Well then, my hat is off to you. :-)
I also really like the theory of paying out more or less of the
drogue line depending upon how much you want to slow your progress.
What I like about the combination of a Harry and a jordan series
drogue is that if you want to slow the boat to almost a stop, ie a
para anchor, then you merely pay out more elements to you get to the
same total area of the equivalent para chute anchor.
There has been derision about anchoring from the stern without a
solid explanation why. On some boats it is quite successful and much
more comfortable in that it reduces yawing.
