There's a list of blue water boats here on sailnet here
We spoke to an older cruising couple who cruised in a Fraser 30 back in the 70's. Before they left, they used to go out and sail when the wind was blowing hard and everyone else was staying in. They thought they were pretty well prepared. When they left Vancouver B.C. for San Francisco, they did it in one haul. She was sea sick for days. He was afraid that her feet were going to rot off, because she didn't take her boots off the entire trip. When they came in to San Francisco, the harbormaster asked where they were going next. She told him "I don't know where he's going, but I'm going home." She was ready to give it up, but changed her mind after a hot shower and some rest. They continued cruising for several years after that.
