Not wanting to be found
 
Here is a hypothetical question:

If somebody on a sailboat did NOT want to be found and had a 36 hour
head start leaving someplace like say the N. Florida Gulf coast, how
difficult would it be to find him. I assume the sailor not wanting to
be found could take some measures such as painting his boat a grey
color to match the water or even paint his sails, not use lights at
night, etc. What else can you think of to minimize his chances of
being found.
How difficult would it be in this case for conventional SAR to find
him? Remember, every 36 hours, the necesary search area quadruples
until after a few days it covers the entire Gulf of Mexico and its
shoreline.
I think it might be possible for such a sailor to elude being found for
a long time.

Its much easier to camp out in the park as a homeless person across the
street from the police station. They would never look there. Or, go buy
a car out of the paper with ligit bill of sale on Friday. In 36 hrs,
you could be at the Canada or Mexico border. Go camping. Now if your
just getting away from the wife, I understand. Sailing sounds good.

I assume it's a small sailboat and doesn't carry a radar reflector.



Glenn Ashmore January 13th 05 09:30 PM

About 15 minutes, if the time and point of depatrure are known. There would
be several radars and patrol planes tracking his every move to see if he
turned towards Cuba.

Fill the boat with cocaine. We seem to have a hard time finding that

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

I don't think that matters anymore with a decent modern radar unit.
My new 4 KW Furuno routinely picks up small sailboats that are 4 or 5
miles away. Parts of the Gulf are just littered with crab and shrimp
boats however and you'd blend in with them on the radar. With your
sails down you'd be difficult to spot by eye from more than 2 or 3
miles away.

This depends entirely on who is looking. If the CG wants to find you,
they will track you from the beginning of the trip and the color of
the boat or whatever won't make any difference.

If the person can avoid being a person of interest to homeland
security or the CG so that neither of them has an interest in looking
for the person, then there's no need to take any special precautions

Probably the best thing to do would be to set off as if it was an
ordinary trip, say from Texas to Pensacola on the ICW, and file a
float plan with someone to that effect. Tell them if you don't turn
up in Pensacola in 2 weeks, to start to look. Then go the other
direction.

Unfortunately, my life is not interesting enough for anybody to look
for me. The question is purely hypothetical as I am wondering if Low
Tech could win over High Tech. Concerning tracking by the CG, how
would the CG find him in the first place if all they knew was that he
had departed sometime in th elast 36 hours from a certain port? They
might use radar but I understand that many small sailboats show up
poorly on Radar. They might use visual search methods but that should
be easy to defeat. Specifically, how would the CG find him?
Concerning radar, I admit my ignorance of anything but theoretical
concepts as I have never used one. Would removal of metal lifelines
reduce the radar cross section? Removing the mast would be difficult
but I think it produces a minimal return anyway being rounded. Would
covering the engine with a "space blanket" (aluminized mylar) reduce
its radar cross section?

Sailboats do show up on radar, but this is a 'line of sight' thing (if
I am correct) and so they'd have to be near enough to be seen. Most
searches are done from the air IME, unless they already know where you
are. You can cover a whole lot more ground from the air. It's hard
to find a small object (i.e. a person or life raft) but a boat is a
bit bigger. I don't think any of those options would work well enough
to be worth the trouble.

My daughters BIL and his half brother took off from Miami to go to the
Bahamas at night in their boat (i.e. my SIL and his brother's boat)
and the CG stopped them suspecting drug running. Although the CG let
them proceed, they were tracking them (fortunately) so when they ran
aground on a uncharted rock so violently that the rocks came up
through the sole of the boat, breaking the BIL's neck, wrist and
severing an achilles tendon, they were able to get to them quite
quickly when they made a Mayday call on the VHF.

The sailor has to come to port sometime, someplace. That's when they
would be caught.

In the mid -80s, i worked for a defense contractor. We heard budget
cuts were coming and were instructed to be on the lookout for civilian
applications of our work. One guy whose specialty was figuring ways to
reduce radar cross sections of things moaned to me that no civilian
would be interested in his work. I told him that if he could figger a
way to really reduce the radar cross section of a DC-3, I was sure I
could find some Columbian "Entrpreneurs" who would pay a lot for it.
He gave me a blank look at first and then said "Thats not funny". I
thought it was.

D.B. Cooper January 15th 05 03:39 AM

Hahaha... what are you doing.. smuggling drugz..? They're the only people in that region of water
that don't really want to be found.

"Hypothetically" you'd have to take under consideration all types of radar (military ones pick out
small boats without much problem due to the different wavelengths of radar they use), SAR (Synthetic
Aperature Radar), infrared heat signature (hot engines flare brightly on sensor displays against the
cold black ocean).

Emission Control (EMCON) you'd have to ensure that you do not transmit anything by radio, turn off
your radar, cell phone, etc.

Since stealth technology is generally priced out of range for the average person, it helps by
removing the radar reflector. Greenpeace did this in the early 1980's and while keeping radio
silent, managed to sneak up and penetrate over 350 km into a restricted region in the south Pacific
that the French used to test nuclear bombs. They got close enough to the test site to see the bomb
suspended under the balloon. The moment they hoisted their reflector, their presence was detected
and the French navy reacted fast (and brutally).

I'm not sure how to use visual camoflauge.. perhaps to reduce visual detection by other ships would
be to paint the hull and sails a dull light gray. The "go-fasts" that regularly run that region are
painted black or dark green and operated at night for the most part. They use speed as their
primary way of avoiding interception.

Sail due east for a while then angle south. Unfortunately, OTHR (over the horizon radar) which can
accurately measure wave height and direction accurately works pretty well at detecting vessels of
around 10 metres in length and larger from over a thousand miles regardless of the hull material.
And there are at least two stations that provide blanket coverage of that particular region.

Hopefully a random search by regular drug interdiction patrol units in the south Gulf area won't
stumble upon the person. That is one of the most heavily surveilled areas of the USA and it
surprises me that people manage to get thru undetected. (actually many are detected but they are
unable to intercept). In the end, a certain amount of luck is required. And hopefully, no one will
call in a sighting when an "APB" goes out for such-and-such person and a sailboat matching some
description.

You'd better. I hope that the Homeland Security and the FBI see it that
way. I happen to know that they monitor alot of these newsgroups
including this one.

Really,

Elegant solutions to not being found? To what end?

Would
covering the entire boat with an aluminized "space blanket" with no
exposed edges or folds reduce the radar cross section much?


Why? Most folks waht their boat to be visable. What is your point?

I assume
the metal shrouds produce significant radar return so they are a
problem unless he somehow replaced them.


Actually, shrouds and masts produce very poor returns. They tend to
disperse the radar signal. Hence the use of radar reflectors.

We can assume that he either
doesnt run his engine or that he floods his cockpit partway to hide the
engine IR signature.


Just fill the cockpit with the drugs.

Go fast boats are probably easier to see than a small sailboat as their
power output is so high.


I guess. So what are you trying to run away from?



Paul Schilter January 15th 05 08:32 PM


dbohara,
This is funny, if you used the space blanket with the reflective side
out you'd light up like a bulb on the radar screen. I believe stealth
technology is based on absorbing the energy and then having acute angles
on the surface so the reflection that is left is diverted away. Floods
his cockpit? I don't think the engines would like this. The solution is
LEAD!!! Construct the whole boat of LEAD!!! :-)

This answer is PURELY HYPOTHETIC.

Covering a hull with aluminum foil would increase its radar
cross-section from quite a lot to an awful lot.

This is funny, if you used the space blanket with the reflective side out
you'd light up like a bulb on the radar screen. I believe stealth
technology is based on absorbing the energy and then having acute angles
on the surface so the reflection that is left is diverted away. Floods his
cockpit? I don't think the engines would like this. The solution is
LEAD!!! Construct the whole boat of LEAD!!! :-)

IMO, how easy it would or wouldn't be to just disappear depends on the
circumstances. If you're a fugitive being sought, it might not be that
easy...but if you're someone who just wants to escape his life, it
should be very easy. Just buy a boat without telling anyone...tell your
friends and family that you have to go to Chicago, St, Louis,
Paris--anywhere but out to sea--for a week...set sail instead...giving
you at least a week's head start in a direction no one would ever look
in...and even when they do think of checking on your boat--the one
everyone knows you own--it'll still be in her slip. You could be
anywhere in the world before anyone figured out how or when you left, or
which direction to look. By then you've grown a beard, dyed your hair,
lost 20 lbs...the only thing that might give away your location is any
record of the places in which you've had to show your passport. But if
you're REALLY determined to disappear, it's not that hard these days to
get a new passport under a new name. Unless you're a fugitive, no one
would ever have any reason to question its legitimacy.

The only real issue would be money...but anyone planning such a move
should be smart enough to quietly start transferring funds to an
offshore account in an untraceable manner (convert to cash, deposit only
that cash to offshore account) months or even years ahead of time.

IOW, anyone who really wants to disappear can do it with some planning.

Your name January 16th 05 03:39 PM

It is really quite simple and low-tech. You can guarantee you will not
be found only if you are not there!

Go out, sink the boat, come back in, and go anywhere but where they will
be searching for you.

Or, go out, turn around, and return to port well before the 36 hours.
Eventually the boat will be found, but that will only mean that at some
point in time you were somewhere in the world. Not very much to go on.

If you have trouble with this answer, I think you have some other
agenda. True, someone might want to disappear. But you've posed a
problem in which someone wants to disappear using an empty gum wrapper,
yesterday's newspaper, and a half-eaten bagel on a day when the
temperature is over 72 degrees! And then you want to discuss at length
the reflective properties of foil-backed gum wrappers?

If your question were strictly technical, the "disappearing" scenario
would be superfluous since you could just ask about visual and radar
detection of various hull signatures.

I though the OP was referring to a sailboat. One could
close the scuppers and flood the cockpit, but I don;t know what
it would accomplish. Water would slosh around and enter via cockpit lockers.
I don't know, this thread is silly anyway.

OK, I confess, I am really trying to hide the nuke I built from
hundreds of old smoke detectors and parts from a '72 Camaro.
The Purpose of flooding the cockpit while running the engine is to put
a low temp high mass object 'tween you and any IR detector.
As far as the aluminized space blanket for Radar, generally, it is
edges and corners that produce the large radar return. 90 degree
angles particularly make good returns which is why a tiny radar
refelctor will give a much better return than most sailboats. A very
large sphere (the size of your boat) will give less return than a 10"
corner reflector. The purpose of the space blanket is to mask the
edges and corners from things like the engine, the toerail,
chainplates, etc. A space blanket with no sharp edges covering the
sailboat should give less return than your average sailboat. I once
took a course in radar theory but I know nothing of ANY practical
application.

Of course the ultimate way to disappear and not be found, would be to
drown.

I suppose it might be possible to simulate that by setting off in a
boat and then wrecking it and leaving the wreckage while actually
getting to shore and buying another boat and taking off from there.

But the OP was really asking whether you could conceal a boat in the
ocean by using low tech methods so that high tech methods could not
find you. And my answer is - it's a whole lot easier not to be found
if no one is looking.

You actually hit upon the best solution: hide in plain sight. A touch
of plastic surgery, an industrial "accident" that obscures your
fingerprints, a few grand for the "pro" falsified documents, and then
hide in plain sight. The boat itself should be a Catalina 30...they
are common as muck as my British relatives say.

Here is a hypothetical question:

If somebody on a sailboat did NOT want to be found and had a 36 hour
head start leaving someplace like say the N. Florida Gulf coast, how
difficult would it be to find him. I assume the sailor not wanting to
be found could take some measures such as painting his boat a grey
color to match the water or even paint his sails, not use lights at
night, etc. What else can you think of to minimize his chances of
being found.
How difficult would it be in this case for conventional SAR to find
him? Remember, every 36 hours, the necesary search area quadruples
until after a few days it covers the entire Gulf of Mexico and its
shoreline.
I think it might be possible for such a sailor to elude being found for
a long time.


Some years ago there was a cruise ship high jacked in the weastern
Atlantic. It took days before the authoritries could find it. Anyone
remember that one?
