Here's an interesting article: A Trinity with Vision | Cruising World

It seems Bob Perry started out in Carter's office.

Chattcatdaddy,i think the suggestion of a carbon fwd mast on a junk rig on this boat was because most western hulls like this dont have the volume fwd to support a heavy mast like a chinese hull does. Unless the sails on the Luna rig were to be set up for self tacking it is not as easy as a junk to tack,in fact it seems to me that short tacking up a channel you would be busier than a one legged man in an ass kicking contest, a sloop would be easier. If you did set it up to be easier to tack with a Hoyt boom, traveller, club boom etc, you would be sacrificing the sail area to be gained from overlap.

I don't understand the difficulty in tacking the Luna. Ease two sheets and haul on two. Nothing to interfere with the sail coming over. Am I missing something?

And why "Luna" anyway?

Boatyard? Boat?

My guess is it the opposite of an una rig. I have no idea why it's called an una though ....

hummingway,im not suggesting its difficult to tack, its just that when tacking a sloop all the work is in tacking the headsail particularly with genoas, as the main is self tacking, so, two headsails are more work than one, unless of course they are self tacking, on looking at the sailplan it doesnt show overlapping sails so maybe they are self tacking. When racing we love it when its #3 headsail conditions.

Reviving an old thread here with first hand info. The Luna rig, named as such by Dick Carter for his Luna project in the early 80's. The most notable Luna rigged boat being the Vendredi Trieze (3 mast, 125') designed to be the largest possible boat that could be handled by a single sailor, with the purpose of racing across the Atlantic. As a later development, several other Carter designed boats carried this rig.

I have been sailing a Carter Offshore 50' with the Luna rig. It carries a generous 9.5' retractable keel. As best I know it is called a Staysail Schooner. The two furling sails (jibs) are self tacking making a breeze of upwind work (just turn the wheel!). Each jib sheet has a traveller to control sheeting point athwartships and can be sheeted in tight to center-line. Combined with the deep draft the boat goes to windward very nicely and at a respectable angle. Roller reefing the "main" usually achieves a well balanced helm when the wind pipes up.

The rig carries a removable internal forestay to carry a staysail but as this gets in the way of the self tacking jib it hardly gets any use. The boat is happiest with winds over 15kn and the sails can handle wind into the high 20's before needing to shorten sail. For lighter winds it would probably benefit from a larger, overlapping genoa, reacher or Code-0.

The 2 jibs are not the ideal setup for significant downwind sailing and the boat would be well served with a suite of dedicated downwind sails. However the boat came with 2 spinnaker poles and a Fisherman Sail (which is the lovely inverted triangular sail that is set between the masts).

Gybing also becomes a non-issue with nothing more than some cloth flapping when crossing behind the wind.

So to sum it up; for ease of sail management the Luna rig can hardly be beat. It is easy enough to sail the boat single handedly in most (benign) conditions. Laughing simple to tack and gybe. Great rig for most cruising needs.No boom to shadow the solar panels on the pilothouse. Maybe not as efficient as a modern sloop rig but not in it to win races.
