I am very interested on developing alternatives to existing JUNK RIG DESIGNS based on a compromise reuniting the following premises:
1)The simplicity and easy of maneuver of the junk rig ( HARD IF NOT IMPOSSIBLE TO BEAT!)
2)Afordability of the same.
3)Windward performance of the wing or as a second... a well tuned up marconi.
4)The toughness of the gaff AND ITS EASY REPAIR.
Is that possible? Probably not as a whole but maybe ther are workable compromises.
That is what I am driving to, hopefully with the group's help....here it goes....
1) Imagine a junk rig were the mast is located at the center of the sail like a Dyna rig instead as on the traditional junk.
2) The battens would not be part of the mast like on Maltese Falcon but would slide up and down as on a traditional junk. Tha sail being well supported could be made of fairly light material.
3) the battens would be permanently CAMBERED AT ABOUT 5/8 DEGREES and MADE OF A fairly stiff BUT LIGHT MATERIAL, ALL PARALELL TO EACH OTHER, and prtactically horizontal, 6 to 8 of them controlled by JUNK LIKE PARRELS, on each tack very much like a Dynarig
4)The mast would be naturally UNTAYED, allowing the sail to swing with each tack and to lay flat againts the wind running and broad reaching. The rig would allow for a possible removable back stay to be use to reduce mast wipping in heavy weather or as an ssb antenna. THa sail would JIBE INSTEAD OF TACK, ON EACH TACK SIMPLIFING AND LOWERING THE RISK OF EQUIPMENT DAMAGE and making it self cocking
TWO SET UP OF PARRELS "COULD" help modify somewhat the camber if so designed.
5) The sail shape WOULD ALLOW FOR A MUCH IMPROVED winward shape on each tack (when compared with a standard camberered junk) an excellent when sailing downwind, same or very similar ease of reefing to the traditional junk.
5) one single sail per craft ( up to a moderate size boat) better performing that multiple set ups, more economical and manageable. The mast alway to leeward bu when running.
These are simply some "elocubrations" to open the forum/////
