We have a parachute type sea anchor, but have never been in a place
where we could try it out without the fear that it would be run over
by another boat.

I have one (a Para-tech sea anchor) on each of my powerboats and
wouldn't go out on Lake Superior without one. Sailboats can do things
when things go wrong that powerboats cannot. Mine both assume a broach
position as soon as the power shuts off.

Watched "The Perfect Storm" a couple weeks ago and kept thinking how they'd
be dead in a minute if the engine quit. Certainly cured me of any desire to
be out in serious weather in a power boat, at least a single engine unit.
Seems like drogues and sea anchors are even more important on power boats.
Don't read those magazines so I wonder what they say?

===============================================

What you say is true in my opinion but you are less likely to be
"caught out" in a power boat unless you have a true long range cruiser
like a Nordhaven, Willard or similar.

Power boats have the advantage of speed which gets you back into port
quicker if need be, and they also have a finite range which usually
limits time at sea to a more predictable weather window.

With a power boat you sure have the speed to get home quickly. But
suppose you have engine failure and don´t want to drift ashore. And
water is too deep to anchor.

That's a quandry for sure, but except for the most hostile coast lines
there is usually a zone of water shallow enough that your anchor can
grab. If not, you assume the nuclear attack position and kiss it
goodbye.

No continental shelf at all? Never realized that, guess I'll have to

having a decent inlet or harbor every 20 to 50 miles, sometimes less.

I met a couple last summer who had cruised south from the Pacific NW
to the Panama Canal in a Nordhavn trawler. They only stopped a couple
of times.

Plenty of shelf, plenty of wave action, thick fog, onshore wind, many

headed out. :-)

The trouble comes when you lose power. I wrote an article for
"Soundings" two years ago about a guy on Lake Superior who lost one
engine on a Bayliner 39' due to an injector problem and his shaft broke
and dropped out of the other, causing a bit of water to come into the
boat. He had no plugs and was in the bilge trying to pound gardener's
knee pads into the hole to keep from sinking when he broached in 8'
waves. His antenna mounts broke, his wife (on shore) had the handheld
VHF and water was coming over the gunwales as it flopped form side to side.

The wife called the USCG, who came out and rescued him. They confirmed
the sea conditions when I interviewed them.

This was a classic sea achor situation. He has one now.

Hi
Got both. However the problem I see is a significant misunderstanding
on when to use either. I suggest reading Heavy Weather Tactics Using
Sea Anchors & Drogues by E.Hinz as a start.

Read around and most credible sources and authors, including Larry
Pardey, can't even agree on a common definition of either let alone
when either should be deployed. Very confusing at best.
However.............

My first experience with bow deployed "parachute" type sea anchors
was 1981. I was on an 80 foot Japanese catcherboat part of their high
seas salmon gillnet fleet. The fleet worked the north and west pacific
and also moved into the Bering. There were 50 catcher boats per mother
ship with three mother ship fleets. Big operation. When the weather
kicked up the catcher boats deployed a huge parachute off the bow to
maintain station. There was a swivel attached on the parachute where
the 5 inch plated hawser was also attached. It took about 3-5 guys to
deploy and retrieve. I can still remember that big hawser go rod tight
and watch the water literally explode out of it. Lots of force
involved.

It worked great in 30' seas and 40-50 knot wind. Only drifted about
1.5 knots. I asked the Sendo if he would use the parachute in greater
conditions. His eyes got big and said no. Too dangerous! I never could
understand why the Americans did not use or even discuss sea anchors at
that time. However, there is some great advice in an old Night's
Modern Seamanship book. Check out the section titled small boat
handling in breaking seas and landing boats through beach surf. Good
advice on the use of unitary drogues. I guess people have forgotten the
old ways of doing things.

The current issue of Cruising World has a couple of articles on drogues and
parachute type sea anchors. One article categorically states that these
devices should always be deployed from the stern. The next article is
written by a fellow who successfully deployed a parachute drogue from the
bow while crossing the Gulf Stream in a blow. I think the Pardeys recommend
a parachute from the bow adjusted to keep waves at some angle to the bow
rather than dead on. Techniques must vary with different styles of boat and
condition.

Yes, I would agree. I was just commenting that if you do get caught out you
really are dependant on that engine (and your mechanic).

This discussion reminds me of another story I read once. This fellow in
Florida had a Cigarette-type boat that he used to zip over to the Bahamas
frequently. At normal cruising speed he got decent fuel mileage and got
there pretty quickly. One day a storm blew up when he was half way back.
He had to reduce speed a lot. His fuel consumption went way up. As the
waves got higher and higher he was sweating bullets wondering if he was
going to make it back before his fuel ran out. I think he had his family
along. He made it back and decided to pay closer attention to weather
reports in the future.

parachutes & drogues
 

Yes, there is conflicting advice. For example, Hinz in his book titled
Sea-Anchors and Drogues defines drogues as STERN deployed devices and
sea anchors are PARACHUTE devices deployed from the BOW. Even the
people who manufacture Para-Anchor sea anchors refer to their product
as a bow deployed parachute device.

BUT, in Pardey's book titled, Storm Tactics Handbook, fifth printing
2002, page 15 he states, "Further more, the use of large drogues such
as par-anchors is undergoing an evolution.... And later mentions,
"... heaving-to and parachute drogue usage...." Pardey clearly
believes that a DROGUE is a PARACHUTE deployed from the bow. Apparently
one of the few who do.

Two authorities that can't agree on a simple definition for "sea
anchor. " Very confusing for use who are trying to be safer and more
skilled. Who should we believe?

Interestingly, Hinz describes Pardey's heaving-to bow deployed
strategy. Yet, the opposite is not true. Look as closely as you want
but you'll not find a mention of Hinz in Pardey's book. I wonder
why? Maybe not enough room in his book after Larry Pardey included that
revealing full body picture of himself sporting only a jockstrap and
his sagging ball sack. Now that was a waste of good paper.

Another clue about Larry Pardey's maritime philosophy was a reveling
comment by his wife Lin Pardey. On page 79 she mentioned that his old
school approach does not allow him to consider a scientific approach to
problem solving. For example, Pardey's view of tank testing models.
She says, "Larry who readily admits to being anachronistic, ...feels
tank testing, in itself, proves little. It's too controlled...."
And believes that the only true test of equipment and tactics is by
sailors who use them. In other words, "darn, that did not work. Next
victim......err... uh, I mean next subject please." I'd hate to
have Pardey in charge of the space shuttle program. It would be a
flaming blood bath.

So what is the best way to handle heavy weather? I would start with the
Hinz' books published by Cornel Maritime Press. Later after you learn
a little, look at Pardey's book they had to "self publish."
Pardey takes a whole book to simply say heave-to using a parachute off
the bow. Actually, after reading the Hinz book the only thing needed to
understand Pardey's tactic would be a simple diagram and 50 a word
description. But hey, gotta Pardey credit for trying to make a living.
Anything that keeps people sailing is okay in my book.

One thing I do advise strongly.......... Just don't go out and buy
some gizmo and think it will make you safer. Be a critical consumer of
advice and then practice-practice-practice.

Yea, I know that Pardey has 40 years experience sailing. But maybe
he's only been doing the stuff he learned in his first year 40 times.

What do I do? I use the right tool for the intended job. No single
strategy will work for all conditions.

The other thing I wonder about the Pardey's advice : is it based only on
experiences with their own boats? Sounds like it probably is. Now who
sails in a boat like Taleisin? Saw a recent picture of it in Cruising World
tied up to a wall for bottom work. Full keel from stem to stern. Heavy
displacement. Barn door rudder.
Not much like the boats most of us sail in.

The Dashews also have a book on storm tactics. Fairly expensive. Deals
with current designs I believe.

==========================

Avoid it like the plague.

Plan your route, time of passage and weather window to give you the
best possible odds of having no heavy weather at all.

For what it's worth the folks who make the "Galerider", whom I know
well, maintain that it is designed for deployment at the stern as an
aide to running off downwind. Based on my own experience in small
sailboats, running off is a perfectly fine tactic as long as you have
some sea room to use up. The stern drogue can help you slow down,
thus using less sea room, and can also help avert a pitchpole or
broach if overtaken by a large breaking sea.

parachutes & drogues
 

Most humbly agree.

Okay, so what is a progressively measured response to progressively
deteriorating weather.

Step 1: Do as you said. Plan and avoid like the plague.
Step 2: ??
Step 3: ??

Right on about the "Galerider." Got one. Works great for what it was
designed to accomplish. This discussion got my interest up again so I
thumbed through my Nights Modern Seamanship 1943 edition. There is a
stern deployed drogue in the book that looks strikingly similar to the
Galerider design. I guess if it works it works. Why reinvent the wheel.
The book also has a great discussion that echoes your comments.

Interesting that Pardey is adamant about NOT running with the sea while
towing a "Galerider" type drogue. Pardey says its not a good idea
because you might run into something; like a continent. So he simply
dismisses the whole idea of running free or running with a drogue. Go
figure. I have used it with great success. Never used it to cross a bar
though. Always followed your advice.. avoid such situations like the
plague. Better hang out a day or so till conditions improve.

For my money, I'd get a series drogue: A number of small drogues on one
line that seemed to work better in the CG tests a decade or so ago.

We have a rare option: we can unship the rudder to keep it from getting
banged up if we deploy off the bow.

Still, the best way to handle bad weather is to be elsewhere.

You may be interested in the December issue of Cruising World. There is a
pretty good article by Beth Leonard / Evans Starzinger on their use of the
Gailrider drogue. They use it to keep boat speed in the 5-7 knot range and
to keep the stern of the boat directly into oncoming waves. They use twice
the length of rode recommended by Gailrider and use a bridle to position the
drogue in the center. Some good information on other aspects of drogue use.

Never used one for real in a full storm, but years ago did experiment
to devise tactics & found them all but useless if not outright dangerous.

The boat will still lay beam on almost no matter how big the sea anchor
is; but in the moderate conditions we tested a 32ft yacht, well offshore
it provided a violent snubbing. No wonder books regularly report they
"fail" & probably it's just a well.

Most boats even high wooded motor boats, are safest just left alone to
lie a hull in all but the most extreme conditions & after that to turn &
run is about all that's left; then & only then in my view would a sea
anchor be of some use just to slow you, also the saloon carpet or a sail
laced to the line slightly aft will stop any breaking water reaching you.

I don't have either, or any practical opinions about how to use them.
However, the December Cruising World has several relevant articles and
some references.

Much as I love surfing, the steering can get tiring in the big stuff.
I can imagine offshore conditions where I would welcome some drag to
work against the stern spinning out, especially if I had already had
enough fun.

Hi K

Read the book titled Sea-Anchors and Drogues by Hinz. Your frustrating
experiences are described in the book and are a common reason why
people get frustrated and abandon the sea anchors and drogue idea. The
problems you described are remedied easily.

But then again, you may never have a reason to use those tools.

Thanks for that Bob I'll have a snoop. It's been my experience that the
difficulties are bad enough when the conditions are tolerable, but I'd
be worried in a real situation.

However I take your point & will do some reading, thanks again

What would someone recommend for a 23' sailboat with a dory bow,
tumbleholme stern, 9' beam and a long, straight keel drawing about 4
feet. (not a fin type). I have an 8' surplus cargo chute but from what
I've read you need to carry 600 feet of line to deploy in 20 foot
seas. Not really an option for most small boats. I tried a similar
setup in a different boat but there was not enough weather to get an
idea of how it would work. The rudder can't be chained off on this
boat so how do you avoid being wrecked or swamped from the stern if
you run off with a drogue of some sort? Thanks.

My suggestions are;

that on a 23ftr well offshore (as contemplated) where space/weight are
a real issue you could maybe find a way to slow the boat when running.
Experiment in controlled conditions, you'll soon find a setup that suits
you & it might be as simple as dragging a tyre which when in it's cover
can double as a tough fender.

As for the boat a lashed to lee tiller, tie everything down & find
yourself a comfy spot to read. (checking for traffic every once in a
while; I was on a yacht lying a hull in a blow & in the middle of what
we thought was the end of the world a container ship steamed through out
of the gloom, not even bothering to roll:-))

My experience with motor boats is that when they lose power they always
face beam to the seas. Larger boats with deep keels take longer to
assume this position, but they all seem to get there quick enough. Some
say the right wave equal to the beam of the boat will flip it over.
The rule of thumb is a breaking wave one third the beam of the boat is
dangerous. (Heavy Weather Sailing)

Neither of my boats would survive that, and I would probably have just
enough time to deploy the EPIRB and go over the side before they sank.

My understanding of the distinction between drogues and sea anchors is
that drogues go over the stern to keep a sailboat from going too fast
down the face of a wave. Sea anchors are deployed from the bow (from
powerboats anyway) to keep the boat facing the waves in the only
position they can handle big water. The boats only move at 1 - 1.5 knots
in this condition. If I deployed either of my sea anchors from their
respective boats' stern in any kind of seas, they would be pooped and
sink. No one that I've read recommends deployment of a sea anchor from
anyplace other than the bow of a powerboat.

I think drogues and sea anchors are different designs of devices for the
same purpose. You can rig either off the bow or stern or one of the
quarters. To me the drogue is less drag than a sea anchor and serves
more to slow the boat while the sea anchor trys to stop the boat. That
is why drogues are more likely rigged from the stern (to slow the boat)
and sea anchors from the bow (to stop the boat or minimize drift). If
you rig a drogue from the bow you risk damaging the rudder with the
continued backward movement of the boat. If you rig a sea anchor from
the stern you risk waves breaking into the cockpit of the stationary boat.

The sea anchor has to be big enough to stop the boat and hold it facing
the waves. This takes a huge parachute. It is hooked to your ground
tackle and you may need 300' of rode. Having some chain in there to
provide a catenary effect is recommended. And you have to continually
watch for chafing. This process involves considerable stress on the
point the rode connects to the boat. One needs to be able to add a
little length (you probably aren't going to be shortening it any) and
have old fire hose, rags or something else where the rode meets the
fairleads, hawsehole, or whatever.

The Jordan series drogue seems to be the hot setup these days.

And if you pay attention to the weather and nothing fails on your boat,
you've wasted the cost of the sea anchor, just like all that money
you've spent on insurance over the years. The only real difference is

parachutes & drogues
 

My experience with motor boats is that when they lose power they always
face beam to the seas. Larger boats with deep keels take longer to
assume this position, but they all seem to get there quick enough. Some
say the right wave equal to the beam of the boat will flip it over.
Neither of my boats would survive that, and I would probably have just
enough time to deploy the EPIRB and go over the side before they sank.

My understanding of the distinction between drogues and sea anchors is
that drogues go over the stern to keep a sailboat from going too fast
down the face of a wave. Sea anchors are deployed from the bow (from
powerboats anyway) to keep the boat facing the waves in the only
position they can handle big water. The boats only move at 1 - 1.5 knots
in this condition. If I deployed either of my sea anchors from their
respective boats' stern in any kind of seas, they would be pooped and
sink. No one that I've read recommends deployment of a sea anchor from
anyplace other than the bow of a powerboat.

The sea anchor has to be big enough to stop the boat and hold it facing
the waves. This takes a huge parachute. It is hooked to your ground
tackle and you may need 300' of rode. Having some chain in there to
provide a catenary effect is recommended. And you have to continually
watch for chafing. This process involves considerable stress on the
point the rode connects to the boat. One needs to be able to add a
little length (you probably aren't going to be shortening it any) and
have old fire hose, rags or something else where the rode meets the
fairleads, hawsehole, or whatever.

And if you pay attention to the weather and nothing fails on your boat,
you've wasted the cost of the sea anchor, just like all that money
you've spent on insurance over the years. The only real difference is
that if the **** really hits the fan and you really need this device,
you get to collect instead of your beneficiaries.
