I, § 8, cl. 10. This clause is a broad
    grant of power to Congress to punish offenses outside of the United States. Given
    that legislatures have plenary power to define the terms of criminal offenses,
    Chicago, Burlington, & Quincy Ry. Co. v. United States, 
    220 U.S. 559
    , 578–79, 31
    3
    “Generally, we review a district court’s denial of a motion to dismiss the indictment for
    abuse of discretion.” United States v. Di Pietro, 
    615 F.3d 1369
    , 1370 n.1 (11th Cir. 2010) (citing
    United States v. Palomino Garcia, 
    606 F.3d 1317
    , 1322 (11th Cir. 2010)). When a defendant
    challenges the constitutionality of a statute, however, the review is de novo. United States v.
    Spoerke, 
    568 F.3d 1236
    , 1244 (11th Cir. 2009).
    
    6 S. Ct. 612
    , 617 (1911), the question here is whether and in what circumstances
    Congress can grant extraterritorial jurisdiction over foreign defendants traveling
    outside of the United States’ territorial waters.
    The federal courts are in consensus on two basic restrictions to giving a law
    extraterritorial effect. First, Congress must state that it intends the law to have
    extraterritorial effect. See, e.g., United States v. Flores, 
    289 U.S. 137
    , 155, 53 S.
    Ct. 580, 584 (1933) (“[C]riminal statues of the United States are not by
    implication given extraterritorial effect.”). That requirement is clearly met here.
    18 U.S.C. § 2285(c) (“There is extraterritorial jurisdiction over an offense under
    this section. . . .”).
    Second, application of the law must comport with due process, meaning that
    application of the law “must not be arbitrary or fundamentally unfair.” United
    States v. Cardales, 
    168 F.3d 548
    , 553 (1st Cir. 1999); see also United States v.
    Howard-Arias, 
    679 F.2d 363
    , 371 (4th Cir. 1982) (principles of international law
    may give way to an extraterritorial federal statute, but that statute must still
    comport with due process); Leasco Data Processing Equip. Corp. v. Maxwell, 
    468 F.2d 1326
    , 1334 (2d Cir. 1972), abrogated on other grounds by Morrison v. Nat’l
    Australia Bank Ltd., __ U.S. __, 
    130 S. Ct. 2869
    (2010) (“If Congress has
    expressly prescribed a rule with respect to conduct outside the United States, . . . a
    7
    United States court would be bound to follow the Congressional direction unless
    this would violate the due process clause of the Fifth Amendment.”). In
    determining whether an extraterritorial law comports with due process, appellate
    courts often consult international law principles such as the objective principle,4
    the protective principle,5 or the territorial principle.6 See, e.g., United States v.
    Gonzalez, 
    776 F.2d 931
    , 938–41 (11th Cir. 1985) (relying on the protective
    principle to reject defendants’ arguments that applying the predecessor to the
    Maritime Drug Law Enforcement Act (the “MDLEA”) to them violated due
    4
    Under the objective principle, Congress may criminalize behavior that has a “nexus” to the
    United States. Section 18 of the Restatement (Second) of Foreign Relations provides:
    A state has jurisdiction to prescribe a rule of law attaching legal consequences to
    conduct that occurs outside its territory and causes an effect within its territory, if
    either
    (a) the conduct and its effect are generally recognized as constituent elements
    of a crime or tort under the law of states that have reasonably developed legal
    systems, or
    (b)(i) the conduct and its effect are constituent elements of activity to which
    the rule applies; (ii) the effect within the territory is substantial; (iii) it occurs as a
    direct and foreseeable result of the conduct outside the territory; and (iv) the rule is
    not inconsistent with principles of justice generally recognized by states that have
    reasonably developed legal systems.
    5
    Under the protective principle, Congress may criminalize behavior that may threaten the
    security of the United States. Section 33 of the Restatement (Second) of Foreign Relations provides
    in pertinent part:
    (1) A state has jurisdiction to prescribe a rule of law attaching legal consequences to
    conduct outside its territory that threatens its security as a state or the operation of its
    governmental functions, provided the conduct is generally recognized as a crime
    under the law of states that have reasonably developed legal systems. (emphasis
    added).
    6
    Under the territorial principle, a “state has jurisdiction to prescribe and enforce a rule of law
    in the territory of another state to the extent provided by international agreement with the other
    state.” 
    Cardales, 168 F.3d at 553
    (citation and internal quotation marks omitted).
    8
    process); United States v. Marino-Garcia, 
    679 F.2d 1373
    , 1380–83 (11th Cir.
    1982) (noting these as exceptions to the general prohibition against criminalizing
    conduct by foreigners outside of the United States); United States v. Suerte, 
    291 F.3d 366
    , 370 (5th Cir. 2002); 
    Cardales, 168 F.3d at 553
    . Appellants argue that
    DTVIA does not comport with due process because it fails to meet the nexus
    requirement (from the objective principle) or the requirement that the crime must
    be “condemned universally by law-abiding nations” (from the protective
    principle).
    These international law principles, however, only apply to laws that govern
    the conduct of flagged vessels. In the past we have held that the objective,
    protective, and territorial principles “have no applicability in connection with
    stateless vessels” because such vessels are “international pariahs” that have “no
    internationally recognized right to navigate freely on the high seas.” Marino-
    
    Garcia, 679 F.2d at 1382
    . Indeed, the law “places no restrictions upon a nation’s
    right to subject stateless vessels to its jurisdiction.” 
    Id. (emphasis added);
    see also
    United States v. Rendon, 
    354 F.3d 1320
    , 1325 (11th Cir. 2003) (“Because
    stateless vessels do not fall within the veil of another sovereign’s territorial
    protection, all nations can treat them as their own territory and subject them to
    their laws.” (citation and internal quotation marks omitted)); United States v.
    9
    Rubies, 
    612 F.2d 397
    , 403 (5th Cir. 1979);7 United States v. Dominquez, 
    604 F.2d 304
    , 307–09 (4th Cir. 1979). “We conclude, therefore, that international law
    permits any nation to subject stateless vessels on the high seas to its jurisdiction . .
    . . Jurisdiction exists solely as a consequence of the vessel’s status as stateless.”
    
    Marino-Garcia, 679 F.2d at 1383
    . Because extraterritorial jurisdiction is proper,
    we conclude that the enactment of the DTVIA does not offend the Due Process
    Clause of the Constitution.
    2. Void-for-Vagueness Challenge.
    Appellants also contend the DTVIA violates due process because the
    phrases “semi-submersible vessel” and “intent to evade” are vague and are thus
    subject to arbitrary enforcement. Except in First Amendment cases, a party “ ‘who
    engages in some conduct that is clearly proscribed cannot complain of the
    vagueness of the law as applied to the conduct of others.’ ” Holder v.
    Humanitarian Law Project, __ U.S. __, 
    130 S. Ct. 2705
    , 2719 (2010) (quoting
    Hoffman Estates v. Flipside, Hoffman Estates, Inc., 
    455 U.S. 489
    , 495, 
    102 S. Ct. 1186
    , 1191 (1982)). Therefore, we must determine whether these phrases are
    vague as applied to Appellants.
    7
    In Bonner v. City of Pritchard, 
    661 F.2d 1206
    , 1207 & 1209 (11th Cir. 1981) (en banc), the
    Eleventh Circuit adopted as binding precedent the decisions of the Fifth Circuit rendered prior to
    October 1, 1981.
    10
    First, the phrase “semi-submersible” clearly covers the Vessel here and thus
    is not vague. The DTVIA defines“semi-submersible” as “any watercraft
    constructed or adapted to be capable of operating with most of its hull and bulk
    under the surface of the water.” 46 U.S.C. § 70502(f)(1). Appellants argue that
    the terms “capable” and “most” are insufficiently clear to provide guidelines to
    law enforcement officials, and thus subject the DTVIA to arbitrary enforcement.
    Appellants’ Vessel, however, clearly falls within the DTVIA’s definition of semi-
    submersible under the plain English meaning of those terms.
    “Capable” means “having attributes required for performance, . . . having . .
    . features permitting, [or] having general . . . ability” to do something. Webster’s
    Ninth New Collegiate Dictionary 203 (1986). And “most” is a widely used term
    meaning “greatest amount.” 
    Id. at 774.
    The facts clearly show that this Vessel
    was operating only 4 to 12 inches above the water while stationary and was nearly
    completely underwater while moving. Since the Vessel was operating with the
    “greatest amount” of its bulk underwater at the time of detection, it clearly had
    “features permitting” it to do so. Therefore the phrase “semi-submersible vessel”
    covers the Vessel.
    Likewise, the phrase “intent to evade” clearly covers Appellants’ conduct
    and is not vague. Evade means “to elude by dexterity or stratagem.” Webster’s
    11
    Ninth New Collegiate Dictionary 429. Not only does the phrase “intent to evade”
    have a plain and ordinary meaning, the DTVIA defines that phrase by reference to
    another section of the code. In subsection (b), the DTVIA states that the presence
    of any of the indicia in 46 U.S.C. § 70507 (b)(1)(A), (E), (F), or (G), or (b)(4–6) is
    prima facie evidence of intent to evade detection.
    Appellants’ conduct is clearly covered under both the plain-English
    meaning of intent to evade and the relevant subsections. Defendants traveled in a
    Vessel that sat very low in the water, was painted ocean-blue, and had no head-
    lights or signals. Rather than using one of Colombia’s major ports to get the
    Vessel to sea, Defendants surreptitiously guided it down a small estuary near the
    Ecuadorian coast. The Vessel bore no registration numbers or other markings. It
    traveled more slowly in the day than at night, and was configured to create very
    little wake when moving and no wake when still. The Vessel sank upon arrival of
    the Rescue. There is sufficient evidence here that “intent to evade” covers
    Appellants’ conduct, and therefore that phrase is not vague as applied to them.
    Appellants additionally argue that because one of the § 70507 indicia of
    “intent to evade” is “the configuration of the vessel to ride low in the water or
    present a low hull profile to avoid being detected visually or by
    radar”—essentially the definition of semi-submersible—the statute is circular and
    12
    thus vague. This argument, however, has nothing to do with vagueness. What
    Appellants are actually arguing is that this provision violates due process because
    it shifts the burden of persuasion on the issue of “intent to evade” from the
    government to Appellants.
    Even as to this argument, however, Appellants fail. It is true that while
    Congress has the power to make the proof of one fact prima facie evidence of
    another, a statute may not “shift the burden of proof to the defendant by presuming
    [one element] upon proof of the other elements of the offense.” Patterson v. New
    York, 
    432 U.S. 197
    , 215, 
    97 S. Ct. 2319
    , 2329 (1977); see also United States v.
    Tinoco, 
    304 F.3d 1088
    , 1107 (11th Cir. 2002) (“[O]nce the legislature has defined
    certain facts as elements of the offense, the legislature cannot shift the burden of
    persuasion as to those elements to the defendant, nor can the legislature create any
    presumptions as to those elements that negate the defendant’s presumption of
    innocence.”). But this provision does not shift the burden onto Appellants for at
    least two reasons. First, that the design of the vessel can serve as prima facie
    evidence of intent to evade merely means that such evidence is legally sufficient to
    find such an intent, and does not shift the burden of persuasion onto Appellants.
    The government is still charged with convincing the fact-finder that the defendant
    intended to evade detection.
    13
    Second, there is much more evidence here of “intent to evade” than merely
    the fact that the Vessel is semi-submersible: the Vessel’s camouflage, its lack of
    headlights, its surreptitious route to the ocean, and its statelessness. The phrase
    “intent to evade detection” is therefore not vague, nor does it violate due process
    by presuming the element upon proof of another element of the crime.
    3. Procedural Due Process Challenge.
    Appellants argue that the DTVIA violates due process because it effectively
    redefines the offense of drug trafficking, eliminating the requirement of drug-
    possession. The Constitution prohibits presuming an ingredient of an offense
    upon proof of other facts, or shifting certain elements of an offense from an
    element to an affirmative defense. 
    Patterson, 432 U.S. at 215
    . The Constitution
    would therefore prohibit redefining an offense so that the absence of an element of
    the original crime becomes an affirmative defense.
    While it is probably true that the DTVIA was enacted in part to deal with
    the problem of losing drug evidence to the sinking of semi-submersibles, the
    DTVIA is not a drug-trafficking statute. In enacting the DTVIA, Congress chose
    to prohibit an entirely new evil, not to redefine an old one. Indeed, in discussing
    the enactment of the DTVIA, Congress considered that these vessels are useful not
    only in drug trafficking, but also in trafficking of weapons and people. 154 Cong.
    14
    Rec. H7,238–39 (daily ed. July 29, 2008) (statement of Rep. Steve Cohen); 154
    Cong. Rec. H10,253 (daily ed. Sept. 27, 2008) (statement of Rep. Daniel
    Lungren). Congress further found that other than these ills, these vessels have no
    utilitarian value to society. 154 Cong. Rec. H10,252–54 (daily ed. Sept. 27, 2008)
    (statement of Rep. Daniel Lungren). Based on these findings, Congress
    determined to criminalize not only the underlying conduct—whatever that conduct
    may be—but also traveling on the vessel itself.
    Appellants specifically argue that the DTVIA places the burden on them to
    prove that they are not trafficking drugs, but this is simply incorrect. Even if
    Appellants proved that they were not trafficking drugs, they would still be guilty
    of violating the DTVIA if the government proved, beyond a reasonable doubt, all
    of the elements of the crime.8 Because the DTVIA does not shift the burden of
    proof to the accused as to any element of the crime, but rather creates a wholly
    new crime that Congress is within its right to define, the Due Process Clause is not
    violated.
    4. Substantive Due Process Challenge.
    8
    Nor do the DTVIA’s affirmative defenses offer any support for Appellants’ claim. As an
    affirmative defense, a defendant can show that the vessel was, at the time of the offense: (A) a U.S.
    vessel or a vessel lawfully registered in a foreign country; (B) “classed by and designed in
    accordance with the rules of a classification society;” (C) operating in a government licensed
    activity; or (D) “equipped with and using” some sort of vessel monitoring system. 18 U.S.C. §
    2285(e). There is no defense if a defendant is found not to be trafficking in narcotics.
    15
    Appellants briefly argue that the DTVIA violates their substantive due
    process rights because it is not rationally related to any legitimate government
    interest. This is not a rigorous test and is generally easily met. We must simply
    determine whether “any set of facts may be reasonably conceived to justify
    legislation.” TRM, Inc. v. United States, 
    52 F.3d 941
    , 945 (11th Cir. 1995)
    (citation and quotation marks omitted).
    Congress has found that operating such vessels is a “serious international
    problem, facilitates transnational crime . . . and presents a specific threat to the
    safety of maritime navigation and the security of the United States.” 46 U.S.C. §
    70501. These types of ships have no utility other than the transport of drugs or
    weapons. 154 Cong. Rec. H10,252–54 (daily ed. Sept. 27, 2008) (statement of
    Rep. Daniel Lungren). They are capable of traveling long distances without
    refueling, are difficult to detect, and are easily disposable upon detection. Id.; 154
    Cong. Rec. H7,238–39 (daily ed. July 29, 2008) (statement of Rep. Steve Cohen).
    Clearly the government’s interest in eliminating the use of these types of vessels is
    legitimate, and the statute is narrowly tailored to suit that interest. Therefore
    Appellants’ substantive due process claim lacks merit.
    B. Double Jeopardy Claim.
    16
    Appellants also seek to invoke one of the three related protections afforded
    under the Fifth Amendment’s double jeopardy clause, that of prohibiting multiple
    punishments for the same offense. This court reviews de novo the district court’s
    denial of a motion to dismiss a charge on double jeopardy grounds. United States
    v. Thurston, 
    362 F.3d 1319
    , 1322 (11th Cir. 2004). In determining whether
    Appellants have been charged twice for the same offense, we apply the standard
    announced in Blockburger v. United States, which states that “where the same act
    or transaction constitutes a violation of two distinct statutory provisions, the test to
    be applied to determine whether there are two offenses or only one is whether each
    provision requires proof of an additional fact which the other does not.” 
    284 U.S. 299
    , 304, 
    52 S. Ct. 180
    , 182 (1932) (emphasis added).
    Ordinarily, the court must only look to the elements of each crime to
    determine whether there are two offenses or one. United States v. Hassoun, 
    476 F.3d 1181
    , 1186 (11th Cir. 2007). Moreover, it has long been held that when the
    conspiracy and substantive charges derive from separate statutes, “the
    commission of the substantive offense and a conspiracy to commit it are separate
    and distinct offenses” because the charge for conspiracy requires an element not
    17
    required by the substantive offense: proof of an agreement. Pinkerton v. United
    States, 
    328 U.S. 640
    , 643, 
    66 S. Ct. 1180
    , 1182 (1946).9
    We have previously held that where two counts are “charged under the same
    statutory provision,” Blockburger may require an inquiry beyond the elements of
    the offense to determine whether there are separate crimes “in substance as well as
    form.” 
    Hassoun, 476 F.3d at 1186
    . While the Government alleges that the “aiding
    and abetting” charge arises under both 18 U.S.C. §§ 2 & 2285, we have stated that
    § 2 “does not represent a distinct offense, but rather simply codifies an alternate
    theory of liability” that is inherent in every criminal charge. 
    Hassoun, 476 F.3d at 1184
    n.2. Therefore, the two charges both arise under the same statute, 18 U.S.C.
    § 2285.
    Even looking to the substance, however, it is clear there are two offenses
    here. The conspiracy charge requires collaboration on the part of the Defendants
    to violate the statute while the substantive crime contains no such requirement.
    Each Defendant admitted to agreeing with another person to embark on this trip.
    Each carried identification and some amount of cash. In order to further their goal
    of operating this Vessel, Defendants took turns navigating it. In order to further
    9
    One of the only notable exceptions to this rule is where the substantive offense requires the
    agreement of two or more parties, an exception not applicable in this case. United States v.
    Wayerski, 
    624 F.3d 1342
    (11th Cir. 2010).
    18
    their goal of evading detection, Defendants took turns scanning the horizon and
    looking for oncoming ships or planes. All of this shows that, above and beyond
    the elements of the DTVIA, the Defendants conspired to violate the DTVIA.
    Appellants argue, however, that the Blockburger rule should not even apply
    here because Congress did not intend to allow for cumulative punishment. The
    Blockburger rule, as a rule of statutory construction, is used to determine whether
    Congress intended that two offenses be punished cumulatively. 
    Hassoun, 476 F.3d at 1185
    (citing Albernaz v. United States, 
    450 U.S. 333
    , 337, 
    101 S. Ct. 1137
    ,
    1141 (1981)). Therefore, even if the Blockburger test is met, Congress may state
    that it does not intend cumulative punishment. Given the Federal Government’s
    long history of charging and convicting defendants of both conspiracies and
    substantive offenses, that the legislative history of DTVIA makes no mention of a
    desire to make each offense in that section exclusive, and that the DTVIA
    specifically provides for both a conspiracy charge and a substantive offense, we
    find this argument meritless.
    C. Statutory Construction Question.
    Appellants argue that the phrases “navigating . . . through, or from waters
    beyond the outer limit of the territorial sea of a single country or a lateral limit of
    that country’s territorial sea with an adjacent country” and “without nationality”
    19
    are elements of the crime which must be proved by the government beyond a
    reasonable doubt. Moreover, Appellants argue that the government must prove
    scienter—that is, Defendants knowingly acted with respect to these elements. This
    court reviews de novo issues of statutory construction. United States v. Svete, 
    556 F.3d 1157
    , 1161 (11th Cir. 2009) (en banc).
    We begin questions of statutory construction with the language of the
    statute. Hughes Aircraft Co. v. Jacobson, 
    525 U.S. 432
    , 438, 
    119 S. Ct. 755
    , 760
    (1999). The DTVIA prohibits
    operat[ing] . . . or embark[ing] in any submersible vessel or semi-
    submersible vessel that is without nationality and that is navigating or
    has navigated into, through, or from waters beyond the outer limit of the
    territorial sea of a single country or a lateral limit of that country’s
    territorial sea with an adjacent country, with the intent to evade
    detection. . . .
    18 U.S.C. § 2285(a). Moreover, subsection (g) of the DTVIA incorporates 46
    U.S.C. § 70504 of the MDLEA, which states, “Jurisdiction of the United States
    with respect to a vessel subject to this chapter is not an element of the offense.
    Jurisdictional issues arising under this chapter are preliminary questions of law to
    be determined solely by the trial judge.”10 Under this provision, provisions of the
    10
    We have previously upheld the constitutionality of removing these jurisdictional questions
    from the jury in the context of the MDLEA. See 
    Tinoco, 304 F.3d at 1108
    .
    20
    DTVIA that are solely jurisdictional are not elements going to culpability that
    must be proved to the fact-finder. Moreover, “ ‘the existence of the fact that
    confers . . . jurisdiction need not be one in the mind of the actor at the time he
    perpetrates the act made criminal by the federal statute.’ ” United States v.
    Campa, 
    529 F.3d 980
    , 1007 (11th Cir. 2008) (quoting United States v. Feola, 
    420 U.S. 671
    , 677 n.9, 
    95 S. Ct. 1255
    , 1260 n.9 (1975)). “[K]nowledge of
    jurisdictional facts is not required in determining guilt . . . .” 
    Id. (quoting United
    States v. Muncy, 
    526 F.2d 1261
    , 1264 (5th Cir. 1976)). Because Appellants
    concede that these elements bear at least partly on jurisdiction, we need only
    determine whether they are solely jurisdictional or bear simultaneously on
    jurisdiction and culpability.
    First, we hold that the phrase “navigating . . . through, or from waters
    beyond the outer limit of the territorial sea of a single country or a lateral limit of
    that country’s territorial sea with an adjacent country” is solely jurisdictional, and
    does not bear on culpability. The location of the commission of a crime is a
    jurisdictional fact in nearly all American laws. Indeed, crimes committed across
    state lines are often tried in federal courts and crimes committed in one state or
    intended to have an effect in a state are tried in that state’s courts. It is difficult, if
    not impossible, to imagine how changing the location of a crime bears on the
    21
    culpability of the defendant and, indeed, Appellants were unable to present a
    single reason why location would ever bear on culpability. We find it
    incomprehensible that a defendant found 11 miles from the coast of Colombia
    would necessarily be less culpable than a defendant found 13 miles from the same
    coast. We conclude, then, that this phrase bears solely on the jurisdiction of the
    United States and need not be proven beyond a reasonable doubt nor proven with
    scienter.
    We need not address, however, whether the “without nationality” element
    bears solely on jurisdiction or on jurisdiction and culpability. We conclude from
    the record that there is ample evidence that Appellants knew the Vessel was not
    registered in Colombia. The boat had no markings, registration papers, or flags,
    nor did it leave from any one of Colombia’s major ports. Because any error in
    interpretation would be harmless, we need not address this issue further.
    D. Sufficiency of the Evidence Claim.
    Appellants argue that the evidence was insufficient to convict them of
    violating the DTVIA.11 Primarily, Appellants argue that there is insufficient
    11
    Appellants essentially use this argument to rehash the argument that the term “knowingly”
    should apply to “that is without nationality” and “navigating . . . through, or from waters beyond the
    outer limit of the territorial sea of a single country or a lateral limit of that country’s territorial sea
    with an adjacent country.” Given our earlier conclusion that the “international waters” element goes
    to jurisdiction and not culpability, and that there is ample evidence that the Defendants knew the
    Vessel was stateless, we will not address the sufficiency challenge as to those elements here.
    22
    evidence to prove the crime of conspiracy and the element of “intent to evade
    detection.” This Court reviews de novo a challenge to the sufficiency of the
    evidence, “viewing the evidence in the light most favorable to the government.”
    United States v. Wright, 
    392 F.3d 1269
    , 1273 (11th Cir. 2004) (citation and
    quotation marks omitted). The question is whether “any rational trier of fact could
    have found the essential elements of the crime beyond a reasonable doubt.”
    Jackson v. Virginia, 
    443 U.S. 307
    , 319, 
    99 S. Ct. 2781
    , 2789 (1979).
    After a thorough review of the record, we first conclude that the evidence
    presented was more than legally sufficient to find that the Appellants had an
    “intent to evade.” Moreover, we conclude that there is sufficient evidence to
    prove that Appellants conspired to violate the DTVIA. To sustain a conviction for
    conspiracy, the government must prove (1) “the existence of an agreement to
    achieve an unlawful objective”; (2) “the defendant[s’] knowing and voluntary
    participation in the conspiracy”; and (3) “an overt act in furtherance of the
    conspiracy.” United States v. US Infrastructure, Inc., 
    576 F.3d 1195
    , 1203 (11th
    Cir. 2009). A conspiracy may, indeed usually must, be proven through
    circumstantial evidence. United States v. Gupta, 
    463 F.3d 1182
    , 1194 (11th Cir.
    2006). The fact-finder’s conclusion “should not be disturbed as long as it is
    23
    supported by the evidence.” United States v. Richardson, 
    532 F.3d 1279
    , 1284
    (11th Cir. 2008).
    By their own testimony, three of the four Defendants were recruited for this
    journey by the same man. They traveled together to the site of the Vessel near the
    Ecuador border. Two of the Defendants admitted that they knew such Vessels
    were commonly used for smuggling drugs. Each Defendant navigated the Vessel
    during their trip pursuant to instructions received via radio. Each Defendant had a
    specific “part” to play in the journey. Each carried a plastic bag carrying nearly
    identical contents: some form of identification and a large amount of U.S. and
    Colombian currency. This is certainly sufficient evidence that the Appellants
    engaged in a conspiracy to violate the DTVIA to warrant upholding the verdict of
    the fact-finder.
    E. Exclusion of Expert Testimony.
    Mosquera argues that the district court erred in excluding expert testimony
    that he claims would have aided in his defense that he did not knowingly travel
    into international waters. This court reviews a district court’s decision with
    respect to the admissibility of expert testimony for an abuse of discretion and can
    reverse the district court’s ruling only if it is manifestly erroneous. United States
    v. Frazier, 
    387 F.3d 1244
    , 1258 (11th Cir. 2004) (en banc).
    24
    Mosquera’s expert proposed to testify that, according to the Colombian
    Constitution, Colombia claims 200 nautical-miles off its coast as its territorial
    waters. Mosquera stipulated that he was not challenging the district court’s
    determination that the phrase “beyond the outer limit of the territorial sea of a
    single country” refers to the 12 nautical-miles recognized by the United States.
    Instead, the testimony served to show that it would be reasonable for Mosquera to
    believe that, at the time of interdiction, he was not in international waters. This,
    he argues, goes to the mental state of “knowing” he was navigating in
    international waters. Because we conclude that the phrase “navigating in
    international waters” goes to jurisdiction rather than culpability, this testimony
    was irrelevant and the district court did not abuse its discretion in refusing to
    admit it.
    III. Conclusion.
    Because we conclude that none of the Appellants’ arguments has merit, we
    affirm their convictions.
    AFFIRMED.
