M_Boats: junk rig on an M15

Has anyone tried a junk rig on a Montgomery 15? I have boat #191, and I am coming to sailing in my late sixties. Consequently I'd rather stay off the foredeck in difficult weather if I can. (My intended sailing grounds are San Francisco Bay and Tomales Bay.) After reading several books, notably Annie Hill's Voyaging on a Small Income and Hasler and McLeod's Practical Junk Rig, I'm convinced that a junk rig might extend my sailing life. And I think it would go nicely on an M15; but I'm wondering if anyone has experimented with it before and figured out mast placement and mounting etc. Thanks, Tom Nixon M15 #191
