"He just needed a little bit of a lift. He got a little bit lost," Coast Guard Petty Officer Robert Swieciki, who helped with the rescue, told Newsday Sunday. "When the sun went down, he didn't know where he was."
Swieciki said Crowe and an unidentified friend went out in kayaks Saturday afternoon, but asked the Coast Guard for help getting home when they spotted a boat around 10 p.m.
"He shouted at us from the beach, and he paddled up to us," Swieciki told the newspaper. "We took him to Huntington."
The 48-year-old New Zealand-born actor was shooting the biblical epic "Noah" in the area when the incident happened, Newsday said.
Crowe took to Twitter Sunday and thanked the Coast Guard "for guiding the way."
Best known for his roles in "L.A. Confidential," "Gladiator," "A Beautiful Mind" and "American Gangster," he will soon be seen in the big-screen musical "Les Miserables."
