Jake,
What about dagger boards and rudders, as well as cross bar and hot stick?
I think you also need to add diamonds to the mast (I'm not sure it comes with spreaders either) - this is typically rod rigging.
And then you want to make a few bucks out of it at the end of the day...
I am not convinced the market is big enough to drive the costs down significantly, but it would be great to be proven wrong.
