It didn't need to hold a course. There was nowhere to go and no propulsion was needed to go nowhere.
It only needed to stay afloat for a year.
how did you arrive at the figure of one year afloat.?
The beginning of the rain/flood was in the second month (Genesis 7:11) and still took some time
before the waters were high enough to actually float the ark.
Genesis 7:17( KJV)
"And the flood was forty days upon the earth; and the waters increased, and bare up the ark, and it was lift up
above the earth".re: actual time AFLOAT...
Genesis 8: (KJV)
3 "And the waters returned from off the earth continually: and after the end of the hundred and fifty days
the waters were abated.
4 And the ark rested in the seventh month, on the seventeenth day of the month, upon the mountains of Ararat."
Genesis 8: NLT
3 "So the floodwaters gradually receded from the earth. After 150 days,
4 exactly five months from the time the flood began, the boat came to rest on the mountains of Ararat."***
note: the Ark became grounded 5 months from when the flood/rains actually began, not from when the Ark
was first floated.
early low level flash flooding likely occurred before rising waters reached the Ark.
