Proving the hull concept ...
Building a 1:5 scale model to test on the water.
Hopefully, it will give a useful indication of the performance of the hull design.
Test Priorities :
Power :
1) Record Speed under Power ( have achieved this to a degree with a Contour GPS Video Camera.This Page)
2) Record the amount of power used to reach the speeds ( discussion here at BoatForums )
Sailing :
a) Record sailing speeds ( Contour GPS camera )
b) Record Heel angles
c) Record Wind speed
d) Record wind direction
e) Record Rudder angle
f) Record Sail Sheeting Angle
While the Contour Camera does the Speed recording quite well, it may be worth adding a second GPS device to stream to the data Logger automatically, for ease of analysis.
It would be more efficient to hire some experienced Developers familiar with the Arduino Board, who had data logging experience, than spend a lot of time in trial and error on my own. I have tried to summarize a logical apporach to the data system development here.

December 2011 - The two side panels were cut from a sheet of Fibreglass. The sheet of fibreglass was a layer or 6oz cloth, and light chopped mat laid on a smooth surface. I used Vinyl-ester resin (cheaper) to make the flat sheets, but epoxy to glue the panels together. The stage below shows gluing strips of marine play along the bottom chine, to create the 'planing-step' for the hull.
