We now move on to discuss particulars of the ark ...

God gave Noah specifications for how the ark was to be built. It is interesting that the ratio of the given dimensions has been found by modern ship builders to represent a very stable configuration. Remember that the ark was not really a "boat". It didn't need a power source to move it along (like sails), nor a rudder to steer it, nor did it need to move through the water efficiently. It simply needed to float and be as stable as possible. It only needed to be sea-worthy for one year. The bottom of the ark may have been made out of large logs to give it extra stability. It did not have any particular place to go!

The ark "window" was actually a long "slot" under the roof eaves. It was a particularly important feature, as it provided needed ventilation and illumination.

The exact type of wood used is not known. It may have been teak, cypress, or some other hard or hardened wood.

The "pitch" with which the ark was sealed may or may not have been petroleum-based. It is believed that some oil may have existed before the flood, produced from non-biological sources. Most oil is believed to have formed from plant material uprooted and buried by the flood.
