Rooster 8.1 rig on Laser

Now there's a good idea.  I'm not over 90kg but if I was sailing regularly inland I'd give that a try.  What particularly attracts me is that the sail looks like it will last longer and will set better.  As a bonus its all a lot cheaper than Laser.

Seems like an interesting concept to me; guess it's a case of "watch this space"...

I wonder what Laser think of it

You're thoughts were precisely mine, JimC, the moment I saw the thread title.

In fact I've been wondering how long it wouldd take for someone to come up with a Byte C2 style rig for the Laser - a bit longer still, apparently.

You could up the area over the Laser's 7.1,  given the extra efficiency, as you say, Jim, but the problem is you never get as much as you expect - as you up the area, so you raise the centre of effort too.

But 8 - 8.5 m2 would probably be about the right size, I guess...

I see Rooster are claiming a PY of 1051 for it.

That strikes me as optimistic, not least because it's rare for a Laser to win on PY anyway, but mainly because they're expecting a 2.6% performance gain from a 14% area increase, when the full rig only rates 2.1% faster than the Radial despite a 25% increase in sail area.

Surely the efficiency can't be that much better? - the cut pattern is similar to the original, now superceded Byte sail.
