Looking for a book I read in elementary school in the mid 1970s.

Here’s what I can recall about it:

It was a modern updating about a “Noah’s Ark.” Not religious undertones, more of a (early) conservationist perspective about animals. About a man who as a way of saving animals collects animals. (I can picture him faintly, brownish hair with glasses.)

It was a picture book (although not simplistic pictures). For example, the schematic on the boat itself was detailed.

The main character build a modern boat (think a big cruise ship) to house the animals. And thereby “saves” a collection of species.

I know it’s not much. I’ve often recalled the book (I used to check it out continuously).

Let me know if you need any clarifications or if I can answer more questions.
