Design beyond the minimum

The sea remains a force that technology has not mastered. Large modern ships may have lifeboats, rafts, and trained crews, but Symphony of the Seas' cited complement of 8,880 people illustrates how mass evacuation still depends on the hull retaining buoyancy long enough. Titanic's enduring lesson is that compartmentation and structural resilience must buy the time on which every evacuation plan depends. As passenger ships continue to grow, the consequences of regulatory lag grow with them. Designers need room to build the fullest practical safety margin before the rules catch up.
