Build report: Scratch-build 1/700th scale Noah’s Ark

reyarkmain.jpgTim Reynaga joins us today with his first contribution, a very interesting scratchbuild of Noah’s Ark. Of particular interest is the research Tim put into this, not just from Biblical sources, but also ancient texts that support all the details of the Ark story told in Genesis. And on top of all that, it’s just a darn clever build. Thanks to Tim for his gracious permission to republish this, and to Scott Van Aken of Modeling Madness where this first was published. Look for more nautical subjects in the future from Tim.

Some years ago as an undergraduate at UC Berkeley I found myself enrolled in an ancient Mesopotamian literature class. As a History major it wasn’t my first choice, but the class was reputed to be easy and reading those wild old Sumerian, Akkadian, Babylonian, and Hebrew stories sounded like it might be a kick. Unfortunately, it was also one of those innovative classes where you couldn’t get by just attending the lectures, reading the assigned materials, writing term papers and passing the exams… you actually had to do some sort of “creative” final project as well.

As the end of the term neared, the dreaded presentations began: some of my classmates made cuneiform inscribed clay tablets (Literature majors, of course); some fratboys in the class concocted some positively vile (but, they assured us, authentic) Sumerian beer. One truly frightening person even composed—and performed— a series of Assyrian style magical spells, incantations, and curses (it was, after all, Berkeley!) Everyone seemed to have ideas, and they were all so damned creative! But me? My approach to the problem had been to think about it as little as possible until, as the end of the semester inexorably approached, the awful realization came that I had to put something together fast.

During the course of the term I had been fascinated by the numerous versions of the story of the Great Flood, and of course as a ship modeler I was particularly intrigued by the Ark. Was such a vessel really possible? What might it have looked like? With no other ideas, a looming deadline and the prospect of academic probation to motivate me, I re-read the Sumerian Deluge Myth, Akkadian Epic of Gilgamesh, Babylonian Atra Hasis Epic, and the Hebrew Flood story from the book of Genesis.

ark_plans.gifEach account provided its own interesting perspectives including details of construction, interior structure, launching of the craft and the like. The best known version is the one found in the ancient Hebrew book of Genesis, which also provided the most detailed specifications of the actual vessel:

ark_plans2.gif“…And God said unto Noah, Make thee an Ark of Gopher wood: rooms shalt thou make in the Ark, and shalt pitch it within and without with pitch. 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. A window thou shalt make in 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.” (Genesis 6:14-16).

Given 18 inch “cubits” (a standard ancient measure representing the approximate distance from the average man’s elbow to his fingertip), the biblical Ark would have been about 450 feet long, 75 feet wide, and 45 feet high. It had three interior decks, a door on the side, and some sort of window topside, with the whole wooden structure sealed with pitch.

The Kit
reyarke.jpg Aside from a few cutesy children’s toys, there were no kits available for this one. Now I’m no scratchbuilder, but this was a pretty simple project and I was under the gun… so I figured I’d give it a go. In part because of my limited scratchbuilding skills and because I had to get this thing completed over a single weekend, I opted for a very simple layout with flat surfaces and gentle slopes. I reasoned that the unpowered vessel would probably have resembled a barge rather than a seagoing ship. In fact, the ancient Hebrew word for the Ark, tebah, does not even mean “boat” or “ship”. It is etymologically related to the Egyptian word db’at, meaning “box” or “chest” or even “coffin”, suggesting a squarish, barge-like craft. (Interestingly, the word is only used one other place in the Bible, to describe the casket in which the infant Moses was cast adrift in the Nile.) Also, the 4,700 year old Akkadian Epic of Gilgamesh (Tablet IX, line 59) and the Babylonian version of Atra Hasis (Tablet III, lines 25-6) both refer to the Ark’s “square decks”. Finally, ancient Mesopotamian traditions held that Ziusudra, Atrahasis, and Utnapishtim (the Sumerian, Akkadian, and Babylonian “Noahs”) came from the city of Shurrupak on the Euphrates River, so a river barge-type design would have been a natural.

reyarkf.jpg I made some quick 1/700 scale measurements and set to work cutting the pieces out of plastic sheet. Evergreen .040 inch thick v-groove siding with .030 inch spaced grooves (product #4030) served for the hull, and the roof parts came from .030 inch thick passenger car siding with .025 inch grooves (product #3025). I like the easy to work Evergreen plastic, and the mass of delicate grooves on the sheets would nicely simulate the wooden construction of the vessel.

Assembly began with bending the roof downward along its centerline over a straight edge to fit over the peaks of the bow and stern parts. These I cemented into place after having similarly bent them to fit the curves at the ends of the roof. Two interior bulkheads made from the .040 inch hull material were included for added rigidity. To my surprise, these showed through the roof after the cement had dried. The cement applied to the thick bulkhead edges had slightly distorted the thinner material of the roof. Still faintly visible on the exterior of the completed model after painting, they subtly suggest an inner structure. A happy accident!

reyarkh.jpgAccording to Genesis 6:16, “A sohar thou shalt make to the Ark and in a cubit thou shalt finish it above…” The obscure ancient Hebrew word sohar is traditionally rendered as “window”. A window usually means an aperture in a structure, but the sohar is “above” the main structure by one cubit. For this to be so, the opening would have to be part of a separate section elevated above the main roof. I reasoned that the sohar must have been this structure with ventilation openings rather than a window as such. This would also explain the Babylonian account’s “…let it be roofed over above and below” (Atra Hasis Tablet III, line 31), “so that the sun shall not see inside it”, which apparently distinguishes the roof of the sohar above from the vessel’s main roof below it.

reyarka.jpgThe roof of the sohar was cut and formed just like the roof of the hull, the sides fashioned from Evergreen HO scale ladder kit parts (product #201), which came precut with small rectangular notches. When attached beneath the sohar roof these notches became uniform rectangular vents running the length of the ship, providing a nice see-through effect when viewed from directly abeam. This all may sound complicated, but it took only a single afternoon to cut out and cobble together these twelve simple parts!

Colors & Markings
reyarkc.jpgPainting was even easier than the construction. According to the Bible, the Ark was sealed “…within and without with pitch” (Gen 6:14). In the Epic of Gilgamesh, “the little children [carr]ied bitumen…six sars of asphalt I also poured inside…” (Tablets XI, lines 54 and 66), and the Atra Hasis narrative says, “…let the pitch be tough and so give (the vessel) strength” (Tablet III, line 33). It would have been most reasonable to paint the Ark gloss black overall, but I opted instead to paint it a “Gopher wood” brown (otherwise known as Tamiya acrylic flat brown XF-10) with the seams “caulked” in a black enamel wash to give the model a more wooden appearance. A light drybrushing of lightened base color and a misting of gloss varnish to give the ship a slightly wet look completed my little weekend wonder.

Final Construction
Since I was on track with my timetable I took the extra step of making a heavy, rolling sea out of drywall spackle on an old trophy plaque to add interest to the very plain looking model. The water was painted with a simple blend of Testors Non-Specular Sea Blue (FS 35042) and white. The vessel was heeled over just a bit with the lower one-third trimmed away to give it a natural looking “sit” in the swells.

reyarkg.jpg There it was, quick and easy. Like the original, my Ark was a no-frills project built on a strict timeline to avoid a catastrophe. Although speculative, I figured my interpretation was reasonable enough based on the ancient literary evidence. Anyway, who’s to say I got it wrong? At least my professor approved it, and that was good enough for me!

Tim Reynaga’s Bio:
I am married with four kids (three daughters and a son) and I work as a program analyst for the State of California’s Employment Development Department. My wife is an elementary school teacher and we all attend the Newman Catholic Community Church here in Sacramento.

I’ve been building models since I was five years old (my first model was a lunar module bought for a dime from a magazine ad). I’m mostly interested in ships but will happily put together just about anything: tanks, aircraft, figures… I even built an old Aurora White Tailed Deer a few months back. This hobby has been a lifelong pleasure for me–I never seemed to have grown out of it like all my childhood friends did!
