Bob, although I realize you know of what you write, I find your
statement confusing. The primary use of a drogue, whether series or
conventional, or simply streaming warps, is to keep a (sail)boat's speed
down and prevent it from
surfing while running downwind. Of course, it does help to keep the
stern to the following seas. There is much to be said for a double-ender
or canoe-stern in these conditions, and much less for a boat with a flat
transom or sugar-scoop. I surely wouldn't want to utilize a drogue on a
boat with a conventional trawler stern. I'd deploy a sea-anchor off the
bow if I had to heave to; I certainly wouldn't run off or heave to by
the stern! Yikes!

I'd also be cautious of using Dashew for an example. Dashew is foremost
a sailing man, and despite his "unsailboat" (an unfortunate name, which
seems to have disappeared in favor of the FPB83), it is very much like a
sailboat. This is a
very unconventional boat; quite unlike a trawler.

The series drogue will do that. But in the "ultimate wave strike", is where
it is designed to keep the boat from pitchpoling or  being rolled. All
older styles of drogue will not be as effective in that regard as the
series drogue.
