Hi Guys, hope someone can help , im new to this great sport and am in the process of getting my rig worked out. I have a North Sails 440 Carbon mast , two peice described as a constant curve flexTop mast with a MCS of 2-3 . This does not seem to make much sense to me. However My newish sail is a Neil Pryde 6.4 RX1 and i am having al sorts of trouble fitting the mast to the sail..
its seems to me that the mast is unsuitable for the constant curve type sail, but the MCS of 2-3 dosnt give me much of a place to start
If anyone can shed any light that would be great ..
Hi Mazz,
Welcome aboard!
'Constant Curve' means a bend curve of around 12%. "Flex top" means a bend curve of 16% or so. The mast can't be both! Unfortunately companies like North and Pryde are notorious for putting confusing information on their masts so you'll have to do some digging around.
Pryde usually sit well on a flexy top mast, and so do North sails, so this shouldn't be too bad.
Does the mast say "IMCS 23"? This would be about right for a 440 although 440 is a slightly unusual size (a 430 is usually 21, a 460 is usually 25).
A good page to spend an hour reading is this one:

What does the sail look like when it's rigged? Do you have any photos of it rigged up? What's the problem in fitting the mast to the sail?
Hi thanks for the reply, the mast actually says MCS 2-3 definatly not 23 as thats a number i would expect. Fitting the mast into the sleeve is the problem. The mast will not bend, or bends very little to except the shape curvature of the sail , making it impossible to insert.....
Mazz, When you try to rig mast into Luff pocket, you trying to slide it in with the cams on the mast or off the mast. Think it goes in with cams off, and you set them onto mast after fitting mast all way into sail and applying down haul and out haul, then forcing cams onto mast. http://archive.neilpryde.com/pdf_all/manuals/rx1_tge.pdf
Hope this helps
The thing that helps me, is to keep the cutout for the boom closed, ie the luff sleeve at top and bottom of the cutout touching, until the mast tip is in place.
And it will probably be easier still if the luff pocket is wet, (nothing like a bit of lube)
But you may find that sail won't set optimally on a north mast.
Hi Mazz,
Last year I got back into windsurfing and bought a 6.6 RX2 and matching Neil Pryde mast and boom off ebay. Initially I had a fair bit of trouble trying to rig it.
Mineral1 and and Wet Willy are on the right track.
Hi Guys , hey thanks for all your advice, much Apprieciated. I like the idear of downhauling, and outhauling then setting the cams that might be the trick. Those damn cams were causing such a drama trying to keep attacted to the mast. My old sail was a 5m north sail and bloody easy to rig in comparision.
Will post my success when I get a chance to give it another crack.
And yes I do have a mast extention!!..
Read throught the link you sent me "Mineral1", thanks. It doesnt mention wheather to rig the sail initially with cams on or off, but im thinking Cams off must be the way to go .. thanks again...
