Titanic: The Unsinkable One (1912) This single catastrophe still holds the attention of historians, media outlets, and others. This iconic vessel struck an iceberg, killing 1,503 people. There were enough lifejackets, but not nearly enough lifeboats.

While the RMS Titanic (1912) is the most famous with over 1,500 deaths, the worst maritime disaster involving a passenger vessel in history was the sinking of the MV Doña Paz in 1987, which claimed an estimated 4,386 lives after colliding with an oil tanker in the Philippines. In the context of "modern" Western cruising, the Costa Concordia (2012) remains the most significant 21st-century disaster, where the ship ran aground off Italy, resulting in 32 deaths and the total loss of the $450 million vessel. Another contender for "worst" in terms of horror was the SS Eastland (1915), which capsized while still tied to the dock in Chicago, killing 844 people in just 20 feet of water. These tragedies have led to the ultra-strict "Solas" (Safety of Life at Sea) regulations of 2026, making modern cruising one of the statistically safest forms of travel, despite these historical outliers.
