weather strategies.
Galerider Drogue (2005)
Question: I heard that
you had good success heaving-to on
Morgan’s Cloud using a Galerider
drogue off the bow. What were the
details?
Answer:
Here are the details I compiled for
the Drag Device Data Base:
Vessel: Morgan's Cloud
McCurdy & Rhodes custom 56 cutter
LOA 56' LWL 42'
Beam 15' Disp 56,000lbs
Draft 6.5'
General description: A moderate
displacement long fin keel cutter with
fine ends and moderate overhangs.
Rudder is skeg hung. I have owned
Morgan's Cloud for 12 years and
sailed about 80,000 miles in her, much
of it in the high latitudes including
three trips to Greenland and three
trans-Atlantics. Like all of Jim
McCurdy's boats, she is exceptionally
sea worthy with an easy and soft
motion. She heaves-to well, and this
is our standard heavy weather tactic.
Phyllis and I were
on a passage from Bermuda to the
Caribbean in January of 2000. We left
Bermuda on January 12th. In the early
hours of 15th January we were
overtaken by a cold front driven by an
exceptionally powerful high pressure
system of some 1040 MB. The front
itself was quite benign but as the
high moved in the pressure gradient
got steeper quickly and by 0800 it
was blowing full gale with the seas
building.
We ran all day before the gale with
winds steadily over 32 knots, peaking
at 46 knots. By 1600 the seas had
built to the point that the autopilot
was having trouble steering and so we
decided to heave-to, which we duly did
under triple reefed main at 23°16'N, 64°34'W.
At about 2300 we were hit hard on the
weather beam by a breaking wave that
heeled the boat to 30 to 40
degrees. At this point the significant
wave height was about 20' (verified by
weather fax chart from Boston) with
some waves higher. In addition the
wave train was becoming confused and
breaking.
We had not been hit that hard ever
before and I believe it was caused by
the extreme variability of the wind in
this high pressure-driven gale.
Vertical instability in a high causes
much more gusting than in a low and in
our case the wind was varying from 25
to 46 knots.
The lulls would allow the boat's bow
to fall off and then in the next puff
she would reach off at as much as 2
knots before the action of the rudder
lashed hard down would bring her back
up to about 60 degrees off the
wind—her normal heave-to attitude. It
was during this reaching off cycle
that she was vulnerable to breaking
seas.
I did not wish to run off since I felt
that even with a drogue, this would
have required hand steering in the
confused seas, which would have
quickly tired Phyllis and I.
After watching what was happening for
about 15 minutes I deployed our 42"
Galerider on 250' of 7/8” nylon double
braid line from the weather bow, while
still heaved-to. This was quite easy
to do despite the fact that it was
blowing hard enough to make it
difficult to stand on deck. I slid the
Galerider down the weather bow with
the wind holding it against the hull.
Once in the water I paid out the full
250' and cleated off. The line was led
through a fully enclosed and very well
rounded closed fair lead about 2' back
from the tip of the bow.
The effect was immediate and dramatic.
Our fore-reaching slowed from
.75 to 2 knots to .3 to .75 knots and I
suspect much of that was false reading
due to the motion of the bow. The bow
stayed at 50 to 60 degrees from the true
wind with no tendency to fall off
further. The drogue line made an angle
of about 130 degrees from the bow of
the boat so that the Galerider was in
the water behind and to windward of
the boat. In the morning I was even
able to see it from time to time in
the front of the larger waves. It
showed no tendency to break out of the
wave, or to tumble in a breaking wave.
We stayed heaved-to like this until
the following afternoon, when the wind
moderated, and received no further
wave strikes.
The interesting thing was that the
Galerider deployment line was not that
heavily loaded and was frequently a
bit slack. The highest load came when
she was hit by a big gust after a long
lull, but even then I would estimate
the load as no more than that on an
anchor rode in a strong breeze. She
showed no tendency to tack through the
eye of the wind, despite having no
sail up in the fore triangle. Both the
jib topsail and staysail are on roller
furlers and so provide quite a lot of
windage forward.
Recovery was easy, using our electric
windlass, and was done while still
heaved-to, when the wind was still
blowing near gale.
In summary, this was not by any
stretch a survival storm for a boat
our size, but was certainly a full
gale with mature and perhaps dangerous
seas. The same blow caused havoc in
much of the northeast Caribbean,
driving a freighter on to the beach at
St. Maartin and reversing the trade
winds as far south as St. Lucia.
Deployment of the Galerider in this
way was easy, the motion comfortable
and recovery equally easy. It
significantly extended the safe range
for heaving-to.
In future I think I might extend the
rode to 500' since this would make
sure it was not on the same wave as
the boat and reduce any chance of it
being tumbled at the wrong moment (not
that this happened).
Sea Anchor (2004)
Question: What is your
thinking on sea anchors and do you
carry one on Morgan’s Cloud?
Answer:
Sea anchors, a very big subject! First
off you should know that I have never
used one, so this is all theory. Our
normal gale strategy is to heave-to.
We have used a Galerider drogue off
the bow to slow fore-reaching and keep
her head up to the wind in gusty
conditions. Yes, I know one is not
supposed to use the Galerider this
way, but it worked great for 24 hours
in a gale south of Bermuda in January
2000 (see above for more information).
We carry a sea anchor for three
reasons:
-
To lie to if the conditions get too
dangerous to heave-to, due to
breaking waves. The standard wisdom
in such conditions is to run off but
I have reservations about that,
particularly the danger of broaching
and the requirement to steer. When
short handed I really think it is
important not to have to steer since
it will quickly exhaust the whole
crew, particularly in cold
conditions.
-
If caught on a lee shore, since the
sea anchor will cut drift to much
less than heaved-to.
-
If we lost the mast in storm
conditions.
As to rigging, I think it must be HUGE
and that the devil is in the details.
Our rig is sized for a safe working
load of 7,000lb and breaking load of
three times that. We went to a great
deal of trouble to make sure that
there were no weak links. To this end
we installed a special pad eye
through-bolted with back up plate on
the fore deck; the largest eye Harken
make.
From there the rig is as follows:
-
Pad eye.
-
6' of 7/16” G4 chain, to take chafe,
led over the anchor roller, fastened
with high tensile 1/2" galvanized
shackles. (We think stainless is too
brittle). The chain is retained from
jumping the roller by a 1/2" bolt.
-
50' 1" nylon double braid rope
pigtail led aft outside lifelines so
that rig can be deployed from the
aft deck.
-
250' 1" nylon double braid rope.
-
350' 1" nylon double braid rope.
-
24' sea anchor.
The rode is in two pieces simply
because it would be too heavy to
handle in one. Each piece has spliced
eyes on each end with a massive deep
thimble in them and they are connected
using 3/4" galvanized shackles.
Contrary to some recommendations, I do
not think that more chain in the
system would add any value. The idea
that it will help to hold the boat’s
head up in storm conditions is, I
think, wrong. In addition, more chain
will make deployment much more
difficult and recovery down right
dangerous.
Talking of recovery, we are rigged
with a partial trip line to a float,
however I have real reservations about
whether Phyllis and I would be able to
get this rig back on deck,
particularly after enduring several
days of survival conditions, and in a
left over sea. I suspect that we might
have to cut it away, but since it is
our final line of defense and not our
normal heavy weather strategy, we are
resigned to that even though it means
cutting away $2000+ worth of gear.
We are also rigged so that there is a
short nylon tail led from the joining
point of the chafe chain to a forward
cleat so that the chain just acts as a
safety but the nylon takes the load
and gives us a fair lead from the bow
if used with a "Pardey Bridle". (See
Storm Tactics by Lin & Larry Pardey,
www.landlpardey.com).
I am not sure if the "Pardey Bridle"
would really work in storm conditions
on a boat of your or our weight, but
it is worth trying since it would be
so much more comfortable.
Update, 05/2007:
For a number of reasons that we will
discuss in a future
Blog, we have sold
our sea anchor and purchased a Jordan
Series Drogue.
