But back to the question at hand. Sailcare is more than just a re-resin process, I know they also fix sails, sew, reshape, cut, and generally do most of what a loft can do, but also clean and re-resin sails. Honestly as long as you aren't expecting a NEW sail back from them they are a viable option for keeping an old sail functional. I am actually considering hitting them up because I have a 30yo sail I rarely use, that is actually OK except for a pulled stitch in a couple places, and it's missing a leech line. IF I could get a new leech line on it, and repair those couple stitches... then clean it, and such, the sail itself is actually not blown out. Might be a good beater sail then. Right now it's nearly useless because it luffs like crazy without a proper tensioned leech.

I would say don't do the re-resin process more than once... it's really a process for your "practice" sails, or second string sails. If you primary racing sails are in need of care, I'd say they likely need to become your practice set, and it's time for new ones.

Oh and Catalina 25 you say? Check out http://www.catalina-capri-25s.org/ No this is not a commercial, its the class association for the Catalina 25.

stiffen sails - how often?

Recutting a sail is something that only a sailmaker should perform. They will look at the sail and see whether or where it needs improvement and add or remove cloth as necessary.

Technology being what it is, most sailmakers can use a photograph of the sail taken from mast head or foot and software can calculate whether a change is necessary. It's important to realize that a sail is not a triangular piece of material that magically catches the wind, it's an airfoil and lift is everything. Shape = lift and most casual sailors have very little idea what the correct shape should be. In short, recutting a sail is not something an amateur should attempt, IMO.

We have a pretty new genoa made by an offshore loft. I thought that the luff had too fine an entry and the whole thing was too flat. Our current sailmaker ran a photo through their software and proposed recutting the luff and wading the back stay. They added a tapered strip of cloth along the luff and the result us a far better shape that is easier to keep in the groove. Amazing what a 1 1/2" piece of material in the right place can do.

I have had two mains recut - different boats. Each time they took some fullness out of the center by taking apart the old seams (these were standard panel dacron sails).

They took a calibrated curved slice out of each side and re-seamed. Part of the cloth removal, and it was subtle, was bringing back the whole curve shape to where it was before years and wind pressure had migrated it aft.

Cloth was in good shape and not rotted. It worked wonders for another several years until I could budget for a new main. Not sure if all seams were opened.

I do recall that when a new quality dac. sail cost about $1500, this was only about $250.
A bargain, all things considered.

Thanks to all who answered - I'll clean (wash) the sail myself for the winter and put it away.

Re: stiffen sails - how often?

As Sabreman said I also have used Sailcare® located in Ford City, PA for the cleaning, repairing and re-resining process and was impressed with the crispy, white sails they returned to me. As said, if the sail is blown out, they remain blown out, only much nicer looking. Its not a process you would want to do annually however, as it is rather expensive. Perhaps every 5 years or so.

Re: stiffen sails - how often?

Yes, the sailcare offering seems to have mixed reviews. Some say it makes them like new, others have issues with shrinkage. I think as to how often, I don't think you would want to do it more than once. Seems to be a last ditch effort to try to save an old sail, not really part of routine maintenance as far as I can tell. I am sure Sailcare will say different, but that is to be expected. I think for someone who races once a week you would want to consider new sails not "stiffening" and I would consider once a week pretty often. Now if you raced a few times a summer that is different.
