D.Puerto Rico
AFFIRMED.
Before Torruella, Circuit Judge, Campbell, Circuit Judge, Skinner,* District Judge.
Per Curiam.


1
Appellant Ricardo Jose Noche and three co-defendants pled guilty to aiding and abetting the knowing and intentional possession of 2,000 pounds of marijuana with intent to distribute.  On May 28, 1992, the district court sentenced appellant to 78 months in prison, five years of supervised release, and a $50 fine.  Appellant now asserts that the district court erred in refusing to grant a downward adjustment to his sentence as either a minimal or minor participant pursuant to the United States Sentencing Guidelines ("U.S.S.G.") § 3B1.2(a) and (b) respectively.


2
Appellant has the burden of proving his entitlement to a downward adjustment to his sentence.  U.S. v.  Ocasio, 914 F.2d 330, 332-33 (1st.  Cir. 1990).  Only defendants who are "plainly among the least culpable of those involved in the conduct of a group" are entitled to a downward adjustment as a minimal participant, U.S. v.  DiIorio, 948 F.2d 1, 5 (1st Cir. 1991) (quoting U.S.S.G. § 3B1.2(a), Application Note 1), and to be a minor participant a defendant must be less culpable than the average participant.  U.S. v.  Rosado-Sierra, 938 F.2d 1, 1 (1st Cir. 1991).


3
We review a district court's determination of whether a defendant played a minor or minimal role in an offense under § 3B1.2 only for clear error.   DiIorio, 948 F.2d at 5.


4
In the present case, both parties agree that appellant and his co-defendants were on a vessel that contained 2,000 pounds of marijuana;  they aided and abetted the possession with intent to distribute that marijuana, and expected $3,000 in return.  In addition, during his plea, appellant acknowledged that he knew that the ship was to be used to smuggle marijuana.  From this evidence, the district court reasonably determined that appellant was an active and essential participant in the offense.


5
Moreover, appellant never alleged that he was less culpable than his co-defendants.  Instead, he attempted to argue that the incident was part of a larger drug smuggling scheme in which he played a minor role.  The only evidence that he offered in support of this theory, however, was testimony that there was a captain of the ship who abandoned it due to engine trouble, and the fact that he was promised payment for his role in the crime.  Appellant could point to no other individuals who were part of the alleged scheme.  He offered only speculation that if there was a captain and someone who paid him, there must have been a larger criminal structure.


6
The court committed no clear error in determining that appellant failed to prove a larger criminal scheme and that appellant played more than a minor role in the charged offense.  Thus, it correctly denied the downward adjustment to appellant's sentence.  We affirm the district court's judgment.


7
Affirmed.
