Bravo!
A very cool junk variation, drawing on a few past innovations in advanced cruising rigs.
Is there any reason besides appearance to the general population, which you mention, that the sails are triangular rather than quadrilateral, carrying more chord up higher?
We have a wishbone sprit boom rig on a dinghy. Only one wishbone, though, and no jib, but it has some good features. Not junk features, though, except squaring off nicely.
Cheers,
