Yeh as AKA-non recommended, some classes
will help you a lot. Plus you will be able to make all the mistakes
on someone elses boat and not bump, break and scrape your own. Else hire a sailing instructor to come out with you for a couple of days. It will be a good investment on money
saved on gear
you dont break or heads you dont injure. There are lots of stories of people trying to teach themselves then becoming disheartened as a result of constantly damaging their new boat.
But if you are really going to give it a go yourself, the very first thing you do before any sail is "check the weather". In your case, if you are sailing without experience, stick to under 12 knots for a while. At 12 knots you can start to see the little wavelets break. It will be slower sailing, but its good learning weather
. Do not even attempt to go out in 20 knots.
That said, congrats on the new boat. She sure is a pretty little girl and comes with a good reputation.
