Default North 9.0 WARP with softer masts

Hi All,

I've purchased a second hand 2006 North 9.0 slalom WARP and I have rigged it with a compatible 520 / IMCS 32 mast.

I've noticed this sails is very physical and from recent races I came out really exhausted !

I regularly use North formula and free-race sails with their recommended masts and I valued NS sails for their soft feeling but I feel this sail (9.0) is really hard to drive & control when wind rises.

I wonder if this depends on using a compatible (maybe stiffer) mast than original 520 North (anyway, always IMCS 32).

What do you think if instead of using recommended 520 / IMCS 32 mast I will use a softer 490 mast (or a mix of 520 bottom and 490 top) ??

Thank you in advance for any help.

I recently upgraded my NS F2004's 5.4m to 11.9m (which I loved) to F2006 5m to 11m (which I hated at first). They also felt very physical CW the F2004. After getting some advise from NS racers/speedsteers, it turns out that all sizes need alot more down- haul. I'm now using the "max dot" on the VTS as its "min" set and going about 4cm past the "min" for max, does that make sense? Sails now feel lighter, cams rotate better (but not perfectly) but still feels taught in a good way. If you use a 490 mast, the sail will be very flat & might feel a bit gut-less. CE will move back sooner in gusts as well. I could be wrong, so it might be worth trying if you have a 490. But it does sound like under downhaul is the problem.

Default I agree with Mark

I've recently been rigging my 9.9m 2008 Ram on a stiff 550 Plat mast. Gave me a nice deep profile with medium spacers on the bottom 3 cams. It also allowed me to downhaul to max without flattening out the sail to much. I needed this set up as i was using the sail for FW until my 10m warp was delivered. My 2007 9m Warp rigs fine on the standard 520 plat mast, and does not feel like hard work. I am however having trouble rigging my 2008 10m warp to a satisfactory shape. Cams are not rotating as easily as normal, and it seems very flat. Anyone else having similar trouble with North 08 formula sails?
