I'm sure you will invoke a lively discussion about your focus on traditional full-keelers. I'll say two quick things, and make a biased suggestion:
#1. I applaud you on your choice. There are many excellent "traditional" boats (whatever that means) to be had which are very good sailboats and excellent cruisers. These boats are, as a general rule, solid, well designed, and beautiful. If they make your heart beat a little faster, then you have an excellent eye. Get one.
#2. There is absolutely nothing wrong with many modern designed boats. There are many "modern" boats (whatever that means) that are excellent cruisers. Most are superior sailors (although I really should be defining these terms). Until you've had some experience with a number of boats, I recommend NOT locking into one design concept.
#3. Look for a Rafiki-37. I only say this b/c it is the best boat ever built for a short-handed cruiser, and that's my completely biased opinion
Seriously, there are tons of boats to consider. Here's a list of Cruising World's top 40 cruising boats as picked by contributors: People?s Choice of Best Cruising Sailboats | Cruising World
(Rafiki didn't even make it
). Another site has pretty pictures to accompany their list: Sailboat Reviews of Offshore Cruising Yachts : Bluewaterboats.org
(again, no Rafiki ... how can this be
Ask 12 online cruisers about anything and you'll get at least 23 opinions. I'd strongly suggest getting some real experience before making any firm decisions about design.
... and then buy a Rafiki-37 if you can find one
