I am pretty good at stretching dollars; I also know that projects always cost more than planned.  Accordingly, the following amounts are broad estimates:

Boat Hull and trailer - $30,000 to $40,000
I will either have a stripped down modified boat hull manufactured or I will purchase a used boat.  I will begin with a boat hull that has a known good wakeboard and surf wake.

Initial test flow channel, hardware and hydraulics - $30,000
This initial flow channel will have many adjustable components to determine angles and volumes for best function.
 
Demo flow channel, hardware and hydraulics - $20,000
This flow channel will be designed and built based upon the test results.  With this set up, the hull will ready for demonstrating.

If I personally get paid, it will be for my labor at the rate of $12.00 per hour.
