As emKay relates, you've got yourself one of the more desirable boats in that size range. They're very popular for racing particularly on the west coast.
The previous advise is correct and you'll find that you may have water rolling right into the cockpit and still not close to going over. Keep your
hatch closed! You'll have to play around and see what your best combination of sails are for conditions. My Cal 21' benefits from a reef in the main while stilling flying the genoa. You'll probably find that she moves best at around 15-20 degrees heel. You're going to have a lot of fun finding out. Sail it like you stole it!
