I would have liked to add one more category of data for comparison with the name 'Type'.

Titanic Type - Luxury Cruise: Meant to cruise with all the luxury and occupancy per 10 sq feet was less than one.

Noahs' Arc Type - Rescue: Meant to just remain afloat and with occupancy to accommodate as much as possible.

Moreover where did the specific data for Noah's ark come from is another debate.
