CNN —The words “Titanic moment” are possibly the last thing you want to hear on a boat – but that was the phrase used by one passenger on board the Carnival Spirit cruise ship last week, after the vessel unexpectedly struck an iceberg. Videos of the incident circulated on social media in the aftermath, as multiple passengers filmed the moment the ship collided with the iceberg. The Carnival Spirit finished its seven-day Alaska cruise on Tuesday without interruption, returning to Seattle, Washington. Alaska’s waters are also known as some of the most challenging for cruise ships to navigate. “Today’s cruise ships are specifically built to sail a number of different waters,” Gray Faust told CNN Travel.
