I changed the mast on my N6.0 orig to an NA mast(ie-double diamond wires). I raced this fall in a local regatta and they insisted on rating me as a 6.0 NA. I do not carry the sail area of the NA(self tacking jib and 3% increase of main sail when changed to sq top). Does the addition of the extra diamond wire make my 6.o orig an NA? Personally, I wouldnt think it would.
Along this same line, I havnt been able to find a max sq ft for the main sail of an NA. I dont sail one design obviously. Always Portsmouth. If they insist on rating me as an NA, Couldnt I have a low wind monster main made to include the SF lost in the jib and Orig Main? Im getting killed in the lites.

I didn't realize there was an NA mast, I always thought it was afterthought because they were breaking too many of the original single wire mast.

In looking over DP-N the only mast modification I can see is for "MT = For taller mast than standard" which I don't think is your case.

But, do you have a square top, bridal foil, etc.....? If so then even I may be a little inclined to rate you at 63.9

In answer to your question about a low wind monster they way I read the rules is they take each modification separately, and I don't see a correcting factor for carrying a smaller jib. In light winds you may want to go back to the old style.

Yes, I do have the bridal foil, sq top main. But when I had the new main made, I stayed with the size of the orig main that it came with. Maybe I need to have a main made that fits within the measurement parameters of the 6.0 NA for low wind days. I dont think its worth changing the jib over, lotta work.
Do you or does anyone else out there know the sf of the NA main?
Thanks for the input VR.
Merry Christmas.

Contact Skip Elliot at E/P sails, he did all the designs for the 6.0. As for the mast, it is a modified rig regardless of change in sail size. Since you have a mast that can take it, get a new main made. E/P makes a bad a$$ sq top for the 6.0 NA.

There is SE a sq top on beachcats but I don't know if its maxed out or not. Seems to have a pretty small sq top also. Maybe Ill contact SE and see if I can get some info on it from them.

I looked at that main. It's not a NA. Something fishy about it and I'd bet it was made for a boat that simply had a 6.0 mast. For that price, I'd go to Skip or Chip Buck at Whirlwind. If you go to Chip, be specific on the amount of curve you want in the luff (around 1.5 inches) and let him do one for you.

Yea, I had chip @ Whirlwind do my current main, he does a beautiful job, and his pricing can't be beat. I think that I could go a lot bigger though.
I sent Skip an email re the one on beachcats, Ill see what he says about it.
Im going to try to get Matt on the 6.0 sometime in January,. Its been a while since he's been on the water. Im going to have him skipper so I can learn a bit more about the spin. I also got him hooked up to race the Birthday regatta and Leukemia Cup at Pleasant on an R-33.

I think the 6.0 is like the 5.8 in that only Skip Elliot knows what the "official" size of the sails is.

The size will be published in old Nacra marketing material, but in my experience the size listed is quite a bit larger than the sails Skip makes. I guess that the sales brochures include the mast area.

I may be wrong, but I don't think the boat came from the factory with a square top main even with the NA configuration.

The North American configuration was the addition of the foil to accommodate the large jib sail for off the wind sailing.

IMPO if you don't want to be "dinged" for being an NA then take the foil off.

The Factory specified Nacra 6.0 and 6.0NA sails were pin-head sails. Any square top sails were custom built.

All the 6.0's came with a foil too. The early ones were round.

Nope ,the original had a pigtailed forestay like the N-20, the NA had the foil.

I didn't know that. Roy Seaman told me otherwise when I was looking at one of the first ones which was a lengthened 5.8. It was also 9'3" wide. Kind of strange.
I've seen three "originals" with the round bar spreader/foil on the west coast.

They probably added the round bar after the NA was released to be able to get the larger jib plan.Like all the mess added to the n-20 in different forms.

Nah! This was another one of Roy's Toys! This was a true Franken Boat made form parts that were lying around Roy's yard.

Was an awesome boat though.

I guess I better suck it up and run as an NA then. It wont be long till i get the itch to upgrade to an f-18 or a N20. Till then I'll have to learn to sail it faster. I guess that aint a bad thing.
