Don't really see how an answer given here has any weight at all.

well the first query was closed rules hence the we think it might be illegal. On checking further we found that sail coatings aren't mentioned nearly anywhere, either in RYA, WS or ERS.....
In fact we found that quite a few closed class rules champions were quite open about using sailkote or similar on their olympic sails or star class sails.....

So if closed rules and an RYA class it is any RYA measurer or IHC.  Does it matter who the arbiter is? if the rules don't specifically mention sail coatings then they are illegal? even if you buy them like that from the sailmaker (specifically Contender dynakote, gets a treatment after manufacture - not an impregenated finish).

How any measurer would be able to tell that a finish has been added after i have no idea. Now we supply Ultramar and they have a better product than the silicon, is it allowable? i get the feeling that no class has ever thought about it before (the fella who asked me is a bigger pedant than i!)

I sailed a strict one design assymetric class and the whole fleet got the kites coated or fabsil'd them after purchase from hydes. so an additional finish / protection /polish. Looking back as the rules were closed we were all cheating or were we?

It is a forum, as in for discussion.

I agree recoating sails is fine but if a class specifically disallows a certain coating then it is an open and shut case.

I quite openly get mine done. Not my open meeting kites as they are new. But as soon as they need replacing, and it prolongs their useful life. No one has ever complained or protested. Only asked who I get to do it do they can send theirs too. Seeing a kite that the week before was a wet rag slide effortlessly from the sock and shed water is all you need to see to be convinced. It is also not very expensive.
Anything that prolongs the length of usefulness has to be good.

Ps I send mine to Scam at Suffolk sails. rejuvenated Musto Kite still good after 2 seasons use. Much better than do it yourself waterproofing.

thanks Doc! 
the query is that a strict one design was offered the process and it bought up the fact that a sail was outlawed because it had been painted (not sure if it is true or not).
Some classes outlaw certain cloths and certain sailmakers use a cheaper ripstop that only has a pu coating and not silicon, then get the sails silicon coated after... so depending on which sailmaker you use you might  be altering the characterstics of the cloth.
Just for once this tin of worms isn't mine!!
PS scam is a nickname LOL!! Simon @suffolksails

But if you race with other people under the RRS then breaking class rules is cheating, which sounds as if its what the OP is trying to avoid. If all you do is cruise round the bay do what you like.

More likely the coating will bring a sail back to nearer what the original characteristics were.

You would fall over on this though:


Rule 26 a: Repairs and preventative maintenance to the sail, hull, deck, centreboard, rudder, mast, boom or any fittings and fixings may be carried out without violation of these Rules provided such repairs are made in such a way that the essential shape, characteristics or function of the original are not affected

As the coating may alter the characteristics over what it would have been originally.

You could probably class spinnaker coating as coming under maintenance.  A quick look at the laser rules suggests coating the main could be fine.

Rule 26 a: Repairs and preventative maintenance to the sail, hull, deck, centreboard, rudder, mast, boom or any fittings and fixings may be carried out without violation of these Rules provided such repairs are made in such a way that the essential shape, characteristics or function of the original are not affected

Rule 26 f: The use of lubricants is unrestricted except that they shall not be used on the hull (below the gunwales)
