The 48-year-old actor set off with his friend and personal trainer Chris Feather on September 1 afternoon from Cold Spring Harbor on New York's Long Island but the pair got lost as night fell, reported Sun online.
"Thanks to Seth and the boys from the US Coast Guard for guiding the way... 4 hrs 30 mins, 7m(11.2km)," Crowe posted on Twitter the next morning.
US Coast Guard Petty Officer Robert Swieciki, who picked up the pair from shore, said, "He just needed a little bit of help, he just got a little lost. It wasn't really a rescue, really, more of just giving someone a lift."
