TONY'S U-DRIVE BOATS, Atlantic Highlands, NJ – 1953 Tony's U-Drive Boats were very popular at the time since most marinas and landings only offered small rental skiffs with outboard motors. At 26 feet in length, the U-Drive boats were much larger and were powered by 125 HP inline 6-cylinder Chrysler Marine engines. They offered the speed and roominess that only boat owners had previously enjoyed.
