The Ark
An interactive education and apologetics laboratory exploring what Genesis describes: dimensions, scale, capacity, structure, construction questions and seaworthiness.
Scale Laboratory / Interactive
How Large Was It?
Genesis gives the Ark’s proportions as 300 × 50 × 30 cubits. The exact modern conversion depends on the cubit value assumed. Adjust the control to see how that assumption changes the familiar dimensions; the rectangular diagram intentionally shows only the stated proportions, not an inferred hull shape.
standard uses an 18-inch working approximation. Ancient cubit lengths varied by place and period.
Floor area is a simple three-deck rectangular calculation for scale comparison. It does not assert the exact usable interior area of the historical vessel.
30 : 5 : 3
At this cubit setting, the Ark’s stated length is about 1.25× a football field including end zones.
Ark Features / Interactive
What Genesis Specifies — and What Reconstructions Add
Genesis gives several specific features of the Ark, but it does not describe every construction detail. Gold markers identify features stated in the text. Rust markers identify features that belong to modern reconstruction models. Select a numbered marker to see the difference.
Engineering Workbench / Feasibility
What Can Actually Be Tested?
A feasibility argument is strongest when it identifies the constraint first, then asks a testable question. ArkSearch separates calculations that can be modeled from historical details that the biblical text never supplies.
Stability & Survival
A vessel 300 × 50 × 30 cubits, intended to survive a catastrophic Flood rather than navigate a trade route.
How do plausible hull forms with those overall proportions behave under loading, waves, roll and pitch?
The exact bow, stern, keel, curvature or sea state experienced by the biblical Ark.
Naval-architecture question
Structural Strength
A very large timber vessel with multiple internal levels and compartments.
What framing, compartmentalization, timber dimensions and load paths could control bending, racking and local stresses?
Which ancient construction system Noah used or what specific species the translated term “gopher wood” denotes.
Structural-engineering question
Air, Water & Waste
Humans and animals remain aboard for an extended voyage; Genesis mentions an opening/tsohar and a side door.
What ventilation rates, water storage, feeding schedules and waste-handling systems are workable under different occupancy assumptions?
The precise internal ducting, labor schedule, storage containers or sanitation arrangement.
Logistics question
Animal Capacity
The Ark carries representatives of land-animal groups, with additional clean animals and birds specified later in the narrative.
How do capacity results change when assumptions about “kind,” animal age, enclosure size, food volume and deck allocation change?
A precise passenger count without first defining the biological and taxonomic assumptions used by the model.
Biology & logistics question
Key Questions
Explore the Ark’s Scale and Feasibility
Dimensions & Ratios
Length-to-width relationships, cubit assumptions, deck count and useful comparisons with buildings, fields, trains and ships.
Structure & Materials
What “gopher wood” may mean, how ancient large-timber construction worked, and where reconstruction becomes speculation.
Seaworthiness
Stability, proportions, waves, strength, ventilation and the difference between a survival vessel and a navigational ship.
Animal Capacity
How animal-number models depend on taxonomy, age, clean/unclean categories, storage assumptions and the purpose of the voyage.
Food, Water & Waste
Operational questions: provisioning, feeding frequency, water storage, ventilation and sanitation.
Design Models
Compare box-like, barge-like and hydrodynamically modified reconstructions while clearly labeling what is biblical text and what is inference.
Biblical Text & Reconstruction
What Genesis States—and What It Does Not
Genesis gives dimensions and several structural details, but it does not describe every feature of the vessel. Modern reconstructions can help illustrate scale and feasibility without claiming to reproduce the Ark’s exact appearance.
