The Jet Express III was put into service in 2002 to help with heavy passenger counts during the weekends and holidays. Smaller than the Jet Express and Jet Express II, the Jet Express III is more economical to run in the spring and fall.
In 2005 the Jet Express III started service out of Sandusky with direct service to Put-in-Bay. In 2006, the Jet III began service to Kelleys Island, as well as Put-in-Bay. The Jet Express III offers service from Sandusky, to Kelleys Island and Put-in-Bay, which allows for an easy inter-island service between the two most popular islands on Lake Erie.
