AI Thread Summary
Survival on a deserted island requires immediate focus on finding fresh water, as it is the most critical resource. Building a shelter should follow closely, using natural materials and tools available. Food sources, including fruits, berries, and game, must be identified, while avoiding anything washed ashore. Establishing sanitation practices is essential for health, and a leadership structure can help maintain morale and organization among the group. Long-term survival strategies may include creating signal fires and exploring the island for resources.

A group of ten to twenty people are ship wrecked on a desert island, they
have basic hand tools and food and water that will last for two days, no
one knows they survived the ship wreck, so no chance of rescue.

Physics news on Phys.org
Last man standing dines well?
 
First build shelter.
find a source of fresh water, if you can't find water, make water traps, collected from organic matters{Watch Voyage of the MIMI}.
Then look for food, never eat anything washed up on shore. Look for fruits and berries.
Make and maintain fires
explore the island..then go have drinks at the resort on the other side. :smile:

Sorry Hypatia, but there is no resort on the side, if you knew that it could
be years before being rescued, if ever, what things would you have to make?
what about clothing, hygene, medical supplys etc.
 
well clothing would be optional, at that point, who cares? But I do know how to make palm leaf hats.
Sanitary needs...pits dug a goodly distance from where your shelter is, you can even lay 2 logs on the edge and a make a seat. Put a little sand on top after each use.
Bathing is done with sand in the ocean.
Cuts and bruises and bumps, go directly into the ocean. To bring down fevers, I would also toss you into the drink, or cover you with mud.{keeping in mind the 4 basics of medicen, hot, cold, wet, dry}
Mud also works well to keep bugs off of you. And mixed with a sweet sap, will help sun burns, rashes.
I would start experimenting with different plants/roots and inner tree barks.
 
They should cut all the trees!
 
No matter where this island was, the first priority would be sorting out a source of clean water, although how this was done would depend on the location, resources, and circumstances. Secondly, if stranded in a group (as we are), a leadership system needs to be agreed, with attention paid to morale, discipline, distribution of expertise/ability, and possibly rationing. Loss of morale is one of the biggest indirect killers in these situations. Then we can start to think about things like sanitation (a latrine at least 3 metres deep, at least 500m away, and at least 100m downstream of any point on a river where water is taken from), and food and shelter (again, highly dependent on the environment).

Always been a bit of a survival geek, and have spent many weekends away living off the land, so to speak.
 
But without shade or cloths..all your bare necessities would burn :cool:
 
Do we need to play with words to get the answer? :confused:

After a few months I would be paying some mind to the stars/moon, wind direction, and make currant buoys, and start plotting seasonal shifts. Days of the week would no longer matter, but monthly cycles, will let you know when its time to celebrate hoildays, its good for moral.

I may begin plans to build a sea worthy raft.

Please define basic hand tools. Does that include hatchet? Otherwise building things of wood or cutting trees is mighty difficult - although one can build a fire on fallen trunk and do it the way the Islanders did it. Then one could also look for hard and sharp rocks.

Fresh water first. Then half builds shelter and the other half scavenges for food.

Toilet facilities must be well away from freshwater and where fishing is likely.

Any shiny surface or surfaces to flash at passing ships or planes?

Well, if it's a large island, then they should start a fire, and burn the whole forest down. That would send up a large cloud of smoke, which would be visible from the NOAA weather satellites; some geologists or whatever would fly into investigate. In the meantime, they could survive on the barbecued remains of whatever indigenous wildlife used to live there. Also, it would be easier to find any natural water source or spring if there were no trees to block the view.

No just think what you needed to do to stay alive, Brewy has mentioned
electing a leader, and some good points have been raised already, so lets
make life as easy as we can.
 
  • #15
I have found a source of water but it is an 8hr round trip through thick jungle.
 
  • #16
first, find fresh water. this is the most important to survival, food and shelter can wait.
then, build a shelter near the water.
next, find berries and other edible plants, and make traps for game. also, learn to fish, PDQ.
Next, don't do anything stupid.
have signal fires ready to ignite in a visible spot
also, have something to signal a plane with.
one way to test if a plant is poisonous or not is to first, wipe it on your skin and wait. if irritation dosn't occur, then put some on your lip. if you are ok after a while, taste some, if ok, swallow a little bit.
i have never used this, i have had no need to, so it may not work as i said, but it should
also, some plants loose some poisonous qualities if you boil them, but not all.

Ok, we have ten men and ten women, we have some tools, and we know how
to look for food, should we elect a leader? knowing that we may be there for
years what sort of things should we build?
 
  • #18
Is the island flat or does it have mountain/volcano/hills?

Give me the axe and let me get started on the shelter and dugouts. Interim shelters can be simple lean-to's.

Any reptiles/birds? Birds are good food in a pinch.

Certainly fish - spear fishing.

I say make a council,so that no one person dictates to all. Sub groups, will naturally form with personalities, most people know what they are best at.

Ahh good we have a needle, threads can be made from tree/plant fibers.

The island Was volcanic, and has a range of hills , most of the island is jungle
with some grass land.

How do we decide a leader? Who wants to be he or she? will laws be made?

wolram said:

Whoever is holding the axe. :biggrin: just kidding.

Acutally, I favor a democratic process along the lines of communal consensus. I don't see the need for a 'leader'. Presumably people know what needs to be done, and so each can volunteer for whatever job suits his or her ability.

Just let me build boats and do other heavy work. I also like to climb trees and height is not problem for me.

If I was planning an ocean excursion, then I would likely have a cellphone and GPS system with me - in a watertight bag - which I would likely wear.

Otherwise, I would certainly familiarize myself with the star field and position of the sun/moon, and I would refer to a map of the general region. That's just the way I am. I always know where I am - and I navigate by sun, moon and stars.

I would be inclined to campout near the water the first night. Presumably one needs vessels in which to transport water - or do we have such vessels with us? Otherwise we make some.

If there is forest/palms, we use natural shelter of the trees. Or we find a cave/caves.

What kind of trees do we have? Any cocounts?

Are we in the Pacific Ocean?

Besides birds, anything like wild pig or boar?

We have wild boar, and yes let's be in the Pacific, i have not seen cocnuts yet
but there may be some elswhere, and we have to make every thing, we even
need clothing as we were all by the pool when the ship sank, we only had time
to grab the few tools we have.
 
  • #27
If the waters 4 hours away i would suggest drinking lots before you come back to base camp. Either that or just set up camp near the water.
 
  • #28
Well, with wild boar on the island, we'll have to be careful, especially the males and sows with young.

I'd say first camp by the water. Make water vessels if necessary. Make simple shelters. And look nearby for food.

As soon as we feel comfortable that the food and water is supplemented beyond 2 days, then we can start building boats, bigger shelters, plan for a signal tower or two. We certainly need more than two days water supply.

When I start working hard - my calorie intake goes way up. If I am doing heavy labor, I am consuming several thousand calories/day.

I would start looking for traces of boar, finding the trails and setting traps.

This is clearly a dream, as it cannot possibly be real.

Since when does a desert island wooded?

I think the term is deserted island - although lots of folks say desert island. Although it could be a dream and we are on a desserted island with lollipop trees, and streams of chocolate sauce and root beer, and gum drops - sounds like Willy Wonka. :biggrin: :rolleyes:

But seriously.

1. Triage. Check for any wounded (this may not be an issue, but I'm generalizing the scenario). After all, the goal is to maximize survival of the castaways, right?

1. Take stock of assets. (Again, generalizing scenario. What if there's a radio transceiver, or water?)

1. Find shelter. (Don't bother making it, just find something that will get you through the night. Explore the shoreline for X hundred yards in each direction. Do NOT go more than 50 yards into the woods.)

IMO, shelter is a more immediate priority than water. You can survive the night without water. You might niot survive the night if you don't have shelter when a storm comes up. You can't look for shelter after dusk, or you risk getting lost, haviing an accident or worse.

Ideally, all the above will happen simultaneously, as there are 20 people, but that doesn't alter the order of priorities.

2. Find fresh water
3. Find food source
4. As needed:
- explore (shore first, do not wander into woods)
- set up an S.O.S.

Fresh water first. You can sleep wherever there is ground. If a tsunami washes you away during the night, well, tough luck, that goes with being on an island, but if you can't find water in a day or two then you're sure to die. Some tree branches make a bed. Food next. What roots and bark can you boil? If anyone has a pet dog you can put it to good use as a taster. If you're lucky there are berries or fruit; if you were lost where I live, except during a few short days in summer, there are no berries or fruit. Maybe you could eat boiled grass, if there is any grass. Don't forget ants and grubs--those are often easy to find. Hunting might be an option.

I once read a short story by Stephen King wherein a shipwrecked surgeon on an island with nothing to eat cut off his body parts one by one and ate them.
 
  • #34
What if you can't find water?

Collect rainwater:

Collect dew: Tie rags to your ankles and walk in grass and foliage at sunrise. Then wring out the rags and collect the water.

Look for green on any local mountains: Follow vegetation and animal trails to any potential sources.

Catch fish: the eyes, spines, and even the skin contain fresh water. Suck the liquids out of the eyes and spine, and wring out the flesh in a cloth.

Look for bird dropping on rocks: This may indicate that birds congregate around water found in the cracks of the rock.

Locate Banana and plantain trees: Cut down the tree and leave about a one foot stump. Scoop out to form a hollow with a bowl shape. The roots will continually refill the stump with water for about four days.

Whatever you do, never lose your soccerball.

I agree with DaveC, first night, find shelter. We don't know what the climate is on this island. Are we going to be scorched by mid-afternoon sun, or half frozen at night? Either way, until we locate fresh water, we'll need a sheltered place to rest between excursions, and to regroup every so often to determine what progress is made and what still needs to be done.

Though, Wolram has informed us there's a water source about 4 hours away. So, let's get a good night's rest in our temporary shelters the first night and start out at dawn if we're going to move camp. That way we can get there before the afternoon heat hits us. I suggest we send two people ahead of the large group who will walk more quietly to scout out where the wildlife are before the large group scares them off. We can't rely on nuts and berries because we don't know what ones are safe to eat. Unless we come across familiar plants, better to stick with hunting and fishing.

If we're camping near a rare water source, we'll have to be careful of the boars, but that also means our food will come to us. We just need to fashion traps. One option is digging pits.

We may also be able to fashion some rope/twine from the plants or from our clothing, and bend one of those needles into a hook to try fishing. Alternatively, we might be able to make a net to fish along the surf. If we have to walk back 4 hours for fishing, then I'd recommend we assign two people that job (it'll take 2 to drag a net through the water), or we can rotate the task each day. Figure it will take another two hours to catch enough fish to bring back to camp, so they're going to be gone for 10 hours a day. We need to provide them with something to carry water with them. Hopefully we'll have good success with the hunting and won't need to send people on 10 hour trips for fish every day.

So, does anyone know anything about making traps? We might be able to funnel animals toward them if we can put obstructions on either side of a gradually narrowing path toward the traps, then work our way around to the far side and drive anything in that path forward and into the traps. We can't do this too often though, or the animals will catch on. Some days, we should leave the far side of the trap open so they run right through and don't get scared of taking that path of "escape" until we need that meat, and then close the traps.

On our first night, let's go around the group and find out what skills people have. Astronuc has already told us he's good with weilding the axe. As we build more permanent shelters, that'll come in handy. I'm decent at sewing, enough for whatever we're going to need to sew, and I can hold my own with the hand saw and hammer too. I'd rather not play with axes lest I add more to the casualty list, unless it's to use the blade to butcher the animals we catch, which I'm willing to do...I can handle all the butchering, fish cleaning, etc. Okay, who's next?

This is actually an idea worth considering if the island is big enough, we may choose to sacrafice some of the wooded land to try to catch someone's attention. We'd have to control if of course, let's say we choose a spot surrounded by Rivers, Coast, Ridges, or just unwooded land that we could cover up with sand or something to make fire safe.

I vouch for an anarchist system of government, probably based on the Zapatista's model of cousels and multiple leaders. This system would probably be most efficient in groups larger than 20 people but would work well none-the-less.

I can make weapons out of almost anything, so perhaps I would best serve as armourer and hunter. Personally, I have no desire to take on a wild boar with an axe. Some high-power crossbows and/or longbows would be preferable. There should be enough straight pieces of wood available to fashion fire-hardened arrows and spears. Spear-throwers can triple (approx.) the range and accuracy, and are very simple to make. The strength of bows can be vastly increased with the addition of joints and 'springs' made from animal sinew or leather strips. Incidentally, when using such things, make sure that any hunters stay together and that nobody else gets within a kilometre of them. It's critical to know where such activity is going on so no one gets killed by a overshot.
There are dozens of kinds of effective traps, but should be specialized for what you want to catch. Something strong enough to capture or kill an adult boar would totally destroy a rabbit or not be triggered by it (except for pits, which have some drawbacks but are foolproof).
Don't waste a good needle trying to make a fishhook out of it. Unless you heat it just right, it'll snap when you try to bend it. Save it and any real thread for medical emergencies. Make bone hooks and fabric-sewing needles, since they don't need any particular sophistication. If the clothing is to be made of leather or furred hide, it's easier to sew by using an awl and inserting the lace after.
This part is just my personal approach to shelter, because I like fully enclosed places that are easily guarded. If any kind of cave is available, I'd heave a couple of hot, smoky torches in as far as possible to flush out whatever is living there and then build some sort of cover for the entrance to keep it out and maintain dryness. There should be a fire just inside the entrance at all times, with some sort of deflector to send the smoke outside.
Oh yeah... with a mixed population, any chemists in the crowd should see what they can do about finding some naturally-occurring spermicide.
As a last resort, for any additional insulation or bedding materials we can just shave Astronuc every couple of days.

  • #41
So, the first night was uncomfortable, "we relocated to the water source",
Found some rough bedding, and we arranged a guard rota, two people two Hr
shifts, and the rest of us slept.
In the morning we discuss our talents, astronuk is a good builder and boar
hunter, Danger is good at weaponry and hunting, Moonbear is a good cloths maker and butcher, I am a good scavenger, and quite inventive.
So i propose Astrnuk with four others find a site to build a shelter, big enough
for all, and reasonably close to water." we can all chip in on the heavy stuff".
Danger starts making weapons and traps with another four people.
Moonbear and four more find a way to clothe us all and set up some kind of kitchen
I and the remaining four start searching the area for anything edible or of some
use.
Suggestions ?

Is the plane useful for a shelter, and how close to the water supply? The skin can be polished for reflectors.

As for the Whisky - Nuts! The horror of it all.

Yes - priority is a still - made from aircraft parts. Someone has to blow out the hydraulic lines. :biggrin:

Most bombers had radial engines. Which kind of bomber is it? Pacific could mean a B-29.

If you can do the skinning, I can do the tanning. I tried to skin a rabbit once, found it very difficult. I know how to skin a deer properly, but I'm sure it might be more tricky in real life.

Before tanning, we can keep hides fresh by salting them, until we have enough fresh water to clean them. We then soak the hides in fresh water for a couple of days to clean them of the bulk of the fat, and any traces of salt. Ideally, we'd then soak them in a lime solution for a few days, but if this isn't feasible we can remove the hair and epidermis by scraping the hide. We then remove the fat by scraping it off, and slice the leather according to what we want to make (this is the tricky part, - you "shave" it, to get it to the desired thickness). To tan the leather, we soak it in tannins which we've extracted from vegetable matter, I'm sure Moonbear can get this arranged. Again, it's soaked for a few days, before being dried, and finished by rubbing in fish oil, or tallow to provide a nice, waterproof finish, and to seal the leather.

Hey presto, clothes!

Are there any sections of the fuselage that are sufficiently intact to provide a roof over our heads? It would save a lot of labor and time if we can just sleep under a big hunk of metal.

No medicinal whiskey? DARN! Whisky has SOOOO many uses! With parts from that bomber, we probably can build a halfway decent still though, and there really are useful purposes for alcohol, including disinfecting wounds and to use as a lamp or burner inside our shelter if our fire gets rained on. Of the group we have so far, I think Danger, brewnog, Astronuc and Wolram are the team best capable of sorting through the wreckage to determine what's useable and what can be built from the parts. Oh, and is there a toolkit aboard the plane? We may be able to supplement our tools. A few shards of broken glass would be much appreciated in our kitchen/butcher shop. Any weapons aboard that plane that can be restored to working condition? If there are, let's not waste what small amount of ammo we may have there on hunting unless Danger's bows and arrows and traps don't work, it's better to save those in case of a boar attack where we need stopping power fast!
