That seems highly unlikely, if I may say. There are classes in which you have been allowed mylar in which dacron proved to be faster, and OD classes in which Mylar sails were allowed but showed very little improvement in speed over good dacron. 

As a comparison, I have old copies of yardsticks from the days when dacron replaced cotton and there were yardsticks for both cotton and dacron sails. Dacronj allowed bigger roaches in many classes, as well as being less porous, but was still handicapped only about 1% faster IIRC.

2014 Y&Y forum's Laser Killer is.... the RS 50.  (I think that's what's being mooted anyway)

The UK has a very complex and mature (shrinking) market for racing dinghies. I would not particularly bother promoting that boat in the UK too heavily despite the local allegiance and brand loyalties.  It'd only end in boom/bust with class politics kicking in, not to mention the handicapping issue... possibly spreading a negative vibe to other more lucrative markets.

I'd package it up with a fusion of of beachside Aloha and Brit Hip - then close the deal with Sheikh funded institutions in the middle east, the rapidly expanding middle classes in China, Singapore, S Korea and sell a bit of design Kool Aid to the American college network- at 5 grand a pop those puppies would roll out if marketed as something new and different.  Their new Antipodean dealer network ramping up demos for organic growth would also be a key goal- win the Aussies and Kiwis- they are the sailing elite of the moment.  None of those markets have the same intensity of issues faced launching here.

Launch a new dinghy targeted at Brits... no way, we're not worth it.


Old post, new reply...

Can't see a new singlehanded hiker working down here. We already have two very strong classes in that category (well, three with the Radial) and because of the culture, sailing scene and distances it's very, very hard to create a new class in a new market sector. Creating a strong new class in a market sector that is already well catered for is another story indeed and has not been done for decades.

A year ago I moved to a very nice area that had no two-up dinghy OD fleet. It's been (for my taste) a horrible experience that has taken much of the joy from racing for me. Thank god the Laser fleet has been there as a lifeline of (IMHO) proper sport. Why would we throw away good racing so that we can run around in a group of different boats, where it was hard to know how well we sailed and where doing well came down to who got the right conditions?

In some ways, creating new classes is like loving cricket but deciding to play 10 a side with three batsmen in at once, or loving chess and deciding that all your pawns can do backflips and use death rays on rooks, or putting fairings and expecting to race with your bicycle club. Yes, it may be more "efficient" but you end up losing the vital critical mass that is so vital in an effective sport as well as making it all more expensive and losing many other things that make a sport a sport. I admire RS but I am completely against attacking one of the few classes that is strong in a sport that is struggling in many ways. 

And Jon, of course some of us will get upset if you abuse the boats we love. We don't abuse your boat, wife, child, car, house, etc. Why can't you have the respect for us that we show for you?

Mylar has very little give whereas Dacron has more and can exceed the performance of Mylor on a unstayed rig with lots of flex. Mylar works on a Finn because it has a very stiff mast and the same on the d-one as it has to be stiff to hold the kite without stays. Both. The 300 and 100 use Mylar, but both have a Dacron panel running the length of the luff for that very reaon.

You're making the assumption that performance is the prime reason for such choices in a SMOD class. I don't think that's valid. The job of a sail designer in such a class is to produce the rig that will help sell most boats, not the one that is fastest round the track - arguably a more difficult task.

I think to make judgements on performance you should look only at classes where there are no rules that influence material choice and where the distribution is wide enough that local sailing culture biases don't come into play. There aren't too many...

But then, if what we are considering is a rig for a new SMOD class then sentence 2 comes into play and performance isn't all that relevant anyway.

In the Lightnings, Mylar has been racing Dacron for 5 years, now. Once you take into account that most of the regulars at the front of the fleet bought new Mylar sails, so often win stuff, there appears to be little difference in speed. Oft time champ, Louis Saunders (iiiiiitick's "Boy") still uses a Dacron sail, and 3rd place at the 2013 Nats was taken by a boat with an old Dacron sail - the old made a difference, not the Dacron. I'm saving my pennies (and £'s, or it would take too long...) for a new sail, and I will be buying a Radial Dacron sail. If there is a difference, it is that the Dacron is easier to read in a drift, and the Mylar has greater stability once dogs are being blown off chains. Between, it all seems pertty even.

Certainly no 15% speed difference.

Does the Mylar sail last longer?

The Mylar sail probably has a longer life in "perfect" condition, but once it starts to go, deteriorates far more quickly. I was using my son's 25 year Dacron sail today, and came 2nd. It has probably had 23 years of use past "as new" condition, but is still going. My 4 year old Mylar sail is showing signs that it is going to turn into shredded plastic soon.

No, not making that assumption at all. Cost and price comes into every boat, but Dacron and Mylar have different stretch properties and that is why they are in both sails I referred to.

The masts were pretty flexible on the prototypes and the dacron sails worked very well. A film sail may sell a few more boats initially as it is perceived as 'modern', but short-lived if it doesn't really work with the mast.

So what did we decide? Does the world need a new una rigged 13-14ft single hander to replace the Laser/Torch/Phantom/Solution/Blaze/ 300/eps/Moth/OK and if it does will people throw their old boats away and spend 8K on a new one so that class racing continues to take place at their clubs? And is this it? Or are we still waiting for Europe to notice the Sunfish?
