Summary: written with AI from the case record.

What it's about
It also said the dispute remained live after Riviera Beach bought and destroyed the home because a court-ordered bond could preserve Lozman’s chance to obtain money if he prevailed.
The dispute asked whether a floating home moored indefinitely and supplied from shore qualified as a vessel, which would bring the case within federal maritime jurisdiction.
Question presented
Is a floating structure a "vessel" under 1 U.S.C. § 3, thus triggering federal maritime jurisdiction, if that structure is indefinitely moored, receives power and other utilities from shore, and is not intended to be used in maritime transportation or commerce?
What the Court decided
Holding
This case is not moot. The District Court ordered the floating home sold, and the City purchased the home at auction and had it destroyed. Before the sale, the court ordered the City to post a bond to ensure Lozman could obtain monetary relief if he prevailed. Lozman’s floating home is not a §3 “vessel.” 649 F. 3d 1259, reversed.
