Have been trying to get one on and off for months from J Boats.

Any chance you would send me a copy of the Polars?

We've been using the polars from the J109 brochure. I enlarged it and laminated it and it lives in the one of the pockets (I have been known to consult it to see how we're doing while cruising, but my husband does make fun of me for that). Barry, is the data that you got from Johnstone better/more detailed than that?

Targets for PHRF and OD sails are also posted on the Quantum site.

Bslick,

I have all of the VPP raw data, would be happy to e-mail, have also sent e-mail to you on Sailing Anarchy forum. What boat do you sail? The data for the jib seems right on, for the Genoa seems a little low.

I use Doyle sails all around, D4s mostly, except for a very heavy duty carbon jib. They are about 30 minutes from my house/boat and have given me great support. How about you?

We use North 3DL, don't tell the Anarchist. We are very happy with the sails. The service was great last year, we haven't heard much from our guy this year. I am sure he will be calling over the winter.
We used Doyle on our 105.

I would also be interested in getting a copy of the raw data for the polars. Please email me (or upload to forum?). Thanks.

Mark,

This link has the VPP info. It applies to the hull, regardless of what type of sails you use:

I will also e-mail you the raw data. Perhaps we can get Kendra or someone else at Jboats to post the VPP data under the tuning guides section, so all can have access...

Chris, thanks for the link. Barry also emailed me the raw VPP data, which I am attempting to upload here.
