Safety regulations

Passenger ships are subject to two major International Maritime Organization requirements : to perform musters of the passengers (...) within 24 hours after their embarkation and to be able to perform full abandonment within a period of 30 minutes from the time the abandon-ship signal is given.

Transportation Research Board research from 2019 reported passenger vessels, much more than freight vessels, are subject to degradations in stability as a result of increases in lightship weight. Passenger vessels appear to be more pressing candidates for lightship weight-tracking programs than freight vessels.
