Scout - The Sailing Sleuths

While Tom and his two friends are making plans for a vacation, Carl's father announces that he has acquired a sailboat, as part of a business deal. The three boys see the chance for a very unusual holiday.
Their peaceful sailing trip is sabotaged when they run into a gang of notorious carnival followers who put on sidewalk shows as a cover for more profitable sidelines. After a confrontation with the gang, the three sailors and Scout find themselves in trouble with the police.
