Started a new thread as lots of talk about it. You should try this sometime. You will be amazed at how easy it is and how tight you can get the headsail.
"Heaving-to downwind can be accomplished by bearing away from the wind until the headsail is blanketed by the mainsail. When the headsail collapses onto the foredeck it can be hauled tight to the opposite side of the boat. Once the headsail is secure, the boat is slowly rounded up into the wind. As it rounds up the boat will stall and come to a stop in the heave-to position. The advantages of this maneuver are two-fold. First, it relieves the crew of the effort in getting to the close hauled point of sail before heaving to. Secondly, the boat remains on the same tack and does not have to tack back to continue on its course."
