As I had a few sets of Ezzy RDM cams lying around from my Infinities and no KA RDM cams (yet), I decided to see if I could try them with the KAs.
I looked for the first time at the cams on the KA's. They look suspiciously like Gaastra cams, and are located by the end of the batten the same way as the Pryde sails, except they are using layers of sailcloth instead of the molded part NP use.
After thinking through various complicated methods to add a spacer to these, I decided I would try a simple bit of plastic between the cam and the batten, and what do you know, it seems to work.
I think I read about using reinforced hose for this on another posting. Are the KA RDM cams similar to the Ezzy ones, in that they have the pigtails out of the cams? These normally fit into a pocket in the Infinities that you vary based on the diameter of the mast.
Surprisingly I got the fit right the first time. Was it luck, or is there a certain amount of tolerance you can get away with?
Anyway, here are some photos, with the first one showing the KA cam, and then the Ezzy one matched to a NP batten molding, and my special spacer.
Do you think these will do the job? I haven't had a chance to sail it yet, but the cams seem to meet the mast fine, you can pop them on okay, and rotation on an Ezzy 460 RDM feels perfect.
