This, the first of only two Reinhold Joest-built "Moby Dick" replicas, was built from factory-supplied plans by factory supplied personnel at the Joest facility over the winter of 1980-81.

The car was raced by Jochen Mass for the Joest Racing Team in 1981 and scored victory at Hockenheim before being sold to Joest's customer, Dr. Gianpiero Moretti. Moretti raced the car in IMSA events in 1981 and then, with Mauro Baldi, undertook some World and German National Championship races in 1982 with some good results. In 1983, Moretti raced the car again in the U.S. IMSA Camel GT series with the 1984 Daytona winner, Sarel van der Merwe. After this, "Moby" was retired, as Moretti had taken delivery of a March 82G.

There were only four 935/78 "Moby Dicks" built. Of the first two (built by Porsche in 1978 and run by the factory team) one is in the Porsche museum and the other is dismantled awaiting restoration. Joest, with the assistance of Porsche, built the two other "Mobys" in 1981, chassis 002 being destroyed at Riverside in 1983.
