We know that Noah and his family, along with the animals, were in the ark for over a year, but how long did the ark itself actually float on the water?
Genesis 7.11 says that the fountains of the great deep were broken up and the rain began to descend, “In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month…”
However, it would take some time before the earth started to flood enough to reach the ark and then for the water to be deep enough to lift the ark, and so Genesis 7.17 says,
“Now the flood was on the earth forty days. The waters increased and lifted up the ark, and it rose high above the earth” (Genesis 7.17).
That sounds like it was forty days before the ark began to float.
At a certain point, the Lord made the waters start to recede, and finally the Bible says,
“Then the ark rested in the seventh month, the seventeenth day of the month, on the mountains of Ararat” (Genesis 8.4).
So then, from the beginning of the Flood in the second month, the seventeenth day of the month to the time the ark rested in the seventh month, the seventeenth day of the month, we have five months, but the ark did not begin to float until after forty days, which would mean the ark floated 110 days, or just over three and a half months.
