Valentina Capuano, 30, had a grandmother and great uncle aboard the Titanic, which sunk in its 1912 maiden voyage. Her great-uncle Giovanni, a waiter aboard the cruise liner, died.
'It was like re-living history, it was horrible, I was really shocked," she told Italian newspaper La Repubblica. "I am still shaken up and get very upset when I think about what I've been through, I have heart palpitations."
Fights over lifejackets and the desperation of people leaping off the side of the ship into the sea has also been compared to the ill-fated Titanic voyage.
Other passengers have compared the delay in deploying lifeboats on the Concordia, meaning the vessel was tilted too far to use them, to the lack of lifeboats aboard the Titanic.
The Titanic had lifeboats for 1,178 passengers, despite 2,223 on board for her maiden voyage. 1517 people died in the disaster.
When it was launched in 1911, the Titanic was the largest passenger ship in the world, while the 951ft, 114,500 tonne Costa Concordia is the largest Italian-built cruise ship. It was built in 2006.
