Biloxi police have closed off parts of Bayview Avenue.
The Biloxi Fire Department's boat is on the water still working to put out the smoke on the charred vessel.
Firefighters are using a firefighting foam to put out hotspots. The foam is an alternative to water, because using too much water could sink the boat.
The 30-foot cabin cruiser appears to have extensive fire damage. No word yet on when the boat fire started or whether anybody was on board.
