Just convinced myself to semi retire and I have always wanted to sail.

I've owned power up to 38' and know navigation, docking (with power)
etc. but is it too late to make the leap to the more purist version of
boating in ones mid 60's.

constructive comments are welcome as to size, type or make and big
enought to cruise in fresh water (for the time being)

Is it an impossible learning curve unless you start at 6 years old.
