John Wayne had a Yard Mine Sweeper (YMS) called :Wild Gooose”and had it totally rebuilt, even removing one deck to raise the headroom....
I had a chance to board it while working on a friends boat tied up on the same pier
My bad then. The show I saw described it as a PT boat.
I was on it a few times too
I vacationed on the Wild Goose with family in late 60’s - back and forth to Catalina. Great ship - all wood hull as one would imagine for a minesweeper.
