We have a 2008 38 that we bought new as a dealer demo in 2009. We moved up from a Catalina 34.
Very happy with the boat. We sail primarily Lake Michigan and the boat has proven to be a good solid platform that has done well in a range of conditions. It's not a tender boat.
You should check the model specific section of this site as there are a few owner reviews on the boat there.

It does have a tendency to sail on anchor but from the posts on that topic I don't think it's unique to this model. Lots of posts on quite a few different boats that experience anchor sailing. I do have an anchor riding sail that helps greatly. Others have posted on other techniques they've used to slow the sailing down. Haven't used a morning with this boat so I can't offer you much on that.
It's a very comfortable boat accommodation wise. We lived on ours for an extended period the last couple of summers. In 2016 our house sold in 3 days and the new place wasn't ready for a while so we lived on the boat for 2 months and we did just fine.
Refrigeration - there are a couple of configurations here. I think standard is a front opening apartment like refrigerator that runs on 12 volt. I say apartment like just to give you a sense of the size, it is made for marine use. An option on this model was for a separate small freezer that is built into the cupboard area just aft of the stove. It's made by same manufacturer as refrigerator and also runs on 12 volt. We can run both refrigerator and freezer on 2 4D house batteries and have had no difficulty getting through 24 hours and still have capacity left. There is a separate engine starting battery. This configuration would not really be suitable as an "ice box" because both are front opening and the melting ice is going to leak out the doors. It's not like they typical top opening ice box.
We do have the optional 40 horse Yanmar and I can highly recommend that. The boat fully loaded is going to push 20,000 pounds and this engine will easily get hull speed even in a head wind. We had one experience leaving a channel headed out into the lake and it was really rolling up. Lots of surge and easily 3 to 4 foot waves inside the piers. And we were somewhat headed into the wind. The boat ahead of us was having trouble making headway into this and was beginning to look like they might be in trouble since making a U turn in that was dicey. We just powered up and slammed through it. Once we got out and were able to change direction for our course reefed sail began pulling and we had a fabulous ride. I can't imagine doing that with the smaller standard engine.
There is a lot more I can tell you but why don't you look at the owner review section, see what else you might want to know and then repost or drop me a private message.
Happy to try to help you.
