In 1981 Porsche assisted Joest in building their own version of the ‘Moby Dick’ 935 (#JR001), in much the same way as they helped Kremer in their construction of a new 917 at that time. After having Mass -who drove the original Moby- race the car only three times in Germany Joest sold it to Momo owner Gianpiero Moretti who used it extensively in Europe and America until the end of 1983, when it was still achieving good results in the IMSA series.
We see it here at the Silverstone Six Hours in 1982, where it started from 15th in the hands of Moretti/Baldi and ended 7th overall and 1st in class. This car was based on a factory 935/78 and looks a bit different to the original works Moby of 1978.
The second Joest 935-81 (#002) had a much shorter career, with four races in 1982 and two in 1983. It ran all of these for the John Fitzpatrick team and it is shown above on its maiden outing at Le Mans, where it was driven by the team owner and David Hobbs to 4th overall and a class win.
A number of differences will be noted between the two cars, such as the mirrors, air intakes and rear wing. It was the breakage of the latter at high speed during the Riverside Six Hours that caused the crash that claimed the life of three times Porsche Le Mans winner Rolf Stommelen, who had just taken over the car from Derek Bell. This was one of a number of occasions when the two cars competed simultaneously, #001 going on to finish 3rd.
