Four banks of four vertically arranged which resulted in a real crankshaft problem: they broke!
There was a ditty that ran "Harder, Darter, Trigger, Trout, Always In and Never Out." They had to lengthen
the class (13 ft?) and replace the pancake with a mod-speed 8 (?)
Last hull with the Pancake was the Albacore which could not be lengthened without destroying
the hydrodynamic efficiency of the hull form.
I was at Eleuthera when the Albacore came down for trials in the Tongue of the Ocean and
on top of 22. It looked a lot like a nuc when not operating the Pancake.
"Harder, Darter, Trigger, Trout, Always In and Never Out." Ha! I remember this ditty from my early days in Bermuda (1973-75). The "old dudes" talked about it (Tribble, Ellis, Cable et al). And I now recall discussions about the "Pancake" arrangement. You guys are amazing in your memory recollections. Lets all have a beer one day.
