A project
It doesn't take much to make a boat "liveable" for weekending. With a 22 footer, you're really talking about camping out anyway. That being said, it sounds like you would have a considerable amount of work to do to make this boat a real weekender. A new portapotti (a good one that is suitable for use by three people for a few days) will cost you about $120. I can't tell from your post if the boat has a water system (sink, plumbing) and is just missing the water storage tank, or if it is totally without running water. Either way, this is a much bigger project than installing a portapotti. You might want to consider if it is worth it. I know some people who just bring jugs of water aboard. IMHO, the biggest (i.e., most expensive) issue you have in making this boat into a weekender is the lack of cushions. You will be shocked to find out how much they will cost you. I would not be surprised if you are quoted prices in the neighborhood of $1500-$2000 for new cushions. That is a pretty hefty chunk of change to plunk down on a $3700 boat. I rejected purchasing a really nice older Oday with bright orange vinyl cushions for that very reason. As far as sailing qualities go, I like the Oday 22, especially the ones with a centerboard. However, if you are really looking to stay aboard and want a 22 footer, I would go with the Catalina 22 over the Oday. The Catalina has a few big advantages over the Oday: Catalina is still in business and still makes and supports the boat; you can get parts cheaply and easily. Second, the Catalina has the pop-top cabin, which makes a BIG difference on a 22 foot boat when you are staying overnight. Third, there will be a lot of Catalina 22's available to choose from no matter where you are (it is the most popular production sailboat ever by far), and it will hold its value. However, I prefer my boat, the Oday 23 to either. It has the keel/centerboard combo which I think is superior to the Catalina's swing keel, and it has a separate cabin forward, giving privacy to anyone who needs to use the head. Good luck.
