My peronal opinion about a comfortable sailing boat ( I guess that's what you're wanting too ).
It HAS to have a few goodies that are essential for easy sailing and living on board. Be that for a weekend a month or the rest of my life.
2) AC Genarator.
3) Air conditioning
4) Enough space to store anything and everything that makes live sweet(er).
5) Lot's of tankage both water and fuel
6) More than enough battery
power for all the toys one "needs" in todays world.
The list could go on but if we consider just the above then there's no way one could reasonably fit all this into a boat that's less than 45 feet AT LEAST. Again that's my personal way of being comfortable on a boat.
In fact, I ended up with a 49 footer.
I think I'm a rather experienced sailor but the first days on the new-to-me boat were...well let's say frustrating. I was feared if I was able to handle that big of a boat. Well, let me say just this, now that we've learned that one can't do basically anything on that size boat with muscle power with all the goodies we have on board it's easier to handle the 49 feet than it was with our previous 37 footer.
I'm not trying to say that handling a big boat is for beginners but once one get's used to it I find it actually to be easier to handle a big boat than a smaller one. It's nothing that a beginner can't learn in a relatively short time.
Since this is going to be your first boat, rather than buying
new I'd buy "almost new". Six years old max or eventually less than that. After six years most boats have lost
about half of their initail value. Should it turn out that it's not the right boat for you, you won't loose that much money should you want to sell it.
Here in Europe
you can buy a five-six years old boat for 140-200K Euro in the 50 foot range. I'd start the dream a little slower and then see how it goes.
