If your wife wants to do it, go for it, it will be fun. Don't go to the Norfolk side though. What I would do is find somewhere to launch in Portsmouth and tool around the boats off Hospital Point. There are so many water cops out that no boats will be travelling above idle without getting arrested. If you want to do the Norfolk side, you will have to stay on that side, the cops will not let you cross the river. Bring some cold beverages and join in the fun!
