Hi team,
I hoisted my new North main for the first time yesterday. It seemed too long: by a couple of inches. Still a few wave along the luff slugs (no rope).

I was in a rush and will not be able to actually measure the luff before next weekend
A cunningham can handle it.
But it looks more like a mistake - although I find hard to believe that North Newport would make such an error on this class.

I have a shackle spliced on 5/16 dyneema halyard on the head, that might cost me an inch of luff but there is more than that here.

Any of you have similar experience? with North?

Did you not have North come out and measure?

They told me they did.
I will live through the season with a cunningham. They were responsive and open and told me an easy fix if it needs.
I will top my halyard this week-end and measure everything precisely.
Will also try to reduce as much I can on the top by not attaching directly the halyard but through a loop.

I guess my real question was: do you need to do any halyard trick - like not using a shackle - or less than 5/16 spliced halyard to max you OD main luff?
Cheers,

Just to close that thread. Issue was only mine.
The main (NPC Nordac Radian 7.5) was perfect. Luff length was 37' 9 1/2" that is 2" 1/2 below max class length which is fine for me. (about 1" shorter than your 3Di Jim). 38" is exactly the max I get with my halyard topped out.
After spending more time on this, cleaning up a bit the mast groove, measuring with tack free. it at the ends boils down to this new main being really the first true class legal one I have on this boat.
My prior main was a bit shorter, shorter enough for me to deal with luff tension only with the halyard tension. Not something I can do anymore with this one.

all set. thanks fellows.
