jib drama , need help with dimensions

[gabi]

 
well...my new jib i ordered came in the mail last week,
it turned out to be too big, around 140 % vs. 110 % like it was advertised

no prob. the maker offered to change it for a smaller one, and here is what he's proposing for dimensions ;paste form his email

"Luff = 12.80' (same)
Leech = 10.55'
Foot = 6.05'
LP = 4.95'

This jib is designed to sheet to the same place as the larger headsails for the boat, and will have a clew that's higher and farther forward than they do.  Please confirm, and we'll get it in the works.  Thanks."

well the dimensions look about right to me,but the description of the sheeting is what i dont know
my 16 has just the original cleats in the corner of the cabin,

what do you guys think ? is it about right?
should i go ahead and order,?
all i want is a jib like the original one,

thanks,
Gabriel

Hey Gabe:
This is sort of a continuation of our last thread.

The original jib that came with my '89 C-16 measures:                                          Leech 12.75, Luff 14.08, and Foot 7.83 with an area of 46.51.
I was disappointed with the Original Equipment Manufacture (OEM) spec jib from National Sails that measured: 
                                                                                                                            Leech 11.83, Luff 12.16, and Foot 6.50 with an area of 36.48.
So I just purchased a lighter 3 oz genoa:                                                               Leech 13.13, Luff 14.42, and Foot 9.59  with an area of 61.36.

Areas estimated using Herrons Formula.

That genoa with the OEM main (57.17 sq ft) will almost give the 'book' sail area of 120 sq ft.

There seems to be much confusion about just what OEM is.

I recommend that you order sails by specifying the measurements.

On the brighter side I did manage to get that last sail by the 'Admiral' (=; so I will hit the lake in the Spring with a nice set of sails.

Gabriel,

I pulled out my jib (from my recently purschased '80 CP 16) fresh from SailCare and measured:

Leech 11' 10" , Luff 12' 1", and Foot 6' 6"

Gabriel,

It seems from the statement you pasted from the sail maker about sheeting, that their jib is designed for boats with genoa tracks (because they also make the larger genoas), so I would suggest that you make sure they understand that your boat has the jib cleats in the original position and ask whether that makes any difference.  Otherwise, the measurements seem to be in the ballpark for a 110% jib.

It is interesting that the first discussion topic on this forum (#39) lists sail measurements for the original model, with a caveat about the accuracy of those measurements, and a warning not to use them for sailmakers' orders.  So, I think that's good advice as suggested above about measuring the old sail, where possible, to use for purposes of ordering a replacement.

Gabi, I feel at a loss since I recommended Super Sailmakers as a source for new sails.  I've not ever measured the new jib (110%) I got last year, but am pretty confident that it was the same size as the original sail shown in the picture below.  (I'd run and measure it if the boat was closer...)


Looking at the size, does this seem to match what you received?  (You can make out the sheet in the picture, it's running through the cleat on the edge of the cockpit.)  I don't have a photo uploaded that shows the new jib to compare.  The clew for me has always been about as far back as the sidestay on any close hauls, and the sheet runs just inside the stay on reaches.

I feel that it's a handkerchief in comparison to the 155% genoa I normally have sailed with, which requires the sheeting to run outside the stays to the cleats at the rear of the cockpit.  I think I would reef the main before I went to a smaller headsail should the conditions warrant.
