This is soooo cool. It's fun to read about someone that's starting out. I also started sailing in dingeys as an adult. They are great fun to sail, and you will learn more aout sailing starting out that way as they also are a bit less forgiving.
I heartily agree with the post about learning how to dump the boat and get her back up. In the children's US Sailing class in Newport Beach (CA), they wait until the later classes to teach this to the junior sailors. Seems that it becomes more fun for the jumior campers to capsze, get wet and right the boat than to actually sail. The upside is that once the kids performed this maneuver a few times, they lose all fear of a capsize, and sailing became a lot more fun.
I have gone through US Sailing classes and ASA classes, and they all are really good in learning the fundamentals.
Have fun, and keep posting.
