So, I need a good way to repair about a 1' by 2' section of boat
cover. Might try iron on patches, if they come that big. Don't feel
like investing another $400 for a new cover now.

Any suggestions?

If it is canvas it will need to be sewn to have any strength. Any
sailmaker or canvas shop should be able to do it in a few minutes.
