TORRUELLA, Circuit Judge,
opinion of the court except as to Part 11(A); dissenting in Part 11(A).1
Appellant Luis Segundo Vilches-Navar-rete (“Vilches”) was convicted of: (1) pos[5]*5session with intent to distribute five kilograms or more of cocaine, in violation of the Maritime Drug Law Enforcement Act (“MDLEA”), 46 U.S.C. § 70503;2 and (2) conspiracy to possess with intent to distribute more than five kilograms of cocaine, in violation of 46 U.S.C. § 70506(b) on multiple grounds. Vilches was apprehended for trafficking drugs in international waters by the United States Coast Guard (“USCG”). On appeal, he makes numerous arguments. He argues that the MDLEA is unconstitutional and that the district court lacked jurisdiction. He also challenges the district court’s refusal to suppress evidence, to grant a motion to dismiss, as well as the sufficiency of the evidence upon which he was convicted. He claims that his sentence was unreasonable and that the numerous errors in the case prejudiced his right to a fair trial. After careful consideration, we affirm his conviction and the sentence imposed by the district court.
I. Background3
On January 31, 2005, during a routine drug patrol in the eastern Caribbean Sea, USCG Lieutenant Adam Nolen Berkley, whose boarding team was deployed on the British Royal Fleet’s Auxiliary Ship, the Wave Ruler, received information from a maritime patrol aircraft about a vessel of interest in international waters. A cargo vessel heading north had smaller vessels coming alongside it, which raised the suspicion of the USCG. The USCG continued to monitor the vessel.
The next morning, using the British ship’s helicopter, the USCG identified the vessel, the Babouth, which was flying the Honduran flag. As the USCG approached and performed a visual inspection, it made radio contact with the crew. Berkley was suspicious of the answers to some of his questions. He noted that the vessel had rub marks along the side; furthermore, it was rocking slowly back and forth. Berk-ley knew this to be a sign of a very heavy load. Additionally, the Babouth had an unusually large number of antennae, indicative of a great deal of electronic equipment on board for a vessel of this nature. Based on these factors, Berkley believed he had reasonable suspicion to approach the vessel. As he approached the Ba-bouth, he raised the USCG flag, converting the Wave Ruler into a law enforcement vessel. Berkley also faxed a report to the officer on duty at the USCG, Southern District, and followed up with a phone call requesting that the USCG contact the Honduran government for permission to board and search the Babouth. Thereafter, the Honduran government granted permission, first verbally, and later followed by an official, written communication.
The Babouth was fifty nautical miles west of Grenada, traveling in a north, northwesterly direction towards Puerto Rico and St. Croix when the USCG intercepted it. This area is a known drug trafficking area. Petty Officer Michael Christopher Acevedo, who was familiar with the area and its history of drug trafficking, boarded the Babouth with the permission of both the Government of Honduras and Vilches, its captain. Acevedo remained on the vessel for the duration [6]*6of the search and was the officer in charge.
Upon inspection, Berkley noticed that the Babouth had too much free board. He also noticed that the vessel was rusty and looked to be in poor repair. The Babouth also had drums commonly used by drug traffickers, including a 500-gallon fuel container that smelled strongly of, and contained what looked like, gasoline. Vilches told the officers that it was a septic tank for the toilets. The officers inspected the tank, and observed that it did not lead to a toilet but to the back of the boat and over the side.
Acevedo asked Vilches for the registration documents and manifest of the Ba-bouth. Vilches turned over a briefcase with documents for the ship, and provided Acevedo with an affidavit prepared in Trinidad stating that the registration had been lost. Acevedo, however, found the vessel’s registration in Vilches’s briefcase; it had expired on December 14, 2004.
After a safety inspection and a search for weapons, the officers looked for indicators that the vessel was being utilized for smuggling contraband. They found freshly painted areas, spilled concrete, a bag of concrete mix, and fresh welds, all of which are indicators of hidden compartments. The sweep team also found other items which raised their suspicion about the contents of the vessel and the real purpose for which it was being used. Berkley and Acevedo found communication devices at the ship’s bridge, similar to those Acevedo had seen in other drug seizure cases at sea.
The Babouth contained navigational charts without plot marks and a global positioning system (“GPS”) that was not being used. Vilches claimed that he did not use them because he was an experienced mariner. Despite this assertion, while on board the Babouth, Acevedo noted that Vilches did utilize the charts and the GPS.
On the third day, another inspection team came to complete a space-accountability inspection. The concrete blocks on board, which Vilches had described as extremely sturdy, fell apart as the officers tried to move them. The inspection team found that the bill of lading for the ship’s cargo conflicted with the ship’s invoice. Vilches could not provide a satisfactory explanation for the discrepancy even though the ship’s forms carried his seal and signature. In addition, Acevedo asked Vilches why they had been traveling so slowly since a cargo vessel would want to deliver its cargo quickly. Vilches blamed the slowness of the vessel on engine problems. He claimed that there was a hydraulic leak in the jacket of the water pump. Acevedo, a qualified mechanic, inspected the engine and found no hydraulic lines used for the jacket of the water pump.
By February 5, 2005, the Babouth was in U.S. waters, and a task force boarded the vessel and continued the search. Vilches consented to the search. For safety reasons, the vessel was taken to the USCG’s station in San Juan, Puerto Rico. On February 7, 2005, while still searching the Babouth at the port, one of the Bar bouth’s crew members, Luis Fernando Piedrahita-Calle (“Piedrahita”), communicated by note that he wanted to speak to the DEA.
Piedrahita met with the officers and told them where drugs were hidden and how the plan to smuggle the drugs was executed. Agents reboarded the Babouth and went to the area identified by Piedrahita. Vilches’s attitude, which had been cooperative, changed once the agents returned after receiving the note from Piedrahita. As the agents searched the back part of [7]*7the vessel, Vilches became assertive and questioned the agents about their search. Following Piedrahita’s instructions, the agents found a well-hidden hatch under the linoleum floor. Under about six to ten inches of sand, sawdust, and ammonia, the officers found a bolted manhole cover. Inside the manhole, they found several white burlap sacks which tested positive for cocaine. The agents recovered thirty-five bales of cocaine, weighing approximately 950 kilograms.4 Earlier, a canine had detected a narcotic odor in the area later identified by Piedrahita.
A. Indictment and Trial
After the USCG found the drugs on the boat, Vilches was arrested and charged with possession with the intent to distribute under the § 70503 of the MDLEA and with conspiracy to possess with intent to distribute under § 70506(b). On July 26, 2005, Vilches joined a co-defendant’s motions to suppress the evidence and dismiss the indictment. The district court denied the motions.
Mardonio Chávez-Senti (“Chávez”), one of Vilches’s co-defendants, pled guilty and testified at trial on behalf of the Government. He provided details of the conspiracy and of the day that the Babouth was intercepted by the USCG.
According to his testimony, Chávez, a naval mechanical engineer, met with Pedro Valleadares, Antonio Ruiz, Aldo Lara, and José Sandoval, and agreed to participate in the drug trafficking venture for $30,000. He testified that Vilches joined them in Haiti to help prepare for the drug run; the Babouth left Haiti for Tortola to pick up drugs.
Chávez recounted that at around midnight on January 31, 2005, Vilches called him and told him that they were at the prearranged point for the drug pick-up, but the boat bringing the drugs had not arrived. About an hour later, a motorboat, which Vilches was in contact with by radio, came up to the hull of the Babouth and people on the boat passed the bales of drugs up to the crew. The entire crew, with the exception of Vilches, who was piloting the vessel, participated in loading the drugs. A total of thirty-five bales were loaded. The motorboat then left. Chávez testified that the crew hid the bales in an empty water tank under the floor of the Babouth. The crew then informed Vilches that the job was complete. Vilches continued sailing, but was soon thereafter intercepted by the USCG.
Vilches was the only defense witness. He admitted being the captain of the Ba-bouth, but denied any knowledge of the drugs on board. Vilches denied making any satellite phone calls and denied any knowledge of a boat coming alongside the Babouth. He claimed that there was no discrepancy as to the number of pallets, despite the difference in quantity on the bill of lading and invoices. Though he admitted to knowing them, Vilches denied knowing how to contact either Sandoval or Lamberti. His address book, however, had contact information for both men; their names were highlighted in yellow. Vilches was also confronted with Ms falsified navigation license, for which he gave no satisfactory explanation.
Vilches moved for a Rule 29 dismissal under the Federal Rules of Criminal Procedure at the conclusion of the Government’s case and again at the conclusion of his own case. The district court denied [8]*8both motions. The jury found Vilches guilty on both counts. He did not move to set aside the verdict.
B. Sentencing
Vilches’s Pre-Sentencing Report (“PSR”) grouped the two counts and calculated a base offense level of thirty-eight pursuant to U.S.S.G. § 2Dl.l(c)(l). Taking into account Vilches’s role as captain of the Babouth, the PSR added two levels pursuant to U.S.S.G. § 2Dl.l(b)(2), for a total offense level of forty. Although Vilches had a prior record, the PSR calculated zero criminal history points, resulting in a criminal history category of I, because his convictions fell outside of the time limit for inclusion. See U.S.S.G. § 4A1.2(e)(l). The PSR calculated an advisory guideline range of 292 to 365 months. The PSR included the statutory minimum term of ten years and a maximum of life. It noted that Vilches is a Chilean citizen with no legal status in the United States and that he would face removal proceedings upon completion of his sentence. No objections were filed to the PSR.
At the sentencing hearing held on May 19, 2006, Vilches’s counsel requested that the court take into account the 18 U.S.C. § 3558(a) sentencing factors, and argued that a sentence of 292 months, the bottom of the Guidelines range, would be adequate considering Vilches’s age. Counsel argued that a higher sentence for Vilches’s crime, which did not involve violence, “could be interpreted as punishment because he exercised his right to jury trial.” When Vilches addressed the court, he insisted he was innocent. The Government called attention to Vilches’s history and characteristics under § 3553(a) and requested a sentence at the top of the guideline range, 365 months.
Consistent with the PSR, the district court calculated Vilches’s sentence between 292 and 365 months. Taking into account the advisory guidelines and the § 3353(a) factors, the district court sentenced Vilches to 365 months for each count, to be served concurrently. The court noted that Vilches’s prior drug-related convictions were indicative of his recidivism. The court found that “a sentence at the top of the guideline range is the appropriate and the reasonable sentence.” The court imposed an additional sentence of concurrent five-year terms of supervised release and a mandatory special monetary assessment, and upon motion declined to reconsider the sentence.
Vilches appeals and challenges the constitutionality of the MDLEA, the district court’s jurisdiction, the district court’s refusal to suppress evidence, the sufficiency of the evidence, and the reasonableness of his sentence, and argues for reversal based on a totality of errors. We address these challenges in turn.
II. Discussion
A. Constitutionality of the MDLEA
Once again, we are asked to decide the constitutionality of the jurisdictional element of the MDLEA. See United States v. Gil-Carmona, 497 F.3d 52, 54 (1st Cir.2007). The MDLEA makes it a crime for any person on board “a vessel subject to the jurisdiction of the United States,” 46 U.S.C. § 70503(a)(1), to “knowingly or intentionally manufacture or distribute, or possess with intent to manufacture or distribute, a controlled substance,” 46 U.S.C. § 70503(a). A “vessel subject to the jurisdiction of the United States” includes a “vessel registered in a foreign nation where the flag nation has consented or waived objection to the enforcement of United States law by the United States.” [9]*9Id. at § 70502(c)(1)(C).5
Although the concurrence feels compelled to resolve this issue, the doctrine of constitutional avoidance requires us to refrain from ruling on the constitutionality of this statute because the posture of this case does not require us to pass upon this issue.6 I believe we should not reach the [10]*10merits of the constitutionality of this law because Vilches has not demonstrated that the district court committed plain error. I thus disagree with the reaching of this issue by the concurring opinion by Judges Lynch and Howard and express no opinion at this time on this matter.
The standard of review for a defendant’s claim that his constitutional rights were violated by congressional removal of an [11]*11element' of a charged offense from the jury’s consideration is ordinarily harmless error. See Neder v. United States, 527 U.S. 1, 15, 119 S.Ct. 1827, 144 L.Ed.2d 35 (1999). Here, however, we apply plain error because Vilches did not object to the constitutionality of the statute in the district court. See United States v. Brown, 510 F.3d 57, 72 (1st Cir.2007). Under the plain error standard, Vilches must prove “(1) an error, (2) that is plain, and (3) that affects substantial rights,” United States v. Connolly, 341 F.3d 16, 31 (1st Cir.2003) (quoting United States v. Downs-Moses, 329 F.3d 253, 263 (1st Cir.2003)) (internal quotation marks omitted), and that the error “seriously impaired the fairness, integrity, or public reputation of judicial proceedings.” Id. (quoting United States v. Matos, 328 F.3d 34, 43 (1st Cir.2003) (internal quotation marks omitted)).
Like in Gil-Carmona, the district court record clearly shows that the jury was presented with evidence that the Babouth was subject to the jurisdiction of the United States. At trial, Berkley testified that while the Babouth was apprehended in international waters, he requested and was granted both verbal and written permission, through the USCG, Seventh District, by the Government of Honduras to board and search the Babouth pursuant to the Honduran-U.S. Counter Drugs Operations bilateral agreement. See Certification for the Maritime Drug Law Enforcement Act Case Involving the Vessel Babouth (Honduras). The MDLEA allows for U.S. officials to conduct searches on foreign flagged vessels with permission of the foreign state. See 46 U.S.C. § 70502(c)(2)(A), (B).7 The Government presented the district court with documentation containing the Seal of the United States Department of State which stated that the Government of Honduras had granted the United States permission to enforce U.S. law against the Babouth, its cargo, and the people on board. See United States v. Guerrero, 114 F.3d 332, 340 n. 9 (1st Cir.1997) (“We acknowledge that the 1996 amendments to § 1903 provide that the Secretary of State’s certification ‘conclusively’ proves a foreign nation’s consent.”).
Vilches did not object to the Government’s arguments regarding jurisdiction at trial. His failure to object alone suggests that the asserted error was not plain. Cf. Gil-Carmona, 497 F.3d at 55. In fact, at trial, Vilches had the opportunity to question the Government’s presentation with regard to jurisdiction, but he chose merely to question how long it took between the time Berkley saw the Honduran flag and when he received permission to board the vessel. “[T]he record establishes beyond a reasonable doubt that jurisdiction over the vessel existed under [§ 70504].” Id. Even if the jury had been expressly presented with the question of jurisdiction, any reasonable jury would have found Vilches guilty. It cannot be said that any error in failing to submit the question of jurisdiction to the jury “seriously impaired the fairness, integrity, or public reputation of judicial proceedings.” United States v. Duarte, 246 F.3d 56, 60 (1st Cir.2001); cf. Gil-Carmona, 497 F.3d at 55; Neder, 527 U.S. at 19, 119 S.Ct. 1827. There was no plain error.
B. Jury Instruction on Jurisdiction
Vilches argues that the district court’s jury instruction was erroneous because it “improperly invaded the province of the [12]*12jury determinations and violated the Ap-prendi principle.”8 Normally, this issue would be subject to de novo review. See United States v. Bravo, 489 F.3d 1, 7 (1st Cir.2007). Vilches, however, made no objection below, and we review a claim of error not properly preserved below for plain error. See United States v. Cotton, 535 U.S. 625, 627-29, 122 S.Ct. 1781, 152 L.Ed.2d 860 (2002) (holding that a defendant’s failure to object to Apprendi error at trial requires plain error review); United States v. Portes, 505 F.3d 21, 25 (1st Cir.2007).
The MDLEA provides that “[jjurisdic-tional issues arising under this chapter are preliminary questions of law to be determined solely by the trial judge.” 46 U.S.C. § 70504(a). The district court correctly instructed the jury that the “[j]uris-diction of the United States with respect to vessels subject to this chapter is not an element of any offense.” Id. In its jury instruction, the district court plainly said: “I’m instructing you that as a matter of law the motor vessel Babouth was subject to the jurisdiction of the United States.” This was a correct statement of the law. See Guerrero, 114 F.3d at 340 n. 9 (“United States jurisdiction over vessels is no longer an element of an offense, but rather, a preliminary question of law for the trial judge”); United States v. Tinoco, 304 F.3d 1088, 1106 (11th Cir.2002) (“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.”). At the conclusion of the jury instructions the district court asked whether there were any objections to the instruction. Vilches’s counsel said no. There was no plain error.
C. Motions to Suppress and Dismiss
“We apply a mixed standard of review to the district court’s denial of a suppression motion, reviewing the court’s findings of fact for clear error and the application of the law to those facts de novo.” Bravo, 489 F.3d at 8 (citing Tinoco, 304 F.3d at 1116).
Vilches argues that his Fourth Amendment rights were violated because the USCG lacked reasonable suspicion to search the Babouth. Vilches further argues that Rule 5(a) of the Federal Rules of Criminal Procedure were violated because it took five days for the USCG to get the Babouth to port in San Juan.9
Vilches further contends that he was erroneously denied a suppression hearing and that this error unconstitutionally precluded him from properly developing and supporting his motion to suppress. Vilch-es also argues that the district court erred in holding that he lacked standing to challenge the constitutionality of the stop and seizure. Vilches further argues that the warrantless detention of his person for several days constituted a de facto arrest and that the scope of the detention was unreasonable. We are unconvinced by any of Vilehes’s arguments and take them in turn.
[13]*131. Alleged Fourth Amendment Violation
As we have said before, “the Fourth Amendment does not apply to activities of the United States against aliens in international waters.” Bravo, 489 F.3d at 8; see also United States v. Verdugo-Urquídez, 494 U.S. 259, 267, 110 S.Ct. 1056, 108 L.Ed.2d 222 (1990) (“There is ... no indication that the Fourth Amendment was understood by contemporaries of the Framers to apply to activities of the United States directed against aliens in foreign territory or in international waters.”). Vilches is Chilean, and he was not residing in the United States. He was in international waters when he was approached by the USCG. The district court properly dismissed Vilches’s Fourth Amendment claim pertaining to the USCG’s actions in international waters.
The district court also properly extended the same reasoning when it dismissed Vilches’s Fourth Amendment claim based on the search of the Babouth at the port in San Juan. In Verdugo-Urquidez, the Supreme Court held that the defendant did not have constitutional rights based on his presence in the United States because constitutional protections only attach to aliens who “come within the territory of the United States and developed substantial connections with this country.” Verdugo-Urquidez, 494 U.S. at 271, 110 S.Ct. 1056. Vilches can claim no such “substantial connections.” Like Verdugo-Urquídez, who was imprisoned in California and had “no previous significant voluntary connection to the United States,” id., Vilches was brought to the United States for the sole purposes of conducting a safe search of the vessel he captained. “[T]his sort of presence — lawful but involuntary— is not of the sort to indicate any substantial connection with our country.” Id. In this case, we are unable to say that Vilch-es’s presence at the port in San Juan was completely involuntary because he consented to the search and the USCG’s docking the Babouth in San Juan.
But even if Verdugo-Urquidez does not apply, Vilches lacks standing to challenge the search. It is “well settled that a defendant who fails to demonstrate a legitimate expectation of privacy in the area searched or the item seized will not have ‘standing’ to claim that an illegal search or seizure occurred.” United States v. Mancini, 8 F.3d 104, 107 (1st Cir.1993) (citing Rakas v. Illinois, 439 U.S. 128, 138-48, 99 S.Ct. 421, 58 L.Ed.2d 387 (1978)). In order to make such a showing, Vilches must show that he had both a subjective expectation of privacy and that society accepts that expectation as objectively reasonable. California v. Greenwood, 486 U.S. 35, 39, 108 S.Ct. 1625, 100 L.Ed.2d 30 (1988); cf. United States v. Scott, 975 F.2d 927, 928 (1st Cir.1992). The burden of proving a reasonable expectation of privacy lies with Vilches. United States v. Sánchez, 943 F.2d 110, 113 (1st Cir.1991). Vilches must demonstrate an expectation of privacy in both the item seized and the place searched. United States v. Salvucci, 448 U.S. 83, 93, 100 S.Ct. 2547, 65 L.Ed.2d 619 (1980). Vilches cannot make that showing here.
“[T]he circumstances and exigencies of the maritime setting afford people on a vessel a lesser expectation of privacy than in their homes, obviating the usual fourth amendment requirements of a warrant.” United States v. Green, 671 F.2d 46, 53 (1st Cir.1982). As the Government argues, Vilches had no reasonable expectation of privacy in the secret compartment in which the drugs were found. Cf. United States v. Cardona-Sandoval, 6 F.3d 15, 22 (1st Cir.1993) (distinguishing “substantial vessels such as cargo ships and freighters” from “a small pleasure craft used for fish[14]*14ing” where captain had reasonable expectation of privacy).
Even if Vilches had a subjective expectation of privacy, it was not an objectively reasonable expectation. The district court rightly noted that “society would not recognize a justifiable expectation of privacy in a hidden compartment created for the express purpose of hiding illicit contraband. To hold otherwise would grant smugglers standing under the Fourth Amendment solely because they were careful in hiding their illicit merchandise.” Vilches-Navarrete, 413 F.Supp.2d at 73-74; see also United States v. Sarda-Villa, 760 F.2d 1232, 1235 (11th Cir.1985) (“[W]e are not willing to say that society is prepared to recognize a justifiable expectation of privacy solely on the basis of appellants’ efforts to secret the contraband. Drug smugglers cannot assert standing solely on the basis that they hid the drugs well and hoped no one would find them.”). As the Supreme Court said in Kyllo v. United States, 533 U.S. 27, 121 S.Ct. 2038, 150 L.Ed.2d 94 (2001), “a Fourth Amendment search does not occur ... unless ‘the individual manifested a subjective expectation of privacy in the object of the challenged search,’ and ‘society [is] willing to recognize that expectation as reasonable.’ ” Id. at 33, 121 S.Ct. 2038 (quoting California v. Ciraolo, 476 U.S. 207, 211, 106 S.Ct. 1809, 90 L.Ed.2d 210 (1986)).
The search was valid in any event because the USCG’s “authority under 14 U.S.C. § 89(a) to stop and board a vessel on the high seas is quite broad.”10 Cardonar-Sandoval, 6 F.3d at 23 (internal footnotes omitted). In the instant case, the USCG had consent from Honduras, the vessel’s flag country, to board the Babouth and to take it to a U.S. port to complete the search. The USCG also possessed the requisite “reasonable and articulable grounds for suspecting that the vessel or those on board [we]re engaging in criminal activity.” Green, 671 F.2d at 53.
As the USCG’s monitored the Babouth, it observed smaller vessels coming into contact with it the night before the USCG boarded the vessel. The following day the USCG detected rub marks along the port side of the Babouth but not its starboard, confirming their belief in suspicious activity. On board, the USCG’s found even more evidence of suspicious activity. For example, there was a discrepancy between the number of pallets that the Babouth was carrying and those that were slated for delivery, and the GPS and navigational charts had been erased.
Each step of the USCG’s search was based on “a corresponding level of suspicion supported by specific facts.” Cardona-Sandoval, 6 F.3d at 23. In United States v. Berryman, 717 F.2d 651 (1st Cir.1983), we said that “although some encounters [with the Government] do not [15]*15implicate fourth amendment concerns at all, more intrusive encounters short of arrests must be justified by reasonable suspicion proportional to the degree of the intrusion. That suspicion cannot be inchoate, but must be based on ‘specific and articulable facts ... together with rational inferences from those facts’ in order to establish a basis for review of the police actions.” Id. at 653 (internal citations omitted). The USCG had the requisite reasonable suspicion.
Furthermore, as the district court found, Vilches “gave his permission to the boarding team ‘to access any space on the vessel.’ ” Vilches-Navarrete, 413 F.Supp.2d at 72. Both at sea and at the port in San Juan, Vilches consented to the USCG’s boarding of the Babouth and the search of the vessel. At no point did he object to the boarding of the vessel, the search of the vessel, or the taking of the vessel to San Juan. “It is ... well settled that one of the specifically established exceptions to the [Fourth Amendment] requirements of both a warrant and probable cause is a search that is conducted pursuant to consent.” Schneckloth v. Bustamonte, 412 U.S. 218, 219, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973); see also United States v. Meléndez, 301 F.3d 27, 32 (1st Cir.2002). Additionally, as mentioned above, Honduras, under whose flag the Babouth sailed, consented to the search of the boat both at sea and in U.S. territory.
Accordingly, the denial of the motion to suppress is affirmed.
2. Motion to Suppress Hearing
“The test for granting an evidentiary hearing in a criminal case [is] substantive: did the defendant make a sufficient threshold showing that material facts were in doubt or dispute?” United States v. Panitz, 907 F.2d 1267, 1273 (1st Cir.1990). Vilches made no such showing. A hearing was not necessary to address the suppression issues because in support of his motion, Vilches merely presented the same statements by the USCG as the Government had. Vilches did not dispute the Government’s version of events and instead relied upon then. This makes an evidentiary hearing unnecessary since there were no material facts that were in dispute. See id. at 1273-74; United States v. McGill, 11 F.3d 223, 225 (1st Cir.1993) (“[E]videntiary hearings on motions are the exception, not the rule.”).
3. Vilches’s Arrest
Vilches’s challenge to his arrest is without merit. There was no unreasonable delay between the arrest and Vilches’s initial appearance before a magistrate judge. Vilches was arrested the same day that the USCG discovered the drugs on the Babouth, February 7, 2005. He was taken before a magistrate judge the following day. Furthermore, the short interval between when the USCG first boarded and inspected the Babouth and the travel time before the Babouth arrived in San Juan did not result in a custodial detention. See United States v. Baker, 641 F.2d 1311, 1319 (9th Cir.1981) (“routine Coast Guard boarding of vessels does not create a custodial situation”); cf. United States v. Elkins, 774 F.2d 530, 535 n. 3 (1st Cir.1985) (“It is well recognized that a routine inspection and boarding of an American flagship vessel on the high seas does not give rise to a custodial detention.”). The one day between the time Vilches was arrested and when he was brought before the magistrate judge was reasonable, and the district court properly denied his motion to dismiss.
D. Sufficiency of the Evidence
We review a sufficiency of the evidence claim de novo. See United States [16]*16v. Carucci, 364 F.3d 339, 343 (1st Cir.2004). We will affirm a conviction if, “after assaying all the evidence in the light most amiable to the government, and taking all reasonable inferences in its favor, a rational factfinder could find, beyond a reasonable doubt, that the prosecution successfully proved the essential elements of the crime.” United States v. O’Brien, 14 F.3d 703, 706 (1st Cir.1994). “All ‘reasonable evidentiary inferences’ are to be drawn ‘in harmony with the verdict,’ and ‘all issues of credibility’ are to be resolved ‘in the light most favorable to the government.’ ” United States v. Washington, 434 F.3d 7, 15 (1st Cir.2006) (quoting United States v. Casas, 356 F.3d 104, 126 (1st Cir.2004)).
Vilches argues that no rational trier of fact could have found all of the essential elements of the crimes of possession with intent to distribute cocaine and conspiracy to possess with intent to distribute. He claims that the Government offered “thin isolated points of purported circumstantial evidence,” which under scrutiny are easily explained away. A review of the evidence presented at trial indicates otherwise.
1. Conspiracy
Vilches notes that a conviction for conspiracy requires proof beyond a reasonable doubt of three elements: (1) the existence of an agreement to commit an unlawful act; (2) knowledge and intent to join the agreement; and (3) knowing participation in the conspiracy. United States v. Sepúlveda, 15 F.3d 1161, 1173 (1st Cir.1993). He argues that the Government’s evidence at trial was insufficient to establish any of the three elements. We disagree.
At trial, the Government established beyond a reasonable doubt “the existence of a conspiracy, [Vilches’s] knowledge of the conspiracy, and [Vilches’s] voluntary participation in the conspiracy.” United States v. Gómez-Pabón, 911 F.2d 847, 852 (1st Cir.1990). As we made clear above, the Government proved beyond a reasonable doubt that the Babouth was “subject to the jurisdiction of the United States.” 46 U.S.C. § 70503(a)(1). There is no question or dispute that the USCG found cocaine, undoubtedly a controlled substance, on the Babouth. The Government also proved at trial that Vilches “knowingly or intentionally possessed the controlled substance with the intent to distribute it.” Guerrero, 114 F.3d at 339.
Chávez specifically testified to the details of the conspiracy. See United States v. Cardales, 168 F.3d 548, 554-55 (1st Cir.1999). Chávez testified to Vilches’s involvement in the conspiracy. Specifically, once the Babouth departed Haiti, Vilches was in constant contact with the owner of the drugs, Félix Lamberti. While sailing, Vilches informed Chávez when they reached the predetermined meeting place for receiving the drugs. Vilches is the one who received the call from the motorboat that was carrying the drugs giving its location. Vilches ordered that the Babouth reduce its speed so the drugs could be loaded onto the boat. After the crew loaded the cocaine and hid it under a hatch, they informed Vilches that the drugs were safely on board. Vilches then ordered them to resume their normal speed. The Government met its burden.
2. Possession
With respect to the possession charge, Vilches again argues that there was insufficient evidence that he knowingly possessed the narcotics found on the Babouth. He maintains that the Government failed to meet its burden of proving that he had both knowledge of and access to the narcotics. See United States v. Patterson, 472 F.3d 767, 779 (10th Cir.2006). The facts— [17]*17recounted above — belie Ms assertions of innocence.
Viewed in the light most favorable to the verdict, the evidence is sufficient to sustain the jury’s verdict because it is clear that a reasonable factfinder could find that the Government proved the essential elements of crimes with which Vilches was accused.
3. Circumstantial Evidence
Vilches claims that the Government’s circumstantial evidence does not withstand scrutiny and should be discounted. Contrary to Vilches’s claims, the Government introduced sufficient circumstantial evidence at trial to support his conviction. “In circumstantial cases ..., the evidence is sufficient to convict if it adequately supports ‘the requisite two-step inference’: (1) that the vessel was engaged in obviously illegal activity, and (2) that each Appellant was ready to assist in the criminal enterprise.” Bravo, 489 F.3d at 9 (quoting United States v. Jiménez-Pérez, 869 F.2d 9, 11 (1st Cir.1989)); Guerrero, 114 F.3d at 342 (“proof of sufficient participation in the crime, as well as knowledge of it, is required to convict: the defendant’s ‘mere presence’ at the scene of the criminal activity is not enough”). Vilches’s challenge to the sufficiency of the evidence supporting his convictions attacks only the weight of the evidence; that is insufficient here. He fails to demonstrate that the circumstantial evidence the Government offered is somehow inadequate to meet the test we laid out in Bravo. There was substantial evidence establishing each element of the possession and conspiracy convictions. His arguments are unavailing.
The reason the Babouth came to the attention of the USCG is that they detected vessels coming alongside it under the cover of darkness. The Government presented evidence that the USCG found this suspicious because a vessel of the size of the Babouth would be unlikely to stop in the dark, in the middle of the ocean, for any legitimate reason to take small boats alongside it. The Government also presented evidence that the vessel had unusually excessive electronic equipment, which was inconsistent with its condition; this was consistent with other drug trafficking ventures. Moreover, the USCG intercepted the Babouth in an area well-known for drug trafficking.
There was also evidence that on board the Babouth the officers found indicators of illicit activity and supplies that were consistent with the possibility of empty space behind a false wall. The USCG found fifty-gallon drums, typical of those which could be used by vessels to refuel smaller vessels transporting contraband. A large 500-gallon container, which Vilch-es claimed to be a septic tank, was also found by the USCG. Upon inspection, the USCG found evidence indicating that it contained gasoline and was not used as a septic tank. Additionally, the Babouth’s GPS and navigational charts did not display the ship’s prior course. Despite Vilches’s explanation that he was a seasoned mariner and did not need to use the GPS and charts, the officers witnessed Vilches use them later.
The Babouth’s registration, which Vilch-es claimed he lost, was later discovered in his briefcase by agents during the search. Furthermore, Vilches’s navigational license was fraudulent. The Government also introduced evidence that Vilches was hired by Sandoval, who was present at the meeting in which Chávez was hired for the drug smuggling venture. Vilches testified that as the captain, he was the one to give the orders; nothing could occur on the boat without his orders. Vilches attempted to explain away the suspicions at trial; the jury chose not to believe him. The circumstantial evidence overwhelmingly [18]*18weighs against Vilches. The evidence presented at trial is more than sufficient to sustain the jury’s verdict.
E. Sentence
We “review challenges to sentencing process — ie., errors of law — de novo.” United States v. Rivera, 448 F.3d 82, 84 (1st Cir.2006) (citing United States v. Robinson, 433 F.3d 31, 35 (1st Cir. 2005)). “Reasonableness challenges — ie., challenges to errors of judgment — are reviewed with ‘some deference ... [assuming a plausible explanation and a defensible overall result.’ ” Id. (quoting United States v. Jiménez-Beltre, 440 F.3d 514, 519 (1st Cir.2006)); see also Gall v. United States, — U.S. -, 128 S.Ct. 586, 602, 169 L.Ed.2d 445 (2007) (“On abuse-of-discretion review, the Court of Appeals should have given due deference to the District Court’s reasoned and reasonable decision that the § 3553(a) factors, on the whole, justified the sentence.”).
Vilches argues that the 365-month sentence imposed on him was a “de facto life sentence.” He argues that the sentence was unreasonable under United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), because it was not predicated on the factors listed in § 3553(a). The question for this court is whether the district court’s conclusion is supported by “a reasoned explanation [and] a plausible outcome.” Jiménez-Beltre, 440 F.3d at 519; see also United States v. Zapete-García, 447 F.3d 57, 60-61 (1st Cir.2006).
The district court imposed a 365-month sentence after noting that the Guidelines are advisory and after considering the sentencing factors listed in § 3553(a). The district court noted Vilches’s conduct, including his knowledge of the drug smuggling operation despite his assertion of ignorance. The district court also discussed his prior criminal record, including his 1981 conviction for possession with intent to distribute, and his 1983 conviction, where he received 120 months for possession of marijuana. The district court did not count Vilches’s previous convictions towards his criminal history because of their dates but found them to be indicative of his recidivism. See 18 U.S.C. § 3553(a)(2)(B) (giving judges latitude to imposes sentences that “afford adequate deterrence to criminal conduct”). Finally, the district court considered the fact that Vilches had used a different name in the past. Given the district court’s consideration of the § 3553(a) factors and its reasoned articulation for the sentence, Vilch-es’s 365-month sentence is reasonable. The district court’s reasoning was persuasive and explicit, and the result was proper. The district court’s sentence is affirmed.
F. Totality of the Errors
Vilches argues that under the “cumulative error doctrine,” “[[Individual errors, insufficient in themselves to necessitate a new trial, may in the aggregate have a more debilitating effect.” Sepúlveda, 15 F.3d at 1195-96. Vilches asserts that in this case, the numerous errors prejudiced his rights to a fair trial and violated due process under the Fifth and Sixth Amendments. We find these arguments unconvincing. For the reasons elaborated above, we find that even if there were errors — a question we need not answer — they were harmless. Vilches’s claim necessarily fails. See United States v. Flemmi 402 F.3d 79, 95 n. 23 (1st Cir.2005) (“[BJecause we have found that none of [the defendant’s] individual complaints resulted in substantial prejudice and that most are completely without merit, we reject the final contention that his conviction was tainted by cumulative error.” (quoting [19]*19United States v. DeMasi, 40 F.3d 1306, 1322 (1st Cir.1994))) (internal quotation marks omitted).
III. Conclusion
For the reasons explained above, we affirm Vilches’s conviction and sentence.
Affirmed.
