U-Boats
Yes, that is right.
I believe the correct terminology to describe such a group would a, "flock".

Yes. We say A flock of birds roosted in the branches of the trees.
The place where penguins breed on land is known as a Colony. Otherwise, there is no specific name other than a group of penguins.
It really doesn't say how the flock adapted to Iggy's blindness, but i believe that it did take them a while to get used to the fact that Iggy would never be able to see again, but the skills that Iggy gets in result of him being blind it helps the flock while they're on the run.
You will say, I have a herd of cows and a flock or brood of chickens.
The correct term for a group of deer is a herd of deer, flock is generally applied to sheep and birds.
They were simply commercial sailing ships of the time. They didn't have particular colors. Ships were wooden back then, so I would say brown.
