Eustaquio Yesquen Aguirre1 was one of eight individuals picked up by the United *797States Coast Guard after the boat he was on was found to contain some 2,647 kilograms of cocaine. Yesquen pleaded guilty to possessing with the intent to distribute, and conspiring to possess with the intent to distribute, five or more kilograms of cocaine while on board a vessel subject to the jurisdiction of the United States, all in violation of 46 U.S.C.App. § 1903(a), (g), and 0), and 21 U.S.C. § 960(b)(1)(B)(ii). He now appeals his 135-month sentence.
I.
Yesquen first argues that the district court erred in concluding that his role in the offense was not sufficiently minor to entitle him to a sentence reduction under United States Sentencing Guidelines Manual § 3B1.1 (Nov.2004). Such a conclusion is a factual finding we will reverse only for clear error. United States v. Ryan, 289 F.3d 1339, 1348 (11th Cir.2002).
The gist of Yesquen’s argument on this point is that he was a mere sailor on the drug boat with no decision-making role or equity interest in its cargo. As such, Yesquen says, he was just a pawn in the overall scheme to distribute the drugs. Yesquen also complains that the denial of a minor role reduction is at odds with the Middle District of Florida’s treatment of similar defendants in other drug courier cases and contravenes the Southern District of Florida’s decision in United States v. Dorvil, 784 F.Supp. 849 (S.D.Fla.1991).2
U.S.S.G. § 3B1.2(b) entitles a defendant to a two-point decrease in his offense level if the district court finds that the defendant was a “minor participant” in the criminal activity. U.S.S.G. § 3B1.2(b). A defendant is a “minor participant” if he is
“less culpable than most other participants,” but has a role that “could not be described as minimal.” U.S.S.G. § 3B1.2 cmt. n. 5. To gauge a defendant’s eligibility for this minor-role reduction, the district court first determines “whether a defendant’s particular role was minor in relation to the relevant conduct attributed to him in calculating his base offense level.” Ryan, 289 F.3d at 1348 (citing United States v. De Varon, 175 F.3d 930, 941 (11th Cir.1999)). If so, and only if so, the district court next determines whether the defendant’s particular role was minor in relation to other participants. Id. at 1348-49. These “other participants,” we have noted, are “only those participants who were involved in the relevant conduct attributed to the defendant. The conduct of participants in any larger criminal conspiracy is irrelevant.” De Varon, 175 F.3d at 944.
Yesquen’s argument that he was a mere pawn in a larger drug distribution operation is misplaced. The relevant conduct attributed to him in calculating his base offense level was his possession (and conspiracy to possess) with the intent to distribute of some 2,647 kilograms of cocaine. Yesquen’s sentence calculation does not reflect accountability under the Sentencing Guidelines for any other conduct related to a larger drug distribution scheme. Yesquen does not dispute — because he cannot dispute — that his role as a sailor was not minor in relation to the relevant conduct of possessing the cocaine aboard a drug boat whose mission was to deliver drugs for distribution. See id. at 948 (Carnes, J., concurring) (“Others may orchestrate or finance the crimes, furnish weapons or *798drugs, or profit more from the nefarious undertakings, but the drug courier ... [is] the one[] who actually carrfies] out [his] respective crime[].”). Because Yesquen fails to show that his role was minor in relation to the conduct reflected in the calculation of his base offense level, we need not address the second inquiry, namely whether Yesquen’s role was minor in relation to the seven other individuals found on the drug boat with Yesquen. The district court’s finding that Yesquen’s role was not minor is not clearly erroneous.
Similarly misplaced are Yesquen’s arguments concerning Dorvil and the Middle District of Florida’s alleged practice of granting minor role reductions to similarly situated defendants. Even if Yesquen had substantiated this latter argument, which he did not, it would not matter. As we have noted, a district court’s determination of a defendant’s role in an offense constitutes a factual finding. Ryan, 289 F.3d at 1348. We fail to see how findings as to defendants’ roles in a fifteen-year-old case from the Southern District of Florida — or even in more recent cases from the Middle District of Florida — have any bearing on the propriety of a finding in Yesquen’s case. Assertions that Yesquen was treated differently from similarly situated defendants really address the reasonableness of his sentence, the subject to which we turn next. See 18 U.S.C. § 3553(a) (requiring the district court to consider the need to avoid unwarranted sentence disparities).
II.
Yesquen argues that his sentence is unreasonable because the district court did not adequately consider his family’s poverty, the poor health of his son and mother in Colombia, and his low chances of recidivism. Yesquen further contends that his sentence was greater than necessary to achieve the purposes of sentencing and produced unwarranted sentencing disparities.
The Supreme Court’s decision in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), requires us to review sentences for reasonableness in light of the factors enumerated in 18 U.S.C. § 3553(a).3 Id. at 261, 125 S.Ct. at 765-66. Although the district court must be guided by these factors, “nothing in Booker or elsewhere requires the district court to state on the record that it has explicitly considered each of the § 3553(a) factors or to discuss each of the § 3553(a) factors.” United States v. Scott, 426 F.3d 1324, 1329 (11th Cir.2005). Indeed, “an acknowledgment by the district court that it has considered the defendant’s arguments and the factors in section 3553(a) is sufficient under Booker.” United States v. Talley, 431 F.3d 784, 786 (11th Cir.2005). A defendant challenging his sentence bears the burden of establishing the unreasonableness of that sentence in light of the § 3553(a) factors, and when a sentence falls within the guidelines range, we expect that sentence to be reasonable. See id. at 788.
*799Yesquen has not met his burden of showing that his sentence was unreasonable. At sentencing, the district court (1) stated that it considered all the sentencing factors listed in 18 U.S.C. § 3553(a); (2) considered Yesquen’s arguments regarding his family circumstances, but found that his sentence reflected the seriousness of his crime and the need to provide adequate deterrence; and (3) imposed a sentence at the low end of the guideline range. Moreover, by expressly stating that she was considering the § 3553(a) factors, the district court implicitly addressed Yesquen’s arguments that his sentence was greater than necessary to achieve the purposes of sentencing and produced unwarranted sentencing disparities. We cannot say that Yesquen’s sentence was unreasonably long.
AFFIRMED.
