Re: A mistress?
The Admiral and I have been married 40 years, I know there's an issue when she introduces me as her "first" husband, like there's a #2 on deck if I don't straighten up.
The sailing's more fun than the working on it part, if it's your first boat and you really like the "sport", it's probably not gonna be your last boat. If she really likes sailing she may get "Just a little bigger boat fever" before you do.
