Since I’ve had a lot of hits to my blog from google searching for things along the lines of "J/109 polar diagram" and "X-332 polar diagram" I’ve repurposed a bit of the Regatta Manager to produce a polar diagrams for all the major one design classes with the option to generate one from an IRC rating.
It produces polar diagrams for the following classes:
|Dragon||Sonar||707||Flying 15||RS Elite|
|Sigma 33||Sunsail 37||Contessa 32|
Shout if anyone wants any more defaults added, I’ll post a link over the weekend.
