Sorry, but I'm 100% man and I say "your over-thinking it"
You have never said "he's stupid" so I'll assume he is not. IF he needs to use the radio......he'll figure it out.
Does he really need to read the chart ???? Really ? he'll figure it out, if needed.
Do you think you are an enabler.........I do.
YOU make him sound stupid, and I bet he's not......
Both He and I sail to relax, and a host of other reasons. Our reasons don't have to be the same as your reasons........leave "OUR" reasons alone and we'll leave your reasons alone.
P.s. My wife/life partner just read this and after she stopped laughing.......she said you need a different hobby. She completely agreed with me. Her words.....not mine.
Best of luck....
