Best Answer: While some are of the opinion that only the Titanic really existed, the Titanic was more than 800 feet long overall, about 92 feet wide and had a moulded depth of around 60 feet. The Bible gives the size of Noah's Ark as 300 cubits (507 feet) long, by 50 cubits (85 feet) wide and 30 cubits (about 50 feet) high. The Titanic was about twice as long as Noah's Ark,but both vessels were close to the same width.Since the Titanic existed it wins.
