James,

If you put a "return" in the middle of your links, after you've made them, they still work, and the rest of the text then fits within the box, instead of bleeding off at the right hand side.

After some tantalizing research on square top sails, and quad jibs, I may be able to create an effective new variation of a rig.

Thank you David for that fascinating link.  It makes a lot of sense to me.

After some hasty measurements between breaks of rain, If I do a quad jib, I think I will most definitely have room available to set up the junk rig style sheeting on the fore sail! 

The head sail would be just a square headed triangle, with the beautiful sheeting scheme Arne has graciously shared with us.

Currently I believe there should be between 5 and 7 battens, paper models will determine this.

Construction would be very straight forward if using horizontal panels assembled at the batten pockets (or joints, I'm leaning towards oak battens, as they are cheaper then Aluminum, so I may tie the battens to the sail, so if one breaks I can more easily repair or replace it underway.)

I predict this rig will perform better then my current sails, being they are all stretched, and almost as old as my parents. I think the rig will stink in light airs and I may need to run a 150% genoa still in anything below f3, mainly due to the weight of thick fabric,  and heavy battens. I also think it will perform worse then a normal junk down wind. Obviously the stays would prevent a full swing out for running down wind.

The only benefit I can see this having over a split junk or aerojunk is that it would allow one to retain their original stayed mast. Overall, I think for my purposes of coastal cruising through the summer, and until I fulfill all of the structural prerequisites prior to installing an unstayed mast. Who knows, this can surprise us all and turn out to be a great little rig for someone on a budget that wants an easy to manage DIY rig. I just really love sailing, and would field a guess I probably can sail about as close to the wind as a flat junk with my current suite.

Hopefully this is as entertaining for you to muse about as it is for I, so keep contributing your input!

I dub this project the Bermudajunk!

EDIT: There was a fantastic theory I read about square heads on sail preventing turbulence between the low and high pressure sides of sail, so maybe if I make the jib a parallelogram, the head sail may benefit from this proposed effect, or it may just further reduce sail area, so I have more stewing to do on this thought.

UPDATE: I just took a trip to the hardware store to price red oak 1x2, and it turns out 1 inch alloy conduit is cheaper, and comes in a 10ft stick instead of 8ft. I will be going with batten pockets to hide the ugly alloy, plus I doubt they will break. I may use something lighter such as fiberglass cored pvc pipe for the battens on the head sail to reduce weight and optimize light wind performance. the battens should be short so bend should not be too great of a concern. The extra weight from the alloy may allow for easier reffing, so that option is still on the table.

Here is a quick sketch of a potential jib plan.

Thanks for the input David.

I would sacrifice the self tending jib abilities, and rig the sheeting as a "semi-auto" sheet as illustrated by The Riggers Apprentice. 

I just got a nice 5 min break from the rain here, so I hopped on deck and briefly examined my rig and those around me. I think If I proceed with the experiment I will maintain the original triangular shape of the sails. It just looks like that will work best with my stays. I have 1 year old new stays that have only had a handful of sails in light weather with stretched old sails, and just plan to putt about around in protected waters with this set up.

I need to make up some drawings, but it seems like it may be a fairly straight forward little project. What I am still scratching my head about is how to implement an easy to reef system from the cockpit. It would be fantastic if I can get away with one downhaul/ reef line per sail, but I have not cracked it yet. At the moment the only idea I have is to run a down haul line along the luff and the leech of each sail.

I may use 5/16 line to keep down on cost, and because my current halyard is wire, but may accept the 5/16 in line. This means sailing the rig would be a gloved activity. I can see this being annoying so I may just use it for the halyards.

EDIT: I am also researching quad jibs

I have decided that it might be fun to do a sail experiment while I wait to have the funds to do my junk rig conversion properly with 6oz Darcon fabric, built on an aluminum flag pole.

The purpose is to test out some ideas, get practice sewing large amounts of fabric into sails, and test some really quite nice looking polyester pvc backed out door fabric that is $5 a yard at a local department store. It is said to be water proof, and UV protected. If I like the fabric and it performs well enough then I may consider it for our junk rig.

I feel it is wise to practice my sewing and get some experience before trying to build a sail of Darcon. That stuff is really pricey and seems unforgiving to work with. 

Since currently I have a stayed mast to work with at the moment, I plan to build a simple jib boom and install that for my foresail.

I want to try and make a more square main with 7 heavy battens of aluminum tube or 2x1 lumber. I also want to construct the 90% Jib this way.

Think of Bermudian sails constructed in style of a junk rig. It would be fun to have a boomed reef-able jib with 9% camber possibly constructed using 45 degree shelf foot, and a main with 9-10% camber using round or round and broad seam.

I think the construction of such a project would answer a lot of questions for me and help me determine which platform to proceed with. Who knows if it turns out I'm a great sewer I would probably go with a splitjunk, but if my skills are lacking, the aerojunk would be for me.

I think I have it figured out for the most part, but need to work out the sheet/ down haul situation to try and make reefing as easy as possible and all from the  cockpit.

If you have any input, suggestions, or links I would greatly appreciate them.
