Many Christian web sites state that a Cunard steamship named the
Eturia, built in 1883, was the first ship that was longer than Noah's Ark.  I
have been unable to find out how long the Eturia was, or if it really
existed at all.  I can only find references to the Etruria (note the
extra R).

My question is - did the Eturia and the Etruria really exist, and what were their
dimensions (length, width, tonnage)
