Racers are the most obsessive of all sailors.
When I used to race, I would find myself on the freeway trying to think of a way to put that Tercel in the other lane into my wind shadow. What I learned over the years is that driving skills and sailing skills, really do not have that much in common. But when you love sailing, you try to bring it into every other aspect of your life. However, if he installs lifelines around the shower and wears a harness while bathing, perhaps professional help is required. When it comes to sailing, you've got to love it to do it, but you've got to relax to enjoy it.
