In September of 2015, this website launched the Noah's Ark Possibility Project (NAPP) with the stated purpose to
investigate whether an ark as specified in Genesis 6:14-16 could possibly have had sufficient carrying capacity to save two of every
kind of bird and land animal, both male and female. Beyond the physics of the ark and animals, there are many aspects relating to
this subject that cannot be answered by scientific investigation as they relate to the supernatural actions of God. From all biblical
accounts, God is all powerful, all knowing, and not just a casual observer but active in the world He created. The ark and the world
wide flood depend on such a God.
Four of the more common objections to the Noah’s ark account are (1) the ark could
not possibly carry all the animals, (2) Noah could not have possibly gathered all the animals from around the world, (3) some of the
animals (e.g. lions, tigers) would kill others while on the ark, and (4) there is insufficient water on earth for a worldwide flood
covering the highest mountains. This project as stated will address objection 1. Objection 2 is answered in Genesis 6:20 as God says
that the animals will come to Noah to keep them alive. Objection 3 is like the latter objection in that God who can cause the animals
to come to the ark can also keep them safe on the ark. Objection 4 attempts to set limits on what God can do. How you view the biblical
flood account really depends on your view of God.
This article will be updated from time to time as this project
progresses. Progress so far on this website is as follows:
“And of every living thing of all flesh, you shall bring two of every kind into the ark, to keep them
alive with you; they shall be male and female. Of the birds after their kind, and of the animals after their kind, of every creeping
thing of the ground after its kind, two of every kind shall come to you to keep them alive.” 
you seven of every kind of clean animal, a male and its mate, and two of every kind of unclean animal, a male and its mate, and also
seven of every kind of bird, male and female, to keep their various kinds alive throughout the earth.” 
with these texts, the ark was to be loaded with two of every kind of bird, male and female, and land animal, male and female. In addition
to the two of every kind, six male and female couples of all clean animals were to be loaded making a total of seven for clean animals. List A
is a partial list of animals designated as clean and unclean.
Table A - Total Adult Animal Weight Estimates
Total Weight of Animals on the Ark (lb.) 19,414,766 so far
Ark's Carrying Weight Capacity (lb.) 60,880,000
Table A is being generated based on incomplete information. Sources of error include (1) the fact that all
kinds of land animals and birds may not have been identified, (2) some kinds categorized as species may not actually be distinct kinds
resulting in double counting of certain kinds, (3) snakes in Table 2 and the amphibians of Table 4 may not have been on the ark as
they can swim, (5) the extant invertebrates could possibly have survived on floating debris and did not require the ark, (6) the weights
for the animals in Tables 1 to 19 are estimates, some or all the animals may not have been fully grown, and (8) some animal kinds
may have been extinct before the flood. In spite of these and other uncertainties, many questionable items have been included
to help validate the results. The reason for the shift from species to genera for extinct prehistoric animals is discussed
in the preamble to Table 8. Animals living exclusively in a marine environment have been excluded.

Coating: ark covered inside and out with pitch or tar
Door on side: God closed it after all aboard 
Window: opens and
Covering: ark had covering 
Although the dimensions of the ark are given, the shape of the ark is uncertain. As navigability is not required, buoyancy, stability,
strength, keeping unwanted water out, and ease of construction are the main design considerations for the ark’s exterior. The simplest
shape to meet these requirements is to make the ark nearly rectangular in plan and profile.
According to Archimedes’
Principle, the buoyant force is equal to the weight of the fluid displaced by an object. As the draft for the ark has not been specified,
it will be necessary to assume one. Since the height of the ark is specified as 45 feet, let’s assume a draft of 30 feet to begin.
Water weighs about 62.4 pcf.
Based on the above assumptions:
The buoyant force on the ark = 30 ft. x 450 ft. x 75 ft. x 62.4 pcf. = 63,180,000 lb.
Ark’s Dead Weight:
of wood is uncertain as there is no description of gopher wood brought forward to modern times. It may be assumed that gopher wood
was relatively easy to work with and therefore is some sort of softwood with a density of 30 pcf. No increase in weight for material
being water logged is necessary because of the protective tar or varnish coating specified. Size and placement of the ark’s components
are not known but a reasonable assumption is that they take up no more than five (5) percent of the ark’s volume.
Based on the above assumptions:
The approximate dead weight of the ark = 450
ft. x 75 ft. x 45 ft. x 30 pcf. x 5%
= 2,278,125 lb.
Say 2,300,000 lb.
Ark’s Carrying Weight Capacity:
weight capacity = ark’s buoyancy – ark’s dead weight
= 63,180,000 lb. – 2,300,000 lb. = 60,880,000 lb.
Ark’s Cargo Weight Capacity:
Cargo weight capacity = ark’s buoyancy - ark’s dead weight – ark’s store’s weight
Besides the cargo weight capacity
there are other factors such as volume, floor space, and sufficient air circulation for the animals that must be considered.
“And as for you, take for yourself some of all food which is edible, and
gather it to yourself; and it shall be for food for you and for them.” 
The above is the only reference of food
for the ark. It states that all kinds of food are to be loaded onto the ark but is silent as to the amount. There are at least three
possibilities here as follows:
1. The amount of food to last for the year plus on the ark is specified to Noah
but not recorded.
2. The amount of food to last for a short period of time is specified to be loaded onto the ark
as God will cause most or all of the animals to hibernate.
3. The food is to be multiplied in similar fashion as
performed by God for the widow of Zarephath,  Elisha and the multiplication of the oil,  or in Jesus feeding of the 4,000  and
Although possibility 1 can be estimated based on the weight of the animals and food requirements for
various animals, the fact that possibilities 2 and 3 exist makes that calculation unnecessary. After all, there is no reason to assume
that the animals were sustained for the year plus on the ark by natural means.
Neither is the amount of water to
drink specified. The possibilities here are similar to those regarding food. Also, perhaps the water just outside the ark was suitable
