If you have never sailed you may be in for a shock. It's more of a lifestyle change and learning curve. It's a little bit slower......
My view; look for something in the 40-45 foot range within the last 15 yrs. Something that can be dual-handled easily. There are true "blue water" cruising boats out there. You'll need to do your research and spend more. Don't rule out catamarans.
Honestly; i think you can do better than a Hunter 460; especially for ocean work. Just my view.
Some of the sailboats i consider to be at the very top of the list.
Hallberg-Rassy - Sturdy construction, superb craftsmanship and signature seaworthiness
I believe these to be biased to older cruisers.
