Good luck!
Have never heard of them having been done for Grampians of any model. By the way, it is customary to use regular case typing when posting to the forum rather than capitals.

Basically, polar charts show boat speed as a function of true wind velocity and angle. If you go to the archives on this site - type in the word "polars", tag "all posts" - you will come up with tons of information. You rarely see racing polars done on boats unless they are from the new hi-tech generation.
Polars ......
If your boat design has had a track record in racing, USSailing (website) will probably have them available .... for a price. If there is any type of owners association for Grampians, go to that organization (or discussion group) and you'll probably find a copy there, maybe even a polar plot that an individual has made ... but you have to ask. ;-)
