More like - "just because you can't see through it doesn't mean Dacron is rubbish".

The Lightnings have a choice. I went for Mylar on my first sail, but have gone back to Dacron for my new one. Absolutely no idea if one is faster than the other.

Good call by RS, in my view.

I'm still hacking around in boats with 20 year old (or older) Dacron sails. Whatever they give you in terms of performance (when new), Mylar sails seem expensive, short-lived and fragile. If you're supplying sailors with limited budgets who don't need that couple of percentage points of performance Dacron seems like a good call. I doubt there will be too many 20 year old Mylar sails in service.

Yep; dacron is cheap and durable so why do they just not get on and say that rather than spinning that line?

it is, but does it retain competitive life for as long?  Seems like a logical model to follow Laser and go for something stretchy... sure, it will last for a while for club sailors, but it's also one hell of a cash cow from the performance end of the spectrum who can easily stretch a sail in a couple of months regatta sailing.

How much do Finn sailors spend on a mast? What is the range of masts available for Finns? Why does North have a guide to measuring mast bend on their website? How compatible with is this with a SMOD?

I think 2457 is being quite clear, let's transcribe that video... just so we can see the facts as peddled:

people perceive nowadays that you must have a mylar this, that or the other.  When you've got an unstayed carbon rig and there's a lot of difference in bend in different conditions, you are actually far better with a dacron sail that stretches.

Fact or Hype?

Finn has an unstayed carbon rig
RS300 has an unstayed carbon rig
D-One has an unstayed carbon rig
D-Zero has an unstayed carbon rig

All the above seem quite fine with Mylar sails... did their respective designers get it wrong?

I think the Finn example totally defines Jo's explanation in the video - Rodney can help supply you a beautiful new Mylar Finn sail utterly tailored to your body weight, your mast and even the wind conditions.  The choice of fabric for the Aero is based on its ability to work well in a wide range of weights and wind to give it the broadest scope. Its not about mylar or any other classes choice, its about a design and fabric that was right for Aero. 

As its been mentioned before, this certainly isn't about cost - we could have sourced a mylar sail for the same cost as the production unit. The characteristics of this particular type of dacron (and there's loads of different deniers/qualities) was precisely what was needed from the outset to match the rigs.
