Knut and Torstein were always doing something with their wet dry batteries, soldering irons, and circuits. All their wartime training was required to keep the little radio station going in spray and dew a foot above the surface of the water.
An unusual bedfellow. We were the first to see a living snake mackerel (Latin name Gempylus). It jumped on board one night and got into Torstein’s sleeping bag.
A bout with a tunny was an exciting sport. There were fish enough in the sea to feed a whole flotilla of rafts.
Inside the bamboo cabin we were protected against both wind and tropical sun. The walls were of plaited bamboo and the roof of banana leaves, so that we almost felt we were in a virgin forest instead of at sea. From left: Watzinger, Haugland, Raaby, Danielsson, the author.

Beneath Kon-Tiki’s bearded face. The head on the sail was copied from a stone carving of Kon-Tiki, the prehistoric chieftain who led a fair-skinned civilized people across the Pacific 1,500 years ago.
Windless weather and tropical heat troubled us very little. When the sea was calm, we made long trips in our little rubber boat.
Every night they took turns sending our reports and weather observations out into the ether, where they were picked up by chance radio amateurs who passed the reports on to the Meteorological Institute in Washington and other destinations. Erik was usually sitting patching sails and splicing ropes, or carving in wood and drawing sketches of bearded men and odd fish. And at noon every day he took the sextant and mounted a box to look at the sun and find out how far we had moved since the day before. I myself had enough to do with the logbook and reports and the collecting of plankton, fishing, and filming. Every man had his sphere of responsibility, and no one interfered with the others’ work. All difficult jobs, like steering watch and cooking, were divided equally. Every man had two hours each day and two hours each night at the steering oar. And duty as cook was in accordance with a daily roster. There were few laws and regulations on board, except that the night watch must have a rope round his waist, that the lifesaving rope had its regular place, that all meals were consumed outside the cabin wall, and that the “right place” was only at the farthest end of the logs astern. If an important decision was to be taken on board, we called a powwow in Indian style and discussed the matter together before anything was settled.
An ordinary day on board the Kon-Tiki began with the last night watch shaking some life into the cook, who crawled out sleepily on to the dewy deck in the morning sun and began to gather flying fish. Instead of eating the fish raw, according to both Polynesian and Peruvian recipes, we fried them over a small primus stove at the bottom of a box which stood lashed fast to the deck outside the cabin door. This box was our kitchen. Here there was usually shelter from the southeast trade wind which regularly blew on to our other quarter. Only when the wind and sea juggled too much with the primus flame did it set fire to the wooden box, and once, when the cook had fallen asleep, the whole box became a mass of flames which spread to the very wall of the bamboo cabin. But the fire on the wall was quickly put out when the smoke poured into the hut, for, after all, we had never far to go for water on board the Kon-Tiki.
The smell of fried fish seldom managed to wake the snorers inside the bamboo cabin, so the cook usually had to stick a fork into them or sing “Breakfast’s ready!” so out of tune that no one could bear to listen to him any longer. If there were no sharks’ fins alongside the raft, the day began with a quick plunge in the Pacific, followed by breakfast in the open air on the edge of the raft.
The food on board was above reproach. The cuisine was divided into two experimental menus, one dedicated to the quartermaster and the twentieth century, one to Kon-Tiki and the fifth century. Torstein and Bengt were the subjects of the first experiment and restricted their diet to the slim little packages of special provisions which we had squeezed down into the hole between the logs and the bamboo deck. Fish and marine food, however, had never been their strong suit. Every few weeks we untied the lashings which held down the bamboo deck and took out fresh supplies, which we lashed fast forward of the bamboo cabin. The tough layer of asphalt outside the cardboard proved resistant, while the hermetically sealed tins lying loose beside it were penetrated and ruined by the sea water which continually washed round our provisions.
Kon-Tiki, on his original voyage across the sea, had no asphalt or hermetically sealed tins; nevertheless he had no serious food problems. In those days, too, supplies consisted of what the men took with them from land and what they obtained for themselves on the voyage. We may assume that, when Kon-Tiki sailed from the coast of Peru after his defeat by Lake Titicaca, he had one of two objectives in mind. As the spiritual representative of the sun among a solely sun-worshiping people, it is very probable that he ventured straight out to sea to follow the sun itself on its journey in the hope of finding a new and more peaceful country. An alternative possibility for him was to sail his rafts up the coast of South America in order to found a new kingdom out of reach of his persecutors. Clear of the dangerous rocky coast and hostile tribes along the shore, he would, like ourselves, fall an easy prey to the southeast trade wind and the Humboldt Current and, in the power of the elements, he would drift in exactly the same large semicircle right toward the sunset.
Whatever these sun-worshipers’ plans were when they fled from their homeland, they certainly provided themselves with supplies for the voyage. Dried meat and fish and sweet potatoes were the most important part of their primitive diet. When the raftsmen of that time put to sea along the desert coast of Peru, they had ample supplies of water on board. Instead of clay vessels they generally used the skin of giant bottle gourds, which was resistant to bumps and blows, while even more adapted to raft use were the thick canes of giant bamboos. They perforated through all the knots in the center and poured water in through a little hole at the end, which they stopped with a plug or with pitch or resin. Thirty or forty of these thick bamboo canes could be lashed fast along the raft under the bamboo deck, where they lay shaded and cool with fresh sea water—about 79° Fahrenheit in the Equatorial Current—washing about them. A store of this kind would contain twice as much water as we ourselves used on our whole voyage, and still more could be taken by simply lashing on more bamboo canes in the water underneath the raft, where they weighed nothing and occupied no space.
We found that after two months fresh water began to grow stale and have a bad taste. But by then one is well through the first ocean area, in which there is little rain, and has arrived in regions where heavy rain showers can maintain the water supply. We served out a good quart of water per man daily, and it was by no means always that the ration was consumed.
Even if our predecessors had started from land with inadequate supplies, they would have managed well enough as long as they drifted across the sea with the current, in which fish abounded. There was not a day on our whole voyage on which fish were not swimming round the raft and could not easily be caught. Scarcely a day passed without flying fish, at any rate, coming on board of their own accord. It even happened that large bonitos, delicious eating, swam on board with the masses of water that came from astern and lay kicking on the raft when the water had vanished down between the logs as a sieve. To starve to death was impossible.
The old natives knew well the device which many shipwrecked men hit upon during the war—chewing thirst-quenching moisture out of raw fish. One can also press the juices out by twisting pieces of fish in a cloth, or, if the fish is large, it is a fairly simple matter to cut holes in its side, which soon become filled with ooze from the fish’s lymphatic glands. It does not taste good if one has anything better to drink, but the percentage of salt is so low that one’s thirst is quenched.
The necessity for drinking water was greatly reduced if we bathed regularly and lay down wet in the shady cabin. If a shark w
as patrolling majestically round about us and preventing a real plunge from the side of the raft, one had only to lie down on the logs aft and get a good grip of the ropes with one’s fingers and toes. Then we got several bathfuls of crystal-clear Pacific pouring over us every few seconds.
When tormented by thirst in a hot climate, one generally assumes that the body needs water, and this may often lead to immoderate inroads on the water ration without any benefit whatever. On really hot days in the tropics you can pour tepid water down your throat till you taste it at the back of your mouth, and you are just as thirsty. It is not liquid the body needs then, but, curiously enough, salt. The special rations we had on board included salt tablets to be taken regularly on particularly hot days, because perspiration drains the body of salt. We experienced days like this when the wind had died away and the sun blazed down on the raft without mercy. Our water ration could be ladled into us till it squelched in our stomachs, but our throats malignantly demanded much more. On such days we added from 20 to 40 per cent of bitter, salt sea water to our fresh-water ration and found, to our surprise, that this brackish water quenched our thirst. We had the taste of sea water in our mouths for a long time afterward but never felt unwell, and moreover we had our water ration considerably increased.
One morning, as we sat at breakfast, an unexpected sea splashed into our gruel and taught us quite gratuitously that the taste of oats removed the greater part of the sickening taste of sea water!
The old Polynesians had preserved some curious traditions, according to which their earliest forefathers, when they came sailing across the sea, had with them leaves of a certain plant which they chewed, with the result that their thirst disappeared. Another effect of the plant was that in an emergency they could drink sea water without being sick. No such plants grew in the South Sea islands; they must, therefore, have originated in their ancestors’ homeland. The Polynesian historians repeated these statements so often that modern scientists investigated the matter and came to the conclusion that the only known plant with such an effect was the coca plant, which grew only in Peru. And in prehistoric Peru this very coca plant, which contains cocaine, was regularly used both by the Incas and by their vanished forerunners, as is shown by discoveries in pre-Inca graves. On exhausting mountain journeys and sea voyages they took with them piles of these leaves and chewed them for days on end to remove the feelings of thirst and weariness. And over a fairly short period the chewing of coca leaves will even allow one to drink sea water with a certain immunity.
We did not test coca leaves on board the Kon-Tiki, but we had on the foredeck large wicker baskets full of other plants, some of which had left a deeper imprint on the South Sea islands. The baskets stood lashed fast in the lee of the cabin wall, and as time passed yellow shoots and green leaves of potatoes and coconuts shot up higher and higher from the wickerwork. It was like a little tropical garden on board the wooden raft.
When the first Europeans came to the Pacific islands, they found large plantings of sweet potatoes on Easter Island and in Hawaii and New Zealand, and the same plant was also cultivated on the other islands, but only within the Polynesian area. It was quite unknown in the part of the world which lay farther west. The sweet potato was one of the most important cultivated plants in these remote islands where the people otherwise lived mainly on fish, and many of the Polynesians’ legends centered round this plant. According to tradition it had been brought by no less a personage than Tiki himself, when he came with his wife Pani from their ancestors’ original homeland, where the sweet potato had been an important article of food. New Zealand legends affirm that the sweet potato was brought over the sea in vessels which were not canoes but consisted of “wood bound together with ropes.”
Now, as is known, America is the only place in the rest of the world where the potato grew before the time of the Europeans. And the sweet potato Tiki brought with him to the islands, Ipomoea batatas, is exactly the same as that which the Indians have cultivated in Peru from the oldest times. Dried sweet potatoes were the most important travel provisions both for the seafarers of Polynesia and for the natives in old Peru. In the South Sea islands the sweet potato will grow only if carefully tended by man, and, as it cannot withstand sea water, it is idle to explain its wide distribution over these scattered islands by declaring that it could have drifted over 4,000 sea miles with ocean currents from Peru. This attempt to explain away so important a clue to the Polynesians’ origin is particularly futile seeing that philologists have pointed out that on all the widely scattered South Sea islands the name of the sweet potato is kumara, and kumara is just what the sweet potato was called among the old Indians in Peru. The name followed the plant across the sea.
Another very important Polynesian cultivated plant we had with us on board the Kon-Tiki was the bottle gourd, Lagenaria vulgaris. As important as the fruit itself was the skin, which the Polynesians dried over a fire and used to hold water. This typical garden plant also, which again cannot propagate itself in a wild state by drifting across the sea alone, the old Polynesians had in common with the original population of Peru. Bottle gourds, converted into water containers, are found in prehistoric desert graves on the coast of Peru and were used by the fishing population there centuries before the first men came to the islands in the Pacific. The Polynesian name for the bottle gourd, kimi, is found again among the Indians in Central America, where Peruvian civilization has its deepest roots.
In addition to a few chance tropical fruits, most of which we ate up in a few weeks’ time before they spoiled, we had on board a third plant which, along with the sweet potato, has played the greatest part in the history of the Pacific. We had two hundred coconuts, and they gave us exercise for our teeth and refreshing drinks. Several of the nuts soon began to sprout, and, when we had been just ten weeks at sea, we had half a dozen baby palms a foot high, which had already opened their shoots and formed thick green leaves. The coconut grew before Columbus’ time both on the Isthmus of Panama and in South America. The chronicler Oviedo writes that the coconut palm was found in great numbers along the coast of Peru when the Spaniards arrived. At that time it had long existed on all the islands in the Pacific.
Botanists have still no certain proof in which direction it spread over the Pacific. But one thing has now been discovered. Not even the coconut, with its famous shell, can spread over the ocean without men’s help. The nuts we had in baskets on deck remained eatable and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it. It was the eyes of the coconut which sucked in the sea water so that the nut spoiled. Refuse collectors, too, all over the ocean took care that no edible thing that floated should get across from one world to the other.
Solitary petrels and other sea birds which can sleep on the sea we met thousands of sea miles from the nearest land. Sometimes, on quiet days far out on the blue sea, we sailed close to a white, floating bird’s feather. If, on approaching the little feather, we looked at it closely, we saw that there were two or three passengers on board it, sailing along at their ease before the wind. When the Kon-Tiki was about to pass, the passengers noticed that a vessel was coming which was faster and had more space, and so all came scuttling sideways at top speed over the surface and up on to the raft, leaving the feather to sail on alone. And so the Kon-Tiki soon began to swarm with stowaways. They were small pelagic crabs. As big as a fingernail, and now and then a good deal larger, they were tidbits for the Goliaths on board the raft, if we managed to catch them.
The small crabs were the policemen of the sea’s surface, and they were not slow to look after themselves when they saw anything eatable. If one day the cook failed to notice a flying fish in between the logs, next day it was covered with from eight to ten small crabs, sitting on the fish and helping themse
lves with their claws. Most often they were frightened and scurried away to hide when we came in view, but aft, in a little hole by the steering block, lived a crab which was quite tame and which we named Johannes.
Like the parrot, who was everyone’s amusing pet, the crab Johannes became one of our community on deck. If the man at the helm, sitting steering on a sunshiny day with his back to the cabin, had not Johannes for company, he felt utterly lonely out on the wide blue sea. While the other small crabs scurried furtively about and pilfered like cockroaches on an ordinary boat, Johannes sat broad and round in his doorway with his eyes wide open, waiting for the change of watch. Every man who came on watch had a scrap of biscuit or a bit of fish for him, and we needed only to stoop down over the hole for him to come right out on his doorstep and stretch out his hands. He took the scraps out of our fingers with his claws and ran back into the hole, where he sat down in the doorway and munched like a schoolboy, cramming his food into his mouth.
The crabs clung like flies to the soaked coconuts, which burst when they fermented, or caught plankton washed on board by the waves. And these, the tiniest organisms in the sea, were good eating too even for us Goliaths on the raft, when we learned how to catch a number of them at once so that we got a decent mouthful.
It is certain that there must be very nourishing food in these almost invisible plankton which drift about with the current on the oceans in infinite numbers. Fish and sea birds which do not eat plankton themselves live on other fish or sea animals which do, no matter how large they themselves may be. Plankton is a general name for thousands of species of visible and invisible small organisms which drift about near the surface of the sea. Some are plants (phyto-plankton), while others are loose fish ova and tiny living creatures (zoo-plankton). Animal plankton live on vegetable plankton, and vegetable plankton live on ammonia, nitrates, and nitrites which are formed from dead animal plankton. And while they reciprocally live on one another, they all form food for everything which moves in and over the sea. What they cannot offer in size they can offer in numbers.
