What type of boat should I buy?

Can someone recommend me a boat that can do that?

I was thinking of buying a boat that's between 30ft - 50ft, but if I need a bigger boat then please let me know. I would like the boat to be able to travel in ALL weather, and water conditions as well.

I would like to know if Yachts are easier to operate than sail boats, or sail boats are easier to operate than yachts?

Are sail boats the least expensive to own, and operate, or are Yachts the least expensive to own, and operate?

I appreciate any advice you can give me.
