We (me, hubby, small dog, and cat) are super comfortable on our 32' Downeaster (sailboat). She's beamy, full-keeled and roomy enough for us to not feel like we're sacrificing anything to live on her. We lived previously on our 27' catalina and it was much too small for us (though we're both tall, so having no headroom was one of our major concerns, some people fit just fine on smaller boats).

, please do! Even though you're on the other coast perhaps you can ask about what boats people have, etc. We looked and looked and looked, up and down the east coast -- when we finally found the one we liked it happened to be our town. Figures. Best of luck! The irwin 37's are super comfy (spacious) but not always ruggedly built for long-term cruising. Do you plan to leave the harbor or mostly just have a floating condo?
