Bill: Jrowan is right that you should not jump at the first one you see unless you're the luckiest sailor on earth and you stumble on a real beauty right out of the gate. I looked at probably 15 C30's from San Diego to Ventura. Most looked great on paper and the seller or brokers description made them "must see boats", but when I actually saw the boat the description and the boat didn't match. One in particular was located in Ventura, which was a long drive for me, and so filthy it needed to be cleaned with a fire hose. Another one, which a young guy had lived on, was painted BLACK inside. You need to look at each boat with a critical eye and don't be fooled by cosmetics. In other words, just because it has 'lipstick" doesn't make it a good buy. Here's some high ticket replacement items - engine, sails, rigging just to name the most important ones.
Don't believe most brokers. When I decide to sell my boat I started out with a broker because I thought he'd have a large customer base, which he didn't. He said he did but he didn't. He didn't know crap about sail boats and asked me to help him with the sales presentation!! When he said that I thought why do I need this guy, who's getting a commission, and I sold it on my own.
