Another vote for a Scot (we owned #4188). Setting the mast alone will be a chore for you but it can be done. They have (or had) a promo video showing a small girl setting the mast using the trailer winch.
It's a little bit wet in a chop but never harried or overly disturbed by them.
Slightly smaller and still a nice sailor is the Precision 15. Not as robust as the Scot, but not as pricey, either. About half the $.
