I know a true sailor who went from larger 30'-40' sailboats to a Potter 19' (maybe 17) and hated it. It's not for everyone, especially if you want some excitement.
Honestly you probably won't go out sailing in conditions "un safe" for a centerboard boat, plus towing it and pulling it around the dock with dock lines
and keeping the bottom clean and righting (which would probably never need to happen) are all better with a centerboard boat. It's not like the sailboat just flops over, many are designed to point into the wind if the keel busts out of the water, rather than capsizing.
If you are serious about this, and not just asking another broad question, because you are in southern california and close to Long Beach, newport, Dana Point, Marina Del Rey, then I'd say it a Catalina Capri 14.2 or Coronado 15 (less money) or a Catalina 16.5 (a lot more money) or a Hobie 18 like you brought up in your other thread, or a Flying Scot (19 foot, huge cockpit, can be raced, can be comfortable sailed)
Just go buy something and start sailing.
