If you would do something like this with a 50/50 chance you don't have the right attitude to go sailng.
Would those who encourage you be prepared to go with you?
I doubt that the boat is more than a coastal cruiser and although they are inexpensive you should probably allow $20,000 to equip it and bring it to standard.
Sixty is not too old, but I suggest you do some sailing first to learn something about it.
While people here would help you, the obvious first step, if this was a genuine aim rather than a pipe dream, would be for you to take the responsibility of researching learning all you can from material easily accessible rather than expecting to be spoonfed.
It may be possible to do what you plan, but irresponsible for someone who knows nothing about it.
I would say your chances are much less than 50% at this stage. While your boat and your life have no more value than you put on them, you also put others at risk if they have to attempt to rescue you. Their families may value their lives higher.
