The Ark, according to the Bible, was a massive boat built by Noah to save himself, his family, and a pair of every kind of animal from a catastrophic flood. While the exact dimensions of the Ark are not given in the Bible, the book of Genesis provides some general guidelines, which have been used by scholars and enthusiasts to estimate the size of the vessel. On the other hand, the Titanic was a luxury liner that famously sank on its maiden voyage in 1912, and its dimensions are well documented.

According to the Bible, the Ark was to be 300 cubits long, 50 cubits wide, and 30 cubits high (Genesis 6:15). The exact length of a cubit is not known with certainty, as it varied between different cultures and time periods. However, estimates based on historical records suggest that a cubit could range from about 18 inches to 22 inches. Using the lower end of this range, the Ark would have been about 450 feet long, 75 feet wide, and 45 feet high, while using the upper end would make it around 550 feet long, 90 feet wide, and 55 feet high.
The Titanic, on the other hand, was a marvel of early 20th century engineering, measuring 882 feet and 9 inches long, 92 feet and 6 inches wide, and 175 feet high from keel to funnel. The ship had a gross tonnage of 46,328 and could carry up to 2,435 passengers and crew.
Comparing the size of the Ark to that of the Titanic, it becomes clear that the Ark was much smaller in overall dimensions. While the exact size of the Ark is a matter of debate and interpretation, even the largest estimates put it at less than two-thirds the length of the Titanic and less than half the height. Additionally, the Ark was not designed for luxury or comfort but rather for utilitarian purposes, with a simple, rectangular shape and no amenities such as cabins, dining rooms, or swimming pools.
Despite its smaller size and simpler design, the Ark had to withstand the enormous forces of a worldwide flood, as well as provide shelter and sustenance for its occupants for over a year. The Bible describes how God gave Noah detailed instructions on how to build the Ark, including the type of wood to use, the number of decks to build, and the compartments to create for the animals and supplies. The Ark was also designed to be watertight and able to float, with a sloping roof and a door in the side.
In contrast, the Titanic was designed for speed, comfort, and luxury, with multiple decks, elaborate furnishings, and state-of-the-art technology for the time. While the Titanic was also designed to be seaworthy and able to withstand rough conditions, it was not built to withstand the catastrophic forces of a worldwide flood.
In conclusion, the Ark, according to the Bible, was a massive boat built by Noah to save himself, his family, and a pair of every kind of animal from a catastrophic flood. While the exact dimensions of the Ark are not given in the Bible, estimates based on historical records suggest that it was much smaller than the Titanic in overall size and lacked the luxurious amenities of the famous liner. Nonetheless, the Ark was a remarkable feat of engineering and faith, designed to withstand the forces of a worldwide flood and provide shelter and sustenance for its occupants for over a year.
