No mistakes
Fortunately, you will probably not make a mistake with a Catalina, or a Beneteau, although you might, with a Hunter. But, there is a reason that they are the three largest sailboat builders in the world, which is that they all build a good product at a fair price. I can remember a time when I worked as a sailboat instructor for the local Beneteau dealer, lived on and cruised my Hunter, and raced a Catalina. I liked all three. But there ARE differences. Beneteaus are consistently fast hulls and excellent sailers. Even their in-mast-furler Oceanis series, which look like real clunkers, move beautifully. They are a little more money, and a little more finished. I don't think their build is any better, although THEY do! The Catalinas are the most conservative, with fewer models over the years, which is one reason they hold their value. They also seem to sail better than they look, at least to me. The Hunters are easily the most innovative. As others have mentioned, some of the innovations work out superbly, and others are disasters. So, pick carefully when it comes to "bright ideas". There are winners and loosers among them. The frequent model changes hurt resale prices but can lead to a better value in a used boat. I think that Hunters have always had the best standard of the three when it comes to equipment, and the sizing of the same. They do not seem to skimp on this. My personal Hunter is a 1980, which is generally thought of as a more erratic period in Hunter's history. I would agree. Some of the ancient Hunters were built very well, and some were built poorly. Mine (which I have owned for nineteen, mostly happy, years) was a middle-of-the-road build. But, with some modifications and corrections, she has served very well to live aboard, cruise extensively, and even use for serious offshore work. And, I have known people who have circumnavigated in Catalinas, Hunters and Beneteaus. I remember one guy who did it in a Catalina 27. So you "pays your money and takes your choice". One VERY IMPORTANT caveat is that commisioning is crucial. If you are buying new, talk to as many customers of the dealer as you can. See how they put everything together and how they back their work. There are very professional and very un-professional examples, I am afraid. In an older boat, your survey should be able to answer these questions. And, in the end, when you have narrowed the choices, I guess it really DOES come down to the boat that will get you and the mate on the water most frequently. Good luck, and have fun.
