Captain Frank's method is slightly different from the one suggested in Giuletta's excellent video. The video suggests heaving to to leeward by essentially gybing the main and leaving the headsail sheeted on the windward side. Captain Frank suggests getting on a nearly dead run, leaving the main where it is and moving the headsail across while it is blanketed by the wind shadow of the main, and thus sheltered from the wind. Of course if not for the rudder movement this is simply how one would move to sailing wing on wing. My concern in Captain Frank's method, which sounds reasonable, is that one had better be very careful to avoid an accidental gybe. With that caveat, I think I will give it a try.
On a run single handed (his case) would you not already have a preventer rigged? I would.
