Catalina 27 or 30
It depends also on how you plan to sail. If you plan to solo sail, a 27 with a tiller is super. I used to sail all over by myself with cat, and having a tiller and an autotiller was the way to go.
Lines lead back to the cockpit not to the wheel. And it is just easier to get around the boat solo sailing with a tiller.
Having said that, if I planned to sail with a mate or a crew all the time, or with a family, the wheel would be preferable and the room in a 30 is much, much more.
But a 27 is quite roomy too. Depends what you want and what your personal preferences are.
Where will you be sailing it?
