MacArthur’s PT boats didn’t sail to Australia—they only went 560 miles to Mindanao, then he flew the rest. Those boats had a max range of ~500–600 miles, even with extra fuel. Modern go-fasts are similar: 300–600-mile range, not the 1,700+ needed to reach the U.S. mainland from Venezuela. They’re for short hops, not trans-Caribbean crossings. No amount of fuel barrels makes that trip feasible without support ships. The comparison doesn’t hold—different missions, same range limits.
So where ARE the boats going? They are meeting up with cargo ships bound for Europe, specifically, Zelenskyy's nose.
