The relatively new marina is part of the long delayed development of Watson Island.

With city of Miami and Miami-Dade fire boats deployed, the fire was fought from dockside and from the water.

A total of 40 firefighters kept water on the smoldering 120-foot yacht that was listing to its side.

They worked primarily in a defensive mode, containing the fire while protecting a number of other yachts moored nearby.
