Topic: Polar Plot diagram for JJT CO26?

Does anyone know if a polar plot diagram was ever published for the JJT Contessa 26?
If so, I would love to get my hands on a copy.  Thanks.

What is a polar plot diagram?

Yeah! Isn't that for antennas?  Please elaborate for us if you would.  Thanks.

The question is related to VMG (velocity made good) to describe boat speed made relative to the direction of the wind.
VMG/sailing performance for specific boats on various points of sail is sometimes described by way of a polar plot or polar diagram. The information that supports these diagrams is derived from velocity prediction programs (VPP), which take into account the boat's displacement, sail area, and righting moment.  Using a polar diagram for a particular boat, the crew on board is able to gauge the boat speeds that they should be able to attain for best performance for that boat design on every point of sail.

From what I can tell the development of polar plots for various designs seems to be a relatively recent thing. 
Since the CO26 is an older design, I am curious whether a polar diagram has ever been developed for our boats?
