Delicious! A mixed fleet of those should look goodAny thoughts?
Extremely good, fundamentally. Those rigs are in turn based on 18-footer research, so we're talking about the pinnacle of dinghy design in general. Bethwaite also designed the CI and CII rigs for the Byte, so he should know how to apply the skiff technology to una-rigged, unstayed boats. But it doesn't really answer the question that was asked in the comments, that is, why do the C rigs have the boom so low?In a comment, Doug says the rigs are the result of 29er and 49er research. Good or bad?
The boom seems very high on the C rigs.
Just measuring from the pictures, the gooseneck on the C rigs is roughly 30 % lower than on the current masts. The "ducking height" of the boom is another matter, and from the previously released video I'd estimate that there would be little to no change.The boom seems very high on the C rigs.

I agree that they could have raised it a little while at it.

Ok. It has nothing to do whether the vang is pulling or pushing, but yes, it looks like the aft end of the C-rig boom won't get very close to the deck, ever. That means the traveller probably needs to be trimmed (and if rules are changed, possibly even rigged) differently. That in turn might mean no need for carbon tillers anymore, which would save more than a hundred € or $ per boat.I was looking at the end of the boom. With the reverse vang I don't think the new upwind trim will be anywhere near block to block though right?
Doesn't look nearly as good as the PSA effort. What does LP think they're gaining with this? Anyway, they now seem to have extended the two lowest battens all the way to the luff. Also there's now a "Sails by Laser" patch (like on the Radial and 4.7 sails) at the tack instead of a Doyle logo. Maybe they think it's more "official".And away we go!
There have been different solutions to this in different classes; the 29er has a round tube, while the 49er has two parallel square tubes, with a lever plate in between. All that I have seen (including ones on the Laser 4000, Musto Skiff, etc.) have been made of aluminium, straight and not intended to bend. The C-rig vang struts do strangely look like they are straight in some pictures and (pre)bent in others. No idea what that is about.It looks like the vang is above the boom and acts in compression. This must be some kind of stick, rod, or tube. I assume it is a substantial piece in order to prevent it from buckling. It looks curved - does it flex in use? Is one end in some sort of track? How is it adjusted? Does a control line go down to the deck?
No, the other piece wraps around the mast and attaches to the other by a zipper. This is clearly shown in the video.IIt looks like the foot of the sail is two parts with each going on its side of the vang and boom and then joining near the bottom of the mast, right? Are there two mast racks below the point where the sail splits?
With full-length battens, mast bend is quite effectively adjusted by cunningham tension. What LoonyGryphon has told is that the cunningham and vang adjustments lead to the existing deck blocks and cleats while the outhaul stays on the boom.The similarities to a modern sailboard rig are clear. Do these "C" rigs use large amounts of down haul tension and relatively light out haul tension like sailboard rigs? Control line on the deck? I can see what looks like a large block on the deck near the mast.
No halyard in sight. It's probably the same as with the new LP rig: the sail is "hoisted" from the top down, before putting the mast on the boat, like we've always done... except there's a bolt rope and a track now.There is apparently a track in the mast for the luff of the sail. Is there a halyard so that the sail can be raised with the mast first placed in the hull?
What are LP trying to achieve? They said the ARC rigs were for the Radial and standard, which they most obviously are not.
This is getting off topic, but actually the rudder is the only part of the Laser of which Bruce Kirby has said he'd redesign. Elliptic with 30 % more area, if I remember it right.the rudder is simple and excellent.
