As I said before, you can learn tons with a sailing simulator, but there's no seasickness when sailing a simulator.
My first
boating experience was on small beatup
power boats I bought as a teenager 20 years before I started to sail.
Point is learn what you can on the sim, then start getting on the
water experience asap on some type of
small boat
You learn so much faster on a
small boat with lots of sail area because when you pull a "string" something happens and it happens NOW
On a heavy
monohull it can take 45 seconds for an adjustment to affect the boat
