To date, I have found no information on this subject on the web.
References
I learned about current surges through back-biased junctions the hard way (personal perspective above). The only reference I've seen related to these techniques is a 1970-era General Electric transistor manual that gives the ground rule that resistance should be placed in two of the three leads of every transistor. There is a literature on pulse overstress testing and rating of semiconductors that also may contain relevant information.
The hydrofoil patrol boat problem was solved by the application of normal electromagnetic interference (EMI) trouble-shooting techniques described in EMI books such as the book by H. W. Ott and other EMI books in the booklist, combined with a knowledge of the trouble caused by inadvertently forward-biased junctions.
Do not use this information for design without independent verification of the information.
