"She sounded a whole lot better today than she did yesterday," Nutt said about two hours after chatting with his 32-year-old wife.
Passengers were also given food, Nutt said, and some of the bathrooms are working. But the ship is dirty, Nutt said his wife told him.
"There's water and feces all over the floor," Nutt relayed. "It's not the best conditions. You would think Carnival would have something in place to get these people off the ship."
Passengers also are getting sick and throwing up, he said, adding that his wife told him: "The whole boat stinks extremely bad."
Melinda Ramos, meanwhile, said her father was laughing when she briefly spoke to him Sunday.
"He might be completely joking, but he said they're sleeping in tents outside," the 19-year-old daughter of Mary and Matt Ramos told The Houston Chronicle.
A similar situation occurred on a Carnival cruise ship in November 2010. That vessel was also stranded for three days with 4,500 people aboard after a fire in the engine room. When the passengers disembarked in San Diego they described a nightmarish three days in the Pacific with limited food, power and bathroom access.
Carnival said in a statement that it had cancelled the Triumph's next two voyages scheduled to depart Monday and Saturday. Passengers aboard the stranded ship will also receive a full refund, the statement said.
