HI All

Sorry if this has been asked before but i have looked through the forum and havent really found anything that addressed my issue.
I hit a problem when rigging the NP RS4 5.8 sail. this is my first cam sail and Im getting stuck rigging it. Im up to the point where ive slipped the mast over the cams and am downhauling it to get the mast to stick out the boom cut out in the sail. Problem is [it feels like] im downhauling the crap out of the sail but the mast doesnt seem to want to pop out the boom cut out and im just worried about snapping my mast while downhauling it. I know the recommended mast is the NP X9 (100%) but ive got a powerex 430 (40%) lying around and i dont intend to be racing so thought it should be ok.
Im just wondering how much downhaul do you need? should i just try downhaul it to spec. or should i try coax it out by attaching the boom while the mast is still inside the luff pocket and try outhaul it out :S

Any suggestions/help would be much appreciated.
again sorry if this has been covered before.

Thanks for the reply guys,

No this isnt Rubby

and yes i have looked at the rs4 guide. I was just after some personal experiences from people who have used this sail to see how much downhaul you guys are using to get the mast exposed through the boom opening, for instance are you downhauling all the way (434cm) or half way or ...?

Cheers

I dont know much about cammed sails but following the directions I got to rig my KA Koncept 6.6m I just downhaul enough to be able to reach in and find the mast & then attach the boom.Its a bit of a pain ( especially as the first time I had to do it Id never fastened a modern boom to the mast either and I had to do it by feel) but then I outhaul it as much as I can & push the cams on & then finish downhauling.I dont know if its different for NP.

much appreciated guys

Mobydisc i will take your recommendation and try downhauling as much as required the second time and see how it goes. thanks

Cheers for that jimbob
Good to know a low carbon mast will take the grunt of the downhaul, i was just afraid id snap my 40% while downhauling the thing
will give it heaps next time round that i try rig it

SBC, I don't want to change what you are doing if it works for you, but I thought the best way to go is the way that they are describing for the RS4 as well. I rig all my 'new' cammed sails this way, Ezzy's, KA's and NP's.

I think you need to downhaul enough to put on the boom, downhaul to the intended setting, and then put on the outhaul. This makes it far easier to put on enough outhaul as the sail is now loose at the clew. You then let off most of the downhaul so that the tension in the sail between the clew and the mast moves the cams away enough to let you easily put them on the mast.

You then pop on the cams, and then downhaul back to where you need to be, and then adjust the outhaul settings.

I remember the bit about the KA's and putting the boom on earlier. I am now trying to remember why, or even if you really need to. I think I might need to start rigging my sails on the grass to remind myself what sailing was like...
