At a minimum suggest you take course(s) to give you a basic idea of the daymarkers, charts and how to plot a course. If your wife does not want to take complete courses suggest you find a course called skipper saver or some other name which gives basic instructions to woman as to how to get the boat back/ call for help if the skipper is overboard or stricken.
