>>1720913You start out green and want to sail the open sea in a 1seater,
I'm not some naggy safety bitch but the chances for disaster are quiet high there.
Not to be rhetoric but sailing vessels convert tons of energy and even if you have the basic knowledge, you might get overwhelmed with... like something coming loose, too much spray water in the bilge, surprisingly heavy sea, traffic, gusts or a combination of things.
I'd try to find my way on a 2seater first, get some hours and get someone to show me the ropes, you don't only get to know how to not wipe yourself out with the boom, you'll also get some knowledge about local conditions, make connections in the scene and find out if you really want to make the expense to get your own boat. And after 20 hours I'd ask that guy what he thinks you should get and maybe he can even hook you up or come with you to check what you want to buy.
...or start in a dinghy and a secluded environment like a lake or a river. Even 4 meter boats have watertight areas and you can always pack a tent, something like my 3.3 meter Europe can land absolutely anywhere. Where I live that's a 800-2000€ completely fitted boat with a fair amount of structural integrity left.
They are unsinkable and if I capsize, I can righten it on my own within 10 seconds.
While the upkeep, transport and storage for my boat are virtually free, that all explodes when you have something like a 6-7 meter small yacht.
I get what you are after but I'd definitely start out small or with somebody else, there's no obligation for a set number of hours / you can sell that dinghy the second you think you're ready. You can do that with a dinghy because a dinghy isn't a commitment, a yacht is one.
But that's also your advantage because owners get to sit on them. Be it that they loose interest and it's taking up their driveway, they can't afford upkeep or whatever. Yachts are liabilities and there's tons of old yachts that don't sell. You just need to find them.
