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.
(I have been one of those fishermen who have fished in the Tasman sea
for a living)
