Luna Rig - good, bad?

[barnakiel]

Hi,

What do you think of this rig?

I found it here:

CARTER 35 (LUNA RIG) Sailboat details on sailboatdata.com

I prefer to stick to what is proven. I leave to deeper pockets to do the experiences

[atoll]

not very good for motor sailing to wind ward,with no main to sheet in hard.

Ahhh.... a boomless Schooner....

Looks like that boat would be better served with a twin masted junkrig set-up. Lose all that standing rigging and simplify the sailplan. My .02

How about sheeting in the aft jib?

BTW Is she a motor-sailor or a sailing boat?

But then (with a junk schooner) the fore mast is way fore and being so much fore it has to be carbon to stay light!

Also, upwind performance would differ, would it not?

And then, it is so darn easy to roll in two jibs!

That would work.... with a dedicated sheet...

The foward mast might need moved a little foward as that depends on a few calculations, but it doesn`t have to made of carbon. The JRA Junk Rig Association can provide all the details of a conversions requirements and very few junks use carbon fiber mast.

Upwind perfomance will be less optimal that a standard bermuda rig, but will still point none the less, and tacking/jibing is 100 time easier, not too mention reefing is a dream. Sell off all that standing rigging/mast/winches(junks don`t need nearly as many) and the conversion could pay for itself.

But the winches are already on that boat anyway, so there is no problem with controlling the sails. It the jibs are built self-tackers then there is no need for winches either!

I mean this particular rig - not vis-a-vis others that we know are around and function - what would be its pros and cons?

I thing that with 2 furlers balancing the boat would be superbly easy. Then again I think downwind the boat would need some extra toys - to keep the jibs 'open' or poled out ... Then I think the sail area does not look huge but maybe this could be helped with longer footed jibs?

Just thinking aloud.

I would guess tacking doesn't get any easier then with the luna rig. A great rig for a down wind run too. Spreaders wouldn't rub on the sails so they would last well. A pretty simple rig.

No doubt downwind performance would require some additional equipment. Simple rig for sure!

Perhaps a Hoyt boom or self-tacking jibs could be used to this end too.

Yep. I like the simplicity when it comes to reefing. Suppose furlers are employed - no need to go on deck to tie the bunt or put the tack on the hook etc..

Then I also like the simplicity of the canvas - it is so easy to build and fix a jib - no battens, no hardware, etc..

And when furled - the sail can be deployed in no time - another big plus.

The negative side could be, as I see it, that perhaps two jibs could not be enough - maybe in light winds something lighter and bigger would have to be flown, or else the masts would have to be quite tall to allow for good amt of canvas.

The positioning of the aft mast certainly maximizes the sail area it does have. Searching the net finds mention of other Luna rigged Carter boats, the 50 and 53 for instance but I can't find actual examples. A bit of a rare bird?
