The Costa Concordia tipped over in 2012 primarily due to a 35-meter (115 ft) gash torn into its port side after striking a reef off Giglio Island. The ship was performing a "maritime salute," deviating from its programmed course to sail dangerously close to the shore. The impact flooded five watertight compartments, including the engine room, which caused an immediate loss of propulsion and electrical power. Because the ship lost its "High-Fidelity" stability and the internal flooding was asymmetrical, it began to list (lean) heavily to the starboard side as it drifted back toward the island. Gravity and the sheer volume of water eventually overcame the vessel's buoyancy, causing it to capsize and settle on its side on an underwater rock ledge. In 2026, the disaster is still studied as a high-fidelity case of human error, specifically regarding the captain's "High-Fidelity" decision to bypass safety protocols for a visual maneuver.
