Darryl,
The technique you describe is (I think) what most beach-cat sailors do. But I do not believe that will bring the boat head to wind. As I said, 45 degrees is about the best that seems to be achievable.

Bill Roberts said exactly what I was thinking: The only way to do it without using a drogue is to put a crew member in the water -- someone with an appropriate amount of drag to serve as a drogue.

That may not be financially feasible, especially if the designated drogue happens to be your spouse. And especially if you happen to be sailing in ocean areas inhabited by large, aggressive, carnivorous animals.

At any rate, this thread is about righting a boat solo, so without a drogue (or a crew that can be a drag), I still am very skeptical that it is possible to get the boat's bows closer than 45 degrees to the wind.
