¶1Defendants appeal their convictions, five-year sentences, and $50,000 fines for trafficking in marijuana. The defendants were among four people found on a 45-foot sailboat containing almost 7,000 pounds of marijuana. One of these individuals testified to the details of the entire importation scheme, which involved two boats and an off loading operation in the Bahamas. On appeal, defendants raise five points which we have reviewed and find to be without *1048merit. One of these points involves the initial stop of the boat by United States Customs Officials. Defendants contend that it was an invalid border stop. We hold, however, that the stop was justified as it was based on a reasonable suspicion that the craft was carrying contraband. See 19 U.S.C. § 1581(a) and United States v. Serrano, 607 F.2d 1145 (5th Cir.1979), cert. denied, 445 U.S. 965, 100 S.Ct. 1655, 64 L.Ed.2d 241 (1980).
¶2Another point concerns the trafficking statute, Section 893.135, Florida Statutes (1981), the constitutionality of which has been upheld in State v. Benitez, 395 So.2d 514 (Fla.1981). The court properly applied the mandatory sentencing provisions of Section 893.135. Defendants complain because one of their own group cooperated with the authorities, testified against them and received probation rather than jail time.
¶3AFFIRMED.
¶4. The person who testified against defendants was prosecuted in a separate case and was not convicted under the trafficking statute.
