It's an odd use of the expression 'single ply', plywood is made up of three or more 'plies' or layers, laminate sails are made up of three or more layers, typically two plies of polyester film and a third of some kind of scrim, all glued together.

Not sure what you mean by 'tape drive' in this context but I assume you are referring to UK Sailmakers variation of moulded laminate sail construction (first used, I believe, by North in their 3DL sails) where the sail is made in one piece over a former and the scrim is laid along stress lines?

Anyway, back OT, what actually is the class and the mod that is exiting so much attention?

Glad someone asked - I've been wondering if the question was PC.

PC?

Anyway the original question was just after a chat in the bar about what would happen in this scenario and I was curious to find out the truth from the knowledge forum here. It originates from Merlin's and putting a halyard bag in between the kicker/boom/mast.

Suddenly this thread makes sense and a protest is due

Before the haliard bag is made from mylar and attached to mast step,gooseneck and clew!

Is the rumour that new Merlins are north of 30k true?

Ok I get that it might be extra sail area but does it wrap around the mast/boom like the fairing does on the Musto/29er/49er might? That would definitely improve airflow that area though I'm not sure how much it would reduce overall drag, I suspect the difference would be considerably less than a missed shift or muffed tack.

Sounds like a cynical attempt to bend the rules.

Nothing cynical about it.
There's no rule to bend. That's the point. It's an open development class. You can spend thousands developing a lighter stiffer rig, faster sails, lighter build hulls (24kg of correctors as minimum!) When you invest in going quicker then went not look at every possibility? Or just keep the status quo? No new build, same sail designs, no development...
There's no rule about fences on rudders, so when does a fence become a wing (illegal)? How can you bend a rule when there is no rule?

Lens footed sails weren't against the rules either, or any of the other tricks.
