well, I agree you may have bitten off more than you can chew for a first bite, but there is something to just getting out there and doing it too. No harm done, just slow down a bit, both of you should take the classes cause the more sailors you have on the boat the better.
Also, find experienced sailors who don't have a boat currently and get them to come along and sail with ya.
Don't worry, all of us have horror stories when we first started out, but one thing is clear, after even two sails under your belt you will feel much much more confident and have learned a lot. Think of how much you learned these two times out and how much better you'll be next time.
Welcome to the best sport ever!!!
