Novice Sailors buying boat
This not a question with one right answer. Much of the answer depends on what your goals are. There are people who care about learning to sail really well and others who only care to learn to sail well enough to get out of the dock and get back again.
Depending on the specific 36 footer you may be able to learn to sail well enough to get out of the dock and get back again but the learning curve will be much more steep. And by the same token there are a lot of 1970''s era 36 footers that you could never learn to sail on.
If you really care to learn how to sail well, you would be much better off buying a reponsive, 23 to 28 foot fin keel, spade rudder sloop of some easy resold brand.
It might help us to answer your question if you mentioned the make and model that you are considering.
