Ken,
Be careful here. I had a very similar conversation with Don Jordan
exactly one year ago and also the people with Ace Sail Makers. Don
concluded that because the figures for the 35 ton boat were for a
sail boat, the series drogue for a similar sized power boat needed to
be larger. Flat Earth is a 40 ton boat and my series drogue is
490'. I don't remember how many cones it has. That's 25% larger
and my boat is less than half the size of yours. I do think he may
have gotten a little carried away in my case, but ask Ace Sail
Makers if they have the design data for Flat Earth (probably in my
name).
I hadn't 'broached' this subject before on the list with regard to
the series drogue, but data indicates that there will never (well
maybe just seldom) be a wave breaking over the transom into the
cockpit. Rather than fighting the waves, the series drogue appears
to allow the boat to float with them somewhat and waves simply pass
under the stern. I probably didn't describe that quite right but
that is the jist of it.
Deployment for me could not be easier. The drogue rests in a dock
box in my cockpit. I have snaked it into the box so that the two
ends of the bridle are on the top of the box and also the very end of
the drogue that carries the weights. To deploy it all I have to do
is attach the bridle loops to the cleats on the corners of the boat
and toss the weighted end over the transom. The rest of the drogue
will snake right out of the box. Retrieval is more complicated and
time consuming, but I do have a windlass installed in the cockpit to
help.

Ko Olina, Hi
Phil:
At the end of this email is the proposal I received from Ace Sailmakers.
Unless someone responds to this posting telling me I'm crazy, I'm go with
this proposal. My guess is that it is the same as what was made for your
boat (Flat Earth). My boat is heavier, with greater windage, but I've
convinced myself this will be adequate. Dave, at Ace Sailmakers, mentioned
that he had made seven of these for heavier trawlers, including one for the
Dashews (http://www.setsail.com/s_logs/dashew/dashew311.html).
Several people have suggested having different types of drogues for
different conditions, but I'm going to just do this one. It isn't my style
to make a passage unless it is "the best month, and the best possible
forecast from the weather router." I'm also a warm water kind of guy. Thus,
I have zero interest in the extreme northern or southern latitudes. Even
with this, I'm sure I'll get caught in seriously ugly conditions sooner or
later, but hopefully can mitigate this through careful route selection,
picking the right months and a good weather router.

PS to Ron Rogers.. I agree with your comment about windage being more a
factor than displacement. I've been asked on many occasions to contrast the
68 with our (former) Nordhavn 62. I've been consistent in saying that the 68
will be infinitely more comfortable, but there will be MANY days when I wish
I had back that nice low profile of the 62.
PSPS Thank you to everyone on the list for the invaluable feedback, and
especially to whoever posted the 888 page Coast Guard manual. A lot of great
information there.
Hi Ken
here's a recent quote for standard 250 cone drogue using nylon double
braid:

Hi Ivor,
A beautiful yacht, congratulations.
for 60 tons loaded displacement:
A: Version A: 250 cones on approx 480' rode
Approx 170' of 1" nylon double braid, tapering
to approx 185' 3/4" nylon double braid tapering
to 1/2" nylon for the last 125'/approx 75 cones
on last section.
Approx 110 lbs for drogue itself (not bridle legs)
Approx 20" x 20" x 26" volume
$XXXX plus bridle legs, if desired, plus shipping/handling.
VERSION B: Using Spectra braid, as we did for Steve
Dashew's power yacht, will cut weight in half, and
reduce volume. Bridle legs could also be Spectra.
I can quote if desired. Line is much more expensive,
and it is much more labor to install cones.
Thanks,
