According to some modern scientists, and I quite agree, the land mass of the earth was largely one great super-continent with all its landmass connected. Some would divide this landmass into two super-continents with the northern, Laurasia, connected to the southern, Gondwana. Of course, the ratio of land to sea is entirely subjective reasoning. That is, did we have more land mass and less ocean before the Flood? We don’t know, but for the most part it is generally agreed that most, if not all the earth’s landmass was connected.
Assuming the above is true, there would not have been a great need for ocean travel for trade or military purposes. Migration and trade could be conducted throughout the globe without the necessity of sea travel. Moreover, in as much as this super-continent did not have very high mountain ranges, such as the Alps, Himalayas, Andes or Rockies, migration and trade could be conducted rather easily throughout the world without the use of the sea. This does not preclude coastal trade, but great ships would not be needed for such trade or migratory voyages.
This understanding receives some support from the impracticability of the seafaring model proposed by the Babylonian cube-like vessel, which, according to the Gilgamesh Epic was used to save all aboard. Yet, such a vessel would continually rotate and capsize in the open seas. A complete nautical ignorance is betrayed in such an account, which causes us to ask: if sea travel was generally done between countries and continents for migratory, trade and military purposes, why is the Gilgamesh model so bereft of nautical intelligence?
On the other hand, if sea voyages were not so frequent in ancient times, where did Moses receive his information about the Ark’s dimensions? Where did he copy such a description of its structure, if it needs to be concluded that he did copy his information? The then current flood legends display a great ignorance of nautical intelligence!
In a previous blog-post I replied to some modern arguments made against the seaworthiness of Noah’s Ark and concluded by referring to a study made by Dr. Seon Won Hong, a naval architect who found that the Ark would have been stable, safe and reasonably comfortable for those aboard. Knowing this, why should we believe Moses should know such remarkable naval, architectural design? If the Ark had been taller, it would be unstable. If the Ark had been longer, it would have broken up in the sea, and if one changed the width to length ration—wider or shorter—the Ark would have been a lot less comfortable for those aboard. How did Moses know this, if he merely copied ancient flood accounts which don’t have the Ark’s specifications, or if he simply imagined them?
The Ark’s ratio of 6 to 1 (450 feet length by 75 feet width) would tend to keep the vessel in line with the prevailing ocean currents. This would make it virtually impossible to capsize, since it would have to be turned completely vertical to do so. The Ark was not designed to sail from point “A” to point “B” but was designed to simply float and save Noah’s family and all the air-breathing animals aboard through the great flood that came upon the earth. Its flat bottom would give it about 1/3 more cargo space that regular ships of its size, which would have sloping sides. So, given the unlikelihood ancient ocean sea voyages and the practical and nautical feasibility of the description of Noah’s Ark in Genesis 6, how should we account for Moses’ knowledge of such a seaworthy vessel, being so appropriate for the intended use?
 Dr Seon Won Hong was principal research scientist when he headed up the Noah’s Ark investigation. In May 2005 Dr. Hong was appointed director general of MOERI (formerly KRISO). Dr Hong earned BS degree in naval architecture from Seoul National University and PhD degree in applied mechanics from University of Michigan, Ann Arbor.
