In 69:11 it is to them,Allah is speaking from a different perspective here,in this verse he I see speaking to Nuh and his people and saying "You" as in Nuh,etc,etc and only Egypt,no there is no mention of Egypt it was most probably in Iraq-Syria where the flood happened.
And on 69:12 it tells us to get a lesson out of Noah PBUH and reflect on his life.
36:41,Yes i do think this is about ships only. If it was Nuh A.S there would have been Hadith narrations behind it saying so,but none of that is to be found,so I think that this verse is just telling us how our ancestors immigrated.
[007:059] We sent Noah to his people. He said: "O my people! worship God! ye have no other god but Him. I fear for you the punishment of a dreadful day!
[003:137] Many were the Ways of Life that have passed away before you: travel through the earth, and see what was the end of those who rejected Truth.
