Hats off to you Susan. I wish I could get my daughters as interested in sailing as you are.
Since you've been out of the sailing scene for a while my suggestion would be to start smaller and use this smaller boat as an assessment tool for your final choice.
I've owned a Morgan 30//2 since 1979 and like it but if I could rewind I should have bought a Catalina. A Catalina 30 would have been a good choice for a couple of reasons.
1. There's a lot of them around so picking up a used one would be easy.
2. They still are very popular and the company is still in business, getting replacement parts should be reasonable.
3. THey are good sailing boat and with the right equipment decent racers. Our local across Lake Michigan race (Queen's Cup
www.ssyc.org) was won some years ago by a Catalina 30 (Rag Doll). I believe that the shortest boat to ever win...most of the winners have been 40'+ in length.
4. With a lot of them around there are a lot of information sources avaiable via the owners and you know all sailors are helpful.
5. Because they are popular, resale is easier.
If I had to pick one for you to start with I would recommend a 27' or 30' Catalina.
