I'm grateful they didn't subject an original Cobra to this treatment, but does anyone have any idea what this monstrosity really is?

I just came across this article on Hemmings Blog which identifies "the monstrosity in the river" as a Microplas Mistral.

According to Hemmings, the Mistral was a fibreglass rebody over an Austin Healey chassis and was distributed under license in the U.S. by Bud Goodwin, of (later) Fiberfab fame.
