BIRCH, Circuit Judge: Defendants-appellants Manuel Hernandez and Tito Daniel Estupinan appeal their convictions under the Maritime Drug Law Enforcement Act, 46 U.S.C. app. § 1901 et seq. (1994 & Supp. V 1999) (“MDLEA”). They were convicted of conspiracy to possess with intent to distribute five kilograms or more of cocaine while on board a vessel subject to the jurisdiction of the United States, in violation of 46 U.S.C. app. § 1903(a), (g), and (j), and of possession with intent to distribute five kilograms or more of cocaine while on board a vessel subject to the jurisdiction of the United States, in violation of 46 U.S.C. app. § 1903(a), (g) and 18 U.S.C. § 2 (2000). We AFFIRM their convictions. I. BACKGROUND A. Factual Background 1. The United States Coast Guard’s Interception of the Smuggling Vessel in International Waters On 18 June 2000, the United States Coast Guard cutter Thetis, a 270-foot ship with approximately 90 to 95 crew members, was on a counter-narcotics patrol in the eastern Pacific Ocean. During the patrol, the Thetis encountered a fiberglass vessel approximately 475 nautical miles west of the Columbian/Ecuadorian border in international waters. The vessel was approximately 40 feet in length,, equipped with three outboard motors, and low in profile to the water. Thetis crew members later testified that Coast Guard officials refer to such vessels as “go-fast” boats because they can travel at high rates of speed, which makes them a favored vehicle for drug and alien smuggling operations. When the crew first observed the vessel, it was approximately 300 miles from the nearest point of land. Randy Bradley, a law enforcement officer aboard the Thetis, later testified that this type of vessel, when used for recreational purposes, usually would stay within 20 nautical miles of the shore due to its limited fuel capacity. Using binoculars, Thetis crew members did not see any markings of identification or a flag on the vessel. The crew attempted to hail the vessel by way of radio communications in English and Spanish but received no response. As the Thetis proceeded towards the vessel, the Thetis crew launched a rigid-hull inflatable boat (“RHI”) that contained a four-person boarding team that was ordered to intercept and board the vessel. Once the RHI was in the water, the unresponsive vessel changed its previous course and began zigzagging to the left and to the right. While the RHI boarding team was attempting the interception, lookout officers aboard the Thetis observed four individuals on the zigzagging vessel. The individuals later were identified as Pedro Luis Christopher Tinoco, Neil Pomare Hoard, Manuel Hernandez, and Tito Daniel Estupinan, the four criminal defendants in this case. The Thetis lookout officers saw one defendant driving the vessel, one defendant walking back and forth on the vessel, and two defendants throwing overboard what were later identified as bales of cocaine and 55-gallon fuel drums. Due to the distance, the Thetis lookout officers were unable to see the faces of the defendants and thus were unable to identify which defendant was performing which activity as the RHI chased the zigzagging vessel. To locate the items thrown overboard by two of the defendants, the Thetis crew threw into the ocean two smoke floats, pyrotechnic devices that emit smoke for two to three hours when immersed in sea water. As they pursued the zigzagging vessel, the RHI boarding team, like the Thetis lookout officers, observed the defendants aboard the vessel dumping items into the ocean. They saw bales, fuel drums, wooden objects, and the vessel’s hatch being thrown overboard. As was true regarding the Thetis lookout officers, however, the RHI boarding team was unable to identify which of the four defendants were involved in dumping the items. Finally, after a 20 to 30 minute chase, the RHI was able to intercept the vessel. RHI Boarding Officers Tim Burke and Shelby Harrington then boarded the vessel and handcuffed the defendants. Officer Burke testified at trial that, once on board, he asked the vessel’s driver, later identified as Defendant Tinoco, about the vessel’s country of origin. Tinoco answered that the vessel was from Colombia. In a statement introduced by the defendants at trial, Officer Harrington stated that she spoke with the defendant later identified as Hoard, who told her that the vessel’s crew was from San Andreas, Colombia, and that the vessel was from Bue-na Venture, Colombia. Hoard also told her that the vessel was en route to the Galapagos Islands. When asked which of the four defendants was the vessel’s master, Hoard pointed to Tinoco. After Officers Burke and Harrington spoke with Tinoco and Hoard, the RHI boarding team conducted a search of the vessel. The passports of the four defendants were obtained. Despite a thorough search, however, the RHI boarding team was unable to find any identifying marks or registration documents that would confirm the claims made by Tinoco and Hoard that the vessel was Colombian in origin. The only other items found on board were spare engine parts, navigational and communication equipment, approximately 30 fuel drums, food and beverages, and clothing. Following the search of the vessel, the defendants were transferred to the Thetis cutter. Several members of the Thetis crew then proceeded to search the waters where the smoke floats had been thrown, using the vessel that had been seized to conduct the recovery operation. Approximately 97.5 wrapped bales were retrieved from the water. The bales subsequently were transferred to a Drug Enforcement Administration (“DEA”) warehouse in Miami, Florida. Scott Goodlin, a DEA forensic chemist, then sampled the bales and tested them for the presence of a controlled substance, finding that they contained cocaine. At trial, Goodlin estimated that, based on his sampling technique, the net weight of cocaine contained in the seized bales was 1,807 kilograms. The market value in the United States of this amount of cocaine, at the time the trial occurred, would have ranged from $12,000 to $29,000 per kilogram, according to the trial testimony of Adalberto Rivera, a drug agent at the Federal Bureau of Investigation (“FBI”). 2. The United States Coast Guard’s Communications with the Colombian Navy At the time the aforementioned events were occurring in the Eastern Pacific Ocean, a series of diplomatic communications took place between the Coast Guard and the Colombian, Navy. After RHI Boarding Officers Burke and Harrington spoke with Tinoco and Hoard about the nationality of the vessel and its crew, Officer Harrington relayed a radio communication to Christopher Barrows, an operations officer onboard the Thetis. She informed him about the verbal claims made by the defendants. that the vessel was from Colombia and that the crew was of Colombian nationality. The Coast Guard was to use this information to brief the Colombian Navy about the interception. After receiving the information from Officer Harrington, Officer Barrows communicated with, and sent a series of situation reports to, a Lieutenant Jelin from the Coast Guard District 11, who subsequently provided the information to the Coast Guard headquarters and the United States Department of State in Washington, D.C. Pursuant to the terms of the “Agreement between the Government of the United States of America and the Government of the Republic of Colombia to Suppress Illicit Traffic by Sea,” the Coast Guard then contacted the Colombian Navy, briefed it about the situation, and requested that the Colombian Navy attempt to verify the verbal claims by the defendants that their vessel was registered in Colombia. The purpose of these communications was to determine whether the vessel was a “vessel subject to the jurisdiction of the United States” as defined in the MDLEA, 46 U.S.C. app. § 1903(c), which would permit the United States to exercise jurisdiction over the case. Shortly thereafter, the Colombian Navy responded that it needed the name and registration number of the vessel before it could confirm or refute the verbal claims that the vessel was of Colombian origin. The Coast Guard then informed the Colombian Navy that it was unable to provide any additional information, given the absence of any identifying marks on the vessel and of any registration documents found on board. The Coast Guard also told the Colombian Navy that “the four crewman aboard the vessel refused to provide any information pertaining to their personal identification or that of the vessel.” Schultz Decl., R2-122 Exh. 20 at 3. Based on the information provided by the Coast Guard, the Colombian Navy stated that it was unable to confirm or refute the verbal claims made by the defendants that their vessel was of Colombian registry. As a result, the Coast Guard “assimilated the vessel to stateless status.” Id. In terms of the MDLEA, the vessel was treated as a “vessel without nationality,” as defined in § 1903(c)(2)(C), and thus as a “vessel subject to the jurisdiction of the United States” under 46 U.S.C. app. 1903(c)(1)(A). Accordingly, the four defendants were transported to the Middle District of Florida, Tampa Division, to face federal prosecution for the alleged drug smuggling operation. B. Indictment, Conviction, and Sentence On 19 July 2000, a federal grand jury returned a two-count superseding indictment against Tinoco, Hernandez, Estupi-nan, and Hoard, charging that they committed two offenses under the MDLEA, to wit: conspiracy to possess with intent to distribute five kilograms or more of cocaine while on board a vessel subject to the jurisdiction of the United States, in violation of 46 U.S.C. app. § 1903(a), (g), and (j) (Count I), and possession with intent to distribute five kilograms or more of cocaine while on board a vessel subject to the jurisdiction of the United States, in violation of 46 U.S.C. app. § 1903(a), (g) and 18 U.S.C. § 2 (Count II). The Defendants pled not guilty. In December of 2001, the four defendants were tried before a federal jury, and all four of them were convicted on both counts. Following the convictions, the district court meted out sentences for the drug trafficking operation.. The district court sentenced Hernandez to a term of 200 months of imprisonment and to 5 years of supervised release on each count, to run concurrently, and he was charged a $200 special assessment. The court sentenced Estupinan to a term of 252 months of imprisonment and to 5 years of supervised released on each count, to run concurrently, and he was charged a $200 special assessment. After imposition of sentence, Hernandez and Estupinan commenced this appeal to challenge their convictions. C. Issues on Appeal Appellants Hernandez and Estupinan raise numerous arguments as to why their convictions on both counts under the MDLEA should be overturned. The appellants raise two arguments premised on the United States Constitution. First, they contend that the MDLEA, 46 U.S.C. app. § 1903, is facially unconstitutional because its penalty provision, § 1903(g) — a provision that incorporates the penalties framework set forth in 21 U.S.C. § 960 (2000) — violates the dictates of Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435. (2000). Second, they challenge on constitutional grounds the jurisdiction and venue provision of the MDLEA, 46 U.S.C. app. § 1903(f), which requires that the issue of whether a vessel is subject to the jurisdiction of the United States be decided by the trial judge as a preliminary issue of law, rather than be submitted to the jury for proof beyond a reasonable doubt. The appellants assert that the jurisdiction and venue provision violates the principles enunciated in United States v. Gaudin, 515 U.S. 506, 115 S.Ct. 2310, 132 L.Ed.2d 444 (1995). The appellants raise several arguments in addition to their constitutionally based ones. They maintain that, even if it-was proper under 46 U.S.C. app. § 1903(f) for the district court to decide whether their vessel was subject to the jurisdiction of the United States, the court erred in concluding that the government met its evidentia-ry burden with respect to the jurisdictional issue in this case. The appellants also contend that the district court erred in denying their motion in limine to suppress the cocaine seized by the Coast Guard. Furthermore, they assert that the district court made several improper evidentiary rulings during the trial, the cumulative effect of which was reversible error, including: admitting the testimony of Officer Bradley and Agent Rivera as lay opinion testimony, when their testimony should have been considered expert testimony, thereby subjecting the government to the pretrial disclosure requirements of Federal Rule of Criminal Procedure 16(a)(1)(E); allowing government witnesses to use the phrase “go-fast” when discussing the appearance of the defendants’ vessel; and permitting testimony concerning the market value of the seized cocaine. Besides these arguments, the appellants challenge their convictions on the grounds that the district court erred in not granting their respective motions for judgment of acquittal under Rule 29. We will address each of these arguments in turn. II. DISCUSSION A. The Facial Constitutionality of Jp6 U.S.C. app. § 1903 in Light of the Apprendi Decision 1. The Statutory Framework In this subsection of our opinion, we analyze the effect of the Supreme Court’s Apprendi decision on the MDLEA, 46 U.S.C. app. § 1903, which contains a penalty provision, § 1903(g), that incorporates the penalties framework found in 21 U.S.C. § 960. In doing so, we begin with the language of § 1903. See United States v. Prather, 205 F.3d 1265, 1269 (11th Cir.), cert. denied, 531 U.S. 879, 121 S.Ct. 188, 148 L.Ed.2d 130 (2000). (“In interpreting the meaning of a statute, it is axiomatic that a court must begin with the plain language of the statute.”). Section 1903(a) of the Title 46 appendix defines the substantive offenses for which a defendant can be convicted under the MDLEA. The subsection provides: It is unlawful for 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, to knowingly or intentionally manufacture or distribute, or to possess with intent to manufacture or distribute, a controlled substance. 46 U.S.C. app. § 1903(a). The penalty provision for violations of § 1903 is contained in subsection (g). Section 1903(g), entitled “Penalties,” states that “[a]ny person who commits an offense defined in this section shall be punished in accordance with the penalties set forth in section 1010 of the Comprehensive Drug Abuse Prevention and Control Act of 1970 (21 U.S.C. [§ ]960).” 46 U.S.C. app. § 1903(g)(1). It follows that § 1903(g) incorporates by reference the penalties framework of 21 U.S.C. § 960. We address, then, the language of § 960. Section § 960(b), entitled “Penalties,” delineates a framework of penalties that vary depending on whether certain factors have been met in a particular drug case, such as the drug type and quantity involved. Section § 960(b) states in several places that a defendant is to be sentenced according to the penalties framework contained therein when a “violation” of § 960(a) has been proven. See 21 U.S.C. § 960(b)(1), (b)(2), (b)(3), (b)(4). The statutory language indicates that Congress intended for the factors listed in § 960(b) to serve as sentencing factors that come into play only upon a defendant’s conviction for a substantive offense under § 960(a). See United States v. Coy, 19 F.3d 629, 636-37 (11th Cir.1994) (per curiam). Thus, drug type and quantity are not elements of a substantive offense under 21 U.S.C. § 960(a), but instead are factors to be considered by the judge at sentencing under § 960(b). See id. at 637 (stating that “the quantity of drugs involved ... under ... § 960 is not an element of the offense that need be pled or proven at trial, but an issue for the court to determine at the sentencing phase”); cf. United States v. Sanchez, 269 F.3d 1250, 1266 (11th Cir.2001) (en banc), cert. denied, - U.S. -, 122 S.Ct. 1327, 152 L.Ed.2d 234 (2002) (“[Under 21 U.S.C. § 841,] neither the nature nor the quantity of [the] substance is an element of [the] offense that must be submitted to a jury or proved beyond a reasonable doubt. Instead, this Court [has] held that in order to obtain a conviction, the government need show only that some controlled substance was involved.”). By analogy, when we read 46 U.S.C. app. § 1903(a) in conjunction with 21 U.S.C. § 960(b), it is clear from the statutory language that Congress intended for § 1903(a) to state a complete substantive drug offense, without reference to drug type or quantity, and that Congress intended for the sentencing factors enunciated in § 960(b) to come into play only upon a defendant’s conviction for an offense under § 1903(a). Turning to a more detailed analysis of the sentencing factors found in 21 U.S.C. § 960(b), we point out that § 960(b) is divided into four sub-subsections, based on the quantity and type of drug involved. We discuss only the first three sub-subsections because the fourth sub-subsection is not applicable to cocaine, the controlled substance relevant to this case. The most severe penalties are found in § 960(b)(1), which provides for a statutory maximum of life imprisonment. Specifically, with reference to cocaine, § 960(b)(1) states that in cases that involve “5 kilograms or more of a mixture or substance containing a detectable amount of ... cocaine, ... the person committing such violation shall be sentenced to a term of imprisonment of not less than 10'years and not more than life.” 21 U.S.C. § 960(b)(l)(B)(ii). Section 960(b)(2), in turn, states that in cases that involve “500 grams or more of a mixture or substance containing a detectable amount of ... cocaine, ... the person committing such violation shall be sentenced to a term of imprisonment of not less than 5 years and not more than 40 years.” 21 U.S.C. § 960(b)(2)(B)(ii). In contrast to the first two sub-subsections, § 960(b)(3) is a catchall provision that provides for a term of imprisonment without reference to drug type or quantity. Cf. United States v. Trout, 68 F.3d 1276, 1280 (11th Cir.1995) (per curiam) (referring to the similarly worded 21 U.S.C. § 841(b)(1)(C) as a “catchall provision”). Section 960(b)(3) states that in cases that involve “a controlled substance in schedule I or II, ... the person committing such violation shall, except as provided in paragraphs (1), (2), and (4), be sentenced to a term of imprisonment of not more than 20 years.” 21 U.S.C. § 960(b)(3). Cocaine is a schedule II controlled substance. 21 U.S.C. § 812(a)(4) (Schedule II); 21 C.F.R. § 1308.12(b)(4). Thus, § 960(b)(3) provides a penalty for violations involving cocaine without regard to the drug quantity involved. 2. The Appellants’ Apprendi Argument Having laid out the, penalties framework set forth in 21 U.S.C. § 960(b), we turn to the appellants’ argument concerning its constitutionality, and by extension, the constitutionality of the MDLEA, 46 U.S.C. app. § 1903. In the present case, the four defendants filed a motion to dismiss the indictment, asserting that their indictment was premised on an unconstitutional statute. Specifically, they argued that the MDLEA is facially unconstitutional, given that it incorporates the penalties framework of 21 U.S.C. § 960(b), a framework that they contend violates the constitutional principles enunciated in the Supreme Court’s Apprendi decision. In Apprendi, the Supreme Court held that the Due Process Clause and the Sixth Amendment right to trial by jury require that “[o]ther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.” 530 U.S. at 490, 120 S.Ct. at 2362-63. “In federal prosecutions, such facts must also be charged in the indictment.” United States v. Cotton, 535 U.S. 625, 122 S.Ct. 1781, 1783, 152 L.Ed.2d 860 (2002). Rejecting the defendants’ motion to dismiss the indictment, the district court concluded that 21 U.S.C. § 960(b), and thus the MDLEA, did not violate these principles. On appeal, Hernandez and Estupinan begin their Apprendi argument by focusing on our precedent, which, as we have discussed, has treated the factors listed in 21 U.S.C. § 960(b) as sentencing factors, not as elements of an offense. See Coy, 19 F.3d at 636-37. Based on our precedent interpreting § 960(b) as setting forth sentencing factors for the judge to determine, the appellants contend that § 960 is unconstitutional under Apprendi because § 960(b) permits increases in the maximum penalty to which a defendant can be subjected without requiring that those factors be treated as elements of the substantive offense. That is, the appellants’ argument is that Apprendi mandates that the factors listed in § 960(b), such as drug type and quantity, must be charged in the indictment, submitted to the jury, and proven beyond a reasonable doubt. Because our precedent construes § 906(b) in a manner that rejects such an approach, the appellants contend that § 960 is facially unconstitutional by virtue of Apprendi. It follows, the appellants maintain, that the MDLEA, 46 U.S.C. app. § 1903, is facially unconstitutional, given that it incorporates by reference the penalties framework contained in 21 U.S.C. § 960. 3. The Effect of Our Sanchez Decision on Our Interpretation of 21 U.S.C. § 960 We review de novo the legal question of whether a statute is constitutional. United States v. Cespedes, 151 F.3d 1329, 1331 (11th Cir.1998). “We also review de novo the legal question of whether an indictment ... was insufficient under Apprendi, and we will reverse only if the Apprendi error was harmful.” United States v. Anderson, 289 F.3d 1321, 1325 (11th Cir.2002). Our review leads us to the conclusion that the appellants’ argument is untenable in light of our Sanchez decision, which involved a statutory framework analogous to the one in this case. In Sanchez, we addressed the constitutionality of 21 U.S.C. § 841 in light of Apprendi The language and structure of 21 U.S.C. § 841 is substantially similar to that of 21 U.S.C. § 960. See Coy, 19 F.3d at 636-37 (indicating that § 841 and § 960 are conceptually analogous and thus can be analyzed in the same manner). For instance, 21 U.S.C. § 841(a) sets forth a complete substantive drug offense, without reference to drug type or quantity, violations of which are punished under the penalties provided in § 841(b), in the same manner that 21 U.S.C. § 960(a) — as well as 46 U.S.C. app. § 1903(a) — set forth complete substantive drug offenses, without reference to drug type or quantity, violations of which are punished under the penalties provided in 21 U.S.C. § 960(b). See Sanchez, 269 F.3d at 1264-65 (discussing interplay between 21 U.S.C. § 841(a) and (b)). Additionally, the penalties framework found in § 841(b) is very similar to the framework found in § 960(b); indeed, the two provisions contain virtually identical language. Section 841(b)(1)(A) and (b)(1)(B), like § 960(b)(1) and (b)(2), set different terms of imprisonment, based on the specific quantity and drug type involved, with § 840(b)(1)(A) and § 960(b)(1) setting a maximum term of life imprisonment, and § 840(b)(1)(B) and § 960(b)(2) setting a maximum term of 40 years. See Sanchez, 269 F.3d at 1264-65 (discussing the penalties framework set forth in § 841(b)(1)(A) and (b)(1)(B)). Moreover, § 841(b)(1)(C), like § 960(b)(8), creates a catchall provision that sets a maximum term of 20 years imprisonment without reference to the drug type or quantity involved. See id. at 1265 (describing how § 821(b)(1)(C) serves as a catchall provision). Furthermore, as with § 960(b), our precedent consistently has construed § 841(b) as setting forth sentencing factors that are to be determined by the judge. See id. at 1266 n. 28 (listing cases). It follows that, because of the close similarity between the statutes involved, the Appren-di concerns raised in Sanchez mirror the concerns raised in the present case. We next address, therefore, our interpretation of Apprendi in the Sanchez case. In Sanchez, we interpreted the Appren-di decision narrowly, concluding that Ap-prendi did not blanketly overturn prior cases that construed 21 U.S.C. § 841(b) as setting forth sentencing factors for determination by the judge. Id. at 1268. Rather, we determined that Apprendi merely serves as “an external constitutional restraint under the Sixth Amendment and the Due Process Clause” that forbids the judge during sentencing from making findings that actually increase the defendant’s sentence above the prescribed statutory maximum. Id. This means that Apprendi “does not apply to the vast majority of sentencing scenarios,” where the sentence actually imposed “falls within the range prescribed by the statute for the crime of conviction.” Id. This also means that, in the context of federal drug cases, drug type and quantity do not have to be charged in the indictment or submitted to the jury for proof beyond a reasonable doubt, except when the finding of drug type or quantity causes the sentence actually imposed upon the defendant to rise above the prescribed statutory maximum. Id. at 1268-69. We then applied this reasoning to 21 U.S.C. § 841(b). We noted that § 841(b)(1)(C) “provides a statutory penalty range applicable to all drug offenses involving the controlled substances listed on schedules I or II without regard to drug quantity,” id. at 1268, and we consequently concluded that Apprendi does not apply when the defendant’s sentence falls into that statutory penalty range, meaning that there is no need to have drug quantity charged in the indictment, submitted to the jury, or proven beyond a reasonable doubt in that context, id. at 1269-70. We went on to rule that there is constitutional error under Apprendi in a 21 U.S.C. § 841 case only when the sentencing judge’s factual finding actually increased the defendant’s sentence above the statutory maximum found in § 841(b)(1)(C), and only when the fact that led to the enhanced sentence was not charged in the federal indictment or submitted to the jury for proof beyond a reasonable doubt. Id. at 1270. Applying this logic to 21 U.S.C. § 960(b), we point out that § 960(b)(3) “provides a statutory penalty range applicable to all drug offenses involving the controlled substances listed on schedules I or II without regard to drug quantity,” the maximum term of which is 20 years imprisonment. See Sanchez, 269 F.3d at 1268. Given that 21 U.S.C. § 960 has a catchall penalty provision, § 960(b)(3), there is no Apprendi constitutional error if the sentencing judge’s drug quantity finding led to the defendant receiving a sentence below the prescribed statutory maximum found in § 960(b)(3). See id. at 1269-70. There is constitutional error under Apprendi, moreover, in the 21 U.S.C. § 960 context only if the sentencing judge’s factual finding' actually increased the defendant’s sentence above the statutory maximum found in § 960(b)(3), and only if the fact that led to the enhanced sentence was not charged in the federal indictment or submitted to the jury for proof beyond a reasonable doubt. See id. 4. Application of These Principles to the Appellants’ Argument With these principles in mind, we reject the appellants’ facial challenge to 46 U.S.C. app. § 1903 under Apprendi. In so far as the appellants attack § 1903 as unconstitutional because it incorporates 21 U.S.C. § 960, they cannot demonstrate “that no set of circumstances exist under which the Act would be valid.” United States v. Mena, 863 F.2d 1522, 1527 (11th Cir.1989) (citation omitted). As we have explained, in most sentencing scenarios under 21 U.S.C. § 960, Apprendi is irrelevant because the sentence actually imposed will fall below the prescribed statutory maximum found in the catchall provision, § 960(b)(3). Indeed, the appellants’ circumstances in this case are examples of circumstances under § 960(b) that pass constitutional muster. With respect to Hernandez, he was sentenced to a term of 200 months (16.67 years) imprisonment, and so Ap-prendi is irrelevant to his case because his sentence falls below the 20-year statutory maximum found in § 960(b)(3). In contrast, Estupinan was sentenced to a term of 252 months (21 years), thereby placing his sentence above the § 960(b)(3) statutory ' maximum. Nevertheless, Estupinan’s situation is not an example of Apprendi constitutional error. Estupinan’s enhanced sentence resulted from the drug quantity that he was found to have possessed in this case, five or more kilograms of cocaine. See 21 U.S.C. § 960(b)(1)(B)(ii) (authorizing term of imprisonment between ten years and life when the conviction involves five or more kilograms of cocaine). Both counts of the superceding indictment in this case made reference to that particular drug quantity. The first count of the indictment charged that each of the four defendants, while on board a vessel subject to the jurisdiction of the United States, ... did knowingly and willfully conspire and agreé, with other persons, -both known and unknown to the grand jury, to knowingly and intentionally possess with the intent to distribute five (5) kilograms or more of a mixture or substance containing a detectable amount of cocaine, a controlled substance in violation of 46 U.S.C. app. § 1903(a), (g), and (j). R1-39 (emphasis added). The second count charged that each defendant, “while on board a vessel subject to the jurisdiction of the United States, ... did knowingly and intentionally possess with the intent to distribute, five (5) kilograms or more of a mixture or substance containing a detectable amount of cocaine, a controlled substance,” in violation of 46 U.S.C. app. § 1903(a), (g) and 18 U.S.C. § 2. Id. (emphasis added). The jury instructions also specifically referenced the drug quantity involved. Supp. R1-7-8. Additionally, in rendering its verdict, the jury made a special finding with respect to Estupinan that the drug quantity for which the he was being convicted was five or more kilograms of cocaine. R2-125. It follows that, even though Estupinan was sentenced to a term of imprisonment above the § 960(b)(3) statutory maximum, there was no Apprendi constitutional error because the drug quantity involved was charged in the federal indictment and submitted to the jury for proof beyond a reasonable doubt. In sum, the appellants have failed to demonstrate that Apprendi provides a basis for facially striking down 21 U.S.C. § 960 and, by extension, 46 U.S.C. app. § 1903; indeed, their own sentences are examples of situations where there is no Apprendi error in the § 960 and § 1903 contexts. B. The Constitutionality of 46 U.S.C. app. § 1903(f) in Light of the Gaudin Decision 1. The Statutory Framework In this subsection, we analyze the effect of the Supreme Court’s Gaudin decision on the constitutionality of the MDLEA jurisdiction and venue provision, 46 U.S.C. app. § 1903(f), which removes from the jury the question of whether a vessel is subject to the jurisdiction of the United States. As in the previous section, we begin with the language of the statute. See Prather, 205 F.3d at 1269. Section 1903(a), among other things, defines the substantive offense of “possession with intent to manufacture or distribute controlled substances on board vessels,” and, in so doing, states that such possession is unlawful when it occurs “on board a vessel subject to the jurisdiction of the United States.” 46 U.S.C. app. § 1903(a). Section 1903(c)(1)(A), in turn, states that a “vessel subject to the jurisdiction of the United States” includes a “a vessel without nationality.” 46 U.S.C. app. § 1903(c)(1)(A). A “vessel without nationality” is defined in § 1903(c)(2) as: (A) a vessel aboard which the master or person in charge makes a claim of registry, which claim is denied by the flag nation whose registry is claimed; (B) any vessel aboard which the master or person in charge fails, upon request of an officer of the United States empowered to enforce applicable provisions of United States law, to make a claim of nationality or registry for that vessel; and (C) a vessel aboard which the master or person in charge makes a claim of registry and the claimed nation of registry does not affirmatively and unequivocally assert that the vessel is of its nationality. 46 U.S.C. app. § 1903(c)(2). Building on this statutory framework, Congress amended the MDLEA in 1996, choosing to add a new subsection, § 1903(f), entitled “Jurisdiction and Venue.” See Coast Guard Authorization Act of 1996, Pub.L. 104-324, § 1138(a)(5), 110 Stat. 3901 (1996). Section 1903(f) provides that “^jurisdiction of the United States with respect to vessels subject to this chapter is not an element of any offense.” 46 U.S.C. app. § 1903(f). The section further states: “All jurisdictional issues arising under this chapter are preliminary questions of law to be determined solely by the trial judge.” Id. 2. The Appellants’ Argument In light of these statutory provisions, the four defendants filed another motion to dismiss the indictment, challenging the constitutionality of the MDLEA jurisdiction and venue provision, 46 U.S.C. app. § 1903(f). They also objected at trial to the district court’s decision to instruct the jury that the defendants’ vessel was subject to the jurisdiction of the United States as a matter of law. Essentially, the defendants argued that § 1903(f), by taking the jurisdictional issue away from the jury, violated the principles laid down in the Supreme Court’s Gaudin decision. Prior to Gaudin, the Supreme Court held that the Due Process Clause and the Sixth Amendment right to a jury trial provide a defendant who is charged with a serious offense with the constitutional right to insist that his guilt be determined beyond a reasonable doubt by a jury. Sullivan v. Louisiana, 508 U.S. 275, 277-78, 113 S.Ct. 2078, 2080-81, 124 L.Ed.2d 182 (1993); In re Winship, 397 U.S. 358, 364, 90 S.Ct. 1068, 1072-73, 25 L.Ed.2d 368 (1970). Reiterating these basic principles, the Supreme Court in Gaudin held that the Constitution “requirefs] criminal convictions to rest upon a jury determination that the defendant is guilty of every element of the crime with which he is charged, beyond a reasonable doubt.” 515 U.S. at 510, 115 S.Ct. at 2313. More specifically, the Gau-din Court held that if there are either factual questions or mixed questions of law and fact with respect to any element of an offense, the defendant has suffered an infringement upon his constitutional rights if those questions are not submitted to the jury for proof beyond a reasonable doubt. Id. at 511-15, 522-23, 115 S.Ct. at 2314-16, 2320. Finding that these principles were not violated by 46 U.S.C. app. § 1903(f), the district court denied the defendants’ motion to dismiss the indictment. At the close of the all the evidence at trial, the district court instructed the jury that the defendants’ vessel was subject to the jurisdiction of the United States as a matter of law. On appeal, Hernandez and Estupinan raise their Gaudin argument, contending that 46 U.S.C. app. § 1903(f) unconstitutionally removes from the jury the determination of whether the government has proven beyond a reasonable doubt that the vessel at issue in a given case is a vessel subject to the jurisdiction of the United States. To buttress their position, the appellants point to our decision in United States v. Medina, a decision that was handed down prior to the 1996 amendment of the MDLEA, in which we held that the jurisdictional issue in MDLEA cases is an element of a § 1903(a) offense, and, consequently, that whether a vessel is subject to the jurisdiction of the United States is a question of fact that the jury must decide. 90 F.3d 459, 463-64 (11th Cir.1996). The appellants further assert that Congress through amendment cannot simply label jurisdiction a non-element in § 1903(f). Rather, they contend that the structure of § 1903(a), which includes the phrase “a vessel subject to the jurisdiction of the United States” within its definition of an MDLEA offense, mandates that the jurisdictional question be treated as a substantive element of the offense that the jury must decide. Additionally, the appellants argue that once Congress required the government to prove that a vessel is subject to the jurisdiction of the United States before a conviction can be obtained, it necessarily created an offense element that cannot arbitrarily be removed from the jury. Finally, the appellants contend that, because the MDLEA jurisdictional issue is a fact-bound determination, Gaudin requires that it be submitted to the jury for proof beyond a reasonable doubt. 3. The Effect of the 1996 Amendment to the MDLEA on our Medina Decision Whether a provision of a statute is constitutional is a question of law that we review de novo. Cespedes, 151 F.3d at 1331. As we shall explain, the defendants’ Gaudin challenge to 46 U.S.C. app. § 1903(f) is misplaced. Our analysis begins with Medina, which the appellants reference in an effort to show that the Constitution requires that the jurisdictional requirement of the MDLEA be treated as an element of the offense that the jury has to decide. It is true that in Medina we concluded that the issue of whether a vessel is subject to the jurisdiction of the United States should be treated as an element of a § 1903(a) offense that has to be submitted to the jury and proven beyond a reasonable doubt. Medina, 90 F.3d at 463-64; see also United States v. Ayarzar-Garcia, 819 F.2d 1043, 1048-49 (11th Cir.1987) (holding that the jurisdictional requirement under 21 U.S.C. § 955a(a), the predecessor provision to 46 U.S.C. app. § 1903(a), was an element of the offense that had to be submitted to the jury and proven beyond a reasonable doubt). We reached this conclusion because the MDLEA jurisdictional language — “a vessel subject to the jurisdiction of the United States” — is included in the provision that defines MDLEA substantive offenses, 46 U.S.C. app. § 1903(a). Medina, 90 F.3d at 463-64. We concluded that Ayarzar-Garcia, 819 F.2d at 1048-49, which dealt with the predecessor statute to 46 U.S.C. app. § 1903, controlled our decision. Medina, 90 F.3d at 463-64. In that case, we treated the jurisdictional language contained in the provision that defined the crime as a substantive offense element that the government had to prove beyond a reasonable doubt to the jury. Id. Our Medina decision also contained more-abstract language that addressed the issue of when, generally speaking, statutory jurisdictional provisions should be submitted to the jury for proof beyond a reasonable doubt. We stated “that when a question — for example, whether a vessel is without nationality' — of federal subject-matter jurisdiction is intermeshed with questions on the merits of a case, the jurisdictional issue should be determined at trial (per Rule 29 or by jury).” Id. at 463; see also Ayarza-Garcia, 819 F.2d at 1048-49. Put another way, Medina stated that, in cases where questions of subject matter jurisdiction are inextricably interwoven with the substantive elements of a criminal offense, the issue of jurisdiction is one for the jury to decide. We have reached this same conclusion with regard to jurisdictional issues in other contexts as well. See United States v. Castleberry, 116 F.3d 1384, 1389 (11th Cir.1997) (indicating that the showing of an effect on interstate commerce is a substantive element of Hobbs Act offenses that must be decided by the jury); United States v. Perrin, 580 F.2d 730, 737 (5th Cir.1978) (indicating that the use of interstate facilities is a substantive element of Travel Act offenses that must be decided by the jury). The Medina decision, however, occurred in an atmosphere of congressional silence. At the time of the decision, Congress was silent as to whether the MDLEA jurisdictional requirement was a matter of subject matter jurisdiction as well as a substantive element of a 46 U.S.C. app. § 1903(a) offense. Congress had not yet added § 1903(f) to the MDLEA, and so we had to infer whether Congress intended for the jurisdictional question to constitute both a question of subject matter jurisdiction and an element of an MDLEA offense. We did this by analyzing the statutory structure, an analysis that was made somewhat easier as a result of our interpretation of the similarly worded predecessor statute in Ayarzar-Gareia. The proper inference to be drawn from that structure, however, was far from self-evident, for in cases preceding Medina, we called attention to the fact that there was conflicting circuit precedent over whether the MDLEA jurisdictional requirement, in addition to being a matter of subject matter jurisdiction, was meant to be a substantive element of the offense. See United States v. Rojas, 53 F.3d 1212, 1215 n. 2 (11th Cir.1995); Mena, 863 F.2d at 1532-33 & n. 8. From the foregoing discussion, it is clear that our Medina decision was a case about statutory construction, not about the limits of congressional power to define the elements of an offense, as the appellant would have us suppose. Because we decided that the statutory structure indicated that the jurisdictional question was meant to be treated as both a matter of subject matter jurisdiction and as an offense element, there was no need to discuss whether Congress, if it so chose, could mandate that the jurisdictional requirement be treated solely as a matter of subject matter jurisdiction. The situation has changed, however, since the time of Medina. The 1996 Amendment to the MDLEA removes the statutory ambiguity that existed at the time we rendered that decision. By adding to the MDLEA the jurisdiction and venue provision, 46 U.S.C. app. § 1903(f), Congress, as we have pointed out, plainly indicated that whether a vessel is subject to the jurisdiction of the United States is not an element of the offense, but instead is solely an issue of subject matter jurisdiction that should be treated as a preliminary question of law for the court’s determination. 46 U.S.C. app. § 1903(f). It is true beyond peradventure that Congress has the constitutional authority to “overrule” a court interpretation of a statute by amending the statute. Henderson v. Scientific-Atlanta, Inc., 971 F.2d 1567, 1571-72 (11th Cir.1992). As a result, we conclude that Congress, by amending 46 U.S.C. app. § 1903(f), effectively overruled our statutory construction of the § 1903 jurisdictional requirement in Medina. The statutory language of the MDLEA now unambiguously mandates that the jurisdictional requirement be treated only as a question of subject matter jurisdiction for the court to decide. Thus, we now must address the issue that did not arise in Medina: whether Congress can constitutionally provide that the MDLEA jurisdictional requirement is a non-element of the offense, thereby authorizing the judge to decide the issue, rather than the jury. 4. Limitations on the Congressional Power to Remove Issues from the Jury’s Determination We begin our constitutional analysis by noting that, “[wjithin broad constitutional limits, the definition of the elements of a criminal offense is entrusted to the legislature, particularly in the case of federal crimes, which are solely creatures of statute.” Sanchez, 269 F.3d at 1263 n. 20 (internal quotation marks and brackets omitted); see also Staples v. United States, 511 U.S. 600, 604, 114 S.Ct. 1793, 1796, 128 L.Ed.2d 608 (1994). The legislature’s decision on how to define the elements of the offense “is usually dispositive.” McMillan v. Pennsylvania, 477 U.S. 79, 85, 106 S.Ct. 2411, 2415, 91 L.Ed.2d 67 (1986); see also Gaudin, 515 U.S. at 525, 115 S.Ct. at 2321 (Rehnquist, J., concurring). For instance, legislatures have great leeway in deciding whether a particular factual issue constitutes an element of an offense to be proven by the government, or whether it should be treated as an affirmative defense to be proven by the criminal defendant. See Martin v. Ohio, 480 U.S. 228, 233, 107 S.Ct. 1098, 1101-02, 94 L.Ed.2d 267 (1987); Patterson v. New York, 432 U.S. 197, 210, 97 S.Ct. 2319, 2327, 53 L.Ed.2d 281 (1977). Nevertheless, although we show deference to legislatures in their decisions on how to define the elements of an offense, there are “certain limited circumstances” in which “facts not formally identified as elements of the offense charged” must be submitted to the jury and proven beyond a reasonable doubt. McMillan, 477 U.S. at 86, 106 S.Ct. at 2416. Generally speaking, the legislature cannot relieve the government of proving beyond a reasonable doubt an “essential ingredient of the offense.” Jones v. United States, 526 U.S. 227, 241, 119 S.Ct. 1215, 1223, 143 L.Ed.2d 311; see also Harris v. United States, — U.S.-, 122 S.Ct. 2406, 2410, 153 L.Ed.2d 524 (2002) (noting that “constitutional guarantees attach to ... facts” that are the “essential elements” of a given crime); In re Winship, 397 U.S. at 364, 90 S.Ct. at 1073 (stating that there must be “proof beyond a reasonable doubt of every fact necessary to constitute the crime with which [the defendant] is charged”). For example, as we explained in Part H.A., although legislatures have great flexibility in defining certain facts as sentencing factors rather than an offense elements, McMillan, 477 U.S. at 85, 106 S.Ct. at 2415, the legislature cannot label facts as sentencing factors if those facts are used to enhance the defendant’s sentence beyond the prescribed statutory maximum, Apprendi, 530 U.S. at 490, 120 S.Ct. at 2362-63. Additionally, once 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. See McMillan, 477 U.S. at 86-87, 106 S.Ct. at 2416-17; Patterson, 432 U.S. at 215, 97 S.Ct. at 2329. Furthermore, the Supreme Court has suggested that when certain types of facts, though labeled as something other than elements by the legislature, are “traditional elements” of an offense, the constitutional safeguards provided by the Due Process Clause and the Sixth Amendment right to a jury trial still may apply. Jones, 526 U.S. at 241-42, 119 S.Ct. at 1223; see also Harris, 122 S.Ct. at 2414. The Supreme Court has indicated that facts are traditional elements when there is a strong common-law tradition of treating those types of facts as something that must be proven to a jury beyond a reasonable doubt. See Harris, 122 S.Ct. at 2416 (noting that its conclusion that facts used to establish a mandatory minimum sentence need not be submitted to a jury for proof beyond a reasonable doubt “might be questioned if there were extensive historical evidence showing that facts increasing the defendant’s minimum sentence ... have, as a matter of course, been treated as elements”); Apprendi at 476-85, 120 S.Ct. at 2355-60 (discussing the common-law tradition as part of its analysis of whether facts that enhance a defendant’s sentence must be proven to jury beyond a reasonable doubt). 5. Application of These Principles to the Appellants’ Argument With these principles in mind, we analyze whether Congress acted constitutionally in adding 46 U.S.C. app. § 1903(f) to the MDLEA, which provides that the question of whether a vessel is subject to the jurisdiction of the United States should be treated purely as an issue of subject matter jurisdiction for the court to decide. To begin, we note that the present situation is not one in which Congress has labeled certain facts as sentencing facts rather than offense elements; thus, the unique proscription upon legislative power in defining crimes that was set forth in Apprendi, 530 U.S. at 490, 120 S.Ct. at 2362-63, is not applicable here. Neither is this a case in which Congress has shifted the burden of persuasion with respect to an offense element to the defendant, nor is it one in which Congress has otherwise created any presumptions as to offense elements that negate the defendant’s presumption of innocence. Thus, the teachings of McMillan, 477 U.S. at 86-87, 106 S.Ct. at 2416-17, and Patterson, 432 U.S. at 215, 97 S.Ct. at 2329, have no bearing on the present situation. We turn, then, to whether the MDLEA jurisdictional requirement raises factual questions that traditionally would have been treated as elements of an offense under the common law, thereby triggering the constitutional safeguards provided by the Due Process Clause and the Sixth Amendment right to a jury trial. Jones, 526 U.S. at 241-42, 119 S.Ct. at 1223; see also Harris, 122 S.Ct. at 2414. We conclude that the MDLEA jurisdictional requirement does not raise factual questions that traditionally would have been treated as elements of an offense under the common law. As used in the common law, the “elements” of an offense include each part of the actus reus, causation, and the mens rea that the government must establish before an individual can be found guilty of a crime. See Black’s Law Dictionary 520 (6th ed.1990) (defining “Elements of crime” in part as “[a] term used by the common law to refer to each component of the actus reus, causation, and the mens rea that must be proved in order to establish that a given offense has occurred”); see also Morissette v. United States, 342 U.S. 246, 251-52, 72 S.Ct. 240, 244, 96 L.Ed. 288 (1952) (“Crime, as a compound concept, generally constituted only from concurrence of an evil-meaning mind with an evil-doing hand, was congenial to an intense individualism and took deep and early root in American soil.”); People v. Torres, 848 P.2d 911, 914 (Colo.1993) (en banc) (“Generally, in order to subject a person to criminal liability, there must be a concurrence of the actus reus, an unlawful act, and the mens rea, a culpable mental state.”) (emphasis in original); Garnett v. State, 332 Md. 571, 632 A.2d 797, 800 (1993) (“At common law, a crime occurred only upon the concurrence of an individual’s act and his guilty state of mind.”). The requirement under 46 U.S.C. app. § 1903 that a vessel be subject to the jurisdiction of the United States, however, does not go to the actus reus, causation, or the mens rea of the defendant. We reach this conclusion based in part on the reasoning in United States v. Gonzalez, 776 F.2d 931 (11th Cir.1985), where we interpreted the predecessor statute to 46 U.S.C. app. § 1903, the Marijuana on the High Seas Act, 21 U.S.C. § 955a-d. In Gonzalez, we discussed the jurisdictional requirement of § 955a(c), under which the “Coast Guard [was authorized to] seek permission from foreign governments to prosecute foreign nationals found on foreign vessels on the high seas.” 776 F.2d at 935. In discussing this jurisdictional requirement premised on consent from a foreign government, we noted that the requirement was not mandated by either international law or treaty. Id. at 940. Rather, we noted that Congress, under the “protective principle” of international law, may assert extraterritorial jurisdiction over vessels in the high seas that are engaged in conduct that “has a potentially adverse effect and is generally recognized as a crime by nations that have reasonably developed legal systems.” Id. at 939. We further stated that the jurisdictional requirement was inserted into the statute as a diplomatic courtesy to foreign nations and as a matter of international comity in order to avoid “friction with foreign nations.” Id. at 940. This, in turn, led us to the conclusion that it was misleading to view the jurisdictional requirement as a necessary element of the offense, rather than as “a diplomatic requisite illustrating the international partnership that ensures the rule of law on the high seas.” Id.; see also United States v. Devila, 216 F.3d 1009, 1017 (11th Cir.2000) (per curiam), vacated in part on other grounds, 242 F.3d 995 (11th Cir.), cert. denied, — U.S.-, 122 S.Ct. 103, 151 L.Ed.2d 62 (2001) (noting that the jurisdictional requirement that a foreign nation consent to or waive objection to United States enforcement under 46 U.S.C. app. § 1903 was inserted into the statute “to protect the interest of th[e] flag nation and international comity, not the interest of the individuals aboard the vessel”). These statements demonstrate that the statutory jurisdictional requirement contained in 46 U.S.C. app. § 1903 is unique because it is not meant to have any bearing on the individual defendant, but instead is meant to bear only on the diplomatic relations between the United States and foreign governments. Based on the reasoning of Gonzalez, it is clear that the statutory jurisdictional requirement is an ancillary consideration that was enacted as part of the statute in order to promote smooth relations between sovereigns in the domain of international waters. The § 1903 jurisdictional requirement, therefore, does not constitute a traditional element of an offense, given that it has nothing to do with the “concurrence of an evil-meaning mind with an evil-doing hand” as reflected in the common law. Morissette, 342 U.S. at 251, 72 S.Ct. at 244. The § 1903 jurisdictional requirement does not affect the defendant’s blameworthiness or culpability, which is based on the defendant’s participation in drag trafficking activities, not on the smoothness of international relations between countries. See United States v. Klimavicius-Viloria, 144 F.3d 1249, 1257 (9th Cir.1998) (concluding that jurisdictional nexus requirement imposed by Ninth Circuit in MDLEA cases is to be decided by judge because it does not go to the guilt or innocence of defendant); see also United States v. Webster, 162 F.3d 308, 330 (5th Cir.1999) (noting that jurisdictional issues do not aid “in singling out the guilty from the innocent or in deterring future conduct”); United States v. Bryant, 766 F.2d 370, 375 (8th Cir.1985) (noting that jurisdictional issues do not affect the blameworthiness or culpability of the defendant, for “the offense is still every bit as grave in the moral sense” even absent the jurisdictional provision). For these reasons, the § 1903 jurisdictional requirement is unlike the actus reus, causation, and the mens rea components that make up the traditional offense elements as historically understood in this country. The Supreme Court case of Ford v. United States, 273 U.S. 593, 47 S.Ct. 531, 71 L.Ed. 793 (1927), which involved a jurisdictional issue similar to the one in this case, buttresses our position. Ford is like the instant case in that it involved a ship that had been seized at sea for carrying contraband, namely, liquor during the Prohibition era. One issue in the case was whether the ship had been seized within the area designated by a treaty to which the United States and Great Britain were the parties. The Supreme Court held that the question of whether the defendants’ ship had been seized within the area delineated by the treaty was for the judge to decide, since the issue was one of jurisdiction. Id. at 606, 47 S.Ct. at 535. The Court reasoned that the jurisdictional issue “was necessarily preliminary to th[e] trial,” given that “[t]he issue whether the ship was seized within the prescribed limit did not affect the question of the defendants’ guilt or innocence. It only affected the right of the court to hold their persons for trial.” Id.; see also Klimavicius-Viloria, 144 F.3d at 1257 (discussing Ford). Ford supports our determination that statutory jurisdictional requirements like the one in the MDLEA do not fit into the traditional definition of what constitute offense elements. Hence, the § 1903 jurisdictional requirement is not an essential ingredient or an essential element of the MDLEA substantive offense, and, as a result, it does not have to be submitted to the jury for proof beyond a reasonable doubt. We note, furthermore, that we are not swayed by the appellants’ contention that, since the MDLEA jurisdictional issue is a fact-bound determination, Gaudin requires that it be submitted to the jury for proof beyond a reasonable doubt. Contrary to the appellants’ assertions, Gaudin never stated that all factual determinations must go the jury. Rather, Gaudin stands for the proposition that elements of an offense that involve factual determinations, or mixed determinations of law and fact, must go to the jury. 515 U.S. at 511-15, 522-23, 115 S.Ct. at 2314-16, 2320. If the factual determination has no bearing on an element of the offense, the principles laid down in Gaudin do not apply. See id. at 525-26, 115 S.Ct. at 2321 (Rehnquist, J., concurring) (pointing out that, even after Gaudin, many factual determinations still can be made by the judge, as in the context of “[preliminary questions in a trial regarding the admissibility of evidence, the competency of witnesses, the voluntariness of confessions, the legality of searches and seizures, and the propriety of venue”) (internal citations omitted). Hence, although fact-bound determinations may be involved, that does not automatically mean that the 46 U.S.C. app. § 1903 jurisdictional issue has to be decided by the jury. Whether an issue involves factual determinations, in other words, is not talismanic with respect to the question of whether Congress can remove a particular question from the jury’s determination. Consequently, even if questions under the 46 U.S.C. app. § 1903 jurisdictional requirement may have a factual component, -that component does not have to be resolved by the jury, given that, as we have explained, the jurisdictional requirement goes only to the court’s subject matter jurisdiction and does not have to be treated as an element of a MDLEA substantive offense. In sum, we reject the appellants’ argument that the MDLEA, 46 U.S.C. app. § 1903(f), is unconstitutional under Gau-din and other related cases. Although the Due Process Clause and the Sixth Amendment right to a jury trial require that each element of a criminal offense be submitted to the jury for proof beyond a reasonable doubt, Congress made clear through the 1996 amendment to the MDLEA that the jurisdictional requirement is not an element of a § 1903(a) substantive offense, but rather is an issue that goes only to the subject matter jurisdiction of the federal courts. We also have concluded that Congress had the flexibility under the Constitution, at least with respect to the statutory jurisdictional requirement at issue in this case, to decide that the jurisdictional issue should be solely one of subject matter jurisdiction for the court to decide, and not an element of the MDLEA substantive offense. This is because the jurisdictional provision here is not a traditional element, or otherwise an essential ingredient, of a criminal offense. C. The District Court’s Decision as a Matter of Law that the Appellants’ Vessel Constituted a Vessel Subject to the Jurisdiction of the United States under the MDLEA In this subsection, we address whether the district court erred in concluding that, as a matter of law, the statutory requirements for subject matter jurisdiction imposed by 46 U.S.C. app. § 1903 were met in this case. Section 1903(c)(1)(A) states that “a vessel without nationality” is included within the definition of a vessel subject to the jurisdiction of the United States. 46 U.S.C. app. § 1903(c)(1)(A). A vessel is without nationality if, among other things, “the master or person in charge makes a c
