At least a few hulls were sold, empty of all MILSPEC. They were rebuilt, re-powered (of course!) and had a mundane life, as if a racing thoroughbred horse was harnessed to a milk truck for morning deliveries.
One such was renamed RAINBOW and served as a day fishing boat out of Sheepshead Bay, Brooklyn, NY in the mid 50's. There were fish in the ocean near NY Harbor and down the New Jersey coast back then. My father was a compulsive lead-bouncer, and I went out with him many times. Possibly too many times... As a teenager I wanted to do my own stuff weekends; he wanted help carrying home the fish. (...on NYC buses and trolleys!!.. in soggy burlap bags!!) Times have changed...
Anyway, RAINBOW had an unmistakable PT hull, but a relative put-putt of an engine. It may have managed 10 to 12 knots. Never did go out on RAINBOW, but word around the bay said it rolled a lot on even flat seas. Pretty high freeboard, too. You had to reel in another 6 to 10 feet before you could lift a fish over the rail. Most boats were more stable, so their decks were closer to the water. We had a favorite boat before RAINBOW joined the 20 or so day boats, and went out on that one.
Today no fish. Sheepshead Bay has a small sail and motorboat marina well away from the end of the bay where the day boats docked. Times have changed...
Enjoyed the early "infomercial!"
