With a junk schooner you can back the foresail, as well as putting the tiller up, so that as you make a stern-board, the bows fall off. You can do the same thing with a junk sloop, since the CE of the sail is a lot further forward than the CE of a bermudian mainsail. ie: you don't really need the jib. I sail off my anchor often. You don't need to put the full sail up initially, if there is enough breeze, just a few panels, which makes it easier to back the sail. You can push it out by hand, or rig a temporary outhaul on the boom, led forward. Takes a bit of nerve if the boats are really close though. A sudden windshift, as happened to me last year, can cause a lot of scrambling around! I'm no purist though, do it just for fun, and if I think the risks are too great I start the engine. But there are those, like Alan Martienssen on the schooner-rigged Zebedde, who don't have engines and are masters of this sort of thing.
