After the grounding of Costa Concordia, the world of cruise travel took a good hard look at everything they were doing in the way of safety. A comprehensive Operational Safety Review of passenger safety measures resulted in new policies that promised to address safety concerns. Those policies were adopted by members of the Cruise Lines International Association (CLIA), which covered most of the major cruise lines we know about. Recently, the International Maritime Organization (IMO), which oversees those and other cruise lines worldwide, adopted the same rules for all ships sailing, effectively standardizing safety rules for all.
But seasoned cruisers who have sailed a number of times, those who were undeterred by safety-related concerns, don't seem to care all that much and have continued sailing, as planned, without hesitation.
