Congrats! Post some pics when you get a chance!
Here are some pics. https://picasaweb.google.com/vrhacks/C27
Catalina's are great production boats. There are so many of them, that owner's groups, tech and parts support abound. You'll always be able to get help or information for your boat.
I kind of wish that you had been able to score a C-30 to live on. For a short, single woman, it would be positively palatial. It's amazing what only 3 extra feet in LOA gets you- it's also 2 feet wider! It equates to a lot of square footage. But, I'm sure that the C27 will work out ok.
I sincerely hope that you will actually go sailing, and not become a "Condo-Commander" that grows a reef on the bottom of your boat.
Maybe go for a c30 next year. After I've learned to sail. :-)
