I believe that Quam bought the cat Active and raced it from Point Pleasant with Aoki as Benihana.
Then the boat was damaged at St.Augustine, was repaired and the alone Quam drove it at Key West.
Then the mud becomes denser.
In the 1983 Quam races with an identical Active in the livery to the old Benihana but with the red (of the boats of Quam) color to the place of the blue one.
Then to Key West after the first two a little positive races it puts in sale the boat (this results in an info).
You says that the 1983 Chrysler Laser was the ex repaired Benihana.
Then there was an Active Flap Jack with a different livery that very it resembles to that of the Thundercat posted above.
If really the 1983 Chrysler Laser was the former Benihana Quam could also have had three Active in his long career.
I'm waiting that someone clear the waters from the mud.
