Your original goal is to get more kids sailing, Correct?
Those kids are not currently sailing with their parents and not involved in sailing in any way, Correct?

I personally love to work with tools and build things.
From what Phil is saying you will need 100 hours and at least a circular saw, jig saw, router, screw guns, maybe an orbital sander and epoxy or glass supplies and some know how. You will have to have plans for the aluminum or SS parts and have some machining and welding done.
You and I may have all that already, but the people you are trying to attract won't.
People in the USA have their lawns cut, driveways plowed and almost everything else mechanical hired out.
Your potential number of home boat builders that don't currently sail just went way down.

Now if you can get a group of guys at a club to turn out some boats and start a program where the moms can just drop off the kids to sail(mom gets alone time) I think you may have some success.
