Andrew Lock, the passenger who reported the story, spoke to CNN via Skype from Hong Kong.
According to Lock: "The cargo ship rolled over and almost capsized; we hit their bridge and crushed it, and we hit the side, creating a large vertical tear. The cargo ship then scraped down the side of our ship and disappeared into the fog behind us."
He continued to say that "after the impact...passengers gathered a few of their possessions and headed to the muster stations. "The crew was calm, but the passengers -- some were scared, or even frantic."
