Budget is the the key. If you've got the money there are alot of good used boats out there. Are you going to trailer or slip and storage, winter/ summer. These are questions that need to be addressed. Small cuddys are basically for storage and a porta potty up to 25' and maybe a few overnighters. A good size liveaboard for weekends depends on marina and or other location for the stay plus comfort requirements. As always "bigger is better" but it takes more $$$.
