Youtube user annanoli tells us:
Italian liner Principessa Jolanda sinks during launch because of defective ballasting and errors in calculations. Moreover many portholes were left open, and a donkey boiler exploded for the flood. The sistership Principessa Mafalda was launched two years later after extensive reduction in height. She was lost in 1927 for she lost tailshaft in mid-ocean and successive flood could not be stopped.
The wreckage of Principessa Jolanda was scrapped,engines salvaged were reutilized.
