Save the looking at actual boats till you are closer to being able to check out. Use the time till then to educate yourself about boats. Start by coming to understand that the seaworthiness of a boat has nothing to do with the material from which the hull
is made, and that at this point in your evolution into a sailor there are many, many more important things for you to consider. Bear in mind that the vast majority of yachts that cross oceans - even as I write - are "frozen snot" (fibreglass) boats. That construction material is, ultimately and for many reasons, the most suitable for a novice's first boat.
Put some effort into coming to understand that it is NOT the boat that takes the crew safely across the ocean. It's the crew, particularly the skipper
, that takes the boat safely across the ocean.
Here is a ref to a site where the basic traits of many, many sailboats are set forth:
Skull around there and do some "compare and contrast" thinking about the divers boats listed there. Come to understand what the numbers all mean.
You are in the UK, you say, so go join a sailing club. Even if you are in Birmingham, join a sailing club! Learn the basics sailing dinghies on the reservoir. Then skive off to the Solent and sign on as crew on a smallish cruising boat. Meanwhile take all the theory courses you can find, including those on meteorology and on engine maintenance
. Learn your radio
And don't fall into the trap of thinking that buying
and operating a boat that can "cross oceans" is anything like buying
a motorcar and blasting it up the M1. It ain't!!
All the best to you.
