Normally to be named Diamond Princess during construction, but swapped names with her sistervessel because a major fire occured through the original Diamond Princess (presently sailing as today's Sapphire Princess) during construction, leading to a construction delay.
Both sister ships were being constructed at the same time, so the original Sapphire assumed the role of Diamond.
This name swap assisted in keeping the delivery date of Diamond Princess on time, and kept Sapphire Princess on schedule as it was nearing completion early |
