The point being, you don't have hands on experience.
We can only write about ours, and you can only read. You still don't have any experience of your own even if we write essays for you. . Books often have much more structure and are better for skimming for general information. Web searches....For example, you said you didn't know what a cockpit was. A 15 second google search brings you this:
google... parts of a sailboat, and look at images:
parts of a sailboat - Google Search
I'm guessing you're not a native english speaker. That's fine... you can do the same googling your own language google site. For example:
google.co.jp.... ヨットの部品名称 .... etc.... (no, I don't think you're Japanese, but you get the point.)
After completing your 10-15 second web search and doing some reading, now that you know the parts of a boat, you can read any number of threads here or other sailing websites and be able to follow the basic conversation. Understanding the conversation will happen as you experience things on your own.
"There is a lot of difference between reading a books and having "hands on" experience. "
Indeed, and what's most important is for you to develop your experience, not only read about ours. It will be much more useful to you asking questions about what you're actually experiencing than about hypotheticals.
Take some lessons. Sail monohull dingies and small catamarans first, then you'll understand the basic forces that make each capsize, and the relative difficulty righting them.
"Just asking experienced sailors if would be possible to recover from unexpected disaster."
Most "unexpected disasters" have to do with a piece of broken hardware and /or particular weather conditions. What's safe for a monohull might be very dangerous for a multi. Most boats sink at the dock or at their mooring through neglected maintenance and less frequently, just bad luck.
"Yes, all boats sink, just one goes down faster that another."
... and being monohull vs. multi doesn't matter. The point being there are many ways to sink a boat. If you hit a whale, it doesn't care if you're a mono or multihull, and a collision can be catastrophic to both types of boat. But more problematic is that you don't have any idea of what conditions are dangerous for either type of boat, nor the physics involved in righting moment, etc...
(Keel boats... in heavy weather, you close the hatches, including the companionway hatch. If you're knocked down, or roll, the boat won't likely fill up with enough water to sink, and the boat will right itself. You might not have a rig left standing, but the boat won't sink. If you flip a 30' catamaran or trimaran, you won't be able to right the boat. It won't sink, but you're pretty much screwed.)
