I can't say for certain since I'm not in his shoes BUT I think my boat would be more important to me after such a procedure. My wife calls the boat therapy. On a nice day I'll go down and putz about, make a
repair or two, or perhaps just sit in the
cockpit and watch the world go by. It certainly beats sitting around the house and is about the most relaxing thing I can think of.
I don't know how big his boat is, but perhaps after time he might want to downsize to something that he'd be comfortable
single handing. The computer generated voice is also a great idea. Hey if it's good enough for Stephen Hawking. Besides, there aren't that many times I even use my
radio besides calling TowBoat US.
