That's a tough situation, I've been there many times in the past. (when the kids were kids)..
I don't know that area, but if you can just fish open water, or anchor up near some structure and relax it will be more pleasant for both of you.
I had my 75 Y.O. father in law out the other day, almost the same senario as you have

At least I put him on some fish so he was happy.....
