The RMS Titanic is arguably the most famous ship to ever set sail - and not for a good reason. The mighty passenger liner, notably described as "unsinkable," sank in the North Atlantic on the morning of April 15, 1912, a mere two days away from its scheduled arrival in New York City. In doing so, the doomed vessel inspired a litany of retellings, at least one Oscar-winning film, and a handful of attempts at a real-life sailing sequel, including the Titanic II, which was due to make its maiden voyage in 2022.
