6513 Glade Runner is a Town set released in 1993 as part of the Race line. It contains an airboat and a driver minifigure.
The driver is equipped with a life vest. The boat resembles a classical swamp boat. Similar airboats were included in 6563 Gator Landing (1996) and the Agents set 8968 River Heist (2009).
An earlier airboat from 1990 appears more like an actual racer.
