I have sailed an R29 in Puget Sound for years. I enjoy the boat, since it was dirt cheap and does well in light air. It has an encapsulated keel, and has no keel bolts.
Before buying one tough, I would lie down in the bunks to make sure you are comfortable. I sleep in the quarter berth, and at 6' don't feel like I have much extra length.
I bought a trailer for mine on Craigslist. One nice thing about an R29 or a C29 is that you can easily put it on a trailer, and pull it with a modern half ton pickup. That would be harder with a Catalina 30.
Of course, if you need the space, get the bigger boat.
