Sail Re-Juvenation Myth or Truth

Hello everyone,

I came across to a website which is claiming re-rejuvenating dacron sails by treating them with some chemicals and resins (They call it Dacro-Nyolite)

Do you think such treatment would work?

Price-wise, it costs $1.85/sqf . (Not really reasonable, almost 50% of replacement cost)

Alternatively, I can apply the treatment by myself and optimize the cost. Do you know such chemical, resin, paint exist in the market? An aviator friend told the use clear polyurethane paint to to water and airproof the dacron material.

Have you ever tried this?

Thanks,

Tafa

You can make an old sail clean and newer looking. You can't reduce it's age and deformed shape. These are not worth the money. Have them simply cleaned to prolong life, but you can't turn the clock back.

My experience with Sailcare is that re-resining is a short term fix that soon vanishes. It does stiffen the sail up a bit, but it doesn't last more than a year or two if you use the sail much at all. And the older the sail (in my experience), the less time it lasts.

In my case, since the price was right and I was only keeping the boat another year or two, I had it done. For me, it was a good value.

I will second Minnewaska's & PBzeer's opinion with a caveat.

Having the sail reconditioned will stabilize and extend the life of an old sail, but it is still an old sail. The stitching is still weathered and the shape is what it is. So from that viewpoint, the sail won't perform any better, but it won't get any worse either. At least not immediately.

I would not even attempt to recondition a sail myself. Sailcare's process is patented and involves taking the old finish off the sail and re-impregnating the material under pressure. Their price in $0.95/sqft, with discounts during boat shows and in the fall. I have used them 3 times on 2 different boats and was satisfied with the results. Their customer service and sail repair capability is excellent. With that said, a reconditioned sail is only good for so long. We have since replaced our sails with new ones.

BTW - Sailcare also offers new sails. I believe that they are constructed offshore. Their new sail prices are average and would not be my first choice for a new sail.

I don't see how this chemical could possibly draw in stretched out fabric in a blown-out sail. It's like "tummy tuck in a bottle". Snake-oil, if you ask me.

I don't see how this process could change the stretched out shape of an old sail. Maybe recutting the seams to original specs and then using this chemical process could work but how much cost difference would there be compared to a new sail after all that work. It's great to re-use stuff but I would question the effectiveness. Would like to know how they repair the inevitable UV damage to the molecular structure of dacron.

The Sailcare process does indeed "tighten up" the sail throughout. How, I can't say, only that is my experience with having the main on my H 26 done.

One other caveat, if you're going to be keeping the boat for any length of time, you're better off to get a new sail. They aren't going to get any cheaper, and you'll have to buy any sooner or later.

Let's see... I just got a quote on a new mainsail for my Cal 2-27, which was about one kilo-buck (nuthin' fancy, just a basic Dacron coastal cruising main, loose-footed, two reef points). The main is about 160 square feet. So we're talking about $300 for a treatment that will make the sail look nice, and give it a little better shape for a year or so, verses $1000 for a brand, spanking, new sail that will probably last at least 10, maybe 20, times as long.

No brainer.

Let's see if I can add anything of value to this topic -- no promises, though.

I think the results of the outcome will depend a great deal on just how bad the old sail currently is. If it's old and grungy, but still has a decent shape, then the SailCare treatment will probably be good money spent. We had our 120% genoa treated -- and had a new UV band installed -- several years back and have been pretty stoked. When we we're bending it back on the r/f foil, lots of passersby said "ohh, new sail!"

If the old sail is blown, then treatment probably won't do much good as far as performance goes.

Should you send your sail to SailCare, they'll inspect your sail before they begin any work and let you know their findings. If there's a need for restiching or hardware replacement, or any other minor issues they'll annotate all that on a work order, which they'll then send you for acceptance and approval before they get underway.

If, in their opinion, the sail is not worth repairing they'll also let you know.

As I recall, most customer comments about SailCare and their customer service on this site (and others) have been almost unanimously positive.

Hope this helps.

Thanks a lot everyone.

I did not know Sail Care and thanks for the information. (I was referring a local Ontario service provider). And it's great to hear your experience with them as well.

My findings from this thread;
- Don't even think about re-resine the sails DIY way.
- If you believe the sail has min. 3-4 years life left, consider Sail Care as an option.
- If the sails are dead, they are dead.... Don't try to bury them Stephen King's pet cemetery

Thanks again everyone,

Tafa
