Thanks for that clarification  Arne,  Very much appreciated!

Not sure of this thread is still active, I am in the throws of building a folding inflatable dinghy with an origami split junk rig complete with single sheeting.  It is a grand experiment, and I am using 3/4" and 1-1/2" webbing, white tarp, white duct tape, 1/4" grommets and 1/8" low stretch poly line.  I am currently assembling the sail, which has a 5* deadrise, aprox. 1:1 aspect ratio and an area of 4 sq m or 43 sq ft.  It is tapered luff and leach toward the top, and I am using one piece battens out of 3/4"x3/4' clear fir.  It is, as I said, a grand experiment.  It will also have a built in sail catcher, a mast the is in two pieces (1-5/8" tube, with a 1-1/2" inner sleeve 12" long, and I plan on shock chording the two pieces giving me a total length of 12'.  I can always cut it down if I do not need that much height for a good angle between the top sheave and the sling point.  Instead of using parrels, I am going to attempt to use tied loops of line, or webbing with grommets, attached to the horrizontal batten web ( 1-1/2") to hold the sail battens against the mast and fix their position for and aft  so it can rotate around the mast for transportation and brailing up against the mast.  This will be important for storing the sail bundle with the mast, for transportation and storage.  I plan on having the mast and sail fit into the sail bundle, in the sail catcher.  Wheewe!  That was a mouthful!  My house has turned into a sail loft and boatworks!  I have a sail making and grommet station in the basement, the living room has three camping tables and a sheet of plywood with the boat layout on it and I have a wood working shop and a dome for outside, messy work.  That is it for now, to work!  The sun is shining and I am getting bleary eyed from watching the fall of the Canadian government's draconian mandates in the age of Omicron.  Cheers from the west coast of Canada!

My experience with two-masted rigs is with bigger boats, but yes, the cockpit does turn into a rat's nest at times, and I would guess that in a gust, you might find it troublesome to find the right rope's end to ease away. I'd go for one low AR sail, with four sheeted points.

In dinghy rigs, I've used 16mm GRP pultruded tube successfully. Yes, the battens should be as stiff as possible, but it's possible to make them too light in a small boat, so that they don't drop readily. If GRP tube is not available, then thin walled aluminium will be fine, probably 16mm - 20mm diameter.

It's not possible to make the yard too light; even in carbon fibre it will be heavy enough to drop readily, so this is where some weight saving is useful, in a light and tender boat.
