Obsession and over-confidence

Any new venture requires an element of obsession to succeed.
So after going to the Hobart Wooden Boat festival I've become obsessed with building a boat.

With growing over confidence the process went something like this:

1. First Mate saw the CLC ply kit boats at the festival and said "honey pie can make that".
2. I researched all the kits from various suppliers
3. I researched all the online stock plans
4. I found free boat design software to play with
5. I knocked up a design that I think is great but of course have no idea what I'm talking about.

So now what?
