How Much Did Noah's Ark Weigh?

"The waters prevailed and increased greatly on the earth, and the ark floated on the face of the waters"

Boats and ships float by means of the principle of physics known as buoyancy - the force of displaced water pressing against the outer hull as it attempts to return. A floating vessel will sink into the water only so far as to displace an amount of water that is equal to the total weight of the floating vessel.

Container Ship

Noah's ark had no engines or sails. All that it needed to do was to float. As such, it could have been simply rectangular in design, as it apparently was, according to the historic account:

Noah's Ark

"6:13 And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.

6:14 Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch. 6:15 And this is the fashion which thou shalt make it of: The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits. 6:16 A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it.

6:17 And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die. 6:18 But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee. 6:19 And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female. 6:20 Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive. 6:21 And take thou unto thee of all food that is eaten, and thou shalt gather it to thee; and it shall be for food for thee, and for them.

6:22 Thus did Noah; according to all that God commanded him, so did he." (Genesis 6:13-22 KJV)

Boeing 747 Inside Noah's Ark

Although simple in design, the ark of Noah was nevertheless very large, as shown in the comparison illustration above. The ark was about 140 meters (450 feet) long, 23 meters (75 feet) wide and 14 meters (45 feet) high.

The ark had three inner decks ("with lower, second, and third stories shalt thou make it") and a single door in the side ("the door of the ark shalt thou set in the side thereof"). As such, the illustration of the ark at sea shown above is reasonably accurate.

So what was the approximate weight of the fully-loaded ark?

With the position of the side door as the key determining factor, the ark would have been designed (the LORD was the first naval architect) to not sink beyond about one third of its height i.e. about 15 feet. With its near-rectangular shape, that would mean a volume of 450 feet, times 75 feet, times 15 feet for a total of 506,250 cubic feet i.e. ark would have displaced about 506,250 cubic feet of water.

What does 506,250 cubic feet of water weigh?

A cubic foot of fresh water weighs about 62.4 pounds, while a cubic foot of salt water weighs about 64 pounds. The waters of flood were not just rainfall, they were also from the "fountains" of the deep (see the Fact Finder question below), so along with the saltwater oceans that already existed, it was much more likely that it was salt water.

506,250 cubic feet of salt water at 64 pounds per cubic foot totals 32,400,000 pounds, or 16,200 tons.

What is that in comparison to modern-day ships? The ship in photographs below is the Canadian aircraft carrier HMCS Bonaventure (Canada had 3 aircraft carriers in the post World War Two era). As it happens, the displacement of the "Bonnie" was officially listed as 16,257 tons - the same as our calculation for Noah's ark.

This Day In History, April 18

1025: Boleslaw Chrobry (known as Boleslaw I the Valiant) became the first King of Poland (in nearly all languages, the word "king" means father of a kin; the original true meaning of "patriotism" means faithful to the father; see The Patriotism Prophecy and The Only Political Party That's Going To Survive).

1328: Holy Roman Emperor Louis IV ("Louis the Bavarian"; see The Holy Roman Empire Of The German Nation) deposed Pope John XXII in Rome in a quarrel over who had superior authority (see Emperors and Popes). Peter of Corbara was appointed anti-pope as Nicholas V (see Antipopes).

1521: The trial of Martin Luther began its second day during the assembly of the Diet of Worms ("diet" is from the Latin word for day, used to refer to a daily assembly, while "Worms" is the English rendering of Vorms, a city in Germany). Luther refused to recant his anti-pope teachings, while keeping, as the "Protestant" world has done ever since, nearly all of the Church of Rome's anti-Christ doctrines (see Antichristians).

Martin Luther

1689: British Chief Justice Judge George Jeffreys died in the Tower of London. He presided over the "Bloody Assizes" following the Monmouth Rebellion of 1685.

1897: The Greco-Turkish War was declared between the Ottoman Empire and Greece.

1906: A powerful earthquake struck San Francisco (then a relatively small town). It killed more than 1,000 people and left over 200,000 people homeless.

1912: The British liner RMS Carpathia arrived at New York with 705 survivors of the RMS Titanic.


1943: While traveling in a bomber, Japanese Admiral Isoroku Yamamoto, the planner of the attack on Pearl Harbor, was killed after the plane was shot down by U.S. P-38 fighters (see also The Art Of War and Why Was Korea Divided Into North And South?).

1946: The League of Nations was dissolved. It was replaced by the United Nations.

1949: The passing of the Republic of Ireland Act.

1950: The first transatlantic jet flight, a BOAC (British Overseas Airways Corporation, today British Airways) Comet airliner from London to New York (see also Who Was The First To Fly? and The Rockets' Red Glare).

1951: France, West Germany, Italy, Belgium, the Netherlands and Luxembourg signed a treaty to establish the European Coal and Steel Community.

1954: Colonel Gamal Abdel Nasser became the leader of Egypt.

1955: Albert Einstein, German-born scientist, died at age 76. He formulated the Theory of Relativity (see also Einstein's Holy Spirit Formula) and won the Nobel Prize for Physics in 1921 before fleeing Germany in 1932 to escape the Nazi persecution of Jews (regarding Adolf Hitler, see Why Does Satan Love Liars?).

Albert Einstein

1974: A Washington court issued a subpoena on U.S. President Richard Nixon to produce tape recordings and other "cover-up" evidence demanded by prosecutors for their investigation of the Watergate crimes (see also The Impeachment Of The President).
