You can just about see what people do on this picture here of a phantom (think its Jimbo's boat he may be able to find a bigger version of the pic)


Having just had a carbon mast repaired i needed to cut a hole for a terminal back plate to rivet on to it. I've spoken to two riggers (one is one of the biggest in the uk) and they both gave a quizzical look when i asked for carbon rivets. What are they? they asked, we just use standard rivets.
You need to make sure that there is plenty of duralac all over anything metal to stop electrolysis. Which happens on any two metals.
Cheers you

I guess the first question is what's going on with the halyard. We can be confident that the standard system is potentially adequate, because everyone else uses it.
Next time you sail take an indelible marker pen and mark the halyard at the cleat when raised. If the halyard is slipping then most likely your cleat is worn and needs replacing. If the halyard is not slipping but stretching then different rope or technique would make sense.

I would ask the RS600 yahoo group, or do a search within it for pre-tensioning.

Neptune might be able to help  

You'll need to spend good money on the halyard and LDC have tried and tested the best for each application on their boats, so it would be a tad silly to go elsewhere unless you're planing on experimenting.  

Also you need to check you've not got too much forestay tension on, as I found this caused all sorts of undesirable rig characteristics when I used to 'whack it on' as I knew no better.

The problem is, once the cunningham's on it's nearly impossible to pull it any further up. Regarding adding another cleat, how could I do that? It's a carbon mast, so I'd be a bit nervous about riveting or screwing, and I can't think of what else to do with it.

Looking through the class rules, no mention of halyard locks is made so I don't think they're class legal.

also you could splice a bit of rope inside of the halyard to fatten it up where it goes through the cleat

IF i were you i would add another small cam cleat just below the existing one so you actually have two cleats on the mast for the halyard to run through.  I would also replace the halyard and as Tom says above raise the sail and crank a bucket of cunno on to really lock it off before sailing, if it drops do the same process again to tafe out the slop.
