Has anyone sailed with the new '08 N.P.'s that have the ultracams in them?

Nearly fell for it, I have and they are so...................

Yep, I have 2 sails with Ultracams. They do rotate really smoothly, certainly much smoother then my sail with normal cams.

I dont think they offer any advantage over the oldstyle cams, but they are definately smoother. They dont rotate with a bang, they allow the batten to rotate slower and with less fuss.

Yes, but Brucie is the Master Baiter!

Thanks JayBee for the intelligent response. So you don't find that they hesitate before rotating and then rotate with a jarring snap like many other camber inducers?

Nope, they to rotate quite differently. I find that my battens flip, but do not drag the cam fully around with them. (A bit like the bottom cam in the RS5 which has to be kicked around after the rig flip.)

Then the pressure in the sail makes the cams complete the rotation as you sheet in. Very smooth and controlled.

Of course that is on the V8, it might be a little different on the RS Racing where there are more cams in the sleeve.

I have a RSR 8.4/6.7 & they rotate completely every time.

The feeling is very similar to a raf sail going around.

Infact with the 8.4 in very light wind it still rotates every time.

OK, if we are going to be serious I have a 7.6 RS Racing and it rotates quite easily. If you are fully powered they go around smooth. If you are tacking or just changing sides sometimes they need another pump to complete the rotation.
On the RS Slalom MkII 6.7 they go around like they are not even there, smoothest rotating cammed sail Ive ever used.

Great responses!!! Thanks for the answers. A cambered sail that feels like a R.A.F.? That's terrific.

ka43, i got a cheap 300$ rsr from a semi-pro less than 10x used 7.2 and downhauled it to the last panel above the boom to a flutter leech..still it doesn't rotate nicely-battens first then the cams. i use the x7 instead of the x9 would this be the problem or more downhaul

To be honest JP I wouldnt know. First season using NP stuff so Im not up with anything other than X9 and new sails.
The man to ask is Sam Parker at info@windsurfnsnow.com.au
He's been using NP stuff since JC was a lad.
Hope this helps.
