Hi, I think this has been mentioned before, but if I want to run my 5.8m 2009 Koncept on an RDM, where do I get the cams? KA?

Are there any other cams that might fit, or are the KA RDM ones special?

The RDM I have is a 430cm Ezzy.

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.

Comments?

My only comment is did you contact the Love Master ?

That's a bit of a root around when you could have the real deal FN, I'm too lazy for that and would have just got the right ones

I guess that's 3 comments

We are actually out of the correct RDM cams at the moment, some on the way from the Factory now. Andrew does have some other RDM cams which he is using on the Moth sails, just not sure how many of those he has either , will check.
I actually have one sitting next to my computer at the moment and will root around and see if i can find a couple more
Your Ezzy solution looks OK to me although the "tongues" that stick back and the hose will put a bit of a lump in the luff sleeve when the batten is rotated and could cause a wear point long term.

I heard he was busy playing with his 'Love Muscle'... The board is what I am talking about.

I emailed him at the time of the original question, and apparently there are no RDM cams in the country and they are expecting the new shipment in in the next week or so.

The other reason that I did this, is that it means I can use the same cams for my NP sails that need RDM cams. The Ezzy cams are very easy to get, so it may come in handy. To adjust the length, all I need to do is cut a different length of electrical conduit.

Another reason... I had them already lying around and were free.

Thanks Martin. I know you said they were on the way, but it was a nice day and I was too sick to go to work, so what else was there to do...

Yeah, the tongues do stick out. I can either cut them off at the point they exit past the batten tip, or I can cover them with a piece of sail cloth. FWIW when I looked at this, there is something else as part of the batten tip that also protrudes through, behind where the tongue sits. I will rig one of the others on an SDM and see if it still shows through.

I was surprised at how well they rotated though and it will be interesting to see how it sails. Hopefully the Ezzy RDMs can give me a mast that will work okay with the KAs and also a few NP V8s.
