That boat, like most under-30 foot express cruisers, is really made for protected and semi-protected water (like a bay) use. Light weight, shallow 'v' hull. Not to say you can't take it offshore in good weather, but watch very, very carefully and be prepared to run for cover long before conditions turn nasty. Catalina is what, 20 or so miles off the coast? 10 miles can be a long run to hit landfall if the ocean churns up.
I'd want to upgrade my bilge pumping capacity and make darned sure I had a DSC-equipped VHF tied to a GPS, or a new VHF with built-in GPS (I bought a Standard Horizon for under $200- it's cool).
Have you considered a walkaround cuddy, instead? Those are built on the same hull as a given manufacturer's CC models. Much better suited to open water, tho you'd have to go bigger to get the same cabin space.
