I have not found much information either. Looking at descriptions and photos of Cal 22's that are for sale is the best info I have found so far concerning rigging and equipment. Most of the post in here are older...not sure if the others are still watching this forum.
Here are a couple of sites with some basic info that may be helpful. The first one has a diagram and some basic info. You will have to add the logical beggining of the url to my link....apparently users on this forum can not post links until they have posted 10 time in the forum.
This one makes sails and has the sail plan for Cal 22.
There is a Cal site in Canada too that has a lot of Cal information but very little Cal 22 info.
