Thriller (the airex one) became Coors Light Silver Bullett (Craig Barrie) then Ferrari. Confirmed in a Jaguar write up in Hotboat.
The new lighter Ferrari became Toshiba then Snack Attack as confirmed by the co driver of Snack Attack at the 2001 Key West race, and also confirmed by an article on Toshiba which states it was the ex-Ferrari that raced at the 1990 Monaco Worlds.
Another report states that 1990 Bay City had both Ferrari boats,the brand new lighter one and the old Ferrari (crewed by Mandy`s brother David and Craig Barrie).
I would have liked to post the evidence ,but the files are too large to post.
There are many unanswered questions on the history of Jaguar boats,and one day will try to sort them out.
