Lozman v. City of Riviera Beach, Florida

Summary

The Court held that a floating home without self-propulsion is not a 'vessel' under 1 U.S.C. § 3 because it is not designed to a practical degree for transportation on water. A reasonable observer examining the structure's physical characteristics would not consider it capable of practical transportation. Justice Sotomayor dissented, arguing the majority's test introduces subjectivity and the case should be remanded for factfinding.
